Cisco ASR 901 Series Aggregation Services Router Software Configuration Guide
OL-23826-09
Chapter 10 Configuring Ethernet OAM
Examples
This example shows how to configure CFM over EVC using cross connect.
ASR901(config)#ethernet cfm ieee
ASR901(config)#ethernet cfm global
ASR901(config)#ethernet cfm domain L5 level 5
ASR901(config-ecfm)# service s1 evc e711
ASR901(config-ecfm-srv)# continuity-check
ASR901(config-ecfm-srv)#exit
ASR901(config-ecfm)#exit
Example for untagged Encapsulation
ASR901(config)#int g0/1
ASR901(config-if)#service instance 711 ethernet e711
Step 7
service instance id ethernet [ser-
vice-name]
Example:
Router(config-if-srv)# service in-
stance 101 ethernet
Creates a service instance (an instantiation of an EVC)
on an interface and sets the device into the config-if-srv
submode.
Step 8
encapsulation untagged | dot1q vlan-id
| default
Example:
Router(config-if-srv)# encapsulation
dot1q 100
Configures the encapsulation. Defines the matching
criteria that maps the ingress dot1q or untagged frames
on an interface for the appropriate service instance.
Effective with Cisco IOS Release 15.3(2)S, default
encapsulation is supported.
Note dot1q range and second-dot1q are not supported
for EFP Interface with Cross Connect.
Step 9
xconnect peer-ip-address vc-id {encap-
sulation {l2tpv3 [manual] | mpls [man-
ual]} | pw-class pw-class-name
}[pw-class pw-class-name] [sequencing
{transmit | receive | both}]
Example:
Router(config-if-srv)# xconnect
10.0.3.201 123 pw-class vlan-xconnect
Binds an attachment circuit to a pseudowire, and
configures an Any Transport over MPLS (AToM) static
pseudowire.
Step 10
cfm mep domain domain-name [up | down]
mpid mpid-value [cos cos-value]
Example:
Router(config-if-srv)# cfm mep down
mpid 100 domain Core
Configures a maintenance endpoint (MEP) for a domain.
Step 11
exit
Example:
Router(config-if-srv)# exit
Exits the interface configuration mode.
