Nexus 5010 with 1G and 10G uplinks in VPC

[rchilcote]

I currenty have a Nexus 5010 connected to a core 3750X switch stack  in a VPC trunk using 2  1Gbps links.  I want to move this link to 2  10Gbps links without losing connectivity.  So I want remove a 1G link  and move it to 10G and then once that's up move the other 1G link to 10G  hopefully without losing connectivity.  So the question is, can I have a  1G and 10G link between the Nexus and 3750s in the same virtual port  channel without causing problems?

Thanks in advance.

Unfortunately, that is not possible since you can not have an Etherchannel with one 1Gig link and one 10Gig link.  The speed and duplex of all links in an Etherchannel must be the same.  You would need a outage window to remove the Gig links and add the 10Gig link.

Thanks for the help.

You don't necessarily need an outage. Remove one link from the port channel, add it to a new vpc/port channel.

Let it stabilize, either spt or routing depending on the type of channel, then move the 2nd link.
