Displaying the OAM Configuration
You can use either an ATM address prefix or an IP address as a ping destination. You can ping a neighbor
switch by selecting the segment loopback option. In privileged EXEC mode, you can select various ot her
parameters such as repeat count and timeout values.
Examples
The following example shows the ping command used in normal mode to check a VCC with a segment
loopback flow:
Switch# ping atm interface atm 3/0/0 50 100 seg-loopback
Type escape sequence to abort.
Sending Seg-Loopback 5, 53-byte OAM Echoes to a neighbor, timeout is 5 seconds:
.....
Success rate is 0 percent (0/5)
The following example shows the ping command used in extended mode to check a VCC with
end-to-end loopback flow:
Switch# ping
Protocol [ip]: atm
Interface [card/sub-card/port]: 3/0/0
VPI [0]: 0
VCI [0]: 16
Send OAM-Segment-Loopback ? [no]:
Target IP address:
Target NSAP Prefix:
Repeat count [5]:
Timeout in seconds [5]:
Type escape sequence to abort.
Sending end-Loopback 5, 53-byte OAM Echoes to a connection end point, timeout is
5 seconds:
.....
Success rate is 0 percent (0/5)
Note If you do not enable the OAM segment loopback option, the ping command uses an OAM end-to-end
loopback cell. If you do not provide a target address, the connection end point becomes the target.
Displaying the OAM Configuration
To display the OAM configuration, use the following EXEC command:
Command Purpose
ping atm interface atm card/subcard/port vpi
[vci] {[atm-prefix prefix] | end-loopback
[destination] | ip-address ip-address |
seg-loopback [destination]}
Checks the connection.
Command Purpose
