Basic IP parameters and defaults

Each IP forwarding cache entry contains the IP address of the destination, and the IP address and
MAC address of the next-hop router interface to the destination. If the destination is actually an
interface configured on the Layer 3 Switch itself, as shown here, then next-hop information
indicates this. The port through which the destination is reached is also listed, as well as the VLAN
and Layer 4 QoS priority associated with the destination if applicable.
To display the IP forwarding cache, refer to “Displaying the forwarding cache” on page 92.
NOTE
You cannot add static entries to the IP forwarding cache, although the Virtual ADX does have options
to optimize the cache and increase the number of entries the cache can contain. Refer to
“Configuring system parameter settings” on page 16 for more information.
To increase the size of the IP forwarding cache, refer to “Configuring system parameter settings” on
page 16 for more information.
IP access policies
Brocade Layer 3 Switches provide a mechanisms for filtering IP traffic, which allows you to filter
packets based on Layer 3 and Layer 4 source and destination information. IP access policies allow
you to configure QoS based on sessions (Layer 4 traffic flows).
Brocade devices can store forwarding information for filtering in the session table.
Basic IP parameters and defaults
IP and IP-based protocols are disabled by default.
NOTE
For information about parameters in other protocols based on IP, refer to the configuration chapters
for those protocols.
When parameter changes take effect
Most IP parameters described in this chapter are dynamic. They take effect immediately, as soon
as you enter the CLI command or select the Web management interface option. You can verify that
a dynamic change has taken effect by displaying the running-config. To display the running-config,
enter the show running-config or write terminal command at any CLI prompt. (You cannot display
the running-config from the Web management interface.)
To save a configuration change permanently so that the change remains in effect following a
system reset or software reload, save the change to the startup-config file:
• To save configuration changes to the startup-config file, enter the write memory command
from the Privileged EXEC level of any configuration level of the CLI.
