ET704-B-L optical network unit (ONU) devices (hereinafter referred to as the ET704-B-L), offered by Hangzhou H3C Technologies Co., Ltd. (hereinafter referred to as H3C) for industry and enterprise users, are compliant with Ethernet passive optical network (EPON) interoperability standards and provide outstanding reliability.
The ET704-B-L provides four Ethernet interfaces and one passive optical network (PON) interface, which are compliant with IEEE 802.3ah 1000Base-PX20 transmission specifications. Working with optical line terminals (OLT) through an optical distribution network (ODN), ONUs form a complete EPON system for users, offering various services including data transmission and IPTV. As such, the ET704-B-L offers a good solution for implementing fiber to the home (FTTH) services.
l Compliant with IEEE 802.3ah EPON standards and IEEE 802.3ah 1000Base-PX20 transmission specifications.
l Compatible to OLTs that meet the interconnectivity standards, enabling remote management, maintenance and configuration through OLTs.
l Supporting remote management of Aolynk Group Management Protocol (AGMP) capable switches.
l Supporting remote maintenance and configuration through Telnet.
l Supporting online software upgrade.
l Supporting power outage notification.
l Supporting security features including hierarchical user management, password protection and black hole MAC address list.
l Providing various debugging functions for locating and diagnosing errors.
The ET704-B-L provides a series of configuration commands and command line interfaces (CLIs), allowing users to configure and manage it conveniently.
Features of command line interfaces include:
l Hierarchical command protection, preventing unauthorized users from accessing the ET704-B-L.
l Online help: Users can gain online help at any time by entering a question mark (?).
l Command history function: This enables users to check the commands that they have lately executed and re-execute the commands.
l Fuzzy match of key words by command line interpreter: to interpret a key word, the user simply needs to enter a distinct keyword, such as “disp” for “display”.
ET704-B-L CLI views are designed for different configuration tasks. They are both correlated and distinguishing. For example, once a user logs into the ET704-B-L successfully, the user enters user view, where the user can perform some simple operations such as checking the operation status and statistics information of the ONU. By executing the system-view command, the user enters system view, where the user can go to other views by entering corresponding commands.
The command line interface views include:
l User view
l System view
l Ethernet interface view
l VLAN interface view
l User interface view
Table 2-1 lists the details of the command line interface views, including the functions, the prompt and the entry and exit commands. Note that the interface numbers are for illustration purpose only.

The ET704-B-L has two user levels:
l Guest users: only permitted for some basic query operations in user view.
l Administrative users: permitted to enter system view and perform monitoring, configuration and management operations to the ET704-B-L.
By default, the user does not need to enter any password to enter system view. It is recommended to configure hierarchical user passwords on the ET704-B-L by executing the super password command. For the sake of security, the password entered for authentication is displayed as cipher text. If the correct password is entered within three attempts, the user will be switched to administrative user level. Otherwise, the user stays at guest user level.
Table 2-2 presents the method of configuring hierarchical user passwords.

Users can telnet to the ET704-B-L for remote management and maintenance.
To telnet to the ET704-B-B, both the ET704-B-L and the user terminal need to be properly configured, as listed in Table 3-1.
Table 3-1 Configurations on the ET704-B-L and the user terminal
|
Object |
Configurations required |
|
ET704-B-L |
l If the Telnet user terminal and the ET704-B-L interface where the terminal is connected are in the same local area network (LAN), their IP addresses must be in the same network segment. Otherwise, the Telnet user terminal and the ET704-B-L must be mutually reachable. l By default, the Ethernet interface and management VLAN of the ET704-B-L are down. The user needs to bring them up through operations on the OLT remotely. |
|
Telnet user |
The Telnet program is installed and started. |
|
It has obtained the IP address of the management VLAN of the ET704-B-L, for which you can refer to Management VLAN Configuration. |
& Note:
l Only one user can Telnet to the ET704-B-T at a time.
l By default, the ET704-B-L requires no password for login through Telnet. You are recommended to configure a password after the first time login.
The following gives an example on how to Telnet to the ET704-B-L.
1) As shown in Figure 3-1, connect the Ethernet interface of the Telnet user terminal to that of the ET704-B-L through a LAN.
Figure 3-1 Establish the configuration environment
2) Run Telnet on the user terminal, and enter the IP address of the management VLAN of the Ethernet interface on the ET704-B-L that connects with the terminal (assuming it is 192.168.0.234), as shown in Figure 3-2.
3) The user terminal displays “Password” (assuming that a password is configured). After the user enters the correct password, a command line prompt will appear (such as <H3C>). If themessage “Vty user is busy now” appears, it means there is already a user logged into the ET704-B-T through Telnet.
After logging into the ET704-B-T, you can use the commands to configure it or check its operation status. To obtain the help information, enter a question mark “?” at any place. For detailed information of the configuration commands, refer to the following chapters.
Configuring VTY user interface involves the following three steps:
l Enter VTY user interface view
l Configure terminal properties
l Configure Telnet login password
The VTY user interface view stores the properties of the interface when a specified user Telnets to the ET704-B-L. The ET704-B-L supports only one VTY user interface.

