REVISION "200104101200Z" -- 10 April 2001 12:00:00 GMT DESCRIPTION "Initial version." ::= { mplsMIB 1 } -- mplsMIB To Be Assigned by IANA mplsMIB OBJECT IDENTIFIER ::= { transmission xxx } -- To be assigned by IANA -- Since mpls is ifType: 166 -- we recommend xxx to be 166 -- The Textual Conventions defined below are organized -- alphabetically MplsBitRate ::= TEXTUAL-CONVENTION DISPLAY-HINT "d" STATUS current DESCRIPTION "An estimate of bandwidth in units of 1,000 bits per second. If this object reports a value of 'n' then the rate of the object is somewhere in the range of 'n-500' to 'n+499'. For objects which do not vary in bit rate, or for those where no accurate estimation can be made, this object should contain the nominal bit rate." SYNTAX Integer32 (1..2147483647) MplsBurstSize ::= TEXTUAL-CONVENTION DISPLAY-HINT "d" STATUS current DESCRIPTION "The number of octets of MPLS data that the stream may send back-to-back without concern for policing." SYNTAX Unsigned32 (1..4294967295) MplsExtendedTunnelId ::= TEXTUAL-CONVENTION STATUS current DESCRIPTION "A unique identifier for an MPLS Tunnel. This MAY represent an IpV4 address of the ingress or egress LSR for the tunnel. This value is derived from the Extended Tunnel Id in RSVP or the Ingress Router ID for CR-LDP." SYNTAX Unsigned32 REFERENCE "1. Awduche, D., et al., RSVP-TE: Extensions to RSVP for LSP Tunnels, draft-ietf-mpls-rsvp-lsp-tunnel-08.txt, February 2001. 2. Constraint-Based LSP Setup using LDP, Jamoussi, B., et al., draft-ietf-mpls-cr-ldp-05.txt, February 2001." MplsLabel ::= TEXTUAL-CONVENTION STATUS current DESCRIPTION "This value represents an MPLS label. The label contents are specific to the label being represented. The label carried in an MPLS shim header (for LDP, the Generic Label) is a 20-bit number represented by 4 octets. Bits 0-19 contain a label or a reserved label value. Bits 20-31 MUST be zero. The frame relay label can be represented by either 10-bits or 23-bits depending on the DLCI field size and the upper 22-bits or upper 9-bits must be zero, respectively. For an ATM label the lower 16-bits represents the VCI, the next 12-bits represents the VPI and the remaining bits MUST be zero." REFERENCE "1. MPLS Label Stack Encoding, Rosen et al, RFC 3032, January 2001. 2. Use of Label Switching on Frame Relay Networks, Conta et al, RFC 3034, January 2001. 3. MPLS using LDP and ATM VC switching, Davie et al, RFC 3035, January 2001." SYNTAX Unsigned32 (0..4294967295) -- A similar TC is also used in RFC2677.txt. NOTE: since -- MPLS's goal is to be any layer2 over any layer3, this -- MIB makes every attempt to define a TC which would -- satisfy L2 and L3 address sizes for now and in -- the future. MplsLdpGenAddr ::= TEXTUAL-CONVENTION STATUS current DESCRIPTION "The value of an network layer or data link layer address." SYNTAX OCTET STRING (SIZE (0..64)) MplsLdpIdentifier ::= TEXTUAL-CONVENTION STATUS current DESCRIPTION "The LDP identifier is a six octet quantity which is used to identify an Label Switch Router (LSR) label space. The first four octets encode an IP address assigned to the LSR, and the last two octets identify a specific label space within the LSR." SYNTAX OCTET STRING (SIZE (6)) MplsLdpLabelTypes ::= TEXTUAL-CONVENTION STATUS current DESCRIPTION "The Layer 2 label types which are defined for MPLS LDP/CRLDP are generic(1), atm(2), or frameRelay(3)." SYNTAX INTEGER { generic(1), atm(2), frameRelay(3) } -- This was taken from rfc2514.txt (AtmVcIdentifier) and -- modified here for MPLS. -- This TC agrees with "MPLS using LDP and ATM VC Switching" -- document which specifies that VC values need -- to be greater than 31, or in other words, 0-31 are -- reserved for other uses by the ITU and ATM Forum. MplsAtmVcIdentifier ::= TEXTUAL-CONVENTION STATUS current DESCRIPTION "The VCI value for a VCL. The maximum VCI value cannot exceed the value allowable by atmInterfaceMaxVciBits defined in ATM-MIB. The minimum value is 32, values 0 to 31 are reserved for other uses by the ITU and ATM Forum. 32 is typically the default value for the Control VC." SYNTAX Integer32 (32..65535) MplsLSPID ::= TEXTUAL-CONVENTION STATUS current DESCRIPTION "An identifier that is assigned to each LSP and is used to uniquely identify it. This is assigned at the head end of the LSP and can be used by all LSRs to identify this LSP. This value is piggybacked by the signaling protocol when this LSP is signaled within the network. This identifier can then be used at each LSR to identify which labels are being swapped to other labels for this LSP. For IPv4 addresses this results in a 6-octet long cookie." SYNTAX OCTET STRING (SIZE (0..31)) MplsLsrIdentifier ::= TEXTUAL-CONVENTION STATUS current DESCRIPTION "The Label Switch Router (LSR) identifier is the first 4 bytes or the Router Id component of the Label Distribution Protocol (LDP) identifier." SYNTAX OCTET STRING (SIZE (4)) MplsInitialCreationSource ::= TEXTUAL-CONVENTION STATUS current DESCRIPTION "The entity that originally created the object in question. The values of this enumeration are defined as follows: other(1) - This is used when an entity which has not been enumerated in this textual convention but which is known by the agent. snmp(2) - The Simple Network Management Protocol was used to configure this object initially. ldp(3) - The Label Distribution Protocol was used to configure this object initially. rsvp(4) - The Resource Reservation Protocol was used to configure this object initially. crldp(5) - The Constraint-Based Label Distribution Protocol was used to configure this object initially. policyAgent(6) - A policy agent (perhaps in combination with one of the above protocols) was used to configure this object initially. unknown(7) -- the agent cannot discern which component created the object." SYNTAX INTEGER { other(1), snmp(2), ldp(3), rsvp(4), crldp(5), policyAgent(6), unknown (7) } MplsPathIndex ::= TEXTUAL-CONVENTION STATUS current DESCRIPTION "A unique identifier used to identify a specific path used by a tunnel." SYNTAX Unsigned32 MplsPathIndexOrZero ::= TEXTUAL-CONVENTION STATUS current DESCRIPTION "A unique identifier used to identify a specific path used by a tunnel. If this value is set to 0, it indicates that no path is in use." SYNTAX Unsigned32 MplsTunnelAffinity ::= TEXTUAL-CONVENTION STATUS current DESCRIPTION "Include-any, include-all, or exclude-all constraint for link selection." SYNTAX Unsigned32 MplsTunnelIndex ::= TEXTUAL-CONVENTION STATUS current DESCRIPTION "Index into mplsTunnelTable." SYNTAX Integer32 (1..65535) MplsTunnelInstanceIndex ::= TEXTUAL-CONVENTION STATUS current DESCRIPTION "Instance index into mplsTunnelTable."
