I have a 2960 and a 2811 with a hwic card I have one port set as 100 meg and another port set at 10 meg. Both are set to access mode. i need one port for failover (10 meg) . I can't do etherchannel on the hwic. How do I prevent a loop when I connect my second connection. While having both connections up. Should I use bpdu guard? the goal is to have one port fail over if the 100 meg goes down. And I'm currently running ospf so it should take the faster connection.
