• Q: Do reboot, slave switch and manual reset active RSU have the same effect?on NE16E/NE08E?[Top]

    The two products of NE16E and NE08E in high-end router products are all double main controlled, but when the double RSU are all in position, executing reboot, slave switch or manual reset active RSU (press reset key) under active RSU command are all to process active switchover. This is different from NE80, NE40-8, and NE40-4, which executing reboot whole router is to restart overall system, and executing slave switch is to process active switchover.Please notice it.

  • Q:How many links are supported as MP by a mid-range Quidway router? [Top]

    At most 100 links are supported for binding in VRP1.65 version. If USING E1 mode is adopted for E1, it is allowed to bind 28 links altogether. But in the case of slot-division binding, 28 E1s can generate 28 x 31 = 868 links. Then only 100 links can be bound, and other links cannot.

  • Q:How to connect two RS232DTE devices with an empty MODEM cable?[Top]

    In practical project, two RS232-DTE devices are often required to be directly interconnected. For example, two computers are directly interconnected via a serial port, and a router is connected with a dumb terminal via V.24-DTE cable. In this case, an empty MODEM cable can be used for connecting. The empty MODEM cable can be made according to the following method: 25-pin 9-pin 9-pin 25-pin FG (Frame Ground) 1 - X - 1 FG TD (Transmit Data) 2 3 - 2 3 RD RD (Receive Data) 3 2 - 3 2 TD RTS (Request To Send) 4 7 - 8 5 CTS CTS (Clear To Send) 5 8 - 7 4 RTS SG (Signal Ground) 7 5 - 5 7 SG DSR (Data Set Ready) 6 6 - 4 20 DTR DTR (Data Terminal Ready) 20 4 - 6 6 DSR Additionally, for some devices, it is necessary to make pins 6 and 8 of DB25, and pins 1 and 6 of DB9 in short-connection to provide DCD signals.

  • Q: How many kinds of voice modules are available in mid-range and low-end Quidway routers? [Top]

    Currently, a mid -rang or low-end router provides following voice interface cards: AL, AT, FXS, FXO, E&M and E1VI. Among which, AL and AT modules are the products delivered earlier. AL module is FXS module, while AT module is FXO module. Specifically, Foreign exchange station (FXS) that most people are familiar with is interface used for connecting a standard analogue phone set. FXS interface is the basic phone device used for connecting a phone set, modem, fax and analog switch. Foreign exchange office (FXO): The port of standard phone set is an FXO interface. A router with voice function adopts FXO port to connect the PSTN interface. Just like a standard phone set, the FXO interface requires dial-up tone to make a call. The device with FXO interface can only be interconnected with the device with FXS interface. E&M interface is often called Ear & Mouth or recEive & transMit. Hook-on and hook-off signals are provided by E&M signals, and the interferences are weakened. E&M signals are often used in the backbone PBX or the connection line. This interface supports the analogue E&M signaling. It divides the voice connection at the trunk circuit side and the signaling unit side (like the relationship between DCE and DTE). PBX transmits signals to the router over line M, and receives signals from the router via line E. E&M at each port can only process 1 channel of voice signal. E1VI module is to meet the requirement of processing dense signals in VoIP system. It completes the VoIP function on E1 line, and realizes the voice transmission mode compatible with data transmission. It can provide a E1 interface for users to complete the processing of 30-channel voice signals with the structure of backplane combined with pinch board. The interface cable of E1VI module is 120 ohm cable in compliance with Standard G.703. The cable is terminated with a DB-15 connector at the router end, and an RJ-45 connector at the network end. The interface bandwidth is 2.048Mbit/s, which is divided into 32 time slots (TS0~TS31). The bandwidth of each time slot is 64kbit/s, which supports R2 and DSS1 signaling.

  • Q:What are the configuration methods to disable a user TELNET accessing to a low-end or mid-range router? [Top]

    To disable some telnets: Configure an Access Control List (ACL), with the deny source being a user's host, the destination being a router, and the port being tcp packet at port 23. To disable all telnets: Set login telnet command, but do not set any exec user. Then, a telnet user will be authenticated when he log in to the system. And he will not pass the authentication as no user name is set.

