MIB Support for Advanced Network Management Awareness
SNASw supports the following Management Information Bases (MIBs):
•IETF draft standard DLUR MIB (RFC 2232), which defines objects for monitoring and controlling network devices with DLUR (Dependent LU Requester) capabilities.
•IETF draft standard APPN MIB (RFC 2455), which defines objects for monitoring and controlling network devices with Advanced
•APPN Traps MIB (RFC 2456), which defines objects for receiving notifications from network devices with APPN and DLUR capabilities. This MIB proactively send traps with information about changes in SNA resource status. This implementation reduces the frequency of SNMP polling necessary to manage SNA devices in the network.
The CiscoWorks Blue Maps application retrieves relevant SNASw data from these MIBs and displays it in a manner that simplifies and speeds up problem isolation and resolution.
LAN and IP-Focused Connection Types
SNASw supports several connection types to serve all SNA connectivity options, including the following types:
•Token Ring, Ethernet, and FDDI, page 238
•Virtual Token Ring, page 238
•Virtual
•Native IP
Token Ring, Ethernet, and FDDI
SNASw natively supports connectivity to Token Ring, Ethernet, and FDDI networks. In this configuration mode, the MAC address used by SNASw is the local configured or default MAC address of the interface.
Virtual Token Ring
Using virtual Token Ring allows SNASw access to SRB, which allows the following configuration:
•Attachment to Local LANs, page 238
•Connection to Frame Relay Transport Technologies, page 239
•Connection to Channel Interface Processor and Channel Port Adapter, page 239
Attachment to Local LANs
Virtual Token Ring allows you to connect to local LAN media through SRB technology. Because there is no limit to the number of virtual Token Ring interfaces that can connect to a specific LAN, this technology allows configuration of multiple MAC addresses, which respond to SNA requests over the
