x450-g2 stack port transceiver info

Dustin_Willis — Tue, 25 Jun 2024 18:46:02 GMT

Is it possible to view the transceiver information (DDMI) for the stack ports on x450-g2? Easy enough on normal SFPs.

I have one switch (out of 7) that is losing stack links pretty regularly on one or both ports. It also happens to take a different physical route through a couple of fiber patch locations that were done by a 3rd party unfamiliar to me, but at first glance, it's not all-star caliber splicing. Hoping to see how it looks on tx/rx power levels without being forced to visit the site with an OTDR. Thanks.

Hi Dustin,

Since these ports are not normally accessible/configurable, you don't see their DDMI output in 'show port transceiver info detail'.

However, you should be able to get this information via the following non-service-impacting debug command:

debug hal show optic-info ddmi

The native stacking ports will be the highest number port reported (which won't exist in 'show port'). I believe the only other switch with a similar native stacking port scenario is the x465.

Hope that helps!