  • Q:Are the VIU boards of NE05 and NE08E/NE16E universal? [Top]

    In delivery, two types of VIU boards are available, i.e., VIUA and VIUB, which correspond to 128M and 256M memories. VIUA is used for NE05, while VIUB is used for NE08E and NE16E. Besides the different memory sizes of the two types of VIU, a hard identity position is also provided, which is fixed on the VIU board in delivery. Therefore, VIUA of NE05 cannot be registered if it is inserted in NE08E/NE16E.

  • Q:What are the requirements of framing setting when NE16/08 and the E1 interfaces of mid-range and low-end routers are communicating? [Top]

    For the framing mode of E1 interface in NE16/08 product, the default modes of different service cards are different due to applying chip. By default, it is no crc4 for 4E1/8E1 card, and crc4 for CPOS and E3 cards. By default, E1 card of mid-range and low-end routers are no crc4. In the process of deployment and maintenance, it should be noted that the framing types at two ends of the device must be consistent. Otherwise, such problems as packet loss will occur in application.

  • Q:How does NE16E identify the active RSU and standby RSU via an indicator? [Top]

    MOTO platform: There are a row of indicators on the front panel shelf of MOTO platform, and "RUN" and "MST" indicator on slot position 6 and 8 respectively. Indicator RUN indicates operation of board CPU (long-term on indicates operating normally), indicator MST on only one slot position can be on. If it is on, it indicates RUS on this slot position is the active. It also can identify the active RSU through the indicator on the back board. There are 3 indicators on the HAU board of MOTO platform, "In service" indicator on one HAU board will be on when two boards are also in position. If the indicator on slot position 7 is on, RSU 6 is the active. If the indicator on slot position 9 is on, RSU 8 is the active (Note: It is different from the matching of 6 and 9, 7 and 8, which we are familiar with). Platform produced by Chinese manufactuers: No indicator is available in the plug-in box of the platform produced by Chinese manufacturers, and all indicators are provided on the corresponding board. For RSU, DOMA/DOMB is used to identify the active and standby RSU. If both DOMA and DOMB indicators of a certain RSU are on, it indicates the active RSU. Likewise, the platform produced by Chinese manufacturers can also identify the active/standby RSU via indicators at the rear boar. Both DOMA and DOMB indicators are provided in the HAU produced by Chinese manufacturers. If DOMA and DOMB indicators of No.9 HAU are on, No. 6 RSU is the active RSU; If DOMA and DOMB indicators of No.7 HAU are on, No. 8 RSU is the active RSU (the same as the match between No.6 and No.9, No.7 and No.8, which we are familiar with).

  • Q:How to expand the memory when mid-range 8240CPU routers R262 X, R263X and R36XXE are adopted? [Top]

    1. Two memory slots are available for R3680E, R3640E, R2631E and R2630E. If only 1 slot (close to CPU)is used, 32M, 64M and 128M memories are allowable. But in the case of expansion, slot 1 must be inserted in a 128M memory. The optional combinations are as follows: One slot Two slots 128M 32M 128M 64M 128M 128M 2. Only one memory slot is available for R2620 and R2621, which supports 32M, 64M and 128M memories. 3. By default, R36XXE is for 128M memory; R263XE is for 64M memory; R262X is for 32M memory.

  • Q: What is the maximum length of the telephone line between the interface of router FXS and the phone set? [Top]

    The length of less than 200 meters is recommended. Note: The telephone line connected with FXS can only run indoors. In the case of outdoor cabling, serious interference may be caused, the voice quality may be degraded, and even the whole router may be damaged due to the lightning strike!

  • Q:Why can not use dialer bundle command when the PPPoE client with mid-range router configuration dial?[Top]

    PPPoE dial adopts shared DCC dial mode, it need to create dialer port, then bind the physical interface and dialer bundle. The implication of dialer bundle is to enable shared mode, while DCC shared mode and circular dial mode can not be used at the same time, so it need to use undo dialer enable-circular to disable circular dial mode. The user often meets with the problem that the dialer bundle command cannot be found, which is always because dialer enable-circular has been configured under the dialer port.

