Pinging from an ATM Circuit or OAM F4 Circuit

Pinging from an ATM Circuit or OAM F4 Circuit
You can ping from an ATM circuit or OAM F4 circuit by using the ATM ping command. Only one ping can be executed at a time on a selected ATM circuit, but up to 12 pings can be executed at the same time across the ATM interface. For the ping to work, the OAM admin status on the ATM interface must be enabled, and the line interface status must be up.

An ATM ping may abort if the line interface goes down, if the OAM admin status is disabled, or if the circuit is deleted. Error messages appear in either the Results field or in pop-up messages.

To ping an ATM circuit or OAM F4 circuit:

Select an ATM circuit or OAM F4 circuit in the list area, right-click, and select ATM Ping.

The ATM Ping dialog box appears. Depending on the type of circuit being pinged, additional fields are displayed in the dialog box. See the following figures. Note that the circuit's VPI, VCI, and VCD values are automatically entered.
Set the ping parameters (Table 58).
 Table 58:  ATM Ping Parameters 

 Parameter
 Description

 VPI

 Virtual path identifier of the selected circuit; cannot edit


 VCI

 Virtual circuit identifier of the selected circuit; cannot edit


 VCD

 Virtual circuit descriptor of the selected circuit; cannot edit


 Loopback Cell Type

 Specifies type of OAM loopback cells to use for the ping request

   End-to-End—Use end-to-end loopback cells
   Segment—Use segment OAM loopback cells



 Loopback Location ID (0x)


   Loopback location ID for the destination
   Should correspond to a loopback location ID previously established on a network component
   Applicable only when Segment is selected as the loopback cell type
   Hexadecimal value; range 0-ffffffff; default ffffffff



 Probe Count

 Number of ping probes (OAM cells) to be sent to complete the test; range 1-30; default 5






 Timeout (sec)

 Specifies the timeout value for a remote ping operation; range 1-5 seconds; default 5


 Results

 Contains the ping results or ping error messages
Click Ping.
Results are displayed in the Results field.
