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
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 .
