PNNI Operational Status
The operational status of a physical node is always 'up'. The operational status of a
logical node may be either 'up' or 'down'. It will be up, if the logical node is active,
i.e. the lower level node is PGL, and the logical node is LGN. This is determined by
the Peer Group Leader Election (PGLE) protocol between the nodes at the lower
level Peer Group.
To show the operational status of a node use the following command. If the level
parameter is omitted, the operational status of all levels will be displayed.
Note: The operational status cannot be set by the user. The user determines the
administrative status, and the operational status is determined by the lower level
PGLE protocol.
PNNI Peer Group ID
Showing PNNI peer group ID
Use the following command to display the PNNI peer group ID.
The PNNI peer group ID is used when the PNNI protocol constructs the peer
groups in which topology databases are being synchronized. A link between two
neighbors that share the same peer group ID is considered an inside link, and a link
between 2 PNNI nodes that don’t have the same peer group is considered an
outside link. Topology databases are synchronized only over inside links.
Examples:
Note: This request will set default value (extracted
from ATM address) for node id.
