Extreme Summit stack randomly decided to give all unlabeled ports a generic display string?

Extreme Summit stack randomly decided to give all unlabeled ports a generic display string?

Hey everyone,

I'm seeing some odd behavior on a handful of my switch stacks. This behavior has only occurred on stacks where a failed node has been replaced. Stacks that have never had a failed node do not display this behavior. That may totally be a red herring, but I wanted to point it out.

The behavior we are seeing is that all ports that did not previously have a display-string configured are now configured with a simple (and useless) name of "switchSNMPname_portnumber". We only have two network engineers with access to our CLI, and neither of us would have (intentionally) done something quite this dumb.

For example, here is the expected output from a good configuration:

Slot-1 MDF.1 # sh vlan eng

Ports: 117. (Number of active ports=88)
Untag: *1:1, *1:2, *1:3, *1:9, *1:10, *1:11, *1:12,
*1:17, *1:18, *1:19, *1:20, *1:26, *1:28, *1:33,
*1:34, *1:35, *1:36, *1:41, *1:42, 1:43, *1:44,
*1:47, *2:10, *2:12, 2:13, 2:15, 2:16, *2:17,
*2:18, *2:20, *2:21, *2:23, *2:26, 2:28, 2:29,

And here is the output from a stack showing the behavior in question:

Slot-1 IDF01.2 # sh vlan eng

Ports: 20. (Number of active ports=7)
Untag: *1:5(IDF01_1:5),1:6(IDF01_1:6),*1:9(IDF01_1:9),*1:10(IDF01_1:10),*1:13(IDF01_1:13),1:14(IDF01_1:14),1:20(IDF01_1:20),
1:21(IDF01_1:21),1:22(IDF01_1:22),1:30(IDF01_1:30),2:21(IDF01_2:21),2:22(IDF01_2:22),4:14(IDF01_4:14),4:28(IDF01_4:28),
4:29(IDF01_4:29),*4:30(IDF01_4:30),6:5(IDF01_6:5),*6:37(IDF01_6:37)
Tag: *1:53bg, *6:53g

As you can see, this makes it super annoying to look at things in the CLI, and we have no idea why it happened. I can go through and manually unconfigure the display strings (and have been) but we are just generally curious what caused this in the first place.

Thanks for any insight!

What version of code are you on? How are the nodes being replaced? Do you have a NMS pushing information to the switch?

I feel like this was a bug in NetSight. I know I encountered something similar and had to go through and delete the labels. It was annoying and I am trying to remember how I kept it from reoccurring if this is the same issue I encountered it was not a random occurrence but an unexpected result of something you did in NetSight.
