Parameters
default: Matches all traffic that does not match any other Ethernet service instance on the interface. On
an interface, you can configure this criterion only in one Ethernet service instance.
tagged: Matches all frames that have an 802.1Q VLAN tag.
untagged: Matches all frames that do not have an 802.1Q VLAN tag.
s-vid vlan-id: Matches frames that are tagged with the specified outer VLAN ID. The vlan-id argument
specifies a VLAN ID in the range of 1 to 4094. If the outer VLAN is not the PVID, the matching result
does not differ, whether or not you specify the only-tagged keyword. If the outer VLAN is the PVID, the
matching result depends on whether or not the only-tagged keyword is specified.
only-tagged: Matches only PVID-tagged frames. To match both untagged frames and PVID-tagged
frames, do not specify this keyword.
NOTE:
The outer VLAN refers to the C-VLAN for a single-tagged frame and the S-VLAN for a double-tagged
frame.
Usage guidelines
The match criteria in each Ethernet service instance on an interface must be unique. For example, you
cannot configure the encapsulation tagged command in one Ethernet service instance if another
Ethernet service instance already contains this command. The VLAN ID specified with the encapsulation
s-vid vlan-id command cannot be the same for any two Ethernet service instances on the interface.
An Ethernet service instance can contain only one matching criterion. To change the match criterion,
you must remove the original criterion first. When you remove the match criterion in an Ethernet service
instance, the association between the service instance and the VSI is removed automatically. For an
Ethernet service instance to match frames from a VLAN on an interface, you must first create the VLAN
and assign the interface to the VLAN.
If an Ethernet service instance contains the encapsulation default match criterion, traffic is matched as
follows:
The service instance matches all frames if it is the only instance on the interface.
•
The service instance matches frames that do not match any other service if it is not the only instance
•
on the interface.
Examples
# Configure service instance 1 on FortyGigE 1/0/1 to match packets that have an outer VLAN ID of
111.
