ping

Last Updated : Mar 14, 2024 |

When debugging connectivity problems, ping command helps to indicate the low-level connectivity. If an external ping works but higher-level applications such as DCS, CMS, or INTUITY do not, there is probably low-level connectivity to the board. Interrogate the switch for other clues as to why the higher-level application is not working.

The ping command checks low-level connectivity between the two IP-connected peers: a destination and a source.

  • The destination can be:

    • an IP address (ip-address addr)

    • a node (node-name name)

  • The source can be:

    • a Softphone, IP telephone, or Remote Office (R300) telephone (source port-id).

Use this test to check the circuitry in the data path for a peer-to-peer IP layer connection. This test is nondestructive.

Caution:

Repeated ping tests can consume a lot of bandwidth and can bog down a network. If the network is already loaded, a ping test can fail even if there is a connectivity between the source and the destination.

The two ping command options are as follows:

  • ip-address

  • node-name

The syntax for both the commands are as follows:

Syntax 1

ping ip-address

Syntax 2

ping node-name name [ source port-id ] [ packet-length len ] [ repeat # ]
IP Address to ping

Specify a valid IPv4 or IPv6 address of the device to ping.

node-name name

The name of the node to ping. Use display node-names ip to see what IP nodes are administered.

source port-id

The virtual endpoint port ID to use as the source of the ping. This can be the virtual endpoint port ID of a softphone, IP telephone, or Remote Max (R300) telephone. Use status station ext to determine the virtual endpoint port ID of a telephone.

packet-length len

The packet length of the ping packet, from 64 to 1500. If packet-length is not given, the default packet length is 64 bytes. Specifying a longer packet length in the command line can show:

  • if a router or host has a problem fragmenting or reassembling transferred packets.

  • a more complete indication of the link status.

repeat #

The number of times to repeat the ping test. See Caution above before using.

ping field descriptions

Field

Description

End-pt IP or End-pt Node-name

The destination of the ping command.

Port

The slot or port of the source.

Port Type

The maintenance object name of the source.

Result

PASS, FAIL, or ABORT.

Time (ms)

The round-trip time (in milliseconds) of the ping.

Error Code

Identifies problems associated with the circuitry in the data path for a peer-to-peer IP layer connection. For the meaning of the error code and troubleshooting procedures, see the Port Type’s maintenance object description in the Maintenance Procedures for Avaya Aura® Communication Manager, Branch Gateways and Servers. The MO description indicates the type of ping test used and the meaning of that ping test’s error codes.

Error messages

Message

Description

www.xxx.yyy.zzz IP address not assigned

The system cannot find the IP address.

IP address not reachable from this board

The IP address is not in the route table of the specified board.

“xxxx” Invalid IP address

Invalid IP address parameter. Must be in www.xxx.yyy.zzz format.

“CCcss” is an invalid identifier; please press HELP

Invalid board location (when using board).

Error encountered, could not complete request

An internal error, the port through which the IP address is reached could not be found.

Invalid range

The packet size is greater than 1500 or less than 64 bytes in length, or there are invalid or unrecognized parameters.
