Cisco ASR 9000 Series Configuration Guidelines

EFP IdentifierEncapsulation Type
A priority-tagged frame is defined as having a single
802.1Q VLAN header, with a VLAN id of zero.
Priority-tagged Ethernet frames
Cisco ASR 9000 Series Routers do not support native
VLAN.
Use this command:
encapsulation dot1q <vlan-id>, untagged
Native VLAN
802.1Q customer-tagged Ethernet framesSingle tagged frames
802.1Q (ethertype 0x8100) double tagged frames
802.1ad double tagged frames
Legacy 0x9100 and 0x9200 double tagged frames
Double tagged frames
An EFP which has a maximum-match wildcard. The
effect is to receive any traffic that does not match any
other EFP on the same physical interface.
Default tagging
You can use wildcards as well as VLAN ranges while defining frames that map to a given EFP. EFPs can
distinguish flows based on a single VLAN tag, a range of VLAN tags, a stack of VLAN tags or a combination
of both (VLAN stack with wildcards). It provides the EFP model, a flexibility of being encapsulation agnostic,
and allows it to be extensible as new tagging or tunneling schemes are added.
MAC Address Matching
The source MAC address, the destination MAC address, or both can be matched. In all cases, the MAC address
requires an exact match. A wildcard match or partial match is not adequate.
802.1p CoS Bits Matching
One or more exact CoS matches are specified. Because CoS is only 3 bits, this limits it to 8 possible choices.
Logical Conjunction
All of the match criteria above can be selectively combined those frames that match all of the separate criteria.
Default Match
A single EFP can be defined that matches all other traffic that has not been matched by a more specific EFP.
Match Precedence and Config Verification
Overlapping EFPs are allowed to be configured, where it is possible to determine an order in which they
should be used for matching. But EFPs that conflict with other EFPs or subinterfaces on the parent trunk
interface should be blocked at config verification.
An ordering precedence is used for how EFP matches are applied in hardware. The model is for matches that
are more specific to be processed before matches that are less specific.
