last night i have experiance network probs, which i suspect it could be a network loop,we have 6509 as core 3750 as standby both running hsrp, 2950 is the switch were the users are connected, the connectivity lookz
this setting is running for the past 4 months with no issue. but suddenly sterday night file transfer has become very slow, so i jus disabled the uplink in 2950 which is connecting to 3750, file transfer has become normal. i didn't make any modification, i didn't get any log in the switch related to ip address conflict of the vlanz ip address.what might have cause the problems & how to check whether looping is there or not?
i noticed in recent days in the 6509 logging buffer that the uplink to 2950 trunk down & then up, that to once in a day, switch never restarted or cable is not plugged out, but i get this message. also i noticed that port channel is on in 6509 which is connecting to 2950, actually only one cable is connected to 2950, so will that also be the probs for getting the port down & up once in a day & also for the network slow, i really don't think so because of that, but also not sure
