Description

Note:

This statement supports the Enhanced Layer 2 Software (ELS) configuration style. If your switch runs software that does not support ELS, see port-mode. For ELS details, see Using the Enhanced Layer 2 Software CLI.

QFX3500 and QFX3600 standalone switches—Determine whether the logical interface accepts or discards packets based on VLAN tags. Specify the trunk option to accept packets with a VLAN ID that matches the list of VLAN IDs specified in the vlan-id or vlan-id-list statement, then forward the packet within the bridge domain or VLAN configured with the matching VLAN ID. Specify the access option to accept packets with no VLAN ID, then forward the packet within the bridge domain or VLAN configured with the VLAN ID that matches the VLAN ID specified in the vlan-id statement.

Note:

On MX Series routers, if you want IGMP snooping to be functional for a bridge domain, then you should not configure interface-mode and irb for that bridge. Such a configuration commit succeeds, but IGMP snooping is not functional, and a message informing the same is displayed. For more information, see Configuring a Trunk Interface on a Bridge Network.

Options

access—Configure a logical interface to accept untagged packets. Specify the VLAN to which this interface belongs using the vlan-id statement.

trunk—Configure a single logical interface to accept packets tagged with any VLAN ID specified with the vlan-id or vlan-id-list statement.

trunk inter-switch-link—For a private VLAN, configure the InterSwitch Link protocol (ISL) on a trunk port of the primary VLAN in order to connect the switches composing the PVLAN to each other. You do not need to configure an ISL when a PVLAN is configured on a single switch. This configuration specifies whether the particular interface assumes the role of interswitch link for the PVLAN domains of which it is a member. This option is supported only on MX240, MX480, and MX960 routers in enhanced LAN mode.

Required Privilege Level

interface—To view this statement in the configuration.

interface-control—To add this statement to the configuration.

Release Information

Statement introduced in Junos OS Release 9.2.

inter-switch-link option introduced in Junos OS Release 14.2 for MX240, MX480, and MX960 routers in enhanced LAN mode.
