Disable of 802.3X PAUSE method of link-level flow control by default on IR800 routers

[j.kwek]

I am tasked to ensure that there is no pause frames on interfaces on IR829 router.

I have come across the article on this 802.3x link level flow control.

I am not able to find any CLI commands to disable flow control on the switch ports.  

Any supporting Doc that stated that the 802.3x link lievel flow control has been disable by default.

Pls advise.  Thanks.

Cisco 802.3X PAUSE Today

Hi -

Haven't been on this board for a while, so a big hello to my "friends" on here

Anyway, years ago, Cisco disabled the 802.3X PAUSE method of link-level flow control by default on - I think - all of its Ethernet switches because the shared memory and line rate forwarding capability were seen as sufficient to avoid input buffer overruns and thus precluded the need for flow control. What they did allow as a compromise was for an Ethernet switch port to receive a PAUSE frame and - I think - actually act on it, but not to send the PAUSE frame or pass it on.
