IF-MIB Chapter 8 Industry-Standard Management Information Base This data type is used to model an administratively assigned name of the owner of a resource. This information is taken from the NVT ASCII character set. It is suggested that this name contain one or more of the following: ASCII form of the manager station's transport address, management station name (e.g., domain name), network management personnel's name, location, or phone number. In some cases the agent itself will be the owner of an entry. In these cases, this string shall be set to a string starting with agent. A value which indicates the set of services that this entity may potentially offers. The value is a sum. This sum initially takes the value zero, Then, for each layer, L, in the range 1 through 7, that this node performs transactions for, 2 raised to (L - 1) is added to the sum. For example, a node which performs only routing functions would have a value of 4 (2^(3-1)). In contrast, a node which is a host offering application services would have a value of 72 (2^(4-1) + 2^(7-1)). Note that in the context of the Internet suite of protocols, values should be calculated accordingly: Layer functionality: - 1-physical (e.g., repeaters) - 2-datalink/subnetwork (e.g., bridges) - 3-internet (e.g., supports the IP) - 4-end-to-end (e.g., supports the TCP) - 7-applications (e.g., supports the SMTP) For systems including OSI protocols, layers 5 and 6 may also be counted. SYNTAX Octet String (SIZE(0..255)) Interface Index The Interface Index contains the semantics of ifIndex and should be used for any objects defined in other MIB modules that need these semantics. InterfaceIndex ::= TEXTUAL-CONVENTION DISPLAY-HINT d STATUS current DESCRIPTION A unique value, greater than zero, for each interface or interface sub-layer in the managed system. It is recommended that values are assigned contiguously starting from 1. The value for each interface sub-layer must remain constant at least from one re-initialization of the entity's network management system to the next re-initialization. SYNTAX Integer32 (1..2147483647) InterfaceIndexOrZero ::= TEXTUAL-CONVENTION DISPLAY-HINT d STATUS current DESCRIPTION This textual convention is an extension of the InterfaceIndex convention. The latter defines a greater than zero value used to identify an interface or interface sub-layer in the managed system. This extension permits the additional value of zero. The value zero is object-specific and must therefore 8-108 Cisco Unified Communications Manager Managed Services Guide OL-22523-01
