Checking the ATM Connection (Catalyst 8540 MSR)
To check ATM connection reachability and network connectivity on the Catalyst8540 MSR, use the
ping EXEC command, as shown in the following table:
You can ping a neighbor switch by selecting the segment loopback option. In privileged EXEC mode,
you can select various other parameters such as repeat count and timeout values.
Examples
The following example shows the ping command used in normal mode to check a virtual channel
connection (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)
Checking the ATM Connection (Catalyst 8510 MSR and
LightStream 1010)
To check ATM connection reachability and network connectivity on the Catalyst8510 MSR and
LightStream 1010 ATM switch router, use the ping EXEC command, as shown in the following table :
Command Purpose
ping atm interface atm card/subcard/port vpi
[vci] {end-loopback [destination] | seg-loopback
[destination]}
Checks the connection.
