Ethernet Performance Monitoring on Untagged EFPs

The Ethernet Performance Monitoring on untagged EFPs feature enables sessions to run on untagged Ethernet flow points (EFPs).

Untagged EFPs

The Ethernet Performance Monitoring on untagged EFPs feature enables sessions to run on untagged Ethernet flow points (EFPs). If an EFP is configured as untagged, then the EFP handles any frames without a dot1q tag, that it receives. Any frames sent using this EFP do not have a dot1q tag.

The dot1q tag contains class of service (CoS) bits, which are used by EPM to test delay or loss of packets with a specific CoS. This support is unavailable when using EPM over untagged EFPs but all other performance monitoring functionality is supported.

Configuring Ethernet Performance Monitoring on Untagged EFPs

SUMMARY STEPS

  1. enable
  2. configure terminal
  3. interface type/number
  4. service instance ID ethernetevc-id
  5. encapsulation untagged
  6. end
  7. configure terminal
  8. ip sla operation-number
  9. ethernet y1731 {delay | loss} type domain domain-name {evc evc-id | vlan vlan-id} {mpid target-mp-id | mac-address target-address} cos cos-value {source {mpid source-mp-id | mac-address tsource-address }}
  10. exit
  11. ip sla schedule operation-number start-time time life life
  12. end

DETAILED STEPS

  Command or Action Purpose
Step 1

enable

Example:


Device> enable

Enables privileged EXEC mode.

  • Enter your password if prompted.

Step 2

configure terminal

Example:


Device# configure terminal

Enters global configuration mode.

Step 3

interface type/number

Example:


Device(config)# interface GigabitEthernet0/0

Configures an interface and enters interface configuration mode.

Step 4

service instance ID ethernetevc-id

Example:


Device(config-if)# service instance 1 ethernet 50

Configures a service instance and enters service instance configuration mode.

Step 5

encapsulation untagged

Example:


Device(config-if-srv)# encapsulation untagged

Sets the encapsulation as untagged.

Step 6

end

Example:


Device(config-if-srv)# end

Returns to privileged EXEC mode.

Step 7

configure terminal

Example:


Device# configure terminal

Enters global configuration mode.

Step 8

ip sla operation-number

Example:


Device(config)# ip sla 501

Configures a Cisco IOS IP Service Level Agreements (SLAs) operation and enter IP SLA configuration mode.

Step 9

ethernet y1731 {delay | loss} type domain domain-name {evc evc-id | vlan vlan-id} {mpid target-mp-id | mac-address target-address} cos cos-value {source {mpid source-mp-id | mac-address tsource-address }}

Example:


Device (config-ip-sla)# ethernet y1731 delay DMM domain domain1 evc evc1 mpid 101 cos 0 source mpid 100
Begins configuring the receiver on the responder and enters IP SLA Y.1731 delay configuration mode.

  • The source-mp-id or source-address configured by this command corresponds to that of the MEP being configured.

Note 

The type argument in the above command syntax takes the following values: DMM, SLM.

Step 10

exit

Example:


Device (config-ip-sla)# exit

Exits IP SLA configuration mode and returns to privileged EXEC mode.

Step 11

ip sla schedule operation-number start-time time life life

Example:


Device(config-sla-y1731-delay)# ip sla schedule 501 start-time now life forever

Begins a probe with a specified operation number starting at the specified timestamp (or ‘now’ for immediately) for the specified lifetime in seconds (or ‘forever’ to run until the configuration is removed).

Step 12

end

Example:


Device(config-sla-y1731-delay)# end

Returns to privileged EXEC mode.
