xStack DGS-3400 Series Layer 2 Gigabit Managed Switch CLI Manual
Used to globally set the version of STP on the Switch.
config stp version [mstp | rstp | stp]
This command allows the user to choose the version of the
spanning tree to be implemented on the Switch.
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.
Only administrator-level users can issue this command.
Used to setup STP, RSTP and MSTP on the Switch.
config stp {maxage <value 6-40> | maxhops <value 1-20> | hellotime
<1-10> | forwarddelay <value 4-30> | txholdcount <value 1-10> | fbpdu
[enable | disable] | lbd [enable | disable] | lbd_recover_timer [<value 0>
| <value 60 -1000000>]}
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.
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 in STP, or by the
designated router in RSTP, thus stating that the Switch is still functioning. A
time between 1 and 10 seconds may be chosen, with a default setting of 2
seconds.
In MSTP, the spanning tree is configured by port and therefore,
the hellotime must be set using the configure stp ports command for
