Chapter 10 Managing PNNI Routing

Due to the internal PNNI implementation in Avaya M770 ATM switch, the Master Agent module has the role of PDC (PNNI Designated Card). The PDC is the module that advertises the switch Nodal Information PTSE, and in hierarchical PNNI, this is the module that acts as PGL/LGN (in case the switch was elected Peer Group Leader). As a result, when the user uses the /route pnni config show command on a sub-agent module, some configuration parameters would be unknown to the sub-agent module. Those parameters would appear as dashed line. The parameters for the Logical Levels are:

•Operational status of a level

•Node ATM address

All above configuration variables are explained in subsequent chapters.

PNNI Administrative Status

Each PNNI node has an administrative (admin) status. This parameter indicates whether this node has to be administratively up or down. The physical node (on the 1st level) admin status is always up. The admin status of a higher level node (logical node) is determined by the user. It shall be up if the user wants the logical node to be active.

Note: The admin status of a logical node is important when you want the switch to become a Peer Group Leader, and an Logical Group Node at the higher level. In order to achieve that you'll have to set both the Leadership Priority of the node at the lower level to a value greater than 0, and the admin status of the next higher level to 'up'.

Showing PNNI node admin status

To show the admin status of a node use the following command:

Command: M15-155s8:/>route pnni config admin show 1

Output: Admin Status:

Level 1 - Up
