Hi...
Iwe have connected Cisco 3550 to cisco 3750 switch via two Metro Ethernet link each of 45 Mbps ..Etherchannel is created among them on both the switch.HSRP also configured for Failover . But The problem is that when one link fails ..the another link is not work..

Bldg 1..
1st Link = Bldg1 (CAT3550-Gi0/11) To Bldg2(CAT 3750 - Gi1/0/1 )

2nd Link = Bldg1 (CAT3550-Gi0/12) To Bldg2(CAT 3750 - Gi1/0/2 )

Both End EtherChannel Config is as bellow
!
interface Port-channel1
switchport trunk encapsulation dot1q
switchport mode trunk
!
interface GigabitEthernet0/11
channel-group 1 mode on
!
same for rest 3 trunk ports...

HSRP is configured in Vlan Interface only...

can anybody help me out ??

 
First off, why are you aggregating links for trunks?
Second, what backup is not taking place? A floating static route or HSRP? Please post a config of all devices involved...
