Configuring Flow Parameters

The CSS enables you to configure the following flow parameters using the flow

command:

• flow permanent - Permanent TCP ports that are not reclaimed

• flow port-reset - Resets Fast Ethernet and Gigabit Ethernet ports

automatically when the CSS detects that they are not responding

• flow reserve-clean - Interval flows with port numbers less than or equal to 23

are reclaimed

Configuring Permanent Connections for TCP Ports

The CSS allows you to configure a maximum of ten TCP ports that will have

permanent connections and will not be reclaimed by the CSS when the ports are

inactive. To configure a TCP port as a permanent connection, use the flow

permanent command. This command is typically used when load-balancing

long-lived connections or you observe the CSS dropping long-lived idle TCP

connections.

The options for this command are:

• flow permanent port1 portnumber

• flow permanent port2 portnumber

• flow permanent port3 portnumber

• flow permanent port4 portnumber

• flow permanent port5 portnumber

• flow permanent port6 portnumber

• flow permanent port7 portnumber

• flow permanent port8 portnumber

• flow permanent port9 portnumber

• flow permanent port10 portnumber

Enter a port number from 0 to 65535. The default is 0.
