The DNS client can resolve host names to both IPv4 and IPv6 addresses.
In addition, the nslookup utility can be used to return the IP address of a host name.
You can specify up to eight DNS servers for use by the DNS client using the following
command:
configure dns-client add
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
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 {count <count> {start-size <start-size>} | continuous {start-size <start-size>} |
{start-size <start-size> {end-size <end-size>}}} {udp} {dont-fragment} {ttl <ttl>} {tos
<tos>} {interval <interval>} {vr <vrid>} {ipv4 <host> | ipv6 <host>} {from} {with
record-route}
Options for the ping command are described in Table 10.
