ATM Configuration and Troubleshooting Guide

Getting Status Information with ATM Commands
Command Examples
Chapter 7150
• Two VCs (0,202 and 0,203) that are carrying LLC ISO 8802/2
multiplexed types of traffic (for example, MPOA MPC-to-MPS,
MPOA MPC-to-MPC, or LLC V2-capable LEC-to-LEC traffic).
LLC LEC, MPC is in the “Use” field for each of these VCs.
The “Index” column in the output refers to the “Current Traffic
Parameters Configurations” table, displayed with the command
atmmgr card_inst_num show -t. See “Getting Adapter Traffic
Parameter Configurations (SVCs/PVCs)” on page 153 for an example of
the table.
Getting a LEC-to-LEC SVC’s Destination IP Address
To display the destination IP address for a LEC-to-LEC SVC, follow
these steps:
Step 1. Type atmmgr card_inst_num show -v to get a list of all VCs.
Step 2. Identify the LEC-to-LEC SVC’s VPI/VCI number from the list of VCs.
Step 3. Use the command elarp -n net_interface to view the contents of the
LE_ARP cache for the ELAN interface.
Step 4. Identify the VPI/VCI number of the LEC_to_LEC SVC that you obtained
using the atmmgr card_inst_num show -v command, and note the
“Destination MAC address.”
Step 5. Use the command arp -a to get a list of the ARP system’s ARP cache,
showing the destination IP-to-MAC address mappings.
Step 6. Identify the IP address that is associated with the destination MAC
address.
Getting Information for a Specific VPI and VCI
You can get the following information about a specific VC:
• The destination ATM address (for SVCs only).
• The destination IP address (for a Classical IP interface only).
• The traffic type and traffic configuration used by the VC.
The following example displays information for the SVC with a VPI and
VCI of 0,205 (a card instance number of 0 is used):
atmmgr 0 show -v 0,205
