There shall be maximum throughput of 10Gbps for internal loopback over all the sessions. Simultaneous internal and external loopback on same interface is not supported. Re-write modifications on the loopback traffic is not supported. Restrictions for Ethernet Data Plane LoopbackĮthernet loopback on 元 interfaces or 元 sub interfaces is not supported.Įthernet loopback on PW-HE is not supported.įollowing filters for loopback are not supported:įollowing combinations of filter qualifiers are not supported for external loopbacks: The default time for auto removal of an EDPL session is 5 minutes, unless explicitly specified. Maximum number of concurrent ethernet data plane loopback sessions supported is 100. Source MAC, Destination MAC, and VLAN priority Supported filter qualifiersĪre Source MAC, Destination MAC, and VLAN priority(COS bits).įollowing are the supported combinations of filter qualifiers for external loopbacks: Multiple filters can be applied to ensure loop back of a subset of traffic received by an interface.
LOOPBACK MAC MAC
The MAC address on the looped-back traffic will always be swapped. In case of bundled interface, the traffic is looped back on all the bundle link members. The traffic loopback occurs after the trafficįlows into the router to the other interface.Įthernet loopback is supported on all the L2 transport interfaces (physical, bundle interfaces, and L2 sub-interfaces overīoth physical and bundle interfaces) on NCS4K-4H-OPW-QC2 line card. Terminal loopback (internal)-Traffic loopback occurs at the egress interface. The traffic does not flow into the router for This feature supports two types of ethernet loopback :įacility loopback (external)-Traffic loopback occurs at the ingress interface.
Throughput measurement, and on-demand/out-of-service (intrusive) operation during service turn-up. This feature allows both bidirectional and unidirectional User can verify the maximum rate of frame transmission with no frame loss.
The Ethernet Data Plane Loopback (EDPL) feature provides a means for remotely testing the throughput of an ethernet port.
This chapter describes the Cisco IOS XR commands to configure Ethernet Data Plane Loopback. Configure Ethernet Service Activation Test.
