debugging tcp event [ task_id socket_id ]
undo debugging tcp event [ task_id socket_id ]
View
User view
Parameter
task_id: Task ID.
socket_id: Socket ID.
Description
Use the debugging tcp event command to enable TCP event debugging.
Use the undo debugging tcp event command to disable TCP event debugging.
When executing this command to enable the debugging, the number of debugging you can enable is limited, that is, you can enable debugging of fixed number (the combination of task ID and socket ID) at one time, besides, a new socket will be created to establish connection if TCP is passively opened or receives connection request, and some applications such as Telnet server will create a new task to process the connection. So you must not use parameters task_id and socket_id if you want to get information on connection establishment.

This command displays traffic statistics of all current UDP connections. Statistics is composed of two parts: the sending part and the receiving part. Each part can be divided into different types of packets, such as checking packets, error packets, and so on. The command can also display statistics information closely related to the connection, such as the number of broadcast packets and so on. The information is counted in packets.
Related command: reset udp statistics.

View
Interface view
Parameter
value: The maximum size of a TCP packet fragment, in the range from 128 to 2048.
Description
Use the tcp mss command to configure TCP packet fragmentation.
Use the undo tcp mss to remove TCP packet fragmentation.
Because the default MTU size is 1500 bytes, the sum of the encrypted packet header, overhead of link layer, IP header and the TCP packet should be less than 1500 bytes, so it is ideal to set the TCP packet fragment to 1200.
By default, TCP packets are not fragmented.
Example
# Set the maximum size of a TCP packet fragment to 300.
[XE-Ethernet1/0] tcp mss 300

Description
Use the tcp timer fin-timeout command to set the TCP finwait timer.
Use the undo tcp timer fin-timeout command to restore the TCP finwait timer to its default value.
By default, the TCP finwait timer is set to 675 seconds.
When the TCP connection status changes from FIN_WAIT_1 to FIN_WAIT_2, the finwait timer is started. If no FIN packet is received before finwait timer times out, the TCP connection will be terminated.
It is recommended that you configure this parameter under the guidance of technicians.

There are two mapping entries in the example above. Take the first entry as an example. It displays the IP address 192.168.80.30 and MAC address 00e0-fc20-2180, which is acquired through configuring static ARP.

Parameter
interface-type: Interface type.
interface-number: Interface number.
Description
Use the display ip interface command to display the current health of all interfaces.
Example
# Display the health of the interface Ethernet1/0.
<XE> display ip interface Ethernet1/0
Ethernet1/0 current state : UP
Line protocol current state : UP
Internet Address : 5.5.5.5/8
Broadcast address : 0.0.0.0
The Maximum Transmit Unit : 1500 bytes
input packets : 1231, bytes : 57557, multicasts : 1177
output packets : 0, bytes : 0, multicasts : 0

Parameter
hostname: Name of a host, a character string in the range from 1 to 20.
ip-address: IP address corresponding to the host name, can be class A,B,C or D.
Description
Use the ip host command to configure the entries of the static domain name resolution table, that is, the host names and their corresponding IP addresses.
Use the undo ip host command to remove the mapping between a host name and an IP address.
Each hostname can have only one corresponding IP address.
The hostname can be comprised of lower and upper letters a to z and A to Z, number 0 to 9, hyphen (-) and dot (.). Note that at least an English letter should be in the hostname.
By default, the static domain name table is empty, that is, there is no host name corresponding to any IP address.
Example
# Configure the IP address corresponding to the host name router1 to 10.110.0.1.
[XE] ip host router1 10.110.0.1
# Configure the IP address corresponding to the host name router2 to 10.110.0.2.
[XE] ip host router2 10.110.0.2
# Configure the IP address corresponding to the host name router3 to 10.110.0.3.
[XE] ip host router3 10.110.0.3
# Remove the mapping between the host name router2 and the IP address 10.110.0.2.
[XE] undo ip host router2 10.110.0.2

Parameter
static: Indicates to clear the static ARP entries.
dynamic: Indicates to clear the dynamic ARP entries.
all: Indicates to clear all the ARP entries.
interface: Indicates the selected interface.
interface-type: Interface type.
interface-number: Interface number.
Description
Use the reset arp command to clear the ARP entries in the ARP mapping table.
By default, if slot-number is not specified, all ARP entries are cleared.
When the operation is performed on the interface with specified interface, the interface type can only be Ethernet or virtual Ethernet, and only the dynamic entries of the interface can be deleted.
Related command: arp static, display arp.
Example
# Delete the dynamic entries in the ARP mapping table of the interface Ethernet1/0.
<XE> reset arp interface Ethernet1/0
