4k questions


I have two 4k connected to each other with a single mode fiber, gigabit. This is a mesh link. Both runs the C.09.19 firmware and has about 20 VLANs on them. I use this configuration to bring all my 20 subnets to my desk. Something like a mux/demux. My question is: why is one of them having a constant ~70% cpu utilization while the other one is at ~25%?

Also, when I prioritize VLAN id 1 (used to manage these switches), I get ping losses when pinging the switch. Telnetting & http'ing to the switch also becomes flaky.

If a problem can be fixed, there's nothing to worry. If a problem can't be fixed, worrying ain't gonna help. Bottom line: don't worry.
