Parameter

Meaning

 

 

 

 

 

 

 

state

The current status of BGP backoff. NORMAL is displayed

 

 

 

when BGP backoff is not active, and BGP is either

 

 

 

processing normally, or can be re-established if peers are

 

 

 

disabled. BACKED OFF is displayed when system memory

 

 

 

use has reached its upper threshold and BGP processing is

 

 

 

halted. PEER DISABLED is displayed when the consecutive or

 

 

 

total backoff limits have been reached and system memory

 

 

 

use is still above the lower threshold. DISABLED is displayed

 

 

 

when backoff functionality has been disabled by the user.

 

 

 

 

 

 

Mem Upper Threshold Value

The percentage of system memory use that triggers BGP to

 

 

 

back off. This threshold is set using the backoff parameter.

 

 

 

 

 

 

Mem Upper Notify

Whether BGP is monitoring the upper or lower thresholds

 

 

 

of the system memory use. When TRUE, BGP is monitoring

 

 

 

the upper threshold and its state is NORMAL.

 

 

 

 

 

 

Mem Lower Threshold Value

The percentage of system memory use that the router or

 

 

 

switch must fall below before BGP backoff will end. This

 

 

 

threshold is set using the low parameter.

 

 

 

 

 

 

Mem Lower Notify

Whether BGP is monitoring the upper or lower threshold of

 

 

 

the system memory use. When TRUE, BGP is monitoring the

 

 

 

lower threshold and is in a BACKED OFF or PEER DISABLED

 

 

 

state.
