Unblocking a currently blocked host

A hostblocked by connection-rate filtering remains blocked until explicitly unblocked by one of the following methods:
  • Using the connection-rate-filter unblock command, see Listing currently-blocked hosts.

  • Rebooting the switch.

  • Disabling connection-rate filtering using the no connection-rate-filter command.

  • Deleting a VLAN removes blocks on any hosts on that VLAN.


Changing a port setting from block to throttle, notify-only, or to no filter connection-rate, does not unblock a currently blocked host. Similarly, applying a connection-rate ACL does not unblock a currently blocked host. See the above list for the correct methods to use to unblock a host.
