Basic IP parameters and defaults – Layer 3 Switches
Source-routed
packet
forwarding
A source-routed packet contains a list of IP
addresses through which the packet must pass to
reach its destination.
Enabled page 988
Internet Control
Message
Protocol (ICMP)
messages
The Brocade Layer 3 Switch can send the following
types of ICMP messages:
• Echo messages (ping messages)
• Destination Unreachable messages
Enabled page 989
ICMP Router
Discovery
Protocol (IRDP)
An IP protocol a router can use to advertise the IP
addresses of its router interfaces to directly
attached hosts. You can enable or disable the
protocol, and change the following protocol
parameters:
• Forwarding method (broadcast or multicast)
• Hold time
• Maximum advertisement interval
• Minimum advertisement interval
• Router preference level
NOTE: You also can enable or disable IRDP and
configure the parameters on an individual
interface basis. Refer to Table 165 on
page 959.
Disabled page 1004
Reverse ARP
(RARP)
An IP mechanism a host can use to request an IP
address from a directly attached router when the
host boots.
Enabled page 1007
Static RARP
entries
An IP address you place in the RARP table for RARP
requests from hosts.
NOTE: You must enter the RARP entries manually.
The Layer 3 Switch does not have a
mechanism for learning or dynamically
generating RARP entries.
No entries page 1008
Maximum
BootP relay
hops
The maximum number of hops away a BootP server
can be located from a router and still be used by the
router clients for network booting.

Domain name
for Domain
Name Server
(DNS) resolver
A domain name (example: brocade.router.com) you
can use in place of an IP address for certain
operations such as IP pings, trace routes, and Telnet
management connections to the router.
None configured page 970
DNS default
gateway
addresses
A list of gateways attached to the router through
which clients attached to the router can reach DNSs.
None configured page 970
IP load sharing A Brocade feature that enables the router to balance
traffic to a specific destination across multiple
equal-cost paths.
IP load sharing uses a hashing algorithm based on
the source IP address, destination IP address,
protocol field in the IP header, TCP, and UDP
information.
NOTE: Load sharing is sometimes called Equal Cost
Multi Path (ECMP).
