How to turn flowcontrol on for Nexus 7K interfaces

Hi all,

Hopefully a simple question.

I am unable to set flow control to ON on our Nexus 7K - by default it is set to OFF:

Internal(config-if)# sh int e3/9

Ethernet3/9 is up

admin state is up, Dedicated Interface

  Belongs to Po10

  Hardware: 1000/10000 Ethernet, address: 8478.ac1a.e08c (bia 8478.ac1a.e08c)

  Description: nidcaixvio01 Eth0 (IBM AIX UCS2)

  MTU 1500 bytes, BW 10000000 Kbit, DLY 10 usec

  reliability 255/255, txload 1/255, rxload 1/255

  Encapsulation ARPA, medium is broadcast

  Port mode is trunk

  full-duplex, 10 Gb/s, media type is 10G

  Beacon is turned off

  Auto-Negotiation is turned on

  Input flow-control is off, output flow-control is off

Internal(config-if)# flowcontrol ?

                                           ^

% Invalid command at '^' marker.

However, the config guide and cmd ref clearly show these commands:

BEFORE YOU BEGIN

Make sure that the remote port has the corresponding setting for the flow control that you need. If you

want the local port to send flow-control pause frames, make sure that the remote port has a receive

parameter set to on or desired. If you want the local port to receive flow-control frames, make sure that

the remote port has a send parameter set to on or desired. If you do not want to use flow control, you can

set the remote port’s send and receive parameters to off.

SUMMARY STEPS

1. configure terminal

2. interface ethernet slot/port

3. flowcontrol {send | receive} {desired | on | off}

4. (Optional) show interface ethernet slot/port

5. (Optional) show interface flowcontrol

6. exit

7. (Optional) copy running-config startup-config

Any suggestions?

Thanks in advance.

Sorry, the interface was part of a port channel - therefore it wasn't allowing that command. I could execute it on the port channel interface
