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 rot7507-3(config-cmap)#match access-group name ABC_12 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".
