A set of managed objects for optimizing access to bridging related data from RFC 1493. This MIB is modeled after portions of RFC 1493, adding VLAN ID based indexing and bitmapped encoding of frequently accessed data.
VlanIndexThe VLAN-id of a VLAN on ISL or 802.1q trunks.
Modification of default parameters is allowed. Implementations are allowed to restrict the range of VLANs.
For entities support up to 1024 VLANS. VLANs above 1000 are reserved for default VLANs and future use. Modification of default parameters is allowed. Creation or deletion of VLANs above 1000 is not allowed.
For a new object which needs the vlan-id of a VLAN as its SYNTAX, it is suggested to import VlanIndex from Q-BRIDGE-MIB instead of importing this TC here in CISCO-VTP-MIB. (0..4095) · Integer32
The VLAN-id of this VLAN on ISL or 802.1q trunks.

OCTET STRING SIZE (0..128)
An indication of which ports are forwarding by spanning tree for the specified VLAN. The octet string contains one bit per port on the bridge for the specified VLAN.
Each octet within the value of this object specifies a set of eight ports, with the first octet specifying ports 1 through 8, the second octet specifying ports 9 through 16, etc. Within each octet, the most significant bit represents the lowest numbered port, and the least significant bit represents the highest numbered port.
The bit value interpretation is related to RFC 1493 dot1dStpPortState values is as follows: 1 = forwarding 0 = disabled, blocking, listening, learning, broken, or nonexistent

1.3.6.1.4.1.9.9.56.1.1.1.1.3
CiscoPortListEach octet within this value specifies a set of eight ports. The object defined by this textual convention can specify a port range of 2k ports in its description. Example: 1 - 2048, 2049 - 4096, etc. The first octet represents the first 8 ports of the range of ports specified by the object, the second octet represents the next 8 ports, etc. When a port range is not specified, a default port range of '1 - 2048' is assumed.
Within each octet, the most significant bit represents the lowest numbered port, and the least significant bit represents the highest numbered port. Thus, each port of the bridge is represented by a single bit within the value of this object. If that bit has a value of '1' then that port is included in the set of ports; the port is not included if its bit has a value of '0'.
Note that if the length of this string is less than 256 octets, any 'missing' octets are assumed to contain the value zero. An NMS may omit any zero-valued octets from the end of this string in order to reduce SetPDU size, and the agent may also omit zero-valued trailing octets, to reduce the size of GetResponse PDUs. SIZE (0..256) · OCTET STRING
An indication of which ports are forwarding by spanning tree for the specified VLAN. The octet string contains one bit per port on the bridge for the specified VLAN. This object has STP status information of up to 2k ports with the port number from 1 to 2048.
Each octet within the value of this object specifies a set of eight ports, with the first octet specifying ports 1 through 8, the second octet specifying ports 9 through 16, etc. Within each octet, the most significant bit represents the lowest numbered port, and the least significant bit represents the highest numbered port.
The bit value interpretation is related to RFC 1493 dot1dStpPortState values is as follows: 1 = forwarding 0 = disabled, blocking, listening, learning, broken, or nonexistent.
