For details on fast switch description and limits, refer to Fast Switch in WAN performance configuration Directory

Ip fast-switch enable (global configuration mode)

Configure fast switch global mode

Ip fast-switch enable

no Ip fast-switch enable

parameter:

none

default:

no Ip fast-switch enable

command mode:

global configuration mode

explanation:

This command configures fast switch global mode

example:

router>enable

router#config

router_config#ip fast-switch enable

 

Ip fast-switch enable (interface configuration mode)

configure fast switch on the interface

Ip fast-switch enable

no Ip fast-switch enable

parameter:

none

default:

no Ip fast-switch enable

command mode:

interface configuration mode

explanation:

This command configures a port to be fast switch. After configuring fast switch in global mode, the command works.

example:

router>enable

router#config

router_config#interface f0/0

router_config_if#ip fast-switch enable

 

Show ip fast-switch stat

Display fast switch statistics

show ip fast-switch stat

parameter:

none

default:

none

command mode:

global configuration mode,interface configuration mode,supervisor mode

explanation:

Only after configuring fast switch, fast switch information will be displayed.

example:

router>enable

router#config

router_config#show ip fast-switch stat

Information will be displayed as follow:

    Ethernet1/1 configure fast switch

    encasulation ARP

    line protocol is up

    Total packets with protocol wrong 0

    Total packets with version or length wrong 0

    Total packets with TTL expiry 0

    Total packets forward successly 2378

    Total packets receive 4679

    Total packets with check sum error 0

    Serial 2/0 configure fast switch

    encasulation PPP

    line protocol is up

    Total packets with protocol wrong 0

    Total packets with version or length wrong 0

    Total packets with TTL expiry 0

    Total packets forward successly 2234

    Total packets receive 3789

Total packets with check sum error 0

 

The meaning of the statistic information is as follow:

Total packets with protocol wrong:means the number of the ip packets which protocol type is not equal 46.

Total packets with version or length wrong:means the number of the ip packets which version number is not V4 or the ip header lendth is not 20.

Total packets with TTL expiry:means the number of the ip packets which ttl value is less than 2

Total packets with check sum error:means the number of the ip packets in which there are CRC errors

Total packets forward successly:means the number of the ip packets which have been forworded successfully.

Total packets receive:means the total number of the received ip packets .
