The reset arp slot command clears the Address Resolution Protocol (ARP) entries learned on a specified board in an ARP table.
| Parameter | Description | Value |
|---|---|---|
| slot-id |
Clears ARP entries learned on a specified board. If slot-id specifies an interface board, all dynamic ARP entries learned on the interface board; Others are cleared all ARP entries. |
The value is a string of 1 to 23 case-sensitive characters, spaces not supported. |
Usage Scenario
If an unauthorized user sends a large number of ARP messages to a device, the device learns a large number of ARP entries in a short period of time, causing a buffer overflow. As a result, users may fail to access the network. To resolve the problem, run the reset arp command to delete invalid ARP entries so that new ARP entries can be created to allow authorized user access.
Prerequisites
ARP entries exist on a device.
The board specified by slot slot-id exists if this parameter is configured.Configuration Impact
After an ARP entry is cleared, the mapping between the IP and MAC addresses in the entry is cleared. As a result, users may fail to access the network, and services may be interrupted.
