Potential issues with bindings

  • When dynamic IP lockdown enabled, and a port or switch has the maximum number of bindings configured, the client DHCP request is dropped and the client does not receive an IP address through DHCP.

  • When dynamic IP lockdown is enabled and a port is configured with the maximum number of bindings, adding a static binding to the port fails.

  • When dynamic IP lockdown is enabled globally, the bindings for each port are written to hardware. If global dynamic IP lockdown is enabled and disabled several times, it is possible to run out of buffer space for additional bindings. The software delays adding the bindings to hardware until resources are available.
