32 Summit 300-48 Switch Software User Guide
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.
