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.
7. Click Cancel to discard the changes made to the Mesh STP Configuration and return to
the LAN1 or LAN2 screen. Once the Mesh STP Configuration is defined, the AP-5131’s
radio can be configured for base and/or client bridge support.
9.2.2 Configuring a WLAN for Mesh Networking Support
Each AP-5131 comprising a particular mesh network is required to be a member of the same WLAN.
Therefore, each base bridge, client bridge or repeater within the mesh network must use the same
WLAN in order to share the same ESSID, radio designation, security policy, MU ACL and Quality of
Service policy. If intending to use the AP-5131 for mesh networking support, Symbol recommends
configuring at least one WLAN (of the 16 WLANs available) specifically for mesh networking support.
To define the attributes of the WLAN shared by the members of the mesh network:
1. Select Network Configuration -> Wireless from the AP-5131 menu tree.
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.
