Configuring Ethernet
CFM and Y.1731 Performance Monitoring on Layer 3 Interfaces
This chapter provides procedures for configuring the network interface device functionality, Ethernet data plane loopback, IEEE connectivity fault management, and Y.1731 performance monitoring.
For configuring EVC Bridge Domain (BD) and the features it supports, see Configuring Ethernet Virtual Connection Bridge Domain.
This chapter contains the following sections:
- Configuring a Network Interface Device on the L3 Interface
- Ethernet Data Plane Loopback
- CFM Support on Routed Port and Port MEP
- Support for Y.1731 Performance Monitoring on Routed Port (L3 Subinterface)
Configuring a Network Interface Device on the L3 Interface
Configuring a Network Interface Device (NID) enables support for the NID functionality on the router without including a NID hardware in the network. This feature combines the Customer-Premises Equipment (CPE) and the NID functionality into a physical device. The following are the advantages of configuring the NID functionality:
- Eliminates a physical device.
- Supports both the managed CPE feature set and the NID requirements.
 Note | This feature is supported only if you have purchased the advipservices licensing module. For more information about managing software activation licenses on the Cisco ISR and Cisco ISR G2 platforms, see http://www.cisco.com/en/US/docs/routers/access/sw_activation/SA_on_ISR.html . |

Verifying the NID Configuration
Use the following commands to verify the port tagging sessions:
- show run int
- ping
Use the show run int command to display the port tagging sessions:
Router#show run int gi0/2 Building configuration... Current configuration : 10585 bytes ! interface GigabitEthernet0/2 no ip address duplex auto speed auto port-tagging encapsulation dot1q 10 set cos 6 exit end ! interface GigabitEthernet0/2.1101 encapsulation dot1Q 100 ip address 132.1.101.4 255.255.255.0 ! interface GigabitEthernet0/2.1102 encapsulation dot1Q 100 ip address 132.1.102.4 255.255.255.0 !
Use the ping command to verify the connectivity with port tagging configured:
Router#ping 132.1.101.3 Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 132.1.101.3, timeout is 2 seconds: !!!!! Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/4 ms router#
Troubleshooting the NID Configuration
Table 1 lists the debug commands to troubleshoot the issues pertaining to the NID functionality.
The Cisco IOS Master Command List at
http://www.cisco.com/en/US/docs/ios/mcl/allreleasemcl/all_book.html http://www.cisco.com/en/US/docs/ios/mcl/allreleasemcl/all_book.html provides more information about these commands.
 Caution | Because debugging output is assigned high priority in the CPU process, it can diminish the performance of the router or even render it unusable. For this reason, use debug commands only to troubleshoot specific problems or during troubleshooting sessions with Cisco technical support staff. |
Note | Before you run any of the debug commands listed in the following table, ensure that you run the logging buffered debugging command, and then turn off console debug logging using the no logging console command. |

Enables debugging of packet processing (VLAN tag pop) on the ingress side. |
Ethernet Data Plane Loopback
The Ethernet Data Plane Loopback feature provides a means for remotely testing the throughput of an Ethernet port. You can verify the maximum rate of frame transmission with no frame loss.
Note | This feature is supported only if you have purchased the advipservices licensing module. For more information about managing software activation licenses on the Cisco ISR and Cisco ISR G2 platforms, see http://www.cisco.com/en/US/docs/routers/access/sw_activation/SA_on_ISR.html . |
Note | Internal Ethernet data plane loopback is not supported. |

Restrictions for Configuring Ethernet Data Plane Loopback
Follow the guidelines and take note of the restrictions listed here when configuring Ethernet data plane loopback on a Layer 3 interface:
- Only external loopback (packets coming from the wire side) on the L3 dot1q subinterface and (untagged) main interface are supported.
- To perform a MAC swap, the destination address and source address must be swapped for the packets that are looped back. If the destination address is broadcast or multicast, the MAC address is used as the source address for the packets that are looped back.
- Loopback operations are supported at line rate.
- Untagged frames are not supported on a subinterface. However, the frames for dot1q and qinq are supported on a subinterface.
- dot1ad is not supported on the main interface. However, untagged frames are supported on the main interface.
- Single VLAN is supported as a filtering option for a subinterface, but VLAN list and VLAN range are not supported.
- Only MAC address is supported as a filtering option for the main interface.
- For the filtering option, the destination MAC cannot be combined with inner VLAN or outer VLAN.
- There is no support for L3 and L4 loopback. Source and destination IP address or source and destination ports will not be swapped.
- Connectivity Fault Management (CFM) packets are transparent to the data plane loopback configuration and cannot be looped back.
- Packets coming from the other side of the wire where loopback is configured and having the same destination MAC address are dropped.
- The broadcast and multicast IP addresses of the broadcast and multicast IP frames that are received cannot be used as the source IP address of the frame when it is sent back to the initiator. In such a case, the IP address of the subinterface is used as the source IP address of the frame when it is sent back to the initiator.
Configuring External Ethernet Data Plane Loopback
Configuring external Ethernet data plane loopback is permitted on a Layer 3 main interface and subinterfaces.
The following steps show how to configure external Ethernet data plane loopback on a subinterface using single and double tagging. (The procedure to configure external Ethernet data plane loopback on the main interface is similar to this procedure.)
- encapsulation dot1q vlan-id
- encapsulation dot1q vlan-id second-dot1q inner vlan-id

