The deception mac-address aging-time command configures the interval at which the switch sends an ARP broadcast packet.
The undo deception mac-address aging-time command restores the default interval at which the switch sends an ARP broadcast packet.
By default, the switch sends an ARP broadcast packet at an interval of 290 seconds.
Parameter | Description | Value |
---|---|---|
aging-time | Specifies the interval at which the switch sends an ARP broadcast packet. |
The value is an integer in the range from 10 to 1000000, in seconds. |
To perform spoofing on IP address scanning, the switch constructs a virtual MAC address and sends it to the scanning source. The scanning source then incorrectly considers that the IP address to be scanned is online, and the switch diverts subsequent traffic from the scanning source to a Decoy for attack detection. The Layer 2 switch records an ARP entry of the scanned IP address and virtual MAC address. To prevent packets destined for the scanned IP address from being broadcast on the network after the entry is aged out, the switch periodically sends an ARP broadcast packet that contains the mapping between the scanned IP address and the virtual MAC address to the Layer 2 switch. You can run the deception mac-address aging-time command to adjust the interval at which the switch sends an ARP broadcast packet.
