TABLE 4 IP global parameters - Layer 3 switches (continued)
Parameter Description Default
IP address for certain operations such as IP
pings, trace routes, and Telnet management
connections to the router.
DNS default gateway addresses A list of gateways attached to the router through
which clients attached to the router can reach
DNSs. None configured
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.
You can specify the number of load-sharing
paths depending on the device you are
configuring. The maximum number of paths the
device supports is a value from 2 through 8. The
default value is 4. On the Brocade ICX 7750,
the value range for the maximum number of
load-sharing paths is from 2 through 32 which
is controlled by the
system-max max-ecmp
command.
NOTE
Load sharing is sometimes called
equal-cost multi-path (ECMP).
Enabled
Maximum IP load sharing paths The maximum number of equal-cost paths
across which the Layer 3 switch is allowed to
distribute traffic. Four
Origination of default routes You can enable a router to originate default
routes for the following route exchange
protocols, on an individual protocol basis:
• OSPF
• BGP4
Disabled
Default network route The router uses the default network route if the
IP route table does not contain a route to the
destination and also does not contain an explicit
default route (0.0.0.0 0.0.0.0 or 0.0.0.0/0). None configured
Static route An IP route you place in the IP route table. No entries
Source interface The IP address the router uses as the source
address for Telnet, RADIUS, or TACACS/
packets originated by the router. The
router can select the source address based on
either of the following:
• The lowest-numbered IP address on
the interface the packet is sent on.
• The lowest-numbered IP address on a
specific interface. The address is used
as the source for all packets of the
specified type regardless of interface
the packet is sent on.
The lowest-numbered IP address on the
interface the packet is sent on.
