Installation and Getting Started Guide
HP9300(config)# ip dns domain-name newyork.com
HP9300(config)# ip dns server-address 209.157.22.199 205.96.7.15 208.95.7.25
201.98.7.15
Syntax: ip dns server-address <ip-addr> [<ip-addr>] [<ip-addr>] [<ip-addr>]
In this example, the first IP address in the ip dns server-address... command becomes the primary gateway
address and all others are secondary addresses. Because IP address 201.98.7.15 is the last address listed, it is
also the last address consulted to resolve a query.
USING THE WEB MANAGEMENT INTERFACE
To map a domain name server to multiple IP addresses:
1. Log on to the device using a valid user name and password for read-write access. The System configuration
panel is displayed.
2. Do one of the following:
• On the HP 6208M-SX – Select the DNS
link to display the DNS panel.
• On a routing switch – Click on the plus sign next to Configure in the tree view, then click on the plus sign
next to IP, then select DNS
to display the DNS panel.
3. Enter the domain name in the Domain Name field.
4. Enter an IP address for each device that will serve as a gateway to the domain name server.
NOTE: The first address entered will be the primary DNS gateway address. The other addresses will be
used in chronological order, left to right, if the primary address is available.
5. Click the Apply button to save the change to the device’s running-config file.
6. Select the Save link at the bottom of the dialog. Select Yes when prompted to save the configuration change
to the startup-config file on the device’s flash memory.
Using a DNS Name To Initiate a Trace Route
Suppose you want to trace the route from a routing switch to a remote server identified as NYC02 on domain
newyork.com. Because the newyork.com domain is already defined on the routing switch, you need to enter only
the host name, NYC02, as noted below.
USING THE CLI
HP9300# traceroute nyc02
Syntax: traceroute <host-ip-addr> [maxttl <value>] [minttl <value>] [numeric] [timeout <value>]
[source-ip <ip addr>]
The only required parameter is the IP address of the host at the other end of the route. See the Command Line
Interface Reference for information about the parameters.
After you enter the command, a message indicating that the DNS query is in process and the current gateway
address (IP address of the domain name server) being queried appear on the screen:
Type Control-c to abort
Sending DNS Query to 209.157.22.199
Tracing Route to IP node 209.157.22.80
To ABORT Trace Route, Please use stop-traceroute command.
Traced route to target IP node 209.157.22.80:
IP Address Round Trip Time1 Round Trip Time2
207.95.6.30 93 msec 121 msec
NOTE: In the above example, 209.157.22.199 is the IP address of the domain name server (default DNS
gateway address), and 209.157.22.80 represents the IP address of the NYC02 host.
