I recently duplicated a non-redundant 3BXL setup with a pair of units
running HSRP+RSTP. Everything appears to work great, except for almost
100Mbps / 20kpps of flooding. I took a span of the traffic and it's
straight up random unicast traffic on all the busy VLANs. Tried setting
the global mac aging on both to 14400 with little to no observed change.
Other than the flooding, there doesn't seem to be any routing/switching
issues.
The copp policy, and traffic/mac table sizes are pretty much identical
to the non-HSRP setup from before that didn't have any issues.
CPU usage is quite low.
Could this be a copp problem or something else I'm overlooking with
HSRP?
