Is it okay to use different service group numbers?

A new deployment of vWAAS in a DC connected to a Cat 6509 with existing WCCP redierection from an old WAAS deployment on that switch using service groups 61 and 62. I have researched service group numbers but only find a handful and want to ask the community if there are any issues using service groups 51 and 52, or 71 and 72 for this new deployment.

Thanks, Karl

Hi Karl,

Service groups 61 and 62 are tcp promiscous groups and will redirect all TCP traffic. Also, in case of the wccp web-cache , this is going to redirect all the traffic from TCP port 80 from routers to Cisco Cache/ACNS devices. Other Custom WCCP services c will use custom wccp number (90 - 97) . So if you want to redirect port 8080 you can use custom WCCP service group.

Some of the well known service groups are listed below and you can use which ever you want according to your requirement.

Hi Kanwal, Let me ask my question in a different way as you provided all the information that I was already able to find. What other service numbers can I use that are TCP promicuous and will redeirect all traffic exactly like 61 and 62?

Hi Karl,

I don't think so. These are pre-defined. So you will need to use 61 and 62 for TCP Promiscous. If you need to redirect any other ports you can use CUSTOM service group.

Hi Kanwal,

I thought I would follow up as I did more research and found that you can use any of the other unassigned numbers for the service group. In this case 71/72 and it works just fine.

Best, Karl
