This chapter describes how to create and edit packet filters using the packet
filter language. This chapter also provides instructions for how to:
List, display, and delete currently defined filters
Load packet filter definitions created in an ASCII-based editor onto the
Switch 2200 system
Assign filters to ports on the system
Independently configurable packet filtering is provided for the various
packet processing paths on each Ethernet port of a Switch 2200. The packet
processing paths are defined in Table 12-1.
Table 12-1 Packet Processing Paths
Path Description
Transmit all All frames that are transmitted to the segment connected to the port
Transmit All multicast (including broadcast) frames that are transmitted to the
multicast segment connected to the port
Receive all All frames that are received by the port from the segment connected
to the port
Receive All multicast (including broadcast) frames that are received by the
multicast port from the segment connected to the port
When you create a packet filter, you can assign it to the transmit or the
receive path of each port, or to both paths.
For additional detailed explanations of packet filter concepts, see Chapter 7:
