Description

TUNNEL/4/TUNN_PS_PTOW: OID [OID] switched to work tunnel. (IfIndex=[INTEGER], WorkTunnel=[OCTET], WorkTunnelId=[INTEGER], ProtectionTunnel=[OCTET], ProtectionTunnelId=[INTEGER], SwitchResult=[INTEGER], WorkTunnelState=[INTEGER], ProtTunnelState=[INTEGER], LocalState=[INTEGER])

The protection group switched from the protection tunnel back to the work tunnel.

Parameters

Name Meaning

OID

Indicates the MIB object ID of the alarm.

IfIndex

Indicates the index value of the work tunnel.

WorkTunnel

Indicates the name the work tunnel.

WorkTunnelId

Indicates the tunnel ID of the work tunnel.

ProtectionTunnel

Indicates the name of the protection tunnel.

ProtectionTunnelId

Indicates the tunnel ID of the protection tunnel.

SwitchResult

Indicates the result of the switchover. The value 1 indicates that the tunnel becomes the work tunnel.

WorkTunnelState

Indicates the status of the work tunnel.

ProtTunnelState

Indicates the status of the protection tunnel.

LocalState

Indicates the status of local node.

Impact on the System

Services will not be affected.

Possible Causes

The work tunnel returned to the normal state and the protection tunnel switched to the work tunnel.

Procedure

  1. Run the display mpls te protection tunnel all verbose command to check the work-tunnel name field to obtain the name of the work tunnel.
  2. Run the display interface tunnel interface-number command to check the status of the work tunnel.

    • If the status of the work tunnel is Up, it indicates that the trap message is informational only, and no action is required.
    • If the status of the work tunnel is Down, it indicates that faults occur on both the protection and work tunnels. Do as follows on both the protection and work tunnels:

  3. Run the display this interface command in the tunnel interface view to check whether the route destined for the destination exists.

    • If so, go to Step 4.
    • If not, configure the route destined for the destination. After that, if the fault disappears, go to Step 10; if the fault persists, go to Step 4.

  4. Run the display this command in the tunnel interface view to check whether the destination address of the tunnel, tunnel type, and tunnel ID are correctly configured, and whether the mpls te commit command is configured.

    • If so, go to Step 5.
    • If not, modify the configurations. After that, if the fault disappears, go to Step 10; if the fault persists, go to Step 5.

  5. Run the display this command in the tunnel view to check whether the mpls te path explicit-path path-name command is configured, that is, whether the explicit path is configured.

    • If so, go to Step 6.
    • If not or only parts of the explicit path are configured, go to Step 9.

  6. Run the display explicit-path path-name command to check the IP address of each hop on the explicit path.
  7. Run the display ip interface interface-type interface-number command to check whether the interface at each hop is Up.

    • If all interfaces are Up, go to Step 8.
    • If an interface is Down, check whether the interface is configured with the shutdown command. If so, run the undo shutdown command. After that, if the fault disappears, go to Step 10; if the fault persists, go to Step 8.

  8. Run the display this command on each interface on the tunnel to check whether MPLS, MPLS TE, and RSVP-TE are enabled.

    • If so, go to Step 9.
    • If a function is disabled, enable it. After that, if the fault disappears, go to Step 10; if the fault persists, go to Step 9.

  9. Collect alarm information and configuration information, and then contact technical support personnel.
  10. End.
