MAC Learning

Support to learn the MAC-IP information of the host (QFX5120 switches)—You can use MAC-IP snooping for non-EVPN VLANs to learn the MAC-IP information of the host. Use the new command global-mac-ip-snooping in the [edit protocols l2-learning] hierarchy to enable this feature. The show ethernet-switching mac-ip-table command output displays the MAC IP information. You can verify whether MAC-IP snooping is enabled for a VLAN by using the show vlans extensive command. You can disable the feature for a VLAN by using the new command no-mac-ip-snooping in the [edit vlans <vlan-name> switch-options] hierarchy.
