Configuring IP
December 2000 15 - 33
• If the device does not have any static ARP entries, the Static ARP configuration panel is displayed, as
shown in the following example.
• If a static ARP entry is already configured and you are adding a new entry, click on the Add Static ARP
link to display the Static ARP configuration panel, as shown in the following example.
• If you are modifying an existing static ARP entry, click on the Modify button to the right of the row
describing the entry to display the Static ARP configuration panel, as shown in the following example.
6. Enter the IP address. The address must be for a device that is directly connected to the Layer 3 Switch.
7. Enter the MAC address.
8. Select the port that the static ARP entry is to be assigned to from the pull down menu.
9. Click the Add button to save the change to the device’s running-config file.
10. Select the Save link at the bottom of the dialog. Select Yes when prompted to save the configuration change
to the startup-config file on the device’s flash memory.
Changing the Maximum Number of Entries the Static ARP Table Can Hold
Table 15.5 on page 15-34 lists the default maximum and configurable maximum number of entries in the static
ARP table that are supported on each type of Foundry Layer 3 Switch. If you need to change the maximum
number of entries supported on a Layer 3 Switch, use either of the following methods.
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.
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. See “Displaying and Modifying System Parameter Default Settings” on
page 10-70.
USING THE CLI
To increase the maximum number of entries in the static ARP table you can configure on a BigIron Layer 3 Switch
using a 512MB Management IV module, enter commands such as the following at the global CONFIG level of the
CLI:
BigIron(config)# system-max ip-static-arp 8000
BigIron(config)# write memory
BigIron(config)# end
BigIron# reload
Syntax: system-max ip-static-arp <num>
The <num> parameter indicates the maximum number of static ARP entries and can be a number in one of the
following ranges, depending on the device you are configuring. Table 15.5 lists the default maximum and range of
configurable maximums for static ARP table entries supported on each type of Foundry Layer 3 Switch.
