[c-nsp] Mac address flapping..

[James Ashton]

Alan,
 The 3548 is not part of the VTP.  And I am not passing it a trunk.  Just the one vlan.


and the 6509s do handle the VLANs.   But there are no tweeks to HSRP.  Just the default settings like all the others.

Hi,

are they in the same VTP domain or having trunks fed to them?
those switches are very very old and weak in terms of numbers
of VLANs - especially in PVST mode etc

do you handle the VLANs on the 6506 devices (ie they are the routers?)
if so, have you checked the settings for VLAN 42 - esp. with regard to
HRSRP?
