DES-3526 / DES-3526DC Layer 2 Fast Ethernet Switch CLI Reference Manual
68
config stp version
Purpose
Used to globally set the version of STP on the Switch.
Syntax
config stp version [mstp | rstp | stp]
Description
This command allows the user to choose the version of the
spanning tree to be implemented on the Switch.
Parameters
mstp
– Selecting this parameter will set the Multiple Spanning
Tree Protocol (MSTP) globally on the Switch.
rstp
- Selecting this parameter will set the Rapid Spanning Tree
Protocol (RSTP) globally on the Switch.
stp
- Selecting this parameter will set the Spanning Tree Protocol
(STP) globally on the Switch.
Restrictions
Only administrator-level users can issue this command.
Example usage:
To set the Switch globally for the Multiple Spanning Tree Protocol(MSTP):
DES-3526:4#config stp version mstp
Command: config stp version mstp
Success.
DES-3526:4#
config stp
Purpose
Used to setup STP, RSTP and MSTP on the Switch.
Syntax
config stp {maxage <value 6-40> | maxhops <value 1-20> |
hellotime <value 1-10> | forwarddelay <value 4-30>|
txholdcount <value 1-10> | fbpdu [enable | disable] | lbd
[enable | disable] | lbd_recover_timer [0 | <value 60-1000000>]}
Description
This command is used to setup the Spanning Tree Protocol (STP)
for the entire Switch. All commands here will be implemented for
the STP version that is currently set on the Switch.
Parameters
maxage <value 6-40>
−
This value may be set to ensure that old
information does not endlessly circulate through redundant paths in
the network, preventing the effective propagation of the new
information. Set by the Root Bridge, this value will aid in
determining that the Switch has spanning tree configuration values
consistent with other devices on the bridged LAN. If the value ages
out and a BPDU has still not been received from the Root Bridge,
the Switch will start sending its own BPDU to all other switches for
permission to become the Root Bridge. If it turns out that your
switch has the lowest Bridge Identifier, it will become the Root
Bridge. The user may choose a time between 6 and 40 seconds.
The default value is 20.
maxhops <value 1-20>
- The number of hops between devices in a
spanning tree region before the BPDU (bridge protocol data unit)
packet sent by the Switch will be discarded. Each switch on the hop
count will reduce the hop count by one until the value reaches zero.
The Switch will then discard the BDPU packet and the information
held for the port will age out. The user may set a hop count from 1
to 20. The default is 20.
hellotime <value 1-10>
−
The user may set the time interval
between transmission of configuration messages by the root
device, thus stating that the Switch is still functioning. A time
