Hi Tom,

Thank you for the comments.
<tp>

Med

As you may have surmised, I am working my way through the I-D but do not have a 
view yet of how long it will take so would not suggest waiting but rather, if 
you let me know what your deadline is for preparing a new version, as Adrian 
suggests, then I will send you my comments so far at that time.

In addition to my previous remarks, I note that two import in 8.3 lack YANG 
reference clauses.

Tom Petch 


Please see inline.

Cheers,
Med

[Med] Will check and fix as appropriate.

>
> 802.1ah is referenced but not in I-D References
[Med] Indeed. Fixed.

 802.3ah
[Med] Fixed.

ditto 802.1ag

[Med] This one is already referenced as IEEE-802-1ag.

> Amendment 5 looks like a separate document warranting a separate reference

[Med] As you know 802.1p is not a separate standard. Referenced 802.1Q in the 
text instead.

[Med] This is a typo. This should be "Base Pseudowire L2 encapsulation type"

> ccm-priority-type
> what is high what low?

[Med] Added the following to the description:

"A larger value indicates a higher priority."

>

[Med] Updated to "Maintenance Entity Group End Point (MEP)".

>
> leaf split-horizon-filtering
> what does true mean?

[Med] Made this change:

OLD:
          "Controls split-horizon filtering.

           In order to achieve split-horizon filtering, every
           Broadcast, unknown unicast, or multicast (BUM)
           packet originating from a non-DF PE is encapsulated
           with an MPLS label that identifies the origin ES.";

NEW:
          "Controls split-horizon filtering. It is enabled
           when set to 'true'.

           In order to achieve split-horizon filtering, every
           Broadcast, unknown unicast, or multicast (BUM)
           packet originating from a non-DF PE is encapsulated
           with an MPLS label that identifies the origin ES.";

>
> leaf ccm-interval
> no units

[Med] Added "milliseconds". Thanks.

>
> leaf ccm-holdtime
> no units

[Med] Added "milliseconds".

>
> leaf duplicate-ip-detection-interval
> no units
>
> leaf duplicate-ip-detection-interval
> no units

[Med] updated to indicate "seconds".
