Setting The Interface's Hostname; Preventing The Interface From Taking Other Configurations - HP ProCurve 7000dl Series Basic Management And Configuration Manual

Setting the Interface's Hostname

If necessary, you can change the hostname for the single interface only. For
example, you could register for a hostname with a dynamic DNS service. (See
Chapter 12: Domain Name System (DNS) Services.) You could then ask your
ISP to advertise this hostname, which you specify with the following command:
Syntax: ip address dhcp hostname <"name">
You should put quotation marks around the hostname. For example, you might
enter:
ProCurve(config-fr 1.101)# ip address dhcp hostname "procurve"
Remember that you must override client identifiers and hostnames at the same
time that you enable the DHCP client. For example:
ProCurve(config-fr 1.101)# ip address dhcp client-id eth 0/1 hostname "procurve"
Preventing the Interface from Taking Other
Configurations
One of the advantages for an interface that receives a DHCP address is that it
can receive other configurations as well. This can be particularly useful for
connections to the Internet. The interface can receive an IP address and DNS
server address at the same time.
Interfaces running the DHCP client can receive these configurations:
a default route
a domain name
a DNS server
However, the seeming advantage also poses risks. For example, when a router
has more than one WAN connection, the default route should not always be
to the server providing the temporary address. Some organizations prefer to
control their own settings for routing, domain names, and DNS, rather than
relying on a remote or foreign device.
If you want to prevent the interface from taking configurations other than an
IP address, you must do so before you activate the DHCP client.
