CLI: Ping Test

The Ping (Packet InterNet Groper) test uses Internet Control Message Protocol (ICMP) echo requests and ICMP echo replies to determine if another device is alive. It also measures the amount of time it takes to receive a reply from the specified destination. The Ping command has several extended commands that allow advanced checking of destination availability.

Syntax: ping <ip-address hostname switch-num> [repetitions <1-10000>] [timeout <1-60>] [source <ip-address> <vlan-id>] [data-size <0 - 65471>] [data-fill <0-1024>]

ping6 <ip-address hostname switch-num> [repetitions <1-10000>] [timeout <1-60>] [source <ip-address> <vlan-id>] [data-size <0 - 65471>] [data-fill <0-1024>]

Sends ICMP echo requests to determine if another device is alive.

Note: For information about ping6, see the “IPv6 Configuration

Guide” for your switch.

<ip-address hostname>

Target IP address or hostname of the destination node being pinged.

repetitions <1-10000>

Number of ping packets sent to the destination address.

Default: 1

timeout <1-60>

Timeout interval in seconds; the ECHO REPLY must be received before this time interval expires for the Ping to be successful.

Default: 5

source <ip-addr hostname >

Source IP address or hostname. The source IP address must be owned by the router. If a VLAN is specified, the IP address associated with the specified VLAN is used.
