Description: Defines textual conventions for TN3270E terminal emulation management, used by the TN3270E-MIB and TN3270E-RT-MIB modules.
IPNetwork Monitor uses several OIDs from this MIB in network discovery and polling the applicable devices. Start monitoring IANATn3270eTC-MIB with a free 30-day trial of IPNetwork Monitor.
What Is IANATn3270eTC-MIB?
IANATn3270eTC-MIB is an IANA-maintained standards-track MIB (registered under mib-2 61) that defines a shared set of textual conventions used by the TN3270E-MIB and TN3270E-RT-MIB for managing TN3270E terminal-emulation servers and sessions. It defines conventions such as IANATn3270eAddrType/IANATn3270eAddress for typed client addresses, IANATn3270eClientType for the format of a client identifier (IPv4/IPv6/DNS name/certificate/userid), IANATn3270Functions as a BITS enumeration of negotiated TN3270/TN3270E capabilities (transmitBinary, endOfRecord, scsCtlCodes, bindImage, sysreq, and others per their originating RFCs), IANATn3270DeviceType for supported IBM 3270 terminal/printer device models, and IANATn3270eLogData for a structured, time-ordered session event log format. Because it contains no OBJECT-TYPE definitions of its own, it is not directly polled; its value is in providing consistent typing for the client-facing MIBs that depend on it, which in turn expose real session and connection state for TN3270E gateways. It is referenced by TN3270E-MIB and TN3270E-RT-MIB, both IETF standards-track modules for TN3270E server management. It underlies TN3270E gateway/server implementations bridging IP clients to SNA 3270 terminal sessions, and the IANATn3270eTC-MIB RFC lineage traces back to RFC 2561's TN3270E working group textual conventions.
IPNetwork Monitor allows you to monitor SNMP objects defined in IANATn3270eTC-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.
Supported Devices
- vendor-neutral, standards-based MIB (IETF, registered under mib-2 61), not tied to a specific manufacturer
Monitoring Examples
An operator troubleshooting a TN3270E gateway inspects a client's negotiated capabilities as reported by an object typed IANATn3270Functions in the dependent TN3270E-MIB; a session missing the bindImage or responses bits that the SNA application requires would explain why that client cannot establish a full 3270 session, even though this TC module itself defines only the type, not the live session table.
What Can Be Monitored
- client address type/format used by dependent TN3270E MIBs
- client identifier format (IPv4/IPv6/DNS/certificate/userid)
- negotiated TN3270/TN3270E function capability bits
- supported 3270 terminal/printer device type
- structured session event log entries
