Troubleshooting PNNI Addresses and Address Summarization
Follow these steps to troubleshoot PNNI address prefix configuration:
Step 1 Use the show atm route command to confirm the list of all prefixes known by the node.
Switch# show atm route
Codes: P - installing Protocol (S - Static, P - PNNI, R - Routing control),
T - Type (I - Internal prefix, E - Exterior prefix, SE -
Summary Exterior prefix, SI - Summary Internal prefix,
ZE - Suppress Summary Exterior, ZI - Suppress Summary Internal)
P T Node/Port St Lev Prefix

Step 2 Verify that any expected address, prefix, or summary address is in the list of prefixes.
If the interface addresses do not have the expected prefix, verify that the correct prefix is present for the
active ATM address, using the show atm address command.
Step 3 To see the actual prefixes being advertised by a local node, use the show atm pnni database
internal-node-number command to get the PTSE ID number for the internal reachable address PTSE.
Step 4 Use the show atm pnni database internal-node-number ptse-id detail command to see the full contents
of the PTSE.

Step 5 To see if a prefix is being advertised at higher-levels, determine which switch router is acting as the
ancestor LGN by using the show atm pnni hierarchy network detail command.
Step 6 Use the show atm pnni database internal-node-number ptse-id detail command on the switch router
acting as the ancestor LGN.
Step 7 If the expected prefix is not being advertised at the higher-level, display the same information for the
child PGL. If it is not present at the child PGL level, but was present at the originating node, see the
“Troubleshooting the PNNI Database” section on page 6-30.
Step 8 If the prefix is present at the child PGL, but is missing for the parent LGN, verify that it is listed as up
by using the show atm route command.
