A question for those of you running colorless ports. Are you really trunking to every switch every possible vlan that a user or device can authenticate to?
That’s a ton of unnecessary L2 traffic even if using high bandwidth uplinks. Not to mention the higher exposure to a broadcast storm with all that ARP traffic flying around.
I’ve seen Juniper ex3400s kneel over at 3K MAC addresses even though they advertise a table that can handle 32K. At what table size does performance become affected?
