Chapter 13 Troubleshooting ATM Router Module Connections
Troubleshooting LANE Clients on ATM Router Module Connections
The following are the routing and node tables created for the network configuration on the Catalyst 8540
with an ATM router module shown in Figure 13-8.
Routing Table
Network 100, Primary network, FastEth 1/0/0
Network 200, Primary network, ATM 3/0/0.1
Node Table:
FastEth 1/0/0 100.00ab.cdef.0001 Interface no.
ATM 3/0/0.1 200.00ab.cdef.0002 Data VC
Troubleshooting IP switching with the ATM router module configured between the ATM and Ethernet
interfaces is essentially the same as described in the “Troubleshooting IPX Layer 3 Routing” section on
page 11-38. However, you must confirm connections and adjacencies through the ATM router module.
General ATM Router Module Troubleshooting
Use the following commands to troubleshoot general ATM router module connections:
Use the following commands to troubleshoot the ATM router module LECs and the configuration:
Step 1 Use the ping command to confirm the LEC connection to the end station.
Switch# ping 128.250.20.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 128.250.20.1, timeout is 2 seconds:

Check the if_vc= field and make note of the interface VC number. In this case, the interface VC is “45.”
Command Purpose
ping ip-address Tests the network node reachability.
show epc ifmapping interface-map-number Displays interface mapping to CAM
interface number.
show epc ip-address interface atm
card/subcard/port ip-address
Displays all adjacent IP addresses for the
specified interface.
