Network Access (MAC Address Authentication)
– 302 –
Command Usage
When using a bit mask to filter displayed MAC addresses, a 1 means “care” and a 0
means “don't care. For example, a MAC of 00-00-01-02-03-04 and mask FF-FF-FF-
00-00-00 would result in all MACs in the range 00-00-01-00-00-00 to 00-00-01-FF-
FF-FF to be displayed. All other MACs would be filtered out.
