display mpls interface
mpls mtu
Use mpls mtu to specify the MPLS MTU of 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. In this case, MPLS packets will be fragmented based on
the MTU of the interface, and the length of a fragment will not include that of the MPLS label. Thus, after
an MPLS label is inserted into a fragment, the length of the MPLS fragment may be larger than the
interface MTU.
Views
Interface view
Default command level
2: System level
Parameters
value: Specifies the MPLS MTU of the interface, in the range of 46 to 65535.
Usage guidelines
The 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.
The command does not apply to TE tunnel interfaces.
Examples
# Configure the MPLS MTU of interface GigabitEthernet 2/1/1 as 1000.
<Sysname> system-view
[Sysname] mpls
[Sysname-mpls] quit
[Sysname] interface gigabitethernet 2/1/1
[Sysname-GigabitEthernet2/1/1] mpls
[Sysname-GigabitEthernet2/1/1] mpls mtu 1000
mpls statistics enable
Use mpls statistics enable to enable MPLS statistics for an interface, LSP, or public network tunnel.
Use undo mpls statistics enable to disable MPLS statistics.
Syntax
mpls statistics enable { interface interface-type interface-number | lsp in-label in-label | tunnel token
token }
