Field

 

Description

 

 

 

TO

 

Timeout: Indicates by an “*” if entry is being timed out in forwarding.

 

 

 

Mac/Encaps

 

Length in bytes of Layer 2 header, and length in bytes of packet

 

 

encapsulation, including Layer 2 header and label header.

 

 

 

MTU

 

Maximum transmission unit (MTU) of labeled packet.

 

 

 

Label Stack

 

All the outgoing labels on the forwarded packet.

 

 

Packets Switched

Number of packets switched with this incoming label.

 

 

Label switching

Number of Label switching (LFIB) forwarding entries.

 

 

IPv4 label imposition

Number of IPv4 label imposition forwarding entries (installed at ingress

 

 

LSR).

 

 

MPLS TE tunnel head

Number of forwarding entries (installed at ingress LSR) on MPLS TE

 

 

tunnel head.

 

 

MPLS TE fast-reroute

Number of forwarding entries (installed at PLR) for MPLS

 

 

traffic-engineering (TE) fast reroute.

 

 

Forwarding updates

Number of forwarding updates sent from LSD (RP/DRP) to LFIB/MPLS

 

 

(RP/DRP/LC) using BCDL mechanism, indicating the total number of

 

 

updates and total number of BCDL messages.

 

 

 

Labels in use

 

Local labels in use (installed in LFIB). These usually indicate the lowest

 

 

and highest label in use (allocated by applications). Furthermore, some

 

 

reserved labels (range: 0-15), such as explicit-nullv4, explicit-nullv6, are

 

 

installed in the forwarding plane.
