You have make sure that the Alcatel switch supports the LACP protocol. The LACP protocol is a supporting protocol to establish Etherchannel bundles and verify that the ports that are about to be bundled together are indeed eligible for bundling (for example, they all connect to the same neighboring device, they have the same operational characteristics and so on). You could also proceed without using any support protocol but I would not recommend that personally.
The way to create a LACP-controlled Etherchannel on a Cisco switch is to issue the following commands:
interface range fa0/1 - 4 shutdown [ ... All config that should be the same like access/trunk etc. ... ] channel-group 1 mode active no shutdown
The 'active' keyword in the example makes sure that the Etherchannel will be created as LACP-controlled Etherchannel. After these commands are entered, a Port-channel1 interface will be created that represent the Etherchannel bundle. The 'shutdown' and 'no shutdown' commands are optional but in various occasions, it has proved to be a best practice when creating Etherchannel bundles. I would suggest to shutdown all the ports, configure the LACP and related parameters and then bring the ports back up again.
