Hi WCCP experts,
Two questions please.
According to
IP Application Services Configuration Guide, Cisco IOS XE Release 3S (Cisco ASR 1000).
• The following limitation applies to WCCP Layer 2 Forwarding and Return feature:
Layer 2 redirection requires that content engines be directly connected to an interface on each WCCP router.
Q1. Will it work if there is a L2 switch between the WCCP router and conte engines?
Right now we have the WCCP ASR1002 router connected to a L2 switch trunk port. One of the sub-interfaces will be used for the connection to content engines.
. For content engines running Application and Content Networking System (ACNS) software, use the wccp
custom-web-cache command with the l2-redirect keyword to configure L2 redirection. For content
engines running Cisco Wide Area Application Services (WAAS) software, use the wccp tcp-promiscuous
command with the l2-redirect keyword to configure L2 redirection.
Q2. I have Blue Coat as content engines. What configuration commands ASR1002 should have for L2 redirection?
Thanks
Cedar

Hi Cedar,
If i am not wrong the directly connected actually means that ASR and CE or in your case Blue coat proxy should be in the same subnet. If they are in the same subnet then of course you can use switch in between.

Have a look at the link above and look at L2 redirection and return.
Wccp customer-web-cache etc are all services and you can use any one or custom numbers as your network requirment. You can use 90 or web-cache which is for port 80 or 61, 62 etc.
You can see the list of well known service groups.
