As a short static ARP entry is included into the number of normal ARP entries 
like a normal long static ARP entry, if a card is configured to support up to 8K 
aggregation ARP entries, the card does not support the configuration of 
neither kinds.

The operations in configuring ARP table size dynamically include:

■

Configuring the maximum number of ARP entries supported by a card

■

Configuring the maximum number of aggregation ARP entries supported by a 
card

■

Configuring the maximum number of ARP entries supported by the switch

To cancel the configurations, use the corresponding undo commands.

■

Restart the system to make the above dynamic ARP configurations effective.

■

After the ARP table size configuration, do not change cards or slots before you 
restart the system. Otherwise, the configuration above may fail to take effect.

■

After the ARP table size configuration, do not perform active/standby 
switchover before you restart the system. Otherwise, the configuration will not 
take effect even if you restart the system.

After performing the above configurations, you can execute the display 
command in any view to display the maximum numbers of ARP entries to verify 
the configurations.
