All,
As has been discussed elsewhere, the 6500/7600 platforms lie about IPv6
packet/byte counters due to ASIC limitations (BTW I am told that this is
fixed in sup2T/PFC4/Earl8)
I think this alternative approach works for a limited set of cases:
class-map match-all QOS-ALL-IPV6
match protocol ipv6
class-map match-all QOS-ALL-IPV4
match protocol ip
policy-map QOS-COUNT-IPV6
class QOS-ALL-IPV4
set dscp default
class QOS-ALL-IPV6
set dscp default
int VlanA
service-policy input QOS-COUNT-IPV6
service-policy output QOS-COUNT-IPV6
int GiX/Y
switchport access vlan A
mls qos vlan based
mls qos statistics-export interval 30
mls qos statistics-export class-map QOS-ALL-IPV6
mls qos statistics-export class-map QOS-ALL-IPV4
mls qos statistics-export destination <some syslog params>
mls qos statistics-export
You can then parse the logs to get per-module counters for a given
class-map. This might be of use if you only have one or a few interfaces
to count, and have no existing, conflicting QoS needs.
Hope it's of use to someone.
Cheers,
Phil
