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?

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?

no issues these optic use on other icx
