ELTEX MES23xx User Manual

MES53xx, MES33xx, MES23xx Ethernet Switch Series 87
Multiprocess STP mechanism is destined for creating independent trees of STP/RSTP/MSTP on the
device ports. Status changes of a individual tree do not impact to the status of other trees that allows you
to increase network stability and reduce time of the rebuilding trees in case of breakdowns. You should
exclude the possibility of appearing the rings between ports-members of different trees. To service
isolated trees, a specific process is created for each tree in the system. The device ports of the tree are
matched with the process.

Table 5.71. Global configuration mode commands
Command
Value/Default value
Action
spanning-tree
-/enabled
Enable STP on the switch.
no spanning-tree
Disable STP on the switch.
spanning-tree mode {stp |
rstp | mst}
-/RSTP
Set STP operation mode.
- stp—IEEE 802.1D Spanning Tree Protocol;
- rstp—IEEE 802.1W Rapid Spanning Tree Protocol;
- mst—IEEE 802.1S Multiple Spanning Tree Protocol.
no spanning-tree mode
Set the default value.
spanning-tree forward-time
seconds
seconds: (4..30)/15
seconds
Set the time interval for listening and learning states before
switching to the forwarding mode.
no spanning-tree

Set the default value.
spanning-tree hello-time
seconds
seconds: (1..10)/2
seconds
Set the interval for broadcasting 'Hello' messages to the
communicating switches.
no spanning-tree hello-time
Set the default value.
spanning-tree

-/denied
Enable protection that disables any interface when a BPDU
packet is received.
no spanning-tree

Disable protection that disables the interface when a BPDU
packet is received.
spanning-tree max-age
seconds
seconds: (6..40)/20
seconds
Set the lifetime of the STP spanning tree.
no spanning-tree max-age
Set the default value.
spanning-tree priority
prior_val
prior_val:
(0..61440)/32768
Set the priority of the STP spanning tree.
Priority value must be divisible by 4096.
no spanning-tree priority
Set the default value.
spanning-tree pathcost
method {long | short}
-/short
Set the method for defining the path cost.
- long – cost value in the range 1..200000000;
- short – cost value in the range 1..65535.
no spanning-tree pathcost
method
Set the default value.
spanning-tree bpdu
{filtering | flooding}
-/flooding
Set the BPDU packet processing mode by the interface on
which STP is disabled.
- filtering – BPDU packets are filtered on the interface on
which STP is disabled;
- flooding – untagged BPDU packets are transmitted and
tagged packets are filtered on the interface on which STP is
disabled.
no spanning-tree bpdu
Set the default value.
