Those two ports are in a lag on both Powerconnects AND the Meraki switch. I have not tried unplugging just the Cat6, my testing phases were unplugging power to one of the switches. A little drastic I know, but it worked for the 8024Ks so I figured I'd give it a shot. I am trying to simulate loosing an entire 7048 switch, not just the port.
But that should have been my first troubleshooting step. I will try this and get back to you. From what your seeing though, my configs look good and I should be able to loose one of the two switches? The management IP should move over to the secondary switch and I should still be able to access once the primary goes down, correct?
Hi Daniel. I finally was able to test this tonight.
When I unplug either port 1/0/48 or 2/0/42 redundancy works. I keep the uplink with no issues, other than a dropped ping or two.
When I unplug one of the 2 switches (either one) I looks access to the switches and I can no longer ping the management IP of the switch., 10.0.0.160. Do I need to maybe configure an IP on both switches? OR is it just one for the stack?
Thanks Daniel, I will give that a try during our next maintenance window. How long should I expect it to take for the switch to redirect traffic one one is unplugged?
Just tried this on my 7048s and I believe the commands are actually
console(config)[tag:stack]
console(config-stack)#nsf
And to give credit where credit's due I do believe this post has helped with a long standing issue I've noticed on my switches. Very surprised that NSF isn't enabled by default.
