Campus Manager - bpdufilter/bpduguard and portfast

Hi,

I have problem with my Campus Manager installation. The Physical Discrepancy Report show these messages:

Port Fast Enabled on Trunk Port

BPDU-Guard disabled on access ports

BDPU Filter disabled on access ports

But my swicthes are OK. It seems that CM ignore the default configuration:

spanning-tree portfast default

spanning-tree portfast bpduguard default

spanning-tree portfast bpdufilter default

Do you have any idea ?

ps: My Campus version version is 4.0.10. The swicthes are 2950 with IOS 12.1(22)EA11.

Thanks

Re: Campus Manager - bpdufilter/bpduguard and portfast

There was a bug that would account for the two BPDU discrepancies, but that was fixed in CM 4.0.8. A new Campus Data Collection after upgrading to 4.0.8 or higher should have removed those discrepancies. Therefore, it would be helpful to see the running-config from this switch as well as the complete discrepancy details.

Hi,

Here is the configuration of one of my 2950. I erase some line (password, etc) but the most important is there.

I am posting the Physical Discrepancy Details Report. I hope this can help.

Please provide an SNMP Walk starting at c2900PortSpantreeFastStart (.1.3.6.1.4.1.9.9.87.1.4.1.1.36) from this switch.

Hi,

This is the snmp walk that you asked for. I think that the swicth 2950 is sending wrong values.

Re: Campus Manager - bpdufilter/bpduguard and portfast

It sure looks like the switch says you have portfast enabled on Gi0/1 and Gi0/2. Please post a walk of the whole c2900PortTable and a walk of ifDescr.

OK.

Re: Campus Manager - bpdufilter/bpduguard and portfast

It looks like a bug when spanning-tree portfast default is enabled. Any port which does not have any explicit portfast configuration is listed as disabled in the C2900-MIB. If a port has spanning tree disabled explicitly, then the MIB reflects its status as enabled.

You can test this by removing the two spanning-tree portfast disabled commands under your trunk ports. After another Campus Data Collection, the discrepancies about portfast being enabled on trunk ports should disappear.

I understand. Thanks for your help.
