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 18.
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.
Table 18: Ping Command Parameters
Parameter Description
udp Specifies that UDP messages should be sent instead of ICMP echo messages.
When specified, from and with record-route options are not supported.
continuous Specifies ICMP echo messages to be sent continuously. This option can be
interrupted by pressing any key.
size Specifies the size of the ICMP request. If both the start_size and end_size are
specified, transmits ICMP requests using 1 byte increments, per packet. If no
end_size is specified, packets of start_size are sent.
<ipaddress> Specifies the IP address of the host.
<hostname> Specifies the name of the host. To use the hostname, you must first configure DNS.
from Uses the specified source address in the ICMP packet. If not specified, the address
of the transmitting interface is used.
with record-route Decodes the list of recorded routes and displays them when the ICMP echo reply is
received.
