Setting and clearing the block duration for Web Authentication attempts

After users exceed the limit for Web Authentication attempts, you can specify how many seconds users must wait before the next cycle of Web Authentication begins. Enter the block duration command such as the following.

device(config-vlan-10-webauth)# block duration 4

Users cannot attempt Web Authentication during this time.

You can specify from 0 through 128000 seconds. The default is 90 seconds. Specifying 0 means that the MAC address is infinitely blocked.

To unblock the MAC address, wait until the block duration timer expires or enter a command such as the following.

Brocade(config-vlan-10-webauth)# clear webauth vlan 10 block-mac 000.000.1234

If you do not specify a MAC address, then all the entries for the specified VLAN will be cleared.
