Configuring Local MAC Swap Loopback

Configuring Local MAC Swap Loopback

Pre-configuration Tasks

A local MAC swap loopback test checks Ethernet connectivity and network performance.

Before configuring local MAC swap loopback, complete the following tasks:

  • Create a VLAN and add the interface where you want to perform the remote MAC swap loopback test to the VLAN.

  • Configure QoS CAR if you want to test QoS on the network (see Traffic Policing, Traffic Shaping, and Interface-based Rate Limiting in the S1720, S2700, S5700, and S6720 V200R010C00 Configuration Guide - QoS).

    The MAC swap loopback test cannot be used with the ACL (including the ACL used in CAR, traffic statistics, and 802.1p priority re-marking) that matches the source and destination MAC addresses of loopback test packets.
