I'm trying to use wccp (Web Cache Communication Protocol) on 3550 cisco switch, the problem is that I can't find wccp:

I can't do this command:

switch(config)#ip wccp ....


switch#sh ip wccp 

it seems that wccp is not defined, Why? and How can I define it?

I have seen a tutorial that tells:

In order to enable WCCP redirection in the Catalyst switch, you need to issue the sdm prefer extended-match command (and reboot the switch). By issuing the show sdm prefer command, you are able to see the actual configuration of the TCAM/ASIC Hardware in the switch.

so I did the following:

Switch(config)# sdm prefer routing extended-match
Switch(config)# exit
Switch# reload

but nothing worked!

    Short answer: it doesn't support WCCP. cisco.com/go/fn Look up the version of IOS running on your switch.

According to Feature Navigator you can use IOS image c3550-i5k2l2q3-mz.121-19.EA1.bin or c3550-i5q3l2-mz.121-19.EA1.bin for WCCPv2 on the 3550.

Cisco Feature Navigator - WCCPv2 / 3550

  • It wasn't showing anything last night. And it might be an EMI vs. SMI thing (which cannot be changed.)
