-
From the Configuration
menu, select Device
Configuration.
-
Toggle STP (Spanning Tree
Protocol) to ON.
-
Select the STP Mode:
- STP—The
initial version of this protocol uses a single tree without regard to
VLAN. After convergence (30-50 seconds), only the root bridge sends
configuration Bridge Protocol Data Units (BPDUs).
- RSTP (Rapid
STP)—Like STP, RSTP uses single tree without regard to
VLAN. After convergence (a few millisecond to 6 seconds), all switches
send BPDUs every 2 seconds.
- MSTP (Multiple
STP)—Multiple Spanning Tree Protocol (MSTP) can map a
group of VLANs into a single Multiple Spanning Tree instance (MSTI).
Configure the MSTP settings.
-
Select a Priority for STP
from the drop-down list.
-
Configure the STP Timers:
- Forward
Delay—This is the time the switch spends in the
listening and learning state. The default is 15 seconds, and the range
is 4 to 30 seconds.
- Max
Age—This is the maximum time period before a bridge port
saves configuration BPDU information. The default is 20 seconds, the
range is 6 and 40 seconds.
-
Select SAVE.
Continue configuring the Ethernet port.
