78 ExtremeWare 7.2e Installation and 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 {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.
If a
ping
request fails, the switch continues to send
ping
messages until interrupted. Press any key to
interrupt a
ping
request. The statistics are tabulated after the ping is interrupted.
Traceroute
The
traceroute
command enables you to trace the routed path between the switch and a destination
endstation. The
traceroute
command syntax is:
traceroute <host name/ip> {from <source IP address>} {ttl <number>} {port <port
number>}
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.
