Aborting a Ping Session Testing Network Connectivity Using ATM Interface Ping (Normal Mode).Testing Network Connectivity Using ATM Interface Ping (Interactive Mode). Testing Network Connectivity Using ATM Interface Ping (Normal Mode).See the following sections for tasks that use ping commands to test network connectivity in an ATM network. The default value of the timeout is 2 seconds on Cisco routers. The destination is able to send an OAM loopback response cell back to the source within a predetermined time called a timeout.The OAM command loopback cell reaches the destination.The ping is successful only when the following criteria are met: The ping command first sends an OAM command loopback cell to the destination and then waits for an OAM response loopback cell. The simpler ping command provides an interactive mode for testing ATM network connectivity. The round-trip delay in communicating with the host.Whether a remote host is active or inactive.The ping atm interface atm command is used to determine the following: Segment loopback-Verifies PVC integrity to the immediate neighboring ATM device.End loopback-Verifies end-to-end PVC integrity.The ping atm interface atm command provides two ATM OAM ping options: This is a common method for testing the accessibility of the devices. The status of the PVC is displayed when a response to the OAM packet is received. The ATM OAM Ping feature modifies the ping command, which can be used to send an OAM packet to verify the PVC connectivity. Uses for ATM OAM Ping Command Uses for ATM OAM Ping Command.To use the ATM OAM Ping, you must understand the following concept: Loopback location identification Information About ATM OAM Ping.Network service access point (NSAP) addresses.The ATM OAM Ping feature does not support pings based on the following: (For Cisco 827 series routers, the virtual circuit need not exist.)įor information about how to configure ATM PVCs, see the section " Configuring PVCs " in the chapter " Configuring ATM" in the Cisco IOS Wide-Area Networking Configuration Guide, Release 12.3. Command Reference Prerequisites for ATM OAM PingĪ PVC corresponding to the virtual path identifier (VPI) and virtual channel identifier (VCI) values entered with the ping command should already exist.Configuration Examples for ATM OAM Ping.If you do not have an account or have forgotten your username or password, click Cancel at the login dialog box and follow the instructions that appear. Use Cisco Feature Navigator to find information about platform support and Cisco IOS software image support. This feature was integrated into Cisco IOS Release 12.2(27)SBA.įinding Support Information for Platforms and Cisco IOS Software Images This feature was integrated into Cisco IOS Release 12.2(18)SXE. This feature was integrated into Cisco IOS Release 12.2(25)S. This feature was integrated into Cisco IOS Release 12.2(13)T. The ATM OAM Ping feature allows the network administrator to verify PVC integrity and facilitates ATM network troubleshooting.įeature History for the ATM OAM Ping Feature The ATM OAM Ping feature sends an ATM Operation, Administration, and Maintenance (OAM) packet to confirm the connectivity of a specific permanent virtual circuit (PVC).
