Define the properties for the following parameters within the mesh network:
6
Click
OK
to return to either the LAN1 or LAN2 screen where updates to the Mesh STP
Configuration can be saved by clicking the
Apply
button.
Priority
Set the
Priority
as low as possible to force other devices
within the mesh network to defer to this client bridge as
the bridge defining the mesh configuration (commonly
referred to as the root). Extreme Networks recommends
assigning a Base Bridge AP with the lowest bridge priority
so it becomes the root in the STP. If a root already exists,
set the Bridge Priorities of new APs accordingly so the root
of the STP doesn't get altered. Each Access Point starts
with a default bridge priority of 63335.
Maximum Message
age
The
Maximum Message age
timer is used with the
Message Age timer. The Message Age timer is used to
measure the age of the 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.
Hello Time
The
Hello Time
is the time between each bridge protocol
data unit sent. This time is equal to 2 seconds (sec) by
default, but you can tune the time to be between 1 and 10
sec. If you drop the hello time from 2 sec to 1 sec, you
double the number of bridge protocol data units sent/
received by each bridge. The 802.1d specification
recommends the Hello Time be set to a value less than
half of the Max Message age value.
Forward Delay
The
Forward Delay
is the time spent in the 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. The
802.1d specification recommends the Forward Delay be
set to a value greater than half the Max Message age
timeout value.
Forwarding Table
Ageout
The Forwarding Table Parameter value defines the length
of time an entry will remain in the a bridge’s forwarding
table before being deleted due to lack of activity. If the
entry replenishments a destination generating continuous
traffic, this timeout value will never be invoked. However, if
the destination becomes idle, the timeout value represents
the length of time that must be exceeded before an entry
is deleted from the forwarding table.
