Having a strange issue here.. I replaced a stack member (2 members in a stack of Cisco 3750x). Both switches have a 10Gb card and I had a perfectly working LAG/etherchannel between to 10Gb ports.

After replacing a stack member the portchannel can't bundle due to flow-control mismatch. It says that flow-control is of on the interface of the new member but in the config it is clearly on, consistent with the config on the other interface and the portchannel. 

The error:
`%EC-5-CANNOT_BUNDLE2: Te1/1/2 is not compatible with Te2/1/2 and will be suspended (flow control receive of Te1/1/2 is off, Te2/1/2 is on) (ISCSI-MER2-1)`

sh run:

```
interface TenGigabitEthernet1/1/2
 flowcontrol receive on
 channel-protocol lacp
 channel-group 1 mode active
end

interface TenGigabitEthernet2/1/2
 flowcontrol receive on
 channel-protocol lacp
 channel-group 1 mode active
end

interface Port-channel1
 flowcontrol receive on
end

```

I want to try to add another port to the channel but not sure if this causes disruption on the portchannel? 

I could also try to disable flow control on the interfaces and on the port channel, but I need to now if this can be done during production?
