Requested revision
Standard:802.1Q-2012Clause:17.7.6
Clause title:Definitions for the IEEE8021-MSTP MIB module
Rationale for revision
In MSTP, all VLANs are assigned to the CIST by default and users may 
assign VLANs to other MST instances.


The ieee8021MstpVlanV2Table read-only table maps VLANs to MST instances.

ieee8021MstpFidToMstiV2Table is read-writable, but it is indexed by 
filtering database (FID), rather than VLAN.


FID to VLAN allocation is done via ieee8021QBridgeVlanCurrentTable, 
which is a (partially) dynamic table.


A user cannot configure the VLANs to MST instances mapping, if the FID 
to VLAN mapping is created dynamically, or if a VLAN was not assigned an 
FID yet.
Proposed text
Change the MAX-ACCESS clause of ieee8021MstpVids0, ieee8021MstpVids1, 
ieee8021MstpVids2, ieee8021MstpVids3 (pages 729, 730) to read-create, 
and use them for VLAN-to-MST mapping, regardless of VLAN-to-FID mappings.


A similar solution is to change the MAX-ACCESS clause of 
ieee8021MstpVlanV2MstId to read-write, but this is inconvenient if you 
have to map a many VLANs, since ieee8021MstpVlanV2Table contains one row 
per VLAN.
