wccp with wsa

[clark white]

Dears,

i have 2 no's of  wsa i am planning to have redundancy, if incase  one of the wsa fails still the 6509 will forwards traffic to fails wsa ???

I want to know what does actually layer 4 switch does ??

below is the configuration

access-list 10 permit host 10.1.1.1-----WSA-1

 access-list 10 permit host 10.1.1.2---WSA--2

ip access-list extended protocols

permit tcp any any eq 443

permit tcp any any eq 20

permit tcp any any eq 21

permit tcp any any eq 80

ip wccp version 2
ip wccp 120 redirect-list protocol

ip wccp web-cache group-list 10

interface gigabitethernet2/1

description wsa-1
ip wccp 120 redirect in

interface gigabitethernet2/2

description wsa-2

ip wccp 120 redirect in

Thanks

If you have 2 WSAs, set up using WCCP, and one fails so that WCCP detects that its down, all traffic WILL get routed to the other WSA.

A "Layer 4" switch is a way of saying "policy based routing".  Its a non-Cisco way of getting traffic to a WSA.

Dear Ken,

thanks for your precious time you spend on the post,

Is it the WCCP configuration on 6509 is perfect for 2 no's of WSA.

which cisco product is a layer 4 switch, i need more explanation can you route me to any configuration example.

[Ken Stieers]

don't worry about "layer 4", it doesn't affect you...

I think you have the config wrong.

I have some questions first...

Is the firewall plugged into the 6509? If so, which port(s)?

Which firewall do you have?  Is it redundant?

Dear Ken,

My boss is asking me so i have to explain him layer 4 traffic monitoring

the configs posted are for 6509, P1 interface connected to core 6509 and P2 to ASA DMZ interface, firewall inside interface is connected to core.

firewall is redundant.

Try google...

I would put the WCCP on the ASA, not the 6509... see the attached doc.

Dear Ken

If i am connecting to switch 6509 then also it is a best practice from cisco ??

Can you confirm me the WCCP configs on the 6509.

thanks
