Description: Manages IEEE 802.2 Logical Link Control (LLC) parameters and statistics for SNA traffic on Cisco routers.
Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.
What Is CISCO-SNA-LLC-MIB?
This is a Cisco enterprise MIB for managing IEEE 802.2 Logical Link Control (LLC) parameters and statistics used to carry SNA (Systems Network Architecture) traffic over Cisco router LLC2 ports. It exposes per-port LLC administrative configuration: maximum SAPs, maximum outstanding command/response counts, max PDU size, unacknowledged I-PDU windows for send/receive, retransmission limits, and acknowledgment/P-bit timers. It supports monitoring the operational configuration and performance tuning of LLC data-link connections carrying legacy SNA traffic, useful for diagnosing retransmission or throughput problems on SNA-over-LAN links, a protocol/software-level health indicator rather than a physical hardware one. It builds on the IEEE 802.2 LLC standard and is used alongside Cisco's broader SNA/DLSw feature set for legacy mainframe connectivity. It is deployed on Cisco routers providing SNA/APPN connectivity between mainframes and LAN-attached devices, where network engineers tune and monitor per-port LLC parameters to keep legacy SNA sessions stable. Engineers can download the CISCO-SNA-LLC-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-SNA-LLC-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
- Cisco router (SNA/DLSw gateway)
Monitoring Examples
An engineer inspects llcPortAdminTable/llcPortAdminEntry rows, indexed by llcPortVirtualIndex and named via llcPortAdminName, to review llcPortAdminMaxSaps and the llcPortAdminMaxUnackedIPDUsSend/Rcv window sizes configured for an SNA-carrying LLC port. If llcPortAdminMaxRetransmits is being hit frequently alongside a low llcPortAdminAckTimer, that suggests the LLC2 connection is retransmitting excessively, a sign of an unstable or congested link. The llcPortAdminPbitTimer and llcPortAdminMaxPDUOctets settings, grouped under llcPortGroup and llcSapGroup, are checked to confirm SAP-level parameters match what the mainframe-side SNA gateway expects.
What Can Be Monitored
- LLC port configuration
- maximum SAPs per port
- unacknowledged I-PDU window sizes
- retransmission counts
- acknowledgment/P-bit timers

How to Use in IPNetwork Monitor
Example using llcPortStatsPDUsIn OID:
Select a Cisco router (SNA/DLSw gateway, legacy) as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type llcPortStatsPDUsIn into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. This object reflects the total number of PDUs that have been received on this port. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is a Counter32-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases sharply between polls relative to its normal baseline, since an unexpected spike often reflects a real change in traffic or activity. Click Finish to create the monitor; you can adjust any parameter later.

This must be less than or equal to the value of llcCcOperMaxUnackIPDURcv. This function is not described in the IEEE 802.2 specification [5] but is widely implemented. This object contains an administrative value which will be applied the next time this connection is established. A zero value for this object indicates that the SAP default, llcSapAdminDelayAck, shall be used. A value of one indicates that acknowledgments will be sent immediately and that the value of llcCcAdminDelayAckTimer shall be ignored. |

| llcCcAdminTable | 1.3.6.1.4.1.9.10.8.1.3.1 | not-accessible | This table contains objects that can be changed to manage an LLC connection component. Changing one of these parameters may take effect in the operating link immediately or may wait until the link is restarted depending on the details of the implementation. The entries in llcCcAdminTable can be created either by an agent or a management station. The management station can create an entry in llcCcAdminTable by setting the appropriate value in llcCcAdminRowStatus. Most of the objects in this read-create table have corresponding read-only objects in the llcCcOperTable that reflect the current operating value. The operating values may be different from these configured values if changed by XID negotiation or if a configured parameter was changed after the link was started. | |
