Licensing Requirements and Limitations for Deception

Licensing Requirements and Limitations for Deception

Involved Network Elements

The deception function needs to be used together with the Decoy.

Licensing Requirements

Deception is a basic feature of a switch and is not under license control.

Version Requirements

Only the S5720HI, S5730HI, and S6720HI running V200R013C00 and later versions support the deception function.

Feature Limitations

  • You are advised to deploy DecoySensors on access switches.
  • There must be reachable routes between switches and the Decoy.
  • If a firewall is deployed between switches and the Decoy, you need to enable UDP ports 11514 and 10514 on the firewall.
  • The following configurations must be performed on the switch. Otherwise, the deception function does not take effect.
    • VLANIF interfaces are configured to send ARP packets destined for other devices to the CPU using the undo arp optimized-passby enable command.
    • The optimized ARP reply function is disabled using the arp optimized-reply disable command.
    • At least one of the detection network segment and the bait network segment must be configured.
  • The switch can only detect scanning of IP addresses on the same network segment as the primary IP address of the VLANIF interface.
  • A switch cannot use the virtual IP address of a VRRP group or the IP address of the management network interface to connect to a Decoy.
  • A bait network segment cannot contain the device management address and any network segment ( Otherwise, the devices cannot be managed remotely.
  • To enable the Agile Controller-Campus to deliver associated policies to switches, configure the free mobility function on the switches and ensure that the switches can communicate with the Agile Controller-Campus.
