43.4.1.2 Configuring Performance Parameters
1. Setting the wait time for TCP connection
When the routing switch performs TCP connection, it considers that the TCP connection fails if the TCP
connection is not created during the wait time. The routing switch then notifies the upper-level program of the
failed TCP connection. You can set the wait time for TCP connection. The default value of the system is 75
seconds. The previous configuration has no impact on TCP connections that the switch forwards. It only
affects TCP connections that are created by the switch itself.
Run the following command in global configuration mode to set the wait time for TCP connections:
Run… To
ip tcp synwait-time seconds
Set the wait time for TCP connection.
2. Setting the size of TCP windows
The default size of TCP windows is 2000 byte. Run the following command in global configuration mode to
change the default window size:
Run… To
ip tcp window-sizebytes
Set the size of TCP windows.
43.4.1.3 Detecting and Maintaining IP Network
1. Clearing cache, list and database
You can clear all content in a cache, list or database. Incorrect data in a cache, list or database need be
cleared.
Run the following command to clear incorrect data:
Run… To
clear tcp statistics
Clear TCP statistics data.
2. Clearing TCP connection
To disconnect a TCP connection, run the following command:
Run… To
clear tcp {local host-name port
remote host-name port | tcb
address}
Clear the designated TCP connection.
TCB refers to TCP control block.
3. Displaying statistics data about system and network
The system can display the content in the cache, list and database. These statistics data can help you know
the usage of systematic sources and solve network problems.
Run the following commands in management mode. For details, refer to “IP Service Command”.
Run… To
show ip access-lists name
Display the content of one or all access
lists.
show ip cache [prefix mask] [type
Display the routing cache that is used for
