MVTX2801
Data Sheet
Bit[7:6]
•
•
Security Enable (Default 00). The MVTX2801 checks the incoming data for one of the following
conditions:
If the source MAC address of the incoming packet is in the MAC table and is defined as secure
address but the ingress port is not the same as the port associated with the MAC address in
the MAC table.
•
A MAC address is defined as secure when its entry at MAC table has static status and bit 0 is
set to 1. MAC address bit 0 (the first bit transmitted) indicates whether the address is unicast
or multicast. As source addresses are always unicast bit 0 is not used (always 0). MVTX2801
uses this bit to define secure MAC addresses.
•
•
•
If the port is set as learning disable and the source MAC address of the incoming packet is not
defined in the MAC address table.
If the port is configured to filter untagged frames and an untagged frame arrives or if the port is
configured to filter tagged frames and a tagged frame arrives.
If one of these three conditions occurs, the packet will be handled according to one of the
following specified options:
- 00 - Disable port security
- 01 - Enable port security. Port will be disabled when security violation is detected
- 10 - N/A
- 11 - N/A
