    ping atm interface atm

    Syntax

    ping atm interface atm interfaceSpecifier vpi vci
    [ end-loopback | seg-loopback [ destination ] ] [ count cellCount ]
    [ timeout #OfSeconds ]

    Release Information

    Command introduced before JunosE Release 7.1.0.

    Description

    Sets up the ATM interface or circuit to send loopback cells. There is no no version.

    Options

    • interfaceSpecifier—Particular interface; format varies according to interface type; see Interface Types and Specifiers
    • vpi—Virtual path identifier
    • vci—Virtual circuit identifier; by default F5 end-to-end loopback OAM cells are used for the ping operation
      • To send F4 segment loopback cells, set the VCI to 3.
      • To send F5 end-to-end loopback cells, set the VCI to 4.
    • end-loopback—Sends the ping to the connection endpoint
    • seg-loopback—Sends the ping to the first segment endpoint
    • destination—Value of the location ID included the loopback cell. The location ID is a 16-octet field, and the destination portion is 4 octets. You can set the destination to a specific location ID or to 0s (zeros) or 1s (ones). If the destination is set to:
      • 0s—Loopback location ID in the loopback cell is initialized to all 0s, and each segment endpoint in the network responds to the ping
      • 1s—Loopback location ID in the loopback cell is initialized to all 1s, and only the connection endpoint responds to the ping

      The default value is 0xFFFFFFFF, which causes the loopback location ID in the loopback cell to be initialized to all 1s.

    • cellCount—Number of OAM echo cells to send to the destination, in the range 1–32; default value is 5
    • timeout—Amount of time to wait for a response to the sent OAM cell. If no response is received when this time expires, the router sends the next cell. This process is repeated for the number of cells specified in the cellCount parameter.
    • #OfSeconds—Number of seconds in the timeout period, in the range 1–5; default value is 5
