Please tell me about the VPC specifications for Nexus switches.
We use two dedicated lines to connect two locations and make line redundancy by creating a vPC on two Nexus switches that accommodates the lines.
*This dedicated line allows the link status of one site to be communicated to the other site using link pass-through function.
This time, our line operator contacted us regarding changes to their equipment and asked us to change the accommodation port from auto-link to fixed-link.
It seems that we need to put the following command into each of the vPC pairs, Nexus01 and Nexus02.
SW# conf t
SW(config)# interface Po 20
SW(config-if)# speed 1000
SW(config-if)# duplex full
SW(config-if)# end
During the configuration process, auto-links and fixed-links will be mixed on the member ports of the vPC, but I am not sure if this is allowed, so I tried the above operation using a free port and found that it was not possible to configure it.
It turns out that it can be done.
However, since I tried it with a link-down port without a transceiver (Now, I don't have a spare transceiver on hand...), I'm not sure if it can actually be done with a link-up port or if it will affect communication.
I checked the documentation, but it's not clearly stated, so I'm worried.
If anyone knows how to use this, please let me know.
