[Cyrus Dulla Tam]

i have the design at the attachment and need help for redundancy.is it ok if make a port for the reundancy to be static LACP trunk going to the 3400cl failover switch for each of the 7 3400cl?the rest of the backbone connection are all trunks.i wanted it to become adaptive just incase the main connection to the 6410cl fails.....would it affect the inter-vlan communication if the fails?vlans exists in each of the 3400cl...thanx in advance....
