Here are the steps to configure the required port channel and VLAN settings on Switch A:

Enter Configuration Mode:

SwitchA# configure terminal

Create Port Channel 10:

SwitchA(config)# interface port-channel 10

SwitchA(config-if-po10)# switchport mode trunk

SwitchA(config-if-po10)# switchport trunk native vlan 1

SwitchA(config-if-po10)# switchport trunk allowed vlan 1,10

Assign Interfaces Eth 1/11 and Eth 1/12 to Port Channel 10:

SwitchA(config)# interface ethernet 1/11

SwitchA(config-if-eth1/11)# channel-group 10 mode active

SwitchA(config-if-eth1/11)# exit

SwitchA(config)# interface ethernet 1/12

SwitchA(config-if-eth1/12)# channel-group 10 mode active

SwitchA(config-if-eth1/12)# exit

Configure Interface Eth 1/1 for Server Connection:

SwitchA(config)# interface ethernet 1/1

SwitchA(config-if-eth1/1)# switchport mode trunk

SwitchA(config-if-eth1/1)# switchport trunk native vlan 1

SwitchA(config-if-eth1/1)# switchport trunk allowed vlan 1,10

SwitchA(config-if-eth1/1)# end

Save Configuration:

SwitchA# write memory

Comprehensive Detailed Step by Step Explanation with References:

Enter Configuration Mode:

Start by entering the global configuration mode to make changes to the switch configuration.

Create Port Channel 10:

Enter the port channel interface configuration mode using interface port-channel 10.

Set the port channel to trunk mode with switchport mode trunk.

Specify VLAN 1 as the native VLAN (untagged) using switchport trunk native vlan 1.

Allow VLANs 1 and 10 on the trunk with switchport trunk allowed vlan 1,10.

Assign Interfaces Eth 1/11 and Eth 1/12 to Port Channel 10:

Enter interface configuration mode for ethernet 1/11 and ethernet 1/12.

Assign each interface to port channel 10 using the channel-group 10 mode active command.

Exit the interface configuration mode.

Configure Interface Eth 1/1 for Server Connection:

Enter interface configuration mode for ethernet 1/1.

Set the interface to trunk mode with switchport mode trunk.

Specify VLAN 1 as the native VLAN using switchport trunk native vlan 1.

Allow VLANs 1 and 10 on the trunk with switchport trunk allowed vlan 1,10.

Exit the configuration mode.

Save Configuration:

Ensure the configuration is saved so it persists after a reboot using the write memory command.
