 GROUPID - numeric switching group identifier (1-4095)
 add|del - these commands add/delete specified interfaces to/from the
switching group. If "add" keyword is used and there is no switching group with
GROUPID identifier, it will be automatically created.
 IFNAME - network interface name which should be added or deleted from the
switching group.
 TAG. This option allows different manipulations with VLAN tags of the packet
when the packet is sent through this interface. The following options are
available:
» TAG is specified for the interfaces and its value is >0. That means that any
packet forwarded to the interface by the switch will be tagged with a VLAN
tag TAG. If the packet already had a tag, this tag will be retagged to TAG.
» TAG is not specified. This means that the packet stays unmodified.
» TAG is specified and its value is zero. This means that the packet sent
through this interface will be untagged if it was previously tagged or sent
without any changes if it was not tagged.
Example:
switch group 3 add rf5.0:10 eth0:0
In this example, all packets switched by group 3 will be tagged with VLAN TAG 10
when sending through rf5.0 interface and will be untagged when sent through
eth0 interface.
switch group GROUPID {repeater|trunk} {on|off}
This command turns on/off the modes for repeater or trunk.
In a repeater mode the group switches the packets by simple retranslation to any
other interfaces other than the one the packet was received from.
In trunk mode, the group switches all the packets received through eth*
interfaces in such a way that when packets are sent to rf* interfaces, these
packets are places in a group with a number corresponding to the packet's VLAN
TAG. When receiving the packet from rf* interfaces, trunk group sends these
packets to eth* interface tagging them with a switch group number this packet
was received from.
