i have 3548L2 switch connected to 7513 via fast ethernet. I am doing trunking between them. I had a problem earlier that i was gettting CRC and fast ethernet
expereincing errors messages on 3548 but we were able to fix it by changing trunking encapsulation from isl to dot1q. Now the problem is that I am receiving
a lot of runts from router. I have checked my 6509 connected to 7513 on different port fa 5/1/0 and i don't see runts but i do see few giants. My router interface
is clean. I am wondering why whould router generate so many runts. I don't see a whole lot of broadcast or multicast.
