Usage Guidelines

Usage Scenario

If the number of ARP entries that the device learns has reached the upper limit, it will cause some users unable to use the network normally, you can run this command to view the maximum number of ARP entries that each interface can learn and the number of ARP entries that each interface has learned.

Precautions

If you use this command on a Layer 2 or Layer 3 interface, both the maximum number of ARP entries that the Layer 2 or Layer 3 interface can learn and the number of ARP entries that the device has learnt are displayed.

Example

The actual command output varies according to the device. The command output here is only an example.

# View information about ARP entry learning on the device.