  • Q:Is it possible to configure X.25 svc to the subinterface of interface X.25 at Quidway routers?[Top]

    Impossible X.25 subinterface is only a logic concept, and has no real transceiver interface, so all data transceiver of subinterface completely depends on the control block of main interface. In addition, X.25 subinterface can not configure X.121 address, so, any packet transceiver must depend on the main interface.

  • Q:What are the precautions when useing E1-F interface module and CPOS module for E1 access? [Top]

    Currently high end router adopts CPOS interface, and mid-range router adopts E1-F interface, which has formed an optional scheme of E1 access and convergence. E1-F refers to the fractionated E1, which supports two operational modes of framed and unframed. Its framed mode is different from E1/CE1/PRI modules in that it cannot bind time slots randomly and can only bind 1 to 31 time slots into one channel on one interface. Currently, E1 disassembled from CPOS interface can only bind time slots 1 to 31 into one channel when it applies to non-channelized mode. So, it should notify the selection of operation mode when interconnecting them.

  • Q:In performing NAT on NE80, if there is only one public network IP of upstream interface and no other public network address used for address pool, what to do?[Top]

    The current versions of NE80 still do not support interface address mode NAT, which relate to NAT implementation. If there is an upstream interface, the problem can be solved by adopting the address unnumbered of the upstream interface or the public network address left used for NAT address pool. But this mode has definite limitation that it needs upstream interface as POS interface, otherwise it cannot borrow address.

  • Q:Why cannot find the command matching GK interworking mode in VRP 1.74?[Top]

    The voice gateway of router will intercommunicate with GK Servers produced by different manufacturers normally, so it needs to adopt matching interworking mode. Currently GK Server can be product of Huawei or other companies. The former versions needs manual setting of GK interworking mode, but VRP 1.74 does not need setting, and the router can adjust as GK Server mode.

  • Q: Mid-range router dial with ether interface PPPOE. After dial-on, why does the Ethernet interface link protocol always down?[Top]

  • Q:What is the black hole route? What does the black hole route functions to prevent the route loop?[Top]

    Black hole route is actually a kind of special static route, just as its name implies, the data packet with a destination address in this network segment will be discarded after it arrives at the device. With this feature of the black hole route, a route loop can be avoided in the actual networking. As shown in the following figure, Switch S is configured with 8 VLAN layer-3 interfaces used for the user's access, which are respectively 1.1.0.1/24 ~ 1.1.7.1/24. Meanwhile, Switch S is configured with a default route that points to router R, which is configured with a roundtrip route 1.1.0.0/21 that points back to Switch S. In normal cases, this network does not fail. But after one of the layer-3 interfaces of Switch S is down, the data will be forwarded in a circulative mode between Switch S and Router R to form a route loop if data packets are transmitted to this VLAN. To solve this problem, Switch S can be configured with a "black hole route". ip route 1.1.0.0 255.255.248.0 null 0 Then the route loop can be effectively avoided.

  • Q:What is the max. length of the telephone line from the FXS port of router to the phone set?[Top]

  • Q:Under which circumstances does silent-interface be used for OSPF configuration? [Top]

    We usually use "Import direct" feature to advertise its direct-connected link to the whole domain. But in this case, External LSA packet will be used and advertised to the whole area, except stub area. To limit the advertisement within some specific area, we can use "network" command to enable OSPF in an interface, and use silent-interface to keep the interface from sending hello packet to form neighbor connection, then the directly-connected link can be advertised internally.

  • Q:New username/password have been added in Quidway router, but it can not be used for remote login, why?[Top]

    • Q: The indicators of WBR204g work normally and I can also access BBS successfully, but I cannot visit websites all the while. Why? [Top]

      Check first the configuration page of WBR204g, it should show that DNSs have been obtained normally on the "WAN status" page. Then ensure that the DNSs of hosts in LAN are configured as these DNSs, or as IP maintained by the LAN port of WBR204g. For Windows2000 or WinXP, you may type in "domain name to be analyzed by nslookup" to verify the status of DNS.

