LABEL DESCRIPTION
Summary
address Enter a network IP address which can cover more than one network in order to reduce the
routing table size. For example, you can use 192.168.8.0/22 instead of using 192.168.8.0/24,
192.168.9.0/24, 192.168.10.0/24, and 192.168.11.0/24.
The third octet of these four network IP addresses is 00001000, 00001001, 00001010, 00001011
respectively. The first 6 digits (000010) are the common part among these IP addresses. So
192.168.8.0/22 can represent all of these networks.
Subnet mask Enter the subnet mask for this summary IP address which can cover multiple networks.
Apply Click Apply to save your changes to the Switch’s run-time memory. The Switch loses these
changes if it is turned off or loses power, so use the Save link on the top navigation panel to save
your changes to the non-volatile memory when you are done configuring.
Clear Click Clear to clear the fields to the factory defaults.
Cancel Click Cancel to not save the configuration you make and return to the last screen.
