Accessing the Switch
You can specify up to eight DNS servers for use by the DNS client using the following command:
configure dns-client add domain-suffix <domain_name> | name-server <ip_address>
You can specify a default domain for use when a host name is used without a domain. Use the
following command:
configure dns-client default-domain <domain_name>
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} {size <start_size> {-<end_size}} {vr <vr_name>} [<ip_address>
| <hostname>] {from <src_ipaddress> | with record-route | from <src_ipaddress> with
record-route}
Options for the ping command are described in Table 7.
Table 7: 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.
count Specifies the number of packets to send.
dont-fragment Sets the don’t fragment bit when sending ping packets.
interval Specifies the time, in seconds, between packet sends.
tos Sets the IP header tos value.