    • Q:The device in normal use powers off in a sudden; and normal access to the network fails after the device is restarted, why? [Top]

      This may be caused by ISP device. Wait for five minutes if dial-up failure appears on the status page after the restart, and then check the WAN status again. You can retry to access the network if dial-up is successful and WAN IP has been obtained.

    • Q: All indicators work normally, but network access is often cut off. Why?[Top]

      1. Forced offline by ISP central office for some special reasons. You can directly access the network without using the WBR204g device to check if it is caused by the configuration of WBR204g device. 2. To avoid bandwidth waste, some ISPs may set time limit for offline in the case of non-operation. Forced offline by ISP may occur if no operation happens for a long time and no service traffic runs on the line. 3. This may be caused by device hardware if ISP confirms the normal status of line. Contact your supplier to solve it.

    • Q: How to make wireless access safer?[Top]

      The security of wireless access is vital for users due to the publicity of transmission medium of wireless signal. The following methods can improve your data security of wireless access: 1. Forbidding broadcasting SSID. But, users need to type in SSID manually when they themselves adopt wireless access. 2. Enabling MAC address filtering to add MAC addresses of network cable and network card allowable for access to the filtering table. Thus, wireless network cards unavailable in this table will be denied. 3. Enabling wireless network encryption. Family users can choose WEP 64/128 bits or WPA Pre-shared Key. Small-/medium-sized enterprise users can choose WPA but Radius Server needs to be deployed. The above Step 1 and 2 are very simple to implement, and Step 3 is suitable for SOHO office users.

    • Q:My operating system is Windows 98 or Windows 2000, and others cannot use voice chat to communicate with me through MSN. What shall I do？[Top]

      Windows XP has been loaded with UPnP device, whose UPnP IGD function does not affect normal communication between multiple MSN users in LAN and the Internet. But for Windows2000 users or Windows98 users with UPnP module not installed, they can use the following methods to solve the problem: 1. For Windows98 users, they can install it through the network installation wizard of WindowsXP installation CD and upgrade IE to version 6.0. 2. You can initiatively call others, but you cannot share photos with them through MSN. 3. For audio and file transmission, it can be put in DMZ area if only one PC needs this service; otherwise, for file transmission, it is required to enable the In-and-Out TCP connection at the ports from 6891 to 6900 of the server. Thus, each MSN Messenger user can transfer 10 files at most each time. If only the port 6891 is enabled, users can only transfer one file at one time. Enabling UDP to connect with 1863 and the ports from 5004 to 65535 allows using the audio/video communication function. If the remote desktop sharing is required, configure the virtual server at the TCP3389 port; if the application sharing and whiteboard sharing are required, configure the virtual server at the TCP1503 port. If it still fails, configure the virtual servers at the TCP&UDP 6901 and UDP 5190 ports. For details, consult Microsoft or visit the website: http://www.microsoft.com/windowsxp/pro/techinfo/deployment/natfw/default.asp But, this service cannot be implemented if both parties are behind the firewall or NAT.

    • Q:How to make the device support NetMeeting?[Top]

But, actually, even if the TCP1720 port triggers these ports, the voice setup may still be unsuccessful because this device currently cannot implement the H.323 gateway. WBR204g does not recommend using this method. Contact Microsoft for more information on Netmeeting.

    • Q:How to make the device support BitTorrent downloading?[Top]

      Since the device enables NAT, the upload rate will be slow with BT downloading if no virtual server is configured, and thus the download rate returned by BT according to the upload rate will be also slow. To use BT resource effectively, use the TCP6881 port to trigger the ports from TCP6882 to TCP6889, or configure virtual server for these nine ports.

