Accessing the Switch
Checking Basic Connectivity
The switch offers the following commands for checking basic connectivity:
• ping
• traceroute
Ping
The ping command enables you to send Internet Control Message Protocol (ICMP) echo messages to a
remote IP device. The ping command is available for both the user and administrator privilege level.
The ping command syntax is:
ping {continuous} {start-size <number>} [<ip_address> | <hostname>] {from
<src_address> | with record-route | from <src_ipaddress> with record-route}
Options for the ping command are described in Table 9.
If a ping request fails, the switch continues to send ping messages until interrupted. Press any key to
interrupt a ping request.
Traceroute
The traceroute command enables you to trace the routed path between the switch and a destination
endstation. The traceroute command syntax is:
traceroute [<ip_address> | <hostname>] {from <src_ipaddress>} {ttl <TTL>} {port
<port>}
where:
• ip_address is the IP address of the destination endstation.
• hostname is the hostname of the destination endstation. To use the hostname, you must first
configure DNS.
