10 - 2 Ethernet or Token Ring Bridge
Overview
Client nodes and repeater Bridges request to be associated with a parent
Bridge so the parent will forward data frames. This exchange of radio
packets passes back and forth information such as a node’s address,
device, association type, and ASCII name. This information is entered
into the Bridge’s association table along with the address of the parent
Bridge. Each Bridge maintains entries in its table for all nodes associ-
ated to it and all nodes associated to any repeater serving it. There may
be up to 2048 entries in the table.
A Bridge will accept an association from any node that requests it. The
operator may set up entries in the association table to control which
nodes are allowed to associate. See “Association Monitor Menu (Moni-
tor)”.
Using the information in the association table, the Bridge can perform a
variety of traffic-control functions in moving packets to their proper
destination on the infrastructure. When packets are received from the
Ethernet or Token Ring or radio network, the Bridge will look in its
table for the packet’s destination address and do one of the following:
n If the entry shows the radio node is associated to this unit, the
packet can be forwarded directly.
n If the entry indicates that the entry is associated to a repeater
serving this unit, the packet is forwarded to the repeater.
n If the address is not found, a root unit will forward the packet to the
wired LAN, while a repeater will forward the packet to its own
parent Bridge.
