After you run the display mpls interface verbose command, the following information is displayed:
<HUAWEI>display mpls interface vlanif 100 verbose
No                    :  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.
