Description
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.
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.