To forward packets, the ET704-B-L needs to maintain a port-based Layer 2 MAC address table, which is the basis of fast forwarding on the ET704-B-L. An entry of the MAC address includes:
l The destination MAC address
l VLAN ID of the interface
l Forwarding interface number
By looking up the MAC address table, the ET704-B-L can find the forwarding interface number for a Layer 2 packet quickly, so as to achieve fast forwarding of Layer 2 packets.
When receiving a packet whose destination MAC address is a black hole MAC address (a special MAC address), the ET704-B-L will discard the packet directly, instead of forwarding it.
The ET704-B-L also provides the MAC address aging function. If no packets are received within a certain time from a device whose MAC address is already in the MAC address table, the ET704-B-L will delete the corresponding entry from the table. The MAC address aging function only applies to entries learned and dynamic entries configured by the user. It does not apply to entries of static MAC addresses and black hole MAC addresses.

The aging time is very important for implementing the MAC address aging function of the ET704-B-L. An aging time being too long or too short will result in a large number of packets which cannot match any entry and need to be broadcast. This will affect the performance of the ET704-B-L. The following gives the reasons:
l If the aging time is too long, the ET704-B-L may keep many MAC address entries that are outdated, consuming the MAC address table resource and disabling the ET704-B-L from updating the MAC address table according to network changes.
l If the aging time is too short, the ET704-B-L may delete valid MAC address entries, thus decreasing its forwarding efficiency.
Follow these steps to configure the aging time of MAC address table entries:

Configure the priority trust mode for the remote switch |
agmp { switch-id switch-id | switch-mac mac-address } priority-trust { port I 802.1p } |
l port: the port priority is used for queueing, that is, packets are put into outgoing queues based on the corresponding port priorities. l 802.1p: the COS priority is used for queueing, that is, packets are put into outgoing queues based on the corresponding COS priorities. |
|
Configure the queue scheduler for the remote switch |
agmp { switch-id switch-id | switch-mac mac-address } queue-scheduler { 4:1 I 8:1 I 16:1| high-first} |
l 4:1: packets are enqueued by priority with the ratio of 4:1. l 8:1: packets are enqueued by priority with the ratio of 8:1. l 16:1: packets are enqueued by priority with the ratio of 16:1. l high-first: packets of high priority are enqueued first. |
& Note:
4:1/8:1/16:1 means that the queueing algorithm used is weighted round robin (WRR), and high-first means the queueing algorithm used is strict priority (SP).
l The WRR algorithm specifies a weight (w0, w1…) for each queue, which represents the weight of resources assigned. With 4:1 configured, if the traffic in two outgoing queues exceeds the capacity of the port, the switch will schedule the packets between the two queues in a ratio of 4:1. That is, out of every 5 packets sent by the switch, 4 are from the high priority queue and one from the low priority queue. The principle is the same for other two ratios 8:1 and 16:1.
l With the strict priority algorithm enabled, if the traffic in two queues exceeds the capacity of the port, the switch will send out packets in the high priority queue first and will send low priority packets after all high priority queues are sent.
The following gives an example of configuring the WRR queueing algorithm with the ratio 4:1 for the switch whose ID is 1.

The ET704-B-L provides various debugging functions covering most of the supported protocols and features, facilitating failure locating and diagnosis.
The export of debugging information can be controlled by either of the following two switches:
l Protocol debugging: controls whether to export the debugging information of a specified protocol.
l Terminal output switch: controls whether to output the debugging information to a specified user terminal.
As shown in Figure 9-1, assume that the ET704-B-L can provide debugging information for modules 1, 2 and 3. However, you need to turn both switches to on to have the debugging information displayed on the terminal.
