Chapter 10 Managing PNNI Routing

each address it shows the following information:

Field

Description

 

 

 

 

Len

The address length in bits. The maximum length would be 152

 

bits, as ATM routing is done for only 19 bytes addresses. The last

 

byte of the ATM address (the selector) has local significance

 

only, and does not affect routing.

 

 

Prefix

The ATM address prefix (up-to 19 bytes) that is known to PNNI.

 

 

Port Type

Provide a table of all the local ports that this address is registered

and Scope

on. For each port it provides the Port Type and Scope.

Table

 

 

 

Type

The address type for each port it can be either Internal address or

 

Exterior address.

 

 

Scope

This field indicates the scope of advertisement of the address.

 

The scope value indicates up to which hierarchical level the

 

address will be advertised. The lower the value, the wider the

 

domain that gets the address. Value of 0 indicates that the

 

address will be advertised through out the entire PNNI domain.

 

The advertisement scope is mapped from the UNI scope. For

 

more details refer to the Static Routing chapter.

 

 

Port 0 on the local slot indicates the CPU. Addresses registered on the CPU port indicates services that are registered on the local module, for example, the LECS address as appears in the above example.

PNNI Local Switch Information

The following commands show information for the entire switch.

Local Switch links

This command displays all PNNI uplinks that were advertised by any module in the switch. Uplinks are advertised for Outside links (links to other peer groups) that their Hello protocol had reached the final state of 'commonOutside'..

Command: M15-155s8:/>route pnni local switch link
