vPC Speed in UCSM

[Tom MacDonald]

We currently have 2 10G FC connections going into each FI and a pair of Nexus 5K's (a total of 4 10G connections). This consists of our vPC and it is displaying an operational speed of 10G, should this not be 20G?

Hello Mike,

UCSM version ?

Can you please share the screen shot on where you notice the operational speed ?

Also, share the output of following command

connect nxos

show int port-channel

I would think the operational speed would be similar to our FC-port-channel trunk (32G with 4 FC connections).....

UCSM 2.1......

The following bug is fixed in 2.1.1a for the operational speed value displayed in GUI for ethernet port-channels.

I just checked the lab device running 2.1.1a and it still shows 10 Gbps as operational speed value for upstream LAN port-channel

.

I would suggest you to open a TAC service request to further investigate this issue.
