Basic IP Parameters and Defaults – Layer 2 Switches
IP is enabled by default. The following tables list the Layer 2 Switch IP parameters, their default values, and where
to find configuration information.

information about this feature, see the chapter “Configuring IP Multicast Traffic Reduction” on page 18-1.
IP Global Parameters – Layer 2 Switches
Table 16.4 lists the IP global parameters for Layer 2 Switches.

Parameter Description Default See page...
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

parameter affects the
display of IP
addresses, but you
can enter addresses in
either format
regardless of the
display setting.

IP address A Layer 3 network interface address
Note: Layer 2 Switches have a single IP address
used for management access to the entire device.
Layer 3 Switches have separate IP addresses on
individual interfaces.
None configured
a
16-51
Default gateway The IP address of a locally attached router (or a
router attached to the Layer 2 Switch by bridges or
other Layer 2 Switches). The Layer 2 Switch and
clients attached to it use the default gateway to
communicate with devices on other sub-nets.
None configured 16-51
Address
Resolution
Protocol (ARP)
A standard IP mechanism that networking devices
use to learn the Media Access Control (MAC) address
of another device on the network. The Layer 2 Switch
sends the IP address of a device in the ARP request
and receives the device’s MAC address in an ARP
reply.
Enabled
Note: You cannot
disable ARP.
n/a
ARP age The amount of time the device keeps a MAC address
learned through ARP in the device’s ARP cache. The
device resets the timer to zero each time the ARP
entry is refreshed and removes the entry if the timer
reaches the ARP age.
Ten minute s
Note: You cannot
change the ARP age
on Layer 2 Switches.
