4.3 Interface Stack Group - (RFC 2863)
The interface stack group consists of an object containing information on the relationships
between the multiple sub-layers of network interfaces. In the GranDSLAM 3.0, the
interface stack group will be used to show the relationship between the multiple logical and
physical interfaces, if a physical interface exists.
The ifStackTable entries for the product is illustrated below, please refer to Table 1-6,
GranDSLAM 3.0 Interface List , for the exact number of interfaces of each class supported
in the current release:
* If the associated IMA interface is present
** If the associated SONET interface is present
4.3.1 “ifStackHigherLayer” Object (ifStackEntry 1)
This object provides the ifIndex corresponding to the higher sub-layer running on ‘top of’
the interface specified in ifStackLowerLayer.
*** If the associated ATM link is part of an IMA group
