attaching ipv6 access-list to class-map unsupported ?

Answered Question
Jun 15th, 2008

on router Cisco 7507 IOS 12.2(25)S5

I created an IPv6 access-list already on router called ABC_12.

and When I try to get these commands on router:

rot7507-3(config)#class-map CG_1_name

rot7507-3(config-cmap)#match access-group name ABC_1 <!-- Works -->

rot7507-3(config-cmap)#match access-group name ABC_12 <!- error -->

IPV6 access list is not supported in match commands

and when I try other way around i.e. define class-map followed by

Access-list, it gives

"ACL "ABC_1" is currently attached to classmap, please remove the ACL

from classmap".

I have this problem too.

ABC_1 is still attached to the class map right?

i think u misunderstood my question, let me re-frame

Initially i created ipv6 accesslist say ABC_12,

then i tried to attach to class-map it failed with error sayin "unsupported"

and wen i tried creating class-map followed by ACL, it gave different error..

> All i wanna know is whether IPv6 acls are supported with class-maps on the router/IOS version i specified.

Thanks in advance..

It should be fine to use IPv6-ACl on the class-map command.Just try to upgrade your cisco IOS.Let's check what features you are looking for here. :

Note: I didn't see your IOS when I used these keywords

- IPv6 QoS: (Quality of Service)

- IPv6 QoS: MQC Packet Classification
