Hello,
We have a pair of nexus 7K's (without vpc) running HSRP and MSTP.
They are connected to access layer switches 4948's. whenever we bring up a new
trunk link between Nexus 7K and 4948 we see unicast flooding caused due to
TCN's. I am wondering if it has something to do with the difference in cam
aging timer in both the platforms. Nexus (1800 secs) and 4948 (300 secs). can
anyone put some light here please? I am thinking that changing the aging timer
on nexus to 300 secs should help.. any thoughts?
