Hi,
Setup:
6 manageable switches are connected in linear fashion with root brdige
at top . In the root bridge ,max-age ,hellotime and forward-delay is
configured as 6 ,1 and 4 .
Issue :
In the sixth bridge ,learned value of max-age,hello time and forward
delay is found as 6 ,1 and 4.But the role of the port connected to
switch 6 alone is switching between F/R (Root) and F/D (Designated )
We r using the source forge rstp source code for all 6 switches
From 802.1w standard,I calculated the rcvdinfowhile timer value for
the port connected to sixth switch as 1 (Calculation done from
updtRcvdInfoWhile()) .When port of switch 6 recieves BPDU for every
hello time (1 sec) port role switches to F/R and on expiry of
rcvdInfoWhile timer expiry ( 1 sec ) port role switches to F/D .
What do you think about it ?
