Statement introduced before Junos OS Release 7.4.
Statement introduced in Junos OS Release 9.0 for EX Series switches.
Support for Layer 2 VPNs and VPLS introduced in Junos OS Release 10.4.
Statement introduced in Junos OS Release 12.1X48 for PTX Series Packet Transport
Routers.
Statement introduced in Junos OS Release 12.2 for ACX Series Universal Access Routers.
Support at the
[set interfaces interface-name unit logical-unit-number family ccc]
level introduced in Junos OS Release 12.3R3 for MX Series routers.
Specify the maximum transmission unit (MTU) size for the media or protocol. The default
MTU size depends on the device type. Changing the media MTU or protocol MTU causes
an interface to be deleted and added again.
To route jumbo data packets on an integrated routing and bridging (IRB) interface or
routed VLAN interface (RVI) on EX Series switches, you must configure the jumbo MTU
size on the member physical interfaces of the VLAN that you have associated with the
IRB interface or RVI, as well as on the IRB interface or RVI itself (the interface named irb
or vlan, respectively).
CAUTION: For EX Series switches, setting or deleting the jumbo MTU size on
an IRB interface or RVI while the switch is transmitting packets might cause
packets to be dropped.
