Byte Offset: Text Field. Defines the location of the beginning of
VALUE as the number of bytes from the beginning of the frame. It
can be a number from 0 to 58.
For example, a byte offset of 12 lines up VALUE with the Ethernet
type field, as shown in Figure 3-9.

Action: Text Field (filter / pass). The action the filter set will
take with relevant packets. Enter filter to filter the packets, or
pass to forward the packets.
Apply Action to: Text Field (same / different). The set of
packets the bridge will take action upon. Ente r same to refer to
packets matching the bit pattern, or different to refer to the
packets not matching the bit pattern.
Set Ports: Text Field (+n / +n-n / -n / -n-n). The ports to which
the filter applies. The ports are numbered from 1 to 4 (4 refers to
the external port). An X under the port number means that the
filter applies to that port.
To include a port, enter +n, where n is the port number (for
example, +4 includes port 4).
To include a range of ports, enter +n-n, where n-n is the range
(for example, +2-4 includes ports 2 to 4).
To exclude a port, enter -n, where n is the port number (for
example, -4 excludes port 4).
To exclude a range of ports, enter -n-n, where n-n is the range
(for example, -2-4 excludes ports 2 to 4).
