I have strange issue with HP ProCurve J8692A 3500yl-24G. If I display MACs on port I see it:

3500(config)# sh mac 10 | inc 5cf3fc-a53456

But if I try to find where is this MAC then I have no luck:

(config)# sh mac 5cf3fc-a53456
 Status and Counters - Address Table - 5cf3fc-a53456 
MAC address 5cf3fc-a53456 not found.

Any ideas where can be the problem?

Edited: I test another MAC:

3500# sh mac 003048-33d8f6

 Status and Counters - Address Table - 003048-33d8f6

MAC address 003048-33d8f6 not found.
3500# sh mac | inc 003048-33d8f6
  003048-33d8f6 5

so this not looks as MAC, config mode or port issue. Also:

MAC addr count#                1241       1257       1248       1449       1391
                     Low          *          *       1229       1222       1219
                    High          *          *       1266       1897       1897

and this switch have much larger (AFAIR 64k) MAC address table size, so it not looks like full MAC address table issue.

PS. It run on bit old K.14.41 software. I check Release notes for K.14 series, but I don't see similar problem resolved in any next release.

  • Well the OID suggests its an IBM device. The documentation suggests you are supposed to see the port number that this address is learned on. While I doubt this can be a switch system address, perhaps including the entire output of the sho mac 10, also just for grins try the commands not in config mode – fredpbaker Oct 11 '13 at 22:13
  • @fredpbaker I edited post and added more information. I not post full output of sh mac 10 because it's rather long - I have another switch on this port :) – dsznajder Oct 12 '13 at 8:10
  • So what I see is that a normal mac address entry as a port number in it per the doc. The IBM address does not. The sho mac <address> command seems to never work. This smells like code defects – fredpbaker Oct 12 '13 at 17:07

    @fredpbaker, the IBM address doesn't show a port number because that is a "sh mac <interface> | inc <MAC>" whereas the second is from a "show mac | inc <MAC>". Since the first includes the interface with the input, there is no reason to include it in the output. – YLearn Oct 14 '13 at 21:48

You need to upgrade to the K.15 series. I also have a 3500yl-48G, and prior to K.15 I definitely saw bugs.

sh mac-a never worked properly for me in K.14, but does in K.15.

    This is a borderline "+1" comment, but I want to reinforce robbat2's comment about K.14.* K.14.* was really buggy in a lot of ways. You will certainly do yourself numerous favors by getting off of it and go ahead and getting up to K.15.* Not that K.15.* is perfect by any means, but its tremendously better. – Jeff McAdams Dec 10 '13 at 14:35
