Command Sets for Command Line Interface
subnet add <name> <i/f> <IP address> <mask>
subnet delete <name>
subnet flush
Description:
Lists defined subnets; defines a subnet; deletes a subnet definition; or
deletes all subnet definitions.
“<name>” is a label, that can be specified by “subnet add” and later
used by “subnet delete” to delete the subnet.
“<i/f>” is not used, but is present for historical reasons and must be
specified as either “.” or a valid interface name.
“<IP address>” is the IP address of the subnet being defined (only
those bits of “<dest>” corresponding to bits set in “<mask>” are
relevant).
“<mask>” is the subnet mask of the subnet being defined, specified as
four hexadecimal numbers separated by colons.
A subnet is defined automatically for each interface, with a name
formed by appending “.home” to the device name. The only
significant use for the “subnet” command is to change the masks for
these automatic subnets, if the default masks (see “device”
command) are not correct. (Subnet definitions for other subnets can
also be useful in conjunction with RIP version 1, which does not
communicate subnet masks, but this is not very common.)
Configuration saving saves this information.
Example:
DSL> ip device
# type dev file IP address
device ether ether //nice mtu 1500 192.168.2.1
device vlane ether //lane mtu 1500 192.168.55.1
DSL> ip subnet
subnet vlane.home . 192.168.55.0 ff:ff:ff:00 vlane
subnet ether.home . 192.168.2.0 ff:ff:ff:00 ether
DSL> ip subnet add vlane.home . 192.168.55.1 ff:ff:fc:0
DSL> ip subnet
subnet vlane.home . 192.168.52.0 ff:ff:fc:00 vlane
subnet ether.home . 192.168.2.0 ff:ff:ff:00 ether
