Cisco ASR 920 series Configuration Guide Ethernet Router

Description
Double-tagged 802.1Q encapsulation. Matching criteria to be used to map QinQ
frames ingress on an interface to the appropriate EFP. The outer tag is unique
and the inner tag can be a single VLAN, a range of VLANs or lists of VLANs
or VLAN ranges.
•
Enter a single VLAN ID in each instance for an exact match of the
outermost two tags.
•
Enter a VLAN range for second-dot1q for an exact outermost tag and a
ranged second tag.

Ethertype encapsulation is the payload encapsulation type after VLAN
encapsulation.
• ethertype—The etype string can have these values: ipv4, ipv6,
pppoe-discovery, pppoe-session, or pppoe-all.
•
Matches any or an exact outermost VLAN or VLAN range and a payload
ethertype.

CoS value encapsulation defines match criterion after including the CoS for the
S-Tag and the C-Tag. The CoS value is a single digit between 1 and 7 for S-Tag
and C-Tag.
You cannot configure CoS encapsulation with encapsulation untagged, but
you can configure it with encapsulation priority-tag.
The result is an exact outermost VLAN and CoS match and second tag. You can
also use VLAN ranges.

Adds one or more VLAN tag values for matching criteria. This command is also
used with show run command when the encapsulation configuration command
is more than the terminal width and ethernet service multi-line command is
configured or if the encapsulation command is more than 255 characters.
