Spanning Tree Configuration
Bridge configuration -
Values 2-4 take effect only if a given Bridge is Root:
1.
Bridge ID –
value from (0..61440)
;
this parameter and MAC address determine
whether a given Bridge is Root Bridge. Advantage is given to the combination of
Priority
and
Address
, which is numerically smaller;
2.
Hello Time (1 – 100 sec) –
time gap, between which the BPDU packets are being
sent;
3.
Max Age (6 – 40 sec) –
this parameter determines time period, during which the
received BPDU packets’ information is stored for a separate port;
4.
Forward Delay (4 – 30 sec) –
time period that determines time a separate port stays
in
Listening
and
Learning
conditions;
5.
Version –
allows to switch STP versions between STP, RSTP or MSTP;
6.
STP operation –
Enable or Disable STP operation;
7.
Change between MST instances configuration when MSTP operation mode is
enabled;
Root information
– displays the data only when STP/RSTP/MSTP is enabled:
8.
Regional Root ID –
displays the Bridge ID for
instance 0*
of current Root bridge;
9.
Regional Root Port –
currently selected root port for
instance 0*
is being shown;
10.
Root Path Cost –
displays the path cost port for
instance 0*
from current bridge to
root bridge;
11.
Hello Time –
displays the current hello time;
12.
Max Age –
displays the current max age;
13.
Forward Delay –
displays the current forward delay;
14.
Bridge ID –
displays the Bridge ID of current Root bridge;
15.
Root Port –
currently elected root port is being shown;
16.
Root Path Cost –
displays the path cost from current bridge to root bridge;
17.
P1..4 (LAN) –
