[PdhineshK]

Hi Team,

Recently we have purchased the GLC-TE SFP from the Cisco team.We tried to connect those SFP's not working in our Cisco nexus switch but the same we have few old GLC-TE SFP tested on the same port its working so no issue in the switch port side.

Below are the output we are getting for the new SFPs switch running on IOS 5.0(3).

Need your valuable inputs on this to fix this issue.

Hello,

I don't see the GLC-TE, in the attached compatibility matrix (Table 3), only the GLC-T...

Cisco Nexus 3000 Series

GLC-TE is supported on Nexus-3064 from software version NX-OS 6.0(2)U3(1). Cisco Transceiver Modules Compatibility Information has frequent updates.

Hello,

check if your Nexus supports the command:

NEXUS3064(config)# service unsupported-transceiver

[PdhineshK]

Let me chk this command.

What is the purpose of this command and what would be the impact if we apply this command??

[Georg Pauwen]

The command allows for transceivers that are not recognized to be...recognized; it works sometimes, but I am not sure it is supported on the Nexus at all....

[PdhineshK]

I have tried to apply the below command but not accepting let me know how to fix this issue.



NEXUS3064(config)# service unsupported-transceiver
