Bridge Filters

3.DESTINATION MAC-address DISCARD < distribution list >

This filter allows you to discard MAC frames addressed to the specified MAC address. When the specified MAC address appears in the destination address field of the MAC frame, the frame will NOT be forwarded as specified in the distribution list. If no distribution list is specified, the frame will not be forwarded.

4.DESTINATION MAC-address CONNECT< distribution list >

This filter allows you to connect MAC frames addressed to the specified MAC address. When the specified MAC address appears in the destination address field of the MAC frame, the frame will be forwarded as specified in the distribution list.

5.PROTOCOL protocol-Id DISCARD < distribution list >

This filter allows you to discard packets based on the Ethernet type field or the corresponding

802.3LSAP field. You specify the protocol Id that is to be discarded. The filtering mechanism will determine if the packet is Ethernet format or 802.3 format. The Ethernet type or LSAP field will be checked based on packet format. See the section titled "Protocol Definitions" for more information.

6.PROTOCOL protocol-Id CONNECT< distribution list >

This filter allows you to connect packets based on the Ethernet type field or the corresponding

802.3LSAP field. You specify the protocol Id that is to be connected. The filtering mechanism will determine if the packet is Ethernet format or 802.3 format. The Ethernet type or LSAP field will be checked based on packet format. See the section titled “Protocol Definitions” for more information.

7.PACKET OFFSET dd MASK xxxxxxxxxxxx VALUE xxxxxxxxxxxx DISCARD <distribution- list>

This filter allows you to discard packets based on packet data outside the source and destination MAC addresses or protocol Id. For example, you may wish to filter packets based on IP address information. You would then specify the offset (dd) into the MAC frame where the filter comparison is to begin. The mask data indicates which bits within the frame data are significant and will be compared to the value. The frame data is logically “anded” with the mask, and then compared to the specified value. The value field must be a subset of the mask field. That is, the value field logically “anded” with the mask field must equal the value field. The value and mask fields must have equal lengths.

8.PACKET OFFSET dd MASK xxxxxxxxxxxx VALUE xxxxxxxxxxxx CONNECT <distribution- list>

This filter allows you to connect packets based on packet data outside the source and destination MAC addresses or protocol Id. For example, you may wish to filter packets based on IP address information. You would then specify the offset (dd) into the MAC frame where the filter comparison is to begin. The mask data indicates which bits within the frame data are significant and will be compared to the value. The frame data is logically “anded” with the mask, and then compared to the specified value. The value field must be a subset of the mask field. That is, the value field logically “anded” with the mask field must equal the value field. The value and mask fields must have equal lengths.
