Hi!

We have a RSPAN session configured with a GigabitEthernet as destination port. (1 Gbps). We have detected drops on this destination port, due to source interface traffic excess 1 Gbps.(10 Gbps interface)

We have look for any information about configure a Port-Channel with two ports on destination RSPAN session switch, and configure monitor session destination with two destination ports as:

int po15
switchport trunk encapsulation dot1q
switchport trunk native vlan 2
switchport trunk allowed vlan 905
switchport mode trunk
exit

int Gi0/14
channel-group 15 mode active
int Gi0/15
channel-group 15 mode active

monitor session 5 source remote vlan 905
monitor session 5 destination interface Gi0/14
monitor session 5 destination interface Gi0/15

What's the default behaviour of this configuration? 

A) RSPAN destination traffic will be load-balanced betweeen interfaces Gi0/14 and Gi0/15

B) RSPAN destination traffic will be the same on both interfaces Gi0/14 and Gi0/15, traffic will be copied to both interfaces.

Is there any way to acchive this load-balance betweeen destination interfaces to avoid destination interface (GigaEthernet) bandwith limits?
