Disabling the Forwarding of IP Packets on an SRP Ethernet Interface

You can disable forwarding of packets on an switch route processor (SRP) Ethernet interface using the ip disable-forwarding command.

The purpose of this command is to maintain router performance by maximizing the CPU time available for routing protocols. Although you can allow data forwarding on the SRP Ethernet interface, router performance will be affected.

You see an error message if you try to set this command for interfaces other than the SRP Ethernet interface.

Before you configure IP, you must create the lower-layer interfaces over which IP traffic flows. All IP configurations will be removed from the interface when you issue the no ip interface command in Interface Configuration mode.

To disable forwarding of packets on the SRP Ethernet interface:

• Issue the ip disable-forwarding command in Interface Configuration mode.
  host1(config-if)#ip disable-forwarding

  Use the no version to enable forwarding of packets on the interface.
