Hi, lane uses svc's to build data-direct connections between LECs, so in principle you can trace the path through all intermediate atm switches by simply doing show atm vc and writing down all the cross-connects on the NNI switches. Needless to say, this may take quite a while...
Another method is to simulate (compute) a path by using pnni command: "show atm pnni dtl node " executed on the atm switch. Below is an example: AMART#sh atm pnni dtl node 25 ubr AMART# Mar 14 21:33:37.933 MET: PNNI: UBR route request from ATM_OWNER_UNKNOWN Mar 14 21:33:37.933 MET: PNNI: To node AMERICA Mar 14 21:33:37.933 MET: PNNI: selected target node 25 Mar 14 21:33:37.933 MET: priority: 2 (25 0) pnni-remote-internal Mar 14 21:33:37.933 MET: PNNI: Compute On-Demand Route Based On Admin Weight Mar 14 21:33:37.933 MET: PNNI: Found A 3 Hop Route To Destination. Total AW = 15120 Mar 14 21:33:37.933 MET: PNNI: SOURCE ROUTE Mar 14 21:33:37.933 MET: DTL 1> 4 Nodes Mar 14 21:33:37.933 MET: AMART 80000000 (ATM0/0/0) Mar 14 21:33:37.933 MET: ALTO 0 Mar 14 21:33:37.937 MET: PACI 81103000 (ATM2/1/3) Mar 14 21:33:37.937 MET: AMERICA 0 Mar 14 21:33:37.937 MET: PNNI: Found 1 Ports To Next DTL Node 9 80000000 (ATM0/0/0) Mar 14 21:33:37.937 MET: PNNI: Send Source Route Reply To Requestor: Code PNNI_SUCCESS AMART# This output shows that the connection for ubr service class from node amart (8510msr) to node america (8510msr) has been computed with 3 hops and it goes through two intermediate switches (alto and paci, both 8540). Please read more on atm pnni to get a better understanding of this output.
