Foundry Switch and Router Installation and Configuration Guide
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.
NOTE: Foundry Layer 2 Switches also provide IP multicast forwarding, which is enabled by default. For
information about this feature, see "Configuring IP Multicast Traffic Reduction (Layer 2 Switches only)" on
page 10-56.
IP Global Parameters – Layer 2 Switches
Table 15.3 lists the IP global parameters for Layer 2 Switches.
Parameter Description
IP address and Format for displaying an IP address and its network
mask notation mask information. You can enable one of the
following:
•
•
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.
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.
Address A standard IP mechanism that networking devices
Resolution use to learn the Media Access Control (MAC) address
Protocol (ARP) 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.
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.
