Assigning IP Addresses

3.1.1 Displaying IP Addresses

Use the ipaddr command to display IP addresses, subnet masks, and

MAC addresses of all ports on the FN100 you are conﬁguring.

LCM displays the current IP address table, for example:

FN100 > ipaddr

Port IP Address Address Mask MAC Address

1 198.113.121.149 255.255.255.0 00:40:27:07:b6:f6

2 0.0.0.0 255.0.0.0 00:40:27:07:b6:f7

3 0.0.0.0 255.0.0.0 00:40:27:07:b6:f8

4 0.0.0.0 255.0.0.0 00:40:27:07:b6:f9

5 0.0.0.0 255.0.0.0 00:40:27:07:b6:fa

6 0.0.0.0 255.0.0.0 00:40:27:07:b6:fb

7 0.0.0.0 255.0.0.0 00:40:27:07:b6:fc

8 0.0.0.0 255.0.0.0 00:40:27:07:b6:fd

3.1.2 Deleting an IP Address

Use the ipaddr <PORT#> 0.0.0.0 command to delete an IP address.

FN100 > ipaddr 6 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 using the ipaddr

<PORT#> <IPADDR> <MASK>

command. A subnet mask is a 32-bit address

mask used in IP to specify a subnet. If the subnet mask is 0.0.0.0, the

FN100 automatically converts the displayed mask to the standard default,

based on the IP address class of the port. (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.)

FN100 > ipaddr 6 192.138.217.40 255.255.240.0

For example, typing the above command sets the subnet mask for port 6

to 255.255.240.0. LCM responds by displaying the current address table.
