Why disabling CDP and LLDP can be beneficial?
  • All Summit WM3000 Series Controllers
  • ExtremeWiNG Controllers
  • WirelessWiNG Controllers
  • ExtremeWiNG Access Points
  • WirelessWiNG Acess Points
  • WiNG v5.X Software
By default, each WiNG device runs CDP and LLDP protocols, which are designed to help mitigate some of the issues with the wired infrastructure or help negotiate PoE power allocation. However, it has been identified that in rare cases when customers have mixed switching infrastructure with a mix of managed and unmanaged switches OR switches that understand both CDP and LLDP and switches that understand LLDP only - having CDP enabled might cause increased CPU load on the adopting controller. In such cases it is highly recommended to disable both CDP and LLDP on all AP profiles. You should also disable CDP even if you run managed switches that might not understand CDP protocol, such as for example Extreme or HP switches.
