Release Information Statement introduced in Junos OS Release 9.2.
Statement introduced in Junos OS Release 13.2X50-D10 for EX Series switches.
Statement introduced in Junos OS Release 13.2 for the QFX Series.
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 Getting Started with Enhanced Layer 2
Software.
(QFX Series 3500 and 3600 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.
Required Privilege
