Hi 16again,
Any other situation that can show the same STP effects without physical unplugging cables?
With counters, what can you see?. For example in this case for X port blocked by STP
Totals (Since boot or last clear) :
Bytes Rx : 2,948,646,096 Bytes Tx : 1,937,188,467
Unicast Rx : 3,501,949,778 Unicast Tx : 2,725,757,392
Bcast/Mcast Rx : 2,407,356 Bcast/Mcast Tx : 96,320,597
Errors (Since boot or last clear) :
FCS Rx : 1 Drops Tx : 34,918
Alignment Rx : 0 Collisions Tx : 0
Runts Rx : 0 Late Colln Tx : 0
Giants Rx : 0 Excessive Colln : 0
Total Rx Errors : 1 Deferred Tx : 0
Others (Since boot or last clear) :
Discard Rx : 0 Out Queue Len : 0
Unknown Protos : 0
Rates (5 minute weighted average) :
Total Rx (bps) : 0 Total Tx (bps) : 0
Unicast Rx (Pkts/sec) : 0 Unicast Tx (Pkts/sec) : 0
B/Mcast Rx (Pkts/sec) : 0 B/Mcast Tx (Pkts/sec) : 0
Utilization Rx : 0 % Utilization Tx : 0 %
Thanks in advance.
