ping command

This command tests the internal communication path between the CMM and an Flex System component by sending it a ping request.

If command syntax is not correctly entered, or if a command fails to run, an error message is returned. See Common errors for a list of error messages that apply to all commands or ping command errors for a list of error messages that are specific to the ping command.

Table 1. ping command. The command table is a multi-row, four-column table where each row describes a CMM CLI command option: column one lists command function, column two provides a detailed command description, column three shows command-option syntax, and column four lists valid command targets.
FunctionWhat it doesCommandTarget (see paths in Command targets)
Display IP addressesDisplays a list of index numbers and IP addresses for the specified command target.ping -i
Compute node:
  • blade[x]
  • where x is the node bay number.
I/O module:
  • switch[x]
  • where x is the I/O-bay number.
Ping compute node IP addressPings the specified compute node IP address to test communication between the compute node and the CMM.ping -i ip_address

where ip_address is the IP address to ping.

Note
Valid index numbers and IP addresses for components installed in the Flex System Enterprise Chassis can be seen by running the ping -i command, directed to a specific command target with no arguments.
Compute node:
  • blade[x]
  • where x is the node bay number.
Ping I/O-module IP addressPings the specified I/O-module IP address to test communication between the I/O module and the CMM.ping -i ip_address

where ip_address is the IP address to ping.

Note
Valid index numbers and IP addresses for components installed in the Flex System Enterprise Chassis can be seen by running the ping -i command, directed to a specific command target with no arguments.
I/O module:
  • switch[x]
  • where x is the I/O-bay number.
Ping compute node IP addressPings the specified compute node to test communication.ping -i index

where index is the index number for the compute node IP address to ping.

Note
Valid index numbers and IP addresses for components installed in the Flex System Enterprise Chassis can be seen by running the ping -i command, directed to a specific command target with no arguments.
Compute node:
  • blade[x]
  • where x is the node bay number.
Ping I/O-module IP addressPings the specified I/O module to test communication.ping -i index

where index is the index number for the I/O-module IP address to ping.

Note
Valid index numbers and IP addresses for components installed in the Flex System Enterprise Chassis can be seen by running the ping -i command, directed to a specific command target with no arguments.
I/O module:
  • switch[x]
  • where x is the I/O-bay number.
Example: To display the IP addresses of the I/O module in bay 2, while the Flex System Enterprise Chassis is set as the persistent command environment, at the system> prompt, type
ping -T switch[2] -i
To ping the second IP address of the I/O module in bay 2 using an index number, while the Flex System Enterprise Chassis is set as the persistent command environment, at the system> prompt, type
ping -T switch[2] -i 2
To ping the second IP address of the I/O module in bay 2 using an IP address, while the Flex System Enterprise Chassis is set as the persistent command environment, at the system> prompt, type
ping -T switch[2] -i fe80::a17:f4ff:fe89:a9ef

The following example shows the information that is returned from these commands:

system> ping -T switch[2] -i
