3 Refer to the Port Interface Table to assess the state of the traffic over the ports listed within the table
for the root and bridge and designated bridges.

Bridge Max Msg.
Age The Max Msg Age measures the age of received protocol
information recorded for a port, and to ensure the
information is discarded when it exceeds the value set for
the Maximum Message age timer. For information on
setting the Maximum Message Age. For information on
setting the Bridge Max Msg. Age, see
“Setting the LAN
Configuration for Mesh Networking Support” on page 523 .
Bridge Hello Time The Bridge Hello Time is the time between each bridge
protocol data unit sent. This time is equal to 2 seconds
(sec) by default, but can tuned between 1 and 10 sec. For
information on setting the Bridge Hello Time, see
“Setting
the LAN Configuration for Mesh Networking Support” on
page 523
. The 802.1d specification recommends the Hello
Time be set to a value less than half of the Max Message
age value.
Bridge Forward
Delay The Bridge Forward Delay value is the time spent in a
listening and learning state. This time is equal to 15 sec by
default, but you can tune the time to be between 4 and 30
sec. For information on setting the Bridge Forward Delay,
see
“Setting the LAN Configuration for Mesh Networking
Support” on page 523 .
Port ID Identifies the port from which the configuration message
was sent.
State Displays whether a bridge is forwarding traffic to other
members of the mesh network (over this port) or blocking
traffic. Each viable member of the mesh network must
forward traffic to extent the coverage area of the mesh
network.
Path Cost The root path cost is the distance (cost) from the sending
bridge to the root bridge.
Designated Root Displays the MAC address of the access point defined with
the lowest priority within the Mesh STP Configuration
screen.
Designated Bridge There is only one root bridge within each mesh network.
All other bridges are designated bridges that look to the
root bridge for several mesh network timeout values. For
information on root and bridge designations, see
“Setting
the LAN Configuration for Mesh Networking Support” on
page 523
.
Designated Port Each designated bridge must use a unique port. The value
listed represents the port used by each bridge listed within
the table to route traffic to other members of the mesh
network.
Designated Cost Displays the unique distance between each access point
MAC address listed in the Designated Bridge column and
the access point MAC address listed in the Designated
Root column.
