How to configure backplane interfaces on SVC-CMM-6T1 module and SUP32?
I have a hard time to understand the theory to configure the backplane interfaces on CMM-6T1 and SUP32. Here is the picture looks like:
- Sup32 is in slot 5 of 6509
- CMM-6T1 is in slot 1 of the same 6509
- Saw the output when show cdp nei on sup32:
G1/0 (sup) <--> G1/1 (CMM)
F1/5 (Sup) <--> F3/0 (CMM)
- When I configured all those four interfaces as layer3 interfaces, they can ping each other from either CMM or SUP.
- However, according to the link below, it is required to confiugred interfaces on sup as layer2 (switch acccess vlan). I did, CMM and SUP can not ping each other (I put G1/0 and F3/0 on CMM in the same vlan as interface vlan on Sup)
Re: How to configure backplane interfaces on SVC-CMM-6T1 module
I saw the 'compatibility' issue mentioned in the linked document. However, I configured all those 4 backplane interfaces as layer3 interfaces (which is assigned the IP addresses to them), so that SUP32 and CMM-6T1 module can talk to each other over layer3. The result is everything is working fine so far. GW on the CMM has no problem to run MGCP backhaul with Callmanager, and any-to-any ping is working....
So I am really in doubt of this 'compatibility' issue. Cisco is verifying on this.
