Virus Throttling (Connection-Rate Filtering)
Overview of Connection-Rate Filtering
Unblocking a Currently Blocked Host
A host blocked by connection-rate filtering remains blocked until explicitly
unblocked by one of the following methods:
â– Using the connection-rate-filter unblock command (page 3-16).
â– Rebooting the switch.
â– Disabling connection-rate filtering using the no connection-rate-filter
command.
â– Deleting a VLAN removes blocks on any hosts on that VLAN.
Note Changing a port setting from block to throttle, notify-only, or to no filter connec-
tion-rate, does not unblock a currently blocked host. Similarly, applying a
connection-rate ACL will not unblock a currently blocked host. Refer to the
above list for the correct methods to use to unblock a host.
