CISCO-ITP-SP2-MIB

The MIB for providing information specified in ITU Q752 Monitoring and Measurements for Signaling System No. 7(SS7) Network. This information can be used to manage messages transported over SS7 Network via Cisco IP Transfer Point. The Cisco IP Transfer Point (ITP) is a hardware and software solution that transports SS7 traffic using IP. Each ITP node provides function similar to SS7 signaling point. The relevant ITU documents describing this technology is the ITU Q series, including ITU Q.700: Introduction to CCITT Signaling System No. 7 and ITU Q.701 Functional description of the message transfer part (MTP) of Signaling System No. 7. The ITP Quality of Service (QoS) model allows the definition of 8 QoS classes, 0 through 7. QoS classes can be assigned only SCTP links. Only one QoS class can be assigned to an SCTP link. Class 0 will be designated as the default class. Packets that are not classified to a designated QoS class will get assigned to the default class. Each provisioned QoS class can be assigned an IP precedence value or a Differential Services Code Point (DSCP). The default class is initialized to IP precedence zero (0). The default class initial TOS setting can be changed through the command line interface. The Type of Service (TOS) byte in the IP header will be set to the IP precedence or DSCP that is assigned to class. Every packet forwarded over an SCTP link that was provisioned for a given QoS class will have the TOS byte set.
