NOTE: The easiest way to enter the configuration mode is to hold down the ‘x’ key at the terminal (emulation) and then power up the VMSE. This will ensure that the x characters will arrive in time.

See Chapter 5 for more detail on using Serial communications to configure the VMSE.

Entering Network Configuration Mode_

To configure over the network, a Telnet connection to port 9999 must be established.

If you know the assigned IP address you can establish a Telnet connection to port 9999. Under Windows 95/98/NT, open an MS-DOS command window and type the command “telnet x.x.x.x 9999”, where x.x.x.x is an IP address already configured in the VMSE and 9999 is the desired TCP/IP port. Make sure you put a space between the x.x.x.x and 9999.

VMSE’s IP Address

Default IP Address

The VMSE is shipped with a default IP address of 0.0.0.0, which automatically enables the DHCP within the VMSE.

If DHCP is enabled on the VMSE, and if there is a DHCP server to respond to VMSE’s request when it’s booting up, the VMSE will then get an IP address, a gateway address, and a subnet mask from the DHCP server. These addresses will not be shown in the VMSE’s configuration screens (you will still see 0.0.0.0), however if you enter the “monitor mode” (see Chapter 5) and from 0> prompt type NC (upper case) you will be able to see the IP configuration of the VMSE.

NOTE: Using the ARP command (see below) you can always override the IP address given to the VMSE by your DHCP server.

If DHCP is enabled on the VMSE, but there is no DHCP server on the network, the VMSE's request will eventually time out and the unit will boot up with no IP address. As soon as a static IP address is assigned to the VMSE, the DHCP support will be disabled within the product. To re-enable DHCP support, the IP address should be set back to 0.0.0.0.
