Hi Guys,
I have a physical fault on a 5596UP mgmt0. Pair 4 is unterminated so will only come up at 100Mb/s instead of 1Gb/s. All cabling has been tested and the Cat6509 port it connects to has been swapped. I take it that the entire 5596 will need replacing and that the management interface can't be replaced on its own? I use this interface as the vPC keep-alive - will there be any issues running at 100Mb/s, even under fault conditions, as I don't want to RMA if I can help it?
Thanks

Hi,
There is no issue with mgmt running at 100Mps. That link is just for keep-alive messages and nothing else.
That is just fine.
from vPC design document:
vPC peer-keepalive link—The peer-keepalive link monitors the vitality of a vPC peer Cisco Nexus 5000 Series device. The peer-keepalive link sends configurable, periodic keepalive messages between vPC peer devices. No data or synchronization traffic moves over the vPC peer-keepalive link; the only traffic on this link is a message that indicates that the originating switch is operating and running vPCs.

Thanks Reza, that's what I was hoping.
