WAAS Configuration for 3750 Switch

I am configuring a 3750 switch with 12.2(52)SE according to:

(from https://www.cisco.com/en/US/docs/switches/lan/catalyst3750/software/release/12.2_52_se/configuration/guide/3750_scg.pdf )

This example shows how to configure SVIs and how to enable the web cache service with a multicast group list. VLAN 299 is created and configured with an IP address of 175.20.20.10. Gigabit Ethernet port 1 is connected through the Internet to the web server and is configured as an access port in VLAN 299. VLAN 300 is created and configured with an IP address of 172.20.10.30. Gigabit Ethernet port 2 is connected to the application engine and is configured as an access port in VLAN 300. VLAN 301 is created and configured with an IP address of 175.20.30.50. Fast Ethernet ports 3 to 6, which are connected to the clients, are configured as access ports in VLAN 301. The switch redirects packets received from the client interfaces to the application engine.

Note Only permit ACL entries are being used in the redirect-list; deny entries are unsupported.

Question:  How do I configure my WAE to play nicely with this switch?

WAAS Configuration for 3750 Switch

Hi James,

Here is the link to WCCP config part on WAE:

http://www.cisco.com/en/US/docs/app_ntwk_services/waas/waas/v441/configuration/guide/traffic.html#wp1041742

In your case, if my understanding is right, VLAN300 is where you want to connect WAE and WAE is also L2 adjacent. if that is true, here is the config you need on WAE:

wccp router-list 1 171.69.198.100

wccp tcp-promiscuous router-list-num 1 l2-redirect mask-assign l2-return

wccp version 2

Please note that 3750 supports L2 redirection only with redirect IN statements on 3750 interfaces connected to servers and clients.

Hope this helps.

Regards.
