Configuring ARP parameters
7
The <ip-addr> command 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 <slot/port> command specifies the port number attached to the device that has the
MAC address of the entry.
The arp command allows you to specify only one port number. To create a static ARP entry for a
static MAC entry that is associated with multiple ports, specify the first (lowest-numbered) port
associated with the static MAC entry.
Changing the maximum number of entries the static ARP table can hold
The default number of entries in the static ARP table on the device are as follows:
• Default maximum: 8192
• Configurable maximum: 65536
NOTE
You must save the configuration to the startup configuration 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. Refer to
“Displaying and modifying system parameter
default settings” on page 133.
To increase the maximum number of entries in the static ARP table you can configure, enter
commands such as the following at the global CONFIG level of the CLI.
BigIron RX(config)# system-max ip-static-arp 4000
BigIron RX(config)# write memory
BigIron RX(config)# end
BigIron RX# reload
Syntax: system-max ip-static-arp <num>
The <num> parameter indicates the maximum number of static ARP entries: 2048 - 4096 (default:
2048).
The maximum number of static ARP entries is 16384 (default: 2048).
NOTE
As of release 2.4.00, the system-max static-arp command no longer affects memory allocation for
static ARPs. Instead, the BigIron RX dynamically allocates memory for static-arp entries as required
and this is only limited by the memory allocation for all ARP entries, specified by the system-max
ip-arp command.
Creating a floating static ARP entry
You can create a static ARP entry without port assignments.
