Command Purpose
ip route-cache hardware-index ticks
The bigger the ticks, the faster the SWITCH can add the
hardware route cache.
To set the lifetime of the hardware route cache, run the following command in global mode:
Command Purpose
ip route-cache-aging-time seconds
Sets the lifetime of the SWITCH hardware route cache.
To enable the route cache add to the hardware table, run the following command in the global configuration
mode:
Command Purpose
ip route-cache cache-pbr
Adds the route cache which searches the route by the
route policy to the hardware table.
(8) Supporting IP Fast Exchange on the Same Interface
You can enable the SWITCH to support IP fast exchange by making the receiving interface the same as the
transmitting interface. Generally, it is recommended not to enable the function because it conflicts with the
redirection function of the router.
Run the following command in the VLAN interface configuration mode to allow IP routing cache in the same
interface:
Command Purpose
ip route-cache same-interface
Allows IP message with the same receiving/transmitting
interfaces to be stored in the routing cache.
53.1.2 Configuring Performance Parameters
Run the following command to adjust IP performance.
(1) Setting the Wait Time for TCP Connection
When the SWITCH triggers the TCP connection and if the TCP connection is not established in the designated
wait time, the SWITCH views that the connection fails and then sends the result to the upper-layer program.
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:
