Cisco Cisco IOS Software Release 12.0(17)S

Cause code

May be one of the following values:

ack timer expiry—add link synchronization process has been 
exhausted.

bundle link idle—peer’s bundle link is idle. This usually occurs 
when the peer’s bundle interface is shut.

inconsistent bundle—peer already has this bundle associated 
with a different bundle.

loopback detected—local bundle link’s physical line is looped 
back.

other—indicates a LID mismatch, or that the ID length from 
the peer is too long, or that there has been a failure to allocate 
ID memory.

unexpected Add_link—Add_link message is received when the 
bundle link is already in the up state. This code may appear 
when the line protocol is being set up, but will disappear once 
the connection has stabilized.

Bundle interface

Bundle interface with which the bundle link is associated.

Ack timer 

Number of seconds the bundle link will wait for a hello 
acknowledgment before resending a hello message or resending an 
Add_link message used for initial synchronization.

Hello timer

Interval at which a bundle link sends out hello messages.

Max retry count

Maximum number of times a bundle link will resend a hello 
message before receiving an acknowledgment or resending an 
Add_link message.

Current count

Number of retries that have already been attempted.

Peer lid

Bundle link identification name of the peer end of the link.

Statistics

Statistics for each bundle link will be displayed.

Add_link sent

Number of Add_link messages sent. Add_link messages notify the 
peer endpoint that the local endpoint is ready to process frames.

Add_link rcv'd

Number of Add_link messages received.

Add_link ack sent

Number of Add_link acknowledgments sent. Add_link 
acknowledgments notify the peer endpoint that an Add_link 
message was received.

Add_link ack rcv'd

Number of Add_link acknowledgments received.

Remove_link sent

Number of Remove_link messages sent. Remove_link messages 
notify the peer that on the local end a bundle link is being removed 
from the bundle.

Remove_link rcv'd

Number of Remove_link messages received.

Remove_link_ack sent

Number of Remove_link acknowledgments sent. Remove_link 
acknowledgments notify the peer that a Remove_link message has 
been received.
