For the Link Aggregation, first you would need to create the port-channel:

(config)# interface port-channel 1

Then you would add the ports to the channel-group:

(config)# interface ethernet 1/1
(config-if)# channel-group 1
(config-if)# interface eth 1/2
(config-if)# channel-group 1

Then you would tag the VLANs on the port-channel:

(config)# interface port-channel 1
(config-if)# switchport allowed vlan add 1001-1005 tagged

thanks !

but is it correct ?

5224#conf
5224(config)# interface port-channel 1
5224(config-if)#switchport allowed vlan add 1001-1005 tagged
VLAN1001 is not exist
VLAN1002 is not exist
VLAN1003 is not exist
VLAN1004 is not exist
VLAN1005 is not exist
5224(config-if)#exit
5224(config)#

It looks like you have not created the VLANs on the switch. You need to use the "vlan database" command to add the VLANs to the database. See the following link to the VLAN section of the online CLI Guide for more information:

hi

I read this documentation, but I'm not sure, how it should work.

do you think it will be correct, before I do something wrong ?

5224(config)#vlan database
5224(config-vlan)#vlan 1001-1005 name TRUNK media ethernet
5224(config-vlan)#exit
5224(config)# interface port-channel 1
5224(config-if)#switchport allowed vlan add 1001-1005 tagged

You cannot create multiple VLANs with the same command and give them the same name. You would need to add each VLAN one at a time and give them each a unique name.
