Congure Spanning Tree
System > Spanning Tree Sengs
The TEW-821DAP is designed for end point access as well as backbone connecon. To
avoid network looping, you can enable 802.1d spanning tree protocol.
To congure the spanning tree, do the following:
1 Log into your access point management page (refer to “Log in to Management Page”
on page 10).
2 Click System > Spanning Tree Sengs.

3 Modify any of the following Spanning Tree Sengs elds:
• Spanning Tree Status: Enable or disable 802.1d spanning tree protocol to avoid
network looping.
• Bridge Hello Time: The me between each bridge protocol data unit (BPDU).
Default: 2 sec.
• Bridge Max Age: Maximum me a BPDU kept in bridge. Default: 20 sec.
• Bridge Forward Delay: The me to be spent in listen and learning state. Default: 4
sec.
• Priority: Priority number for root bridge selecon. (MAC number is listed on
Status > Main menu).
4 Click Apply to save the spanning tree sengs or Cancel to discard the changes.
Enable Band Steering
System > Band Steer
In the oce, the 2.4GHz is always crowded than 5GHz. There are fewer non-overlapping
channels and more legacy devices in 2.4GHz compare to the 5GHz band. The TEW-
753DAP is equipped with 2.4GHz and 5GHz wireless interfaces. When your client device
can work on both 2.4GHz and 5GHz wireless, Band Steer will choose 5GHz as primary
band over 2.4GHz. Trac will mainly stays on 5GHz in stead of 2.4GHz. To setup band
steer, you have to setup the same SSIDs on both the 2.4GHz and the 5GHz interfaces.
To enable Band Steering, do the following:
1 Log into your access point management page (refer to “Log in to Management Page”
on page 10).
2 Click System > Band Steer.

3 Check Enable opon to allow band steering.
4 Click Save to save the seng or Cancel to discard the changes.
