3.7.4 Rules Configuration Commands
Rules are used for the following purposes:
Selecting an appropriate switching group when packet is received through eth*
interface. Packet will be switched only by that group to which rules it fully
satisfies.
When packet is chosen by the switching group and group decides whether this
packet needs to be sent through one of the interfaces. The packet will only be
sent if it satisfies the rules of this interface.
The rules consist of rules list and a decision by default (deny/permit). Each rule
consists of a sequential number, condition and decision (deny/permit). While
going through the list, the switch checks whether a packet matches the rule. If it
matches the rule, the decision set for this rule is applied to the packet. Otherwise,
the list of rules is viewed further. Rules are taken according to their sequential
number in ascending manner. If a packet does not match to any rule, the default
decision for this group or interface is taken.
The condition might consist of one or several parameters which are checked with
the packet. Five packet parameters can be checked:
1 Source interface (iface)
2 Source MAC-address (src)
3 Destination MAC-address (dst)
4 VLAN tag (vlan)
5 Ethernet-level protocol number ( proto )
For each parameter a corresponding list of values should be specified. Moreover,
in the condition a PCAP expression may be present. This expression will be
considered as a "pseudo parameter" of the packet and is called match. Therefore,
the packet is considered to have matched the condition, if all its parameters
match to the corresponding acceptable values from the lists and/or the packet
satisfies to the expression of match type. One or more parameters might be
missing in a condition clause - in this case it will mean that packet satisfies to
that part of the condition which is missing. If the list of acceptable values is
