Protocol Filters. This filter type enables the switch to restrict traffic of a
particular protocol type to a specific destination port or ports on the switch
(or to be dropped for all ports on the switch). Filtered protocol types include:
N o t e
The switch provides filtering only for Ethernet and 802.3 format packets.
Source Port Filters. This filter type enables the switch to restrict traffic
from all end nodes on the indicated source port to specific destination ports
(or to be dropped for all destination ports on the switch). If VLANs are
configured, the destination port must be in the same VLAN as the source port.
N o t e
If more than one VLAN is configured, then the set of destination ports (Dest
Port parameter) can consist of only the destination ports that are in the same
VLAN as the source port.
Source MAC Filters. This filter type enables the switch to specify the port
through which a node having a specified (source) MAC address can send
traffic. Only ports that are selected are allowed to send and receive traffic for
the specified node. For additional security, if traffic from the source MAC
address appears on any port other than the selected one, the traffic from that
source will be dropped and the Security LED on the front of the switch begins
flashing. (To clear the Security LED, use the Advanced Command ClearLED
command.)
