Release Information

Statement introduced in Junos OS Release 8.4.

Support for the switch-options statement added in Junos OS Release 9.2.

Support for top-level configuration for the virtual-switch type of routing instance added in Junos OS Release 9.2. In Junos OS Release 9.1 and earlier, the routing instances hierarchy supported this statement only for a VPLS instance or bridge domain configured within a virtual switch.

Statement introduced in Junos OS Release 9.5 for EX Series switches.

Support for logical systems added in Junos OS Release 9.6.

Statement introduced in Junos OS Release 11.1 for the QFX Series.

[edit switch-options], [edit switch-options interface interface-name], [edit vlans vlan-name switch-options], and [edit vlans vlan-name switch-options interface interface-name] hierarchy levels introduced in Junos OS Release 12.3 R2 for EX Series switches.

Support for EVPNs added in Junos OS Release 13.2 for MX 3D Series routers.

Hierarchy levels [edit switch-options interface interface-name] and [edit vlans vlan-name switch-options] introduced in Junos OS Release 13.2X50-D10 for EX Series switches.

Description

For QFX Series, EX Series switches and SRX Series devices, disables MAC address learning for the specified VLAN.

For QFX Series and EX4600, disable MAC address learning for the specified interface. Disabling MAC address learning on an interface disables learning for all the VLANs of which that interface is a member.

For EX Series switches’ Q-in-Q interfaces, disables MAC address learning for the specified interface. Disabling MAC address learning on an interface disables learning for all the VLANs of which that interface is a member.

For MX Series routers and EX Series switches with ELS support, disables MAC learning for a virtual switch, for a bridge domain or VLAN, for a specific logical interface in a bridge domain or VLAN, or for a set of bridge domains or VLANs associated with a Layer 2 trunk port. On platforms that support EVPNs, you can disable MAC learning on an EVPN.

Note

When MAC learning is disabled for a VPLS routing instance, traffic is not load-balanced and only one of the equal-cost next hops is used.

Default

MAC learning is enabled.