    • Q:What are the typical networking modes for BR304 and what kinds of networking are forbidden?[Top]

      Feasible Networking Modes: 1. BR304 (Center)----BR304 (Subdivision) One center matches one subdivision. The IP addresses of both sides are dynamic. This mode can cooperate with DDNS setting. 2. BR304 (Center)----BR304 (Subdivision) ----BR304 (Subdivision) ----BR304 (Subdivision) ----BR304 (Subdivision) ----BR304 (Subdivision) One center matches five subdivisions at most. The IP addresses are all dynamic ones. This mode can cooperate with DDNS setting. 3. BR304 (Center)----BR304 (Five BR304s at most are allowed to connect simultaneously to the center) The IP addresses of both sides are fixed ones. 4. BR304 (Center)----BR304 (Dynamic IP address)[Five BR304s at most are allowed to connect simultaneously to the center] The IP address of one side is fixed, and that of another side is dynamic. And only the dynamic IP side can initiate the VPN connection. 5. BR304----R263xE/R36XXE BR304---- BR304---- BR304---- The VRP3.3 mid-range routers are used in the center. The subdivision's BR304s, the number of which is unlimited, are connected to the center in the aggressive IPSec mode. 6. PC----BR304 PC---- PC---- PC---- PC---- The PCs are connected to the center's BR304 in the out-of-box ”IPSec setting in the PC crypto map” mode of the win2000/xp. The IP address for BR304 had better be fixed. It is complex to set PC. For the setting method, refer to http://forum.H3C.com/viewthread.php?tid=5859 Fixed IP for BR304 + Fixed IP for PC = You need not modify any setting when PC is connected to BR304 Fixed IP for BR304 + Dynamic IP for PC = You must manually modify the setting of PC when PC is connected to BR304 Dynamic IP for BR304 + Fixed IP for PC = You must manually modify the setting of PC when PC is connected to BR304 Dynamic IP for BR304 + Dynamic IP for PC = You must manually modify the setting of PC when PC is connected to BR304 Note: Five PCs at most can be allowed to connect simultaneously to BR304 in IPSec VPN mode. Unfeasible Networking Modes: 1. BR304----PC (on which the cisco vpn client is installed) 2. BR304----PC (on which the win2000/xp out-of-box l2tp and ipsec virtual private network dial software is used) 3. BR304 (center, in the aggressive IPSec mode)----BR304 (subdivision, in the aggressive IPSec mode) 4. The l2tp access, pptp access and l2p access 5. Currently, no software client (except the local crypto map of win2000/xp) on the PC can access to BR304.

    • Q:The mac for the Aolynk broadband router WAN port is modified strangely so that the connected PC cannot access the network. What can I do?[Top]

      1.“Status record” shows that the mac address for WAN port is 00-00-00-FF-FF-FF. 2.“WAN” modifies “PPPoE” as “Dynamic Address”. 3.“Modify the MAC address as MAC address for PC”. 4.“WAN” modifies “Dynamic Address” as “PPPoE”. 5.Fill in correctly the user name and password, and you can access the network. The fault appears seldom. The problems have been solved in the latest (unpublished) version.

    • Q: How does the Aolynk broadband router network?[Top]

      The most common networking modes are: 1. Access the network by sharing ADSL dialup connection PC---Aolynk switch---LAN port (Aolynk broadband router) WAN port ---ADSL modem---Filter---PSTN----------------Internet 2. Access the network by sharing broadband PC---Aolynk switch---LAN port (Aolynk broadband router) WAN port [DHCP acquires address automatically or has a fixed public network IP address]----------------Internet

    • Q:How can I view the mac and IP addresses of a PC?[Top]

      "Start”-->“Run”-->“command”-->“ipconfig/all” MAC Address Physical Address. . . . . . . . . : 00-06-5B-33-A4-BB IP Address IP Address . . . . . . . . . . . . : 192.168.1.140

    • Q:How does a PC fix an IP address and how to use dhcp to acquire IP automatically?[Top]

      Take winxp as an example: Start-->Set-->Network Connection-->Local Connection-->Attribute-->Select “Internet Protocol (TCP/IP)”--> Attribute --> Acquiring IP automatically means that dhcp acquires IP automatically; using the following IP address means to fix the IP address manually.

    • Q:How do I use the ping command?[Top]

      Start-->Run-->command-->ping 192.168.1.1 Request timed out indicates that the opposite end is unreachable. Perhaps the opposite end sets the software firewall. Reply from 192.168.1.1: bytes=32 time=3ms TTL=255 shows that everything is normal.

