Etherchannel & Backup Interface

hosseinlotfi 2 posts	30 Dec 2012 at 6:33 a.m. UTC hi every body .. i have a layer 3 etherchannel with 2 port on a 3560 switch and the other side of channel is the vlan interface of a layer 2 switch with 2 access interface and its working well ! so i wanna send all traffic on the first link of channel and when it goes down , all traffic dynamically send over the second link of that channel , because the second one is the worst link ! i think the "Backup Interface" may be a good solution ! can any body help me ? thank you all .... ;)

You could also set static routes using the exit interface with different admin costs. object tracking: http://www.cisco.com/en/US/docs/ios/12_2t/12_2t15/feature/guide/fthsrptk.html#wp1027177 static routes: ip route 1.1.1.0 255.255.255.0 g0/1 1 ip route 1.1.1.0 255.255.255.0 g0/2 200
