3750 Route map counters

[aweise]

Hi all,

We're running a simple policy map on a 3750 stack (IOS version 12.2(53)SE2), but the route-map counters do not show any matches:

NYKIRDRCX01#sh route-map

route-map remote-route, permit, sequence 51

  Match clauses:

    ip address (access-lists): remoteACL

  Set clauses:

    ip next-hop 192.168.101.5

  Policy routing matches: 0 packets, 0 bytes

However, I've confirmed via our netflow monitor that the traffic we're trying to send to the appropriate next hop is, indeed, getting there correctly.

I've seen issues in the past with a 3750 not reporting counters correctly, so I'm wondering if there is still a bug in this IOS version. Anyone know?

Those are software counters and PBR is done in hardware. Under that platform, the only way to verify PBR is working is by testing with traffic towards the next-hop.

Edison is absolutely correct.

These counters are not incremented due to the fact that PBR was performed in hardware. A true test of traffic forwarding is the only way to tell for sure.
