Hello,
Thank you in advance for any info you can provide. An external company configured a router with a two port ether-channel so one cable goes to switch 1 and the other goes to switch 2. If I plug in both cables the network comes to a halt. Should I stack the two switches instead of using trunks? Maybe I didn't configure the trunk properly.
Servers and five other Cisco 2960-S switches have a connection to both switches for redundancy.
