Accessing the Switch
For example, if you specify the domain “xyz-inc.com” as the default domain, then a command such as
ping accounting1
will be taken as if it had been entered
ping accounting1.xyz-inc.com
.
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 | count <count>]} {start-size <start-size>} {end-size
<end-size}} {interval <interval>} {ttl <ttl>} {tos <tos>} {vr <vrid>} <host>
Options for the ping command are described in Table 7.
If a
ping
request fails, the switch continues to send
ping
messages until interrupted. Press [Control] + C
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 {vrid <vrid>} <host> {from <source IP address>} {ttl <number>} {port <port
number>}
Table 7: Ping Command Parameters
Parameter Description
udp Specifies that the ping request should use UDP instead of ICMP.
continuous Specifies that UDP or ICMP echo messages to be sent continuously. This option can
be interrupted by pressing any key.
start-size Specifies the size, in bytes, of the packet to be sent, or the starting size if
incremental packets are to be sent.
end-size Specifies the end size, in bytes, of the packet to be sent, when incremental packets
are sent.
vr Specifies the virtual route to use for sending out the echo message. If not specified,
the virtual router assigned to the default VLAN is used.
tos Sets the TOS value.
ttl Sets the TTL value.
dont-fragment Sets the IP to not fragment the bit.
interval Sets the time interval between sending out ping requests.
host Specifies a IPV4 host to ping.
