Cisco SPAN question

I know we can setup a catalyst 6509-E switch port as destination port to mirror a another switch port or etherchannel as source port.
But I am not sure if we can setup an etherchannel as destination port? The reason is the traffic to be monitored may exceed 1Gbps. If we can use etherchannel as destination port, we have 2 Gbps and will not have problem of packet drop.
For example,
monitor session 1 source interface port-channel 300
monitor session 1 destination interface port-channel20

If it does not work this way, I'd be appreciated if someone could help.

You can't set destination for SPAN to etherchannel.

Edit: Actually, Note: From Cisco IOS Software Release 12.2(33)SXH and later, PortChannel interface can be a destination port. Destination EtherChannels do not support the Port Aggregation Control Protocol (PAgP) or Link Aggregation Control Protocol (LACP) EtherChannel protocols; only the on mode is supported, with all EtherChannel protocol support disabled.

So I guess it can be but depends on the version.

Thanks SIM50. The version is 12.2(33)SXI. Is this how I should setup for 2 interfaces that to be destination port?

interface port-channel20
 switchport
 switchport trunk encapsulation dot1q
 switchport mode trunk
.
.
.
interface GigabitEthernet1/0/23
switchport
 switchport trunk encapsulation dot1q
 switchport mode trunk
 spanning-tree portfast edge
 spanning-tree guard root
channel-group 20
!
interface GigabitEthernet1/0/24
switchport
 switchport trunk encapsulation dot1q
 switchport mode trunk
 spanning-tree portfast edge
 spanning-tree guard root
channel-group 20

That should be it. Use "sh monitor session 1" to verify.
