Hello Kamal,
Actually for the Ether-Channel to come up, the configuration on both physical interfaces have to be identical, not the configuration between the physical interfaces and the port-channels. As a matter of fact, you can have "some" configuration under the physical interfaces and the rest, under the port-channel.
Good practice is to place the minimum configuration under the physical interfaces to have them join the port-channel group, and once joined, place all other configurations under the port-channel.
Another good practice, if you have a multi-vendor environement, you better not use LACP. Although LACP is a standards based protocol, different vendors may have slightly different implementations for it. Better go for static ether channel, as you have in your original post.
when you configure speed auto, you do not need to specify 10, 100 and 1000. These options are only there if you want to limit the speed negotiation. By default all of them wil be attempted.
Having said that, please see below the steps:
config t
!
default interface Gig1/0/23
default interface Gig1/0/24
!
interface GigabitEthernet1/0/23
channel-group 1 mode on
!
interface GigabitEthernet1/0/24
channel-group 1 mode on
!
Then make sure the interfaces have joined the Ether-Channel by entering the command:
show etherchannel summary
Then enter the rest of the commands under the port channel:
!
interface Port-channel1
switchport mode trunk
duplex full
speed auto
spanning-tree bpdufilter enable
!
