A9K-RSP5-SE MANAGEMENT PORT

[PK99]

Ever since we got this unit in our lab (admittedly we never paid attention) but only 1 Management port shows up on 

show ip int brief

That port works fine when connected but when the other port is connected, nothing - (pretty obvious since Mgmt1 is not even showing up on show ip int brief

Do we need to RMA this?

This is normal, we have this in our lab as well

So is MGMT ETH 1 not a functional interface?  It doesn't show up on sh ip int brief, but when I connect a cable to it, it lights up.  It even allows me to go into 

RP/0/RSP0/CPU0:ios(config)#interface mgmtEth 0/rsp0/cpu0/1
RP/0/RSP0/CPU0:ios(config-if)#no shut
RP/0/RSP0/CPU0:ios(config-if)#

It accepts this but when I try to actually find it, it's not anywhere.

have you checked the admin plane?

admin

show interface

The link Tarun provided explains this, in x64-bit because we have different VMs between xr and admin(sysadmin) there is a need for a mgmt port for each VM. So Mgmt port 0 is still used for the regular xr vm and mgmt port 1 is used in sysadmin. This is expected behavior you are seeing.

Look normal?

Yes, that is how it is supposed to look.
