R211x-HP Flexfabric 11900 MPLS Command Reference

17
mpls mtu
Use mpls mtu to configure the MPLS MTU for an interface.
Use undo mpls mtu to restore the default.
Syntax
mpls mtu value
undo mpls mtu
Default
The MPLS MTU of an interface is not configured. Fragmentation for MPLS packets is based on the MTU
of the interface, and the length of a fragment does not include that of the MPLS label. Thus, after an MPLS
label is added into a fragment, the length of the MPLS fragment might exceed the interface MTU.
Views
Interface view
Predefined user roles
network-admin
mdc-admin
Parameters
value: Specifies the MPLS MTU of the interface, in the range of 46 to 65535 bytes.
Usage guidelines
This command is effective only when MPLS is enabled on the interface.
If the MPLS MTU is larger than the interface MTU, data forwarding might fail.
MPLS TE tunnel interfaces do not support this command.
Examples
# Set the MPLS MTU of interface VLAN-interface 2 to 1000 bytes.
<Sysname> system-view
[Sysname] interface vlan-interface 2
[Sysname-Vlan-interface2] mpls enable
[Sysname-Vlan-interface2] mpls mtu 1000
