TABLE 3 IP interface parameters - Layer 3 switches (continued)
Parameter Description Default
DHCP Client-Based Auto-Conguration Allows the switch to obtain IP addresses from a
DHCP host automatically, for either a specied
(leased) or innite period of time.
Enabled
DHCP Server All FastIron devices can be congured to
function as DHCP servers.
Disabled
UDP broadcast forwarding The router can forward UDP broadcast packets
for UDP applications such as BootP. By
forwarding the UDP broadcasts, the router
enables clients on one subnet to nd servers
attached to other subnets.
NOTE
To completely enable a client UDP
application request to nd a server
on another subnet, you must
congure an IP helper address
consisting of the server IP address or
the directed broadcast address for
the subnet that contains the server.
Refer to the next row.
The router helps forward broadcasts for the
following UDP application protocols:
• bootps
• dns
• netbios-dgm
• netbios-ns
• tacacs
• tftp
• time
IP helper address The IP address of a UDP application server
(such as a BootP or DHCP server) or a directed
broadcast address. IP helper addresses allow the
router to forward requests for certain UDP
applications from a client on one subnet to a
server on another subnet.
None congured
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 nd conguration
information.
NOTE
Brocade Layer 2 switches also provide IP multicast forwarding, which is enabled by default. For information about this feature,
refer to "IP Multicast Trac Reduction" in the FastIron Ethernet Switch IP Multicast Conguration Guide.
