Recently I have bought 8 Nos of Cisco 2960 switches (with 12.1 IOS)
In that I have tried 3 nos of switch ,configuring a port as a trunk port and connected to the core,it is working fine for a period of 1 hour time,after that the port got discoonected ,means lost the connectivity,it is with all 3 switch out of 5 switches,the remaining 5 switches I am yet to test it.
Where as if I configure the Cisco2950 it is working fine.
What could be the possible cause for this problem.?
How to solve this?
I need a help.
Thanks and Regards,
