To save the configuration changes using the Web management interface, select the Save link
at the bottom of the dialog. Select Yes when prompted to save the configuration change to the
startup-config file on the device’s flash memory. You also can access the dialog for saving
configuration changes by clicking on Command in the tree view, then clicking on Save to File.
Changes to memory allocation require you to reload the software after you save the changes to the
startup-config file. When reloading the software is required to complete a configuration change
described in this chapter, the procedure that describes the configuration change includes a step
for reloading the software.

IP state
The Internet Protocol, version 4
Enabled
NOTE: You cannot disable
IP.
n/a
IP address and
mask notation
Format for displaying an IP address and its network
mask information. You can enable one of the following:
•
Class-based format; example: 192.168.1.1
255.255.255.0
•
Classless Interdomain Routing (CIDR) format;
example: 192.168.1.1/24
Class-based
NOTE: Changing this
parameter affects
the display of IP
addresses, but you
can enter
addresses in either
format regardless
of the display
setting.
Address
Resolution
Protocol (ARP)
A standard IP mechanism that routers use to learn the
Media Access Control (MAC) address of a device on the
network. The router sends the IP address of a device in
the ARP request and receives the device’s MAC
address in an ARP reply.
Enabled
Time to Live
(TTL)
The maximum number of routers (hops) through which
a packet can pass before being discarded. Each router
decreases a packet’s TTL by 1 before forwarding the
packet. If decreasing the TTL causes the TTL to be 0,
the router drops the packet instead of forwarding it.
64 hops
Directed
broadcast
forwarding
A directed broadcast is a packet containing all ones (or
in some cases, all zeros) in the host portion of the
destination IP address. When a router forwards such a
broadcast, it sends a copy of the packet out each of its
enabled IP interfaces.
Note: You also can enable or disable this parameter on
an individual interface basis. Refer to
