Temporarily Reconfiguring a Host for Command Line Management
You can temporarily reconfigure an IP host in order to set the server’s
IP parameters to allow in-band Telnet access.
If you wish to set the server’s basic IP parameters in this fashion, the
host must be on the same Ethernet segment as the IntraPort’s server’s 0
interface. You can then do the following:
1. Set the host’s IP address to 198.41.12.2, with a Class C subnet
mask (255.255.255.0) and then Telnet to 198.41.12.1.
2. Enter th e defau lt pas swo r d letmein at the password prompt. The
command line interface prompt will appear on the screen.
3. Use the configure command and set the IPAddress, SubnetMask,
and IPBroadcast keywords in the IPE t hernet 0 section.
4. Use the sa ve command to save the changes to the device’s
Flash ROM.
5. Change the host’s configuration back to its original settings.
See the next section (Setting Up Telnet Operation) for information on
setting the server to allow Telnet access from hosts on its network.
Setting Up Telnet Operation
Telnet is a remote terminal communications protocol based on
TCP/IP. With Telnet you can log into and manage the IntraPort 2/2+
from anywhere on your IP internetwork, including across the Internet
if your security setup allows it.
To manage the server with Telnet, you must:
1. Run Telnet client software on your local computer, which will
communicate with the Telnet server built into the IntraPort 2/2+.
2. You must also set some basic IP parameters in the server. The
required parameters for Telnet access to an interface are the IP
address, IP subnet mask, and IP broadcast address. There are sev-
eral ways to set them.
•You may set them using text-based configuration either
out-of-band via the Console interface or in-band via a recon-
figured IP host. Instructions for setting up these two methods
were given earlier in this chapter. Once you have set up the
