Chapter 10 Configuring Ethernet OAM
Verifying CFM with EVC Default Encapsulation
To verify the configuration of CFM with EVC default encapsulation, use the show command shown
below.
Router# show running-config interface gigabitEthernet 0/9
Building configuration...
Step 4
service instance
instance-id
ethernet
evc-name
Example:
Router(config-if)# service instance 1 ethernet
evc100
Creates a service instance on an interface and defines the
matching criteria.
• instance-id—Integer that uniquely identifies a service
instance on an interface.
• evc-name—String that associates an EVC to the service
instance. Maximum byte size is 100.
Step 5
encapsulation default
Example:
Router(config-if-srv)# encapsulation default
Configures the default service instance.
Step 6
bridge-domain
bridge-id
Example:
Router(config-if-srv)# bridge-domain 99
Binds the service instance to a bridge domain instance using
an identifier.
Step 7
cfm encapsulation {dot1ad
vlan-id
| dot1q
vlan-id
} [dot1q
vlan-id
| second-dot1q
vlan-id
]
Example:
Router(config-if-srv)# cfm encapsulation dot1q
75
Configures connectivity fault management (CFM) Ethernet
frame encapsulation.
• dot1ad—Indicates the 802.1ad provider bridges
encapsulation type.
• dot1q—Supports the IEEE 802.1q standard for
encapsulation of traffic and specifies the outer dot1q
encapsulation tag.
• second-dot1q—Specifies the inner dot1q
encapsulation tag. Valid option only when you first
select the outer dot1q encapsulation tag. When the
dot1ad encapsulation type is selected first, dot1q is a
valid option.
• vlan-id—Integer from 1 to 4094 that specifies the
VLAN on which to send CFM frames.
Step 8
cfm mep domain
domain-id
mpid
mpid-value
Example:
Router(config-if-srv)# cfm mep domain md2 mpid
111
Configures a maintenance endpoint (MEP) for a domain.
• domain-name—String from 1 to 154 characters that
identifies the domain name.
• mpid—Indicates the maintenance point ID (MPID).
• mpid-value—Integer from 1 to 8191 that identifies the
MPID.
