Avaya M770 ATM Switch User’s Guide

Setting PNNI peer group ID

Use the following command to set the PNNI peer group ID.

Setting PNNI peer group ID to default value

Use the following command to set the PNNI Peer Group ID to its default value. The 
default value is derived from the PNNI level and the switch’s prefix. The first byte 
of the peer group ID is the level indicator. The following bytes must be prefixes of 
ATM End System Addresses as defined in the PNNI specification (af-pnni-
0055.000). The peer group is encoded with the 104-n rightmost bits set to zero, 
where n is the level.

The Peer Group Leader Election (PGLE) submenu is important in hierarchical 
PNNI, where this protocol takes place while electing the PGL. The most important 
parameter here is the Leadership Priority, which indicates the priority of each node 
for becoming a PGL. Leadership Priority of 0 indicates that the node will not 
become a PGL. 

Command:

M15-155s8:/>route pnni config pg_id set <level> 

< pg id >

Parameters

level (1-5)

Internal level number: 1 is the lowest (physical) 

node

pg id

14 hexadecimal bytes separated by a decimal. The 

first byte is the level (1-104 in Hex). 104-level 

rightmost bits should be zero.

Output: 

Warning: This request will change the peer group id. It will 

also change the node level and the first byte of the node id to 

<level scope in hex>.

Command:

M15-155s8:/>route pnni config pg_id default <level>

address) for peer group id.
