Troubleshooting PNNI Hierarchical Networks
Step 6 If the uplink PTSE is missing from the border node database, use the show atm pnni interface atm
command to verify the hello state for the interface to the other peer group.
Switch# show atm pnni interface atm 10/0/0
PNNI Interface(s) for local-node 1 (level=96):
Port ATM10/0/0 RCC is up , Hello state 2way_in with node Switch Error: Port
Looped back
Next hello occurs in 2 seconds, Dead timer fires in 67 seconds
Switch#
Step 7 If a lower level outside link interface is not in the common outside state, proceed to the “Checking the
PNNI Lowest-Level Interface” section on page 6-36.
Step 8 If the missing interface is a higher-level induced uplink, perform the same checks at the next lower
hierarchy level on the switch router acting as the LGN (and child PGL) node.
Step 9 If the derived aggregation token does not have the expected value, use the detail option to show
additional interface information.
Switch# show atm pnni interface atm 10/0/0 detail
PNNI Interface(s) for local-node 1 (level=96):
Port ATM10/0/0 RCC is up , Hello state 2way_in with node Switch Error: Port
Looped back
Next hello occurs in 6 seconds, Dead timer fires in 69 seconds

Step 10 Check for correct Aggregation Token local and remote configuration.
Note Mismatched aggregation configuration results in a derived aggregation token value of zero.
Step 11 Verify the expected upnode node ID and common peer group ID.
Checking the Induced Port on the LGNs
If the induced port value is missing or does not appear to be functional for an aggregate token and upnode
combination, use the following command to check the higher-level interfaces for the parent LGN local
node.
Use the following command to check the induced port on the LGN:
Command Purpose
show atm pnni interface local-node node-index Confirms the higher-level interfaces for
the parent LGN local node configuration.