    • Q:How can I know there is no problem with the dns server a PC uses? [Top]

      DNS means Domain Naming System. It can translate the name of a network node in the Internet into a network address. For example: it translates http://forum.H3C.com into http://211.100.23.227. Take winxp as an example: Start--> Run-->cmd--> ipconfig /all, and you can see DNS Servers . . . . . . . . . . . : 202.99.192.68 The first method: Ping the address to check its reach-ability. The second method: It is the easiest method. Run “nslookup www.google.com” under the DOS promt. Because many DNS Servers may shield the ICMP packets, "ping DNS Server" is not recommended. The third Method: Input http://211.100.23.227 in the ie explorer to view if you can open the web page directly. If you cannot access http://forum.H3C.com but can access the web page by using IP address, it indicates a problem with dns. The telecommunication's DNS: 202.99.192.68 is recommended here.

    • Q:What does UpnP mean? Does my computer support it?[Top]

      The win98 and winxp operation systems support UpnP after setting it up; The win2000/winNT does not support it. The advantages of UPnP are obvious: 1. Allow many PCs in the LAN to run p2p and DirectX games without setting up Virtual Server; 2. For security, the NAT projects can be added and be removed automatically. At present, there are more and more applications support UpnP, such as BT software, UpnP, etc. Note: It is possible that the operation system does not support UpnP. Only if the application supports UpnP, the application can automatically add and remove the NAT project on the UPnP IGD. For details, refer to http://forum.H3C.com/viewthread.php?tid=5961.

    • Q: What are the default user name and password for the administrator of the Aolynk broadband router?[Top]

      User name: admin Password: admin

    • Q:Does the BR broadband router support the transparent transmission PPPoE dialup?[Top]

      Yes. The ADSL dialup is set for the WAN port. You need not fill in the user name and password for the port. The PC connected to the LAN port can directly dial up by using pppoe client. Dial-up access is required for each PC.It is recommended that the user name and password are configured in the setting page of the Aolynk BR broadband router. Therefore, all PCs can access the network directly.

    • Q: How many internal network users does the BR broadband router generally support to access the network simultaneously?[Top]

      The best number is 50, and the most is 253. (The number is related to the service used by the client. When most of the PCs browse the web pages and do not use the BT or other tools to download very large files, the above numbers are recommended.)

    • Q: What's the type of the CPU of the BR broadband router and what's the main frequency of the CPU?[Top]

      They are ARM9 and 166MHz respectively.

    • Q: Does the BR broadband router support the 802.1x authentication?[Top]

      At present, it does not support it.

    • Q:The PC can access to the network with the ADSL modem (such as Alcatel speedtouch515); but it fails with the Aolynk broadband router. What is the reason?[Top]

      Some ADSL modems have much function and have the nat function themselves. Before the Aolynk router is used, please check the IP of the PC while accessing the network with ADSL modem. Method: Start->Run->command->ipconfig If the IP for the PC is 10.*.*.* or 192.168.*.*, it indicates that your ADSL modem provides the nat function. You should reset the ADSL modem at this time to cancel its nat function. Take the Alcatel modem as an example, you should modify it as external pppoe (RFC 1483 bridged) according to the manual. Then you connect the ADSL modem to the router and set the parameters such as user name and password for the Aolynk router. You can access the network now.

    • Q: Why cannot the public network access the http server that internal network map externally to?[Top]

      Cause: Most operators shield completely the 80 port downlinked to the client, even all the 1-1024 ports, including the default ports of the BT software. As a result, the operator devices filter the data packets with which the public network PC accesses the server 80 port of the internal network, thus the public network fails to access the port. To map from the server of internal network to the external network, you must modify the web server’s port by using 3618 or others. More reliable checking method: PC (web server)---ADSL modem---ISP---Internet------------PC (client) The client accesses the Internet through the ADSL modem by dial-up and provides the 80 port web server. If the server does not respond, it indicates that the operator shields the 80 port.
