MIB draft: ifSpeed & ifPhysAddress

[John Rickard <[e-mail]>]

I think there may be a mistake in the description of the interface
table in the MIB draft.

From draft-ietf-ipatm-mib-01.txt:

From RFC 1695:

> 8.3.  Support of AAL5 by ifTable
> 
[...]
>           Object   Use for AAL5 CPCS layer entity
>           ======   ==============================

[...]
>           ifPhysAddress   An octet string of zero length.

Is ifSpeed for an IP over ATM Virtual Interface always going to be 0
and ifPhysAddress always empty, or is the rule in RFC 1695 expected to
be changed, or am I misunderstanding something, or is this a mistake
in the draft?

(According to RFC 1695, non-trivial values of ifSpeed and
ifPhysAddress, if available, are supplied at the layer below AAL5:
either the ATM cell layer or, in a switch, the proprietary virtual,
internal interface.)
