I do not see much (if any activity lately) :-(
But I have a question.
I see a VLAN ID represented in various forms:
- draft-ietf-bridge-ext-v2-01.txt
VlanId ::= TEXTUAL-CONVENTION
STATUS current
DESCRIPTION "A 12-bit VLAN ID used in the VLAN Tag header."
SYNTAX INTEGER (1..4094)
- somehwere I found:
dot1vProtocolPortGroupVid OBJECT-TYPE
SYNTAX INTEGER (1..4094)
MAX-ACCESS read-create
STATUS current
DESCRIPTION "The VID associated with a group of protocols for
each port."
REFERENCE "IEEE 802.1v clause 8.4.4, 12.10.1.2"
- In a DOCSIS document I find:
docsQosPktClassVlanId OBJECT-TYPE
SYNTAX Integer32 (0..4095)
MAX-ACCESS read-only
STATUS current
- In the framework PIB (draft-ietf-rap-frameworkpib-09.txt) I find:
frwk802FilterVlanId OBJECT-TYPE
SYNTAX Integer32 (-1 | 1..4094)
STATUS current
DESCRIPTION
"The VLAN ID (VID) that uniquely identifies a VLAN
within the device. This VLAN may be known or unknown
(i.e., traffic associated with this VID has not yet
been seen by the device) at the time this entry
is instantiated.
Setting the frwk802FilterVlanId object to -1 indicates that
VLAN data should not be considered during traffic
classification."
- In rfc2613 I find:
smonVlanIdStatsId OBJECT-TYPE
SYNTAX Integer32 (1..4094)
MAX-ACCESS not-accessible
STATUS current
DESCRIPTION
"The unique identifier of the VLAN monitored for
this specific statistics collection.
Tagged packets match the VID for the range between 1 and 4094.
An external RMON probe MAY detect VID=0 on an Inter Switch
Link, in which case the packet belongs to a VLAN determined by
the PVID of the ingress port. The VLAN to which such a packet
belongs can be determined only by a RMON probe internal to the
switch."
REFERENCE
"Draft Standard for Virtual Bridged Local Area Networks,
P802.1Q/D10, chapter 3.13"
- In RFC2674 I find:
VlanIndex ::= TEXTUAL-CONVENTION
STATUS current
DESCRIPTION
"A value used to index per-VLAN tables: values of 0 and
4095 are not permitted; if the value is between 1 and
4094 inclusive, it represents an IEEE 802.1Q VLAN-ID with
global scope within a given bridged domain (see VlanId
textual convention). If the value is greater than 4095
then it represents a VLAN with scope local to the
particular agent, i.e. one without a global VLAN-ID
assigned to it. Such VLANs are outside the scope of
IEEE 802.1Q but it is convenient to be able to manage them
in the same way using this MIB."
SYNTAX Unsigned32
- IN RFC2674 I also find
VlanId ::= TEXTUAL-CONVENTION
STATUS current
DESCRIPTION
"A 12-bit VLAN ID used in the VLAN Tag header."
SYNTAX INTEGER (1..4094)
Not sure I found all occurances.
So my question is: what is the CORRECT spec, and could we try
to define one (or a few) TC(s) that everyone else can IMPORT
and use.
