Hello everyone,

Today I will share with you what MTUs indicate in the display mpls interface verbose command output.

After you run the display mpls interface verbose command, the following information is displayed:

<HUAWEI>display mpls interface vlanif 100 verboseNo                    :  1
Interface             :  Vlanif100
Status                :  Up
TE Attribute          :  Disable
Static LSPCount       :  0
Static CR-LSPCount    :  0
LDP LSPCount          :  0
RSVP LSPCount         :  0
MPLS MTU              :  -
Interface MTU         :  1500
Effective MTU         :  1500
TE FRR                :  Disable
Interface Index       :  0xd1

MTUs in the preceding command output indicate different meanings:

  • MPLS MTU: MTU configured using the mpls mtu command.

  • Interface MTU: MTU negotiated on the interface.

  • Effective MTU: Smaller MTU between MPLS MTU and Interface MTU.

When the MPLS MTU or Interface MTU changes, the configuration takes effect only after you restart the interface.

That is all I want to share with you! Thank you!
