Hey there,

These specific state up/down messages are layer 1; think signal on the wire. I would check the cables, patch paneling, etc. Also, are the optics supported or third party?

@ben_beck

hi there

thanks for answering my question.

the cable is fine, already to check on the other device, the topology is port 1/20, 1/21, 1/23 connect to other switch non icx 1/2,1/3,1/5 via copper sfp. and on the oppenent switch the port is normal, no updown like on ICX log.

what does mean ?

thank for your help

The message seen is layer 1 related, so this would generally be optic, media, patch-panel, etc.

Is this a ruckus-supported optic?

show media validation

show media eth x/y/z

Have you used these optics elsewhere on ICX switches without issue?

So did you create a LAG with those 3 ports and do you have loop protect and or Spanning-Tree enabled, and do you have a trunk/channel-group or LAG created on the other switch for aggregating these three ports and is loop protect and or Spanning-tree enabled on the other switch? Or do you have separate vlans on each link between the switches?

@tim_brumbaugh

Thanks For the answers

yes we have separate vlans on each link between the switches, 12 vlans on 3 port. the port whitout LAG config, just trunk. If we enable STP on each vlan on that 3 port, STP should be disable the port. that's mean there are indication loop ?

I would recommend opening a support case (see my signature) so we can properly investigate this issue.

Why did you put the vlans on separate ports verse creating a LAG? It would simplify any spanning-tree or loop protect issues especially if someone were to make a mistake adding vlan and it a port was to go down it would not affect the link being up but amount of traffic it was capable of would drop. Either way I would check to see if they are supported Ruckus transceivers as mentioned above by Ben and get the info on them.

show media validation

show media eth x/y/z

We have had issues with some Cisco and HP transceivers not working correctly and of course they are not covered by support. What is the other switch you are trying to connect to?
