display mpls stale-interface

Function

The display mpls stale-interface command displays information about MPLS interfaces in the Stale state.

Format

display mpls stale-interface [ interface-index ] [ verbose ]

Parameters

Parameter	Description	Value
interface-index	Specifies the index of a specified stale interface.	The value is a hexadecimal integer ranging from 1 to FFFFFFFE.
verbose	Displays detailed information about an interface, for example, whether FRR is configured. If FRR is configured, information about the bound tunnels is also displayed.	-

Views

All views

Default Level

1: Monitoring level

Usage Guidelines

The outbound interface of the primary tunnel protected by TE FRR becomes a stale interface in one of the following situations:

MPLS is disabled on the interface when the primary tunnel is in the FRR In-used state.

The display mpls stale-interface command displays information about the stale interfaces.

Run the display mpls stale-interface command without specifying a parameter to view the index of a stale interface.

Example

# Display information about all MPLS interfaces in the Stale state.

<HUAWEI> display mpls stale-interface
Stale-Interface       Status    TE Attr   LSP Count  CRLSP Count Effective MTU
0x81a                 Up        Dis       0          1           1500

**Table 1** Description of the display mpls stale-interface command output
Item	Description
Stale-Interface	Index of an MPLS interface in the Stale state.
Status	Status of the stale interface. Up Down
TE Attr	Whether MPLS TE is enabled on an interface: Dis: MPLS TE is not enabled on the interface. En: MPLS TE is enabled on the interface.
LSP Count	Number of LSPs on an interface.
CRLSP Count	Number of CR-LSPs on an interface.
Effective MTU	MTU value used in the MPLS forwarding. If the MPLS MTU is not set, the interface MTU takes effect. If the MPLS MTU is set, the smaller one between the MPLS MTU and the interface MTU takes effect.

**Table 2** Description of the display mpls stale-interface verbose command output
Item	Description
No	Serial number.
Interface	Index of an MPLS interface in the Stale state.
Status	Status of the stale interface, which is the Up state in this example.
TE Attribute	Whether MPLS TE is enabled on the interface: Disable: MPLS TE is disabled. Enable: MPLS TE is enabled.
Static LSPCount	Number of static LSPs created on the interface.
Static CR-LSPCount	Number of static CR-LSPs created on the interface.
LDP LSPCount	Number of LDP LSPs created on the interface.
RSVP LSPCount	Number of RSVP-TE LSPs created on the interface.
MPLS MTU	MPLS MTU set using the mpls mtu command. When the interface is in the Stale state, a hyphen (-) is displayed.
Interface MTU	MTU configured on the interface. To set the MTU, run the mtu command.
Effective MTU	MTU value used in the MPLS forwarding. If the MPLS MTU is not set, the interface MTU takes effect. If the MPLS MTU is set, the smaller one between the MPLS MTU and the interface MTU takes effect.
TE FRR	Whether MPLS TE is enabled on the interface: Disable: No bypass tunnel is set up in manual FRR mode to protect the interface. Enable: A bypass tunnel is set up in manual FRR mode to protect the interface.
Manual Bypass	Name of a bypass tunnel set up in manual FRR mode.
Interface State	Interface status. Stale indicates that the interface is to be deleted.
