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:
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,
ipaddr 6 192.138.217.40 255.255.240.0
would set the
subnet mask for port 6 to 255.255.240.0. LCM responds by
redisplaying the current address table.
