I'm trying to enable just one SFP+ port for testing a 10gbit NIC. I cannot, however, for the life of me find how to enable a port. To me, it would make sense to

  1. conf t
  2. interfaces TenGigE0/0/2/0 admin up ( or something like this) I know this isn't right, but it is where my brain is currently.

Everything I can find just says to use "no shutdown" then reload the config. Completely new to cisco stuff and I'm becoming frustrated.

Reset to default

troz-gw-1#conf t
Enter configuration commands, one per line.  End with CNTL/Z.
troz-gw-1(config)#interface TenGigE0/0/2/0
troz-gw-1(config-if)#no shut
troz-gw-1(config-if)#exit
troz-gw-1(config)#exit
troz-gw-1#wr mem

That's what is meant by "no shut". (of course, there's a ton more configuration to make an interface fully operational -- addresses, etc.)

    IOS XR will have a few more steps, depending on the context from which you start.