DETAILED STEPS
Configuration Examples for Ethernet Data Plane Loopback
This example shows how to configure Ethernet data plane loopback using single tagging:
Router>enable Router#configure terminal Router(config)#interface gigabitethernet 0/2.1101 Router(config-subif)#encapsulation dot1q 100 Router(config-subif)#ethernet loopback permit external Router(config-subif)#end
This example shows how to configure Ethernet data plane loopback using double tagging:
Router>enable Router#configure terminal Router(config)#interface gigabitethernet 0/2.1101 Router(config-subif)#encapsulation dot1q 100 second-dot1q 1101 Router(config-subif)#ethernet loopback permit external Router(config-subif)#end
This example shows how to start an Ethernet data plane loopback:
Router#ethernet loopback start local interface gigabitethernet 0/2.1101 external timeout none This is an intrusive loopback and the packets matched with the service will not be able to pass through. Continue? (yes/[no]): Enter yes to continue.
This example shows how to stop an Ethernet data plane loopback:
Router#ethernet loopback stop local interface gigabitethernet 0/2.1101 id 1 Router#*Oct 21 10:16:17.887: %E_DLB-6-DATAPLANE_LOOPBACK_STOP: Ethernet Dataplane Loopback Stop on interface GigabitEthernet0/2 with session id 1 Router#show ethernet loopback active Total Active Session(s): 0 Total Internal Session(s): 0 Total External Session(s): 0
Verifying the Ethernet Data Plane Loopback Configuration
Use the following commands to verify the Ethernet data plane loopback configuration:
- show ethernet loopback permitted
- show ethernet loopback active
Use the show ethernet loopback permitted command to view the loopback capabilities per interface:
Router#show ethernet loopback permitted -------------------------------------------------------------------------------- Interface SrvcInst Direction Dot1q/Dot1ad(s) Second-Dot1q(s) -------------------------------------------------------------------------------- Gi0/2.1101 N/A External 100 1101
Use the show ethernet loopback active command to display the summary of the active loopback sessions on a subinterface:
Router#show ethernet loopback active Loopback Session ID : 1 Interface : GigabitEthernet0/2.1101 Service Instance : N/A Direction : External Time out(sec) : none Status : on Start time : *10:17:46.930 UTC Mon Oct 21 2013 Time left : N/A Dot1q/Dot1ad(s) : 100 Second-dot1q(s) : 1101 Source Mac Address : Any Destination Mac Address : Any Ether Type : Any Class of service : Any Llc-oui : Any Total Active Session(s): 1 Total Internal Session(s): 0 Total External Session(s): 1

Support for Y.1731 Performance Monitoring on Routed Port (L3 Subinterface)
Y.1731 Performance Monitoring (PM) provides a standard Ethernet PM function that includes measurement of Ethernet frame delay, frame delay variation, frame loss, and frame throughput measurements specified by the ITU-T Y-1731 standard and interpreted by the Metro Ethernet Forum (MEF) standards group.
Note | This feature is supported only if you have purchased the advipservices licensing module. For more information about managing software activation licenses on the Cisco ISR and Cisco ISR G2 platforms, see http://www.cisco.com/en/US/docs/routers/access/sw_activation/SA_on_ISR.html . |

Frame Delay
Ethernet frame delay measurement is used to measure frame delay and frame delay variations. Ethernet frame delay is measured using the Delay Measurement Message (DMM) method.
Restrictions for Configuring Two-Way Delay Measurement
Follow the guidelines and restrictions listed here when you configure two-way delay measurement:
- Y.1731 PM measurement works only for a point-to-point network topology.
- The granularity of the clock for delay measurement is in seconds and nanoseconds.
- CFM Y.1731 packets work with a maximum of two VLAN tags. The expected behavior is not observed with more VLAN tags. Also, CFM Y.1731 packets do not work with untagged cases.
Configuring Two-Way Delay Measurement
The following steps show how to configure two-way delay measurement. Both single and double tagging methods are included in the steps listed below.
- ethernet y1731 delay DMM domain value vlan vlan-id mpid value cos value source mpid value
- ethernet y1731 delay DMM domain value vlan vlan-id inner-vlan inner vlan-id mpid value cos value source mpid value

DETAILED STEPS
Configuration Examples for Two-Way Delay Measurement
This example shows how to configure two-way delay measurement using single tagging:
router>enable router#configure terminal router(config)#ip sla 1101 router(config-ip-sla)#ethernet y1731 delay DMM domain customer vlan 100 mpid 3101 cos 1 router(config-sla-y1731-delay)#aggregate interval 30 router(config-sla-y1731-delay)#exit router(config)#ip sla schedule 1102 life forever start-time now router(config)#end
This example shows how to configure two-way delay measurement using double tagging:
router>enable router#configure terminal router(config)#ip sla 1101 router(config-ip-sla)#ethernet y1731 delay DMM domain customer vlan 100 inner-vlan 1101 mpid 3101 cos 1 source mpid 4101 router(config-sla-y1731-delay)#aggregate interval 30 router(config-sla-y1731-delay)#exit router(config)#ip sla schedule 1101 life forever start-time now router(config)#end
Verifying Two-Way Delay Measurement Configuration
Use the following commands to verify the performance-monitoring sessions:
- show run | sec ip sla
- show ip sla summary
- show ip sla statistics entry-number
- show ip sla configuration entry-number
- show ethernet cfm pm session summary
- show ethernet cfm pm session detail session-id
- show ethernet cfm pm session db session-id
The following are the sample outputs of the commands listed above:
Router#show run | sec ip sla
ip sla auto discovery
