•

traceroute

Ping
The command enables you to send Internet Control Message Protocol (ICMP) echo messages to a
ping
remote IP device. The
ping
The command syntax is:
ping
ping {udp} {continuous} {size <start_size> {-<end_size}} [<ip_address> | <hostname>]
{from <src_ipaddress> | with record-route | from <src_ipaddress> with record-route}
Options for the ping command are described in Table 20.

Traceroute
The command enables you to trace the routed path between the switch and a destination

endstation. The
traceroute
traceroute <host name/ip> {from <source IP address>} {ttl <number>} {port <port
number>}
where:
• is the IP address of the destination endstation.
ip_address
• is the hostname of the destination endstation. To use the hostname, you must first

end_size is specified, packets of start_size are sent.
Specifies the IP address of the host.
Specifies the name of the host. To use the hostname, you must first configure DNS.
Uses the specified source address in the ICMP packet. If not specified, the address
