Requested revision
Standard: | 802.1Q-2012 | Clause: | 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.
