Echo Requests from the switch. You can specify only one IP
address.
hostname
Specifies the host name of the network device to receive the ICMP
Echo Requests from the switch. You can specify only one host

Description
Use this command to instruct the switch to send ICMP Echo Requests to a
network device with an IPv4 address. You can use the command to
determine whether there is an active link between the switch and another
network device, such as a RADIUS server or a Telnet client, or to
troubleshoot communication problems. To ping an IPv6 address, see
“PING IPv6” on page 151.
In order to specify the host name parameter, the switch needs a
connection to a name server. To accomplish this, the switch can obtain a
name server automatically with DHCP. See “IP ADDRESS DHCP” on
page 304 for information about how to set the switch to DHCP.
To send ICMP Echo Requests the switch must be configured with a
management IP address. For background information, refer to
The switch sends the ICMP Echo Requests from the ports of the
VLAN assigned the management IP address. The device the switch
is pinging must be a member of that VLAN or must be accessible
through routers or other Layer 3 devices.
