Configuring IP parameters – Layer 3 Switches
The num parameter specifies the entry number. You can specify a number from 1 up to the
maximum number of static entries allowed on the device.
The ip-addr parameter specifies the IP address of the device that has the MAC address of the entry.
The mac-addr parameter specifies the MAC address of the entry.
The ethernet port command specifies the port number attached to the device that has the MAC
address of the entry.Specify the port variable in the format stack-unit/slotnum/portnum.
Changing the maximum number of entries the static ARP table can hold
If you need to change the maximum number of entries supported on a Layer 3 Switch, use the
method described in this section.
NOTE
The basic procedure for changing the static ARP table size is the same as the procedure for changing
other configurable cache or table sizes. Refer to the section “Displaying system parameter default
values” in the Brocade ICX 6650 Platform and Layer 2 Switching Configuration Guide.
To increase the maximum number of static ARP table entries you can configure on a Brocade Layer
3 Switch, enter commands such as the following at the global CONFIG level of the CLI.
Brocade(config)# system-max ip-static-arp 1000
Brocade(config)# write memory
Brocade(config)# end
Brocade# reload
NOTE
You must save the configuration to the startup-config file and reload the software after changing the
static ARP table size to place the change into effect.
Syntax: system-max ip-static-arp num
The num parameter indicates the maximum number of static ARP entriesdepending on the
software version running on the device.
Configuring forwarding parameters
The following configurable parameters control the forwarding behavior of Brocade Layer 3
Switches:
• Time-To-Live (TTL) threshold
• Forwarding of directed broadcasts
• Forwarding of source-routed packets
• Ones-based and zero-based broadcasts
All these parameters are global and thus affect all IP interfaces configured on the Layer 3 Switch.
To configure these parameters, use the procedures in the following sections.
