Displaying Ip Addresses; Deleting An Ip Address; Changing A Subnet Mask - Cabletron Systems Fast Network 10 User Manual

Chapter 3: Configuring Your FN10

3.1.1 Displaying IP Addresses

To display IP addresses, subnet masks, and MAC addresses of all ports on
the FN10 you are configuring, at the LCM prompt:
1. Type
ipaddr
LCM displays the current IP address table, for example:
Port IP Address
192.138.217.1
1
2 0.0.0.0
192.138.217.10
3
4 0.0.0.0
0.0.0.0
5
6 192.138.217.20
192.138.217.50
7
8 192.138.217.30

3.1.2 Deleting an IP Address

To delete an IP address, at the LCM prompt:
1. Type
ipaddr <PORT-NUMBER> 0.0.0.0
LCM responds by redisplaying the current IP address table.

3.1.3 Changing a Subnet Mask

You can optionally set the subnet mask for a port. A subnet mask is a
32-bit address mask used in IP to specify a particular subnet. If the subnet
mask is 0.0.0.0, the FN10 will automatically convert the displayed mask
to the standard default, based on the port's IP address class. (Class A
address masks are 255.0.0.0, Class B address masks are 255.255.0.0,
Class C address masks are 255.255.255.0.)
To change the subnet mask, at the LCM prompt:
1. Type
ipaddr <PORT-NUMBER> <IP ADDRESS> <SUBNET MASK>
For example,
subnet mask for port 6 to 255.255.240.0. LCM responds by
redisplaying the current address table.
