Nexus 5672 vPC convergence time becomes SO LONG

Please help me.

The more I make vlans, the longer vPC's convergence-time becomes.

I did make almost 4000 vlans and convergence time is around 6sec.

The test traffic is only "vlan 11" and 1000 frames/sec.

However, when I erase vlans and only 2 vlans exist, it beomes around 200msec.

Does anyone know why and tell me how to survive it!

 

vlan 1, 11-3967
no spanning-tree vlan 1-3967, 4048-4093

What do you do with that many

What do you do with that many VLANs?
You do know that it will add to processing time

Also kindy check "show processors cpu" check the levels
That a lot of VLANs
