Hi,
Can the experts please check I’ve got my switch configuration correct? Appreciate your feedback :)

Configure SPAN port - source port 1/0/1 SPAN traffic to destination port 1/0/2
monitor session 1 source Gigabitethernet 1/0/1
monitor session 1 destination Gigabitethernet 1/0/2

To remove all SPAN sessions
no monitor session all

Configure an Ether Channel between 2960-S Switch & Dell server on ports 1/0/3 & 1/0/4 to allow the server 2Gbps bandwidth to/from the switch.
Configure the port for access mode not a trunk port
Assign ports to channel-group 1 and enable LACP mode – active negotiating state
Configure the EtherChannel load-balancing method as source MAC address. All the PCs will have a different source MAC address so this should balance the load best?
Do I need to assign the switch port to a VLAN using switchport access vlan 1? I have no VLANs configured so all ports are in VLAN1 by default.

interface GigabitEthernet 1/0/3
switchport mode access
channel-group 1 mode active

interface GigabitEthernet 1/0/4
switchport mode access
channel-group 1 mode active

Looks fine. You do not need to assign the channel group or the ports to a specific vlan. Without specifying, it will use vlan 1 by default anyway.

You may want to try it like this:

monitor session 1 source Gigabitethernet 1/0/1 both
monitor session 1 destination Gigabitethernet 1/0/2 encapsulation replicate

Your etherchannel config looks correct

Thanks for your comments,

monitor session 1 source Gigabitethernet 1/0/1 both
- defaults to "both" anyway I think.

monitor session 1 destination Gigabitethernet 1/0/2 encapsulation replicate
- thanks for pointing out these options I will read up on them and decide whether we need to use them

Thanks again for taking the time to review my config :)
Cheers
