Chapter 10 Managing PNNI Routing
140 Avaya M770 ATM Switch User’s Guide
The output of this command displays a list of all local switch Reachable Addresses.
For each address it shows the following information:
Port 0 on the local slot indicates the CPU. Addresses registered on the CPU port
indicates services that are registered on the local switch, for example, the LECS
address as appears in the above example.
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, 152 bits) that is known
to PNNI.
Port, Type and
Scope Table Provide a table of all the local ports that this address is
registered on. For each port it provides the port type and scope.
Type The address type may be either Internal or Exterior (to the
PNNI domain). An exterior ATM address is an address that was
set statically using static routes.
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.
