7.6.11.6 FORWARD-DELAY
Configures the time interval that goes by before there is a change in the state of a port (where the bridge has been
selected as the Spanning Tree root bridge). Admissible values range from 4 to 30 seconds. Default is 15 seconds.
Example:
ethernet0/0 switch config>stp 1 forward-delay 30
ethernet0/0 switch config>
Note
When configuring this parameter, ensure the following condition is fulfilled:
2 * (Bridge Forward Delay - 1 second) > Bridge Maximum Age
Configures the maximum time period during which the information received in the Spanning Tree protocol is valid.
Admissible values range from 6 to 40 seconds. Default is 20 seconds.
Example:
ethernet0/0 switch config>stp 2 max-age 13
ethernet0/0 switch config>
Note
When configuring this parameter, ensure the following conditions are fulfilled:
2 * (Bridge Forward Delay - 1 second) > Bridge Maximum Age
Bridge Maximum Age > 2 * (Bridge Hello Time + 1 second)
The Bridge Hello Time value is not configurable. It is set to 2 seconds.
7.6.11.7 PROTOCOL-VERSION
Configures the Spanning Tree protocol version running in the device.
Syntax:
ethernet
X/X
switch config>stp <instance> protocol-version
stp-compatibility
STP Compatibility Mode
rstp-normal-operation
RSTP Normal Operation
stp-compatibility
Device executes the old Spanning Tree protocol defined in the 802.1D-1998
standard. Spanning Tree BPDUs are used and RSTP (Rapid Spanning Tree Pro-
tocol) frames are not sent.
rstp-normal-operation
Device executes the Rapid Spanning Tree protocol. This protocol is an upgrade of
the quicker convergence Spanning Tree. This is done by default.
Example:
ethernet0/0 switch config>stp 1 protocol-version stp-compatibility
ethernet0/0 switch config>
7.6.11.8 TX-HOLD-COUNT
Maximum number of BPDUs sent through a port in one second. Admissible values range from 1 to 10. Default is 6
BPDUs.
Example:
ethernet0/0 switch config>stp 2 tx-hold-count 4
ethernet0/0 switch config>
7.6.12 EXIT
Exits the switch configuration menu.
