CHAPTER 13: RAPID SPANNING TREE PROTOCOL
MULTILINK ML2400 ETHERNET COMMUNICATIONS SWITCH – INSTRUCTION MANUAL
• Status: Indicates whether STP or RSTP is enabled.
• Bridge Hello Time: When the switch is the root device, this is the time between
messages being transmitted. The value is from 1 to 10 seconds, with a default of 2.
• Bridge Forward Delay: Indicates the time duration the switch will wait from listening
to learning states and from learning to forwarding states. The value ranges from 4 to
30 seconds, with a default of 15.
• Bridge Max Age: This is the maximum time a message with STP information is allowed
by the switch before the switch discards the information and updates the address
table again. The value ranges from 6 to 40 seconds with a default 20.
• Hold Time: This is the minimum time period to elapse between the transmissions of
configuration BPDUs through a given LAN Port. At most one configuration BPDU shall
be transmitted in any hold time period. This parameter is a fixed parameter, with
values as specified in RSTP standard (3 seconds).
• Topology Change: A counter indicating the number of times topology has changed.
• Time since TC: Indicates time that has elapsed since the last topology change. Use
this in conjunction with uptime on the graphical display (screen shown after a
successful login) to find the frequency of the topology changes.
Click on Edit to make any changes.
On this screen, you can select and enable STP or RSTP.
Under protocol, select "Force to STP" if there are legacy or other
third party devices that do not support RSTP.
Otherwise it is recommended to enable "Normal RSTP".
