How do I allow more then one device on all ports of the 520 Switch. When I hook another switch to any port on the switch it will only allow one Mac address/ or device to that connections. How would I disable that. Any step by step instructions would be great.
Sounds like mac based port security is enabled. I've never worked on the Catalyst 520 but there must be a config section under security. However, be very careful connecting switches to other switches. An Ethernet loop can ruin your day.
