Domain Name Service Client Services
The Domain Name Service (DNS) client in ExtremeWare XOS augments the following commands to
allow them to accept either IP addresses or host names:
●
telnet
●
download bootrom
●
download image
●
ping
●
traceroute
●
configure radius server
●
configure tacacs server
In addition, the
nslookup
utility can be used to return the IP address of a hostname.
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
NOTE
The Aspen 8810 switch does not support user-created virtual routers. You must use the
vr
option for these
commands when running them on VR-Mgmt.
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>}
