i have a switch (WS-C3560-8PC) Cisco IOS Software, C3560 Software (C3560-IPBASEK9-M), Version 12.2(50)SE3, RELEASE SOFTWARE (fc1) where I get no values when asking the spanning tree mib (188.8.131.52.184.108.40.206).

to determine which MAC Address table to look in for a forwarding
decision. To do this we require the switch to do...
