■
Priority — Sets the rule priority, which determines which rule is
matched to a packet on a first-match basis. The possible field values
are 1-2147483647.
■
Source MAC Address — Matches the source MAC address to which
packets are addressed to the rule.
■
Source Mask — Defines the source MAC Address wildcard mask.
Wildcards are used to mask all or part of a source MAC address.
Wildcard masks specify which bits are used and which are ignored. A
wildcard mask of FF:FF:FF:FF:FF:FF indicates that no bit is important. A
wildcard of 00.00.00.00.00.00.00 indicates that all bits are important.
For example, if the source MAC address is 00:AB:22:11:33:00 and the
wildcard mask is 00:00:00:00:00:FF, the first five bytes of the MAC are
used, while the last byte is ignored. For the source MAC address
00:AB:22:11:33:00, this wildcard mask matches all MAC addresses in
the range 00:AB:22:11:33:00 to 00:AB:22:11:33:FF.
■
Destination MAC Address — Matches the destination MAC address
to which packets are addressed to the rule.
■
Destination Mask — Defines the destination MAC Address wildcard
mask. Wildcards are used to mask all or part of a destination MAC
address. Wildcard masks specify which bits are used and which are
ignored. A wildcard mask of FF:FF:FF:FF:FF:FF indicates that no bit is
important. A wildcard mask of 00.00.00.00.00.00 indicates that all
bits are important. For example, if the destination MAC address is
00:AB:22:11:33:00 and the wildcard mask is 00:00:00:00:00:FF, the
first five bytes of the MAC are used, while the last byte is ignored. For
the destination MAC address 00:AB:22:11:33:00, this wildcard mask
matches all MAC addresses in the range 00:AB:22:11:33:00 to
00:AB:22:11:33:FF.
■
