[c-nsp] Apply C-VID and S-VID to untagged packet

[Aaron]

Sorry for the bad formatting....

It seems that maybe you could encap untagged, then on ingress, push 2 tags,
then NOT use the symmetric command thus I believe it wouldn't push those 2
aforementioned tags in the opposite (egress direction) but only apply 2 tags
(c and s as you described) in the input direction

Maybe like this.

RP/0/RSP0/CPU0:9k(config)#int GigabitEthernet0/0/0/9.15 l2transport

RP/0/RSP0/CPU0:9k(config-subif)#encapsulation untagged

RP/0/RSP0/CPU0:9k(config-subif)#rewrite ?
  ingress  Set the tag rewriting policy for this EFP

RP/0/RSP0/CPU0:9k(config-subif)#rewrite ingress ?
  tag  Set the tag rewriting policy for this EFP

RP/0/RSP0/CPU0:9k(config-subif)#rewrite ingress tag ?
  pop        Remove one or more tags
  push       Push one or more tags
  translate  Replace tags with other tags

RP/0/RSP0/CPU0:9k(config-subif)#rewrite ingress tag translate ?
  1-to-1  Replace the outermost tag with another tag
  1-to-2  Replace the outermost tag with two tags
  2-to-1  Replace the outermost two tags with one tag
  2-to-2  Replace the outermost two tags with two other tags


RP/0/RSP0/CPU0:9k(config-subif)#rewrite ingress tag push ?
  dot1ad  Push a Dot1ad tag
  dot1q   Push a Dot1Q tag


RP/0/RSP0/CPU0:9k(config-subif)#rewrite ingress tag push dot1q ?
  <1-4094>  VLAN Id to push


RP/0/RSP0/CPU0:9k(config-subif)#rewrite ingress tag push dot1q 111 ?
  second-dot1q  Push another Dot1Q tag
  symmetric     All rewrites must be symmetric


RP/0/RSP0/CPU0:9k(config-subif)#rewrite ingress tag push dot1q 111
second-dot1q ?
  <1-4094>  VLAN Id to push


RP/0/RSP0/CPU0:9k(config-subif)#rewrite ingress tag push dot1q 111
second-dot1q 222 ?
  symmetric  All rewrites must be symmetric


RP/0/RSP0/CPU0:9k(config-subif)#rewrite ingress tag push dot1q 111
second-dot1q 222 symmetric ?
  <cr>


RP/0/RSP0/CPU0:9k(config-subif)#rewrite ingress tag push dot1q 111
second-dot1q 222 symmetric

Does anyone know of a way to do this without using 2 switches?  I've used
selective q-in-q to apply an outer 802.1Q tag to a given C-VID, as well as a
number of other options on a selective q-in-q port, but can't seem to handle
untagged packets the way I want to do it, i.e. applying an inner and outer
tag to the packet.  Using the native vlan doesn't work, or at least I
haven't managed to get it working that way.

Thank you,
