slot slot-number: Specifies the maximum number of dynamic ARP entries for the interface card specified

Usage guidelines

A device can dynamically learn ARP entries. To prevent a device from holding too many ARP entries, you

can set the maximum number of dynamic ARP entries that a device can learn. When the maximum

number is reached, the device stops learning ARP entries.

When the number argument is set to 0, the device is disabled from learning dynamic ARP entries.

Examples

# Specify the interface card in slot 1 to learn up to 64 dynamic ARP entries.
