Description: Manages ALPS (Airline Protocol Support) for SNA-based airline reservation system connectivity 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-ALPS-MIB?
CISCO-ALPS-MIB supports ALPS (Airline Protocol Support), a legacy Cisco feature that carries SNA-based airline reservation-system traffic, including Airline X.25 (AX.25), over IP between router pairs acting as ALPS gateways. Its data covers configuration (peer IP/port, keepalive timers, retry counts, call-accept flags) and status (remote peer connection state). It is primarily a connectivity/software-session-status MIB: tracking whether the ALPS peer sessions carrying critical reservation-system traffic are established, since a down peer session represents an outage of that legacy application path. It is explicitly built on legacy protocols referenced in its description (AX.25, EMTOX, ASCU), a niche, protocol-specific dependency. It is deployed on legacy Cisco routers at airline/travel-industry sites still relying on SNA-based reservation systems tunneled over IP, typically beginning with a CISCO-ALPS-MIB download to load its object definitions into a MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-ALPS-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 configured for ALPS/SNA airline reservation traffic
Monitoring Examples
alpsRemPeerTable, keyed by peer IP and port, exposes alpsRemPeerState, letting an operator confirm whether a given ALPS peer connection to a remote router is up; a state stuck at connecting rather than connected indicates the SNA reservation-traffic path between sites is down. alpsPeerKeepaliveTimeout and alpsPeerKeepaliveMaxRetries can be checked to confirm the configured tolerance before a peer is declared down, helping distinguish a transient blip from a genuine peer failure.
What Can Be Monitored
- ALPS remote peer connection state
- peer keepalive timeout/retry settings
- peer IP address and port
- call-accept configuration

How to Use in IPNetwork Monitor
Example using alpsRemPeerConnOutPackets OID:
Select a Cisco router (ALPS/SNA airline traffic, 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 alpsRemPeerConnOutPackets 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. It reports the number of packets transmitted on this ALPS remote peer connection. 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 (in packets), 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.

Based on the terminal's capabilities, one of these three is configured for the ASCU. Note that this option is the same for all terminals connected to an ASCU because the ALPS feature does not handle individual terminals |

Also, ASCUs configured after the circuit has been established are not added dynamically to the circuit but are marked NEW and get added when the circuit gets established the next time. ASCUs waiting for an accept or reject response from the host are marked as PENDING. ASCUs that were accepted by the host are marked OK. |
| alpsCktAscuTable | 1.3.6.1.4.1.9.9.95.1.3.4 | not-accessible | A list of ASCUs for each ALPS Circuit. This may not include all ASCUs which have this circuit configured as alpsAscuCktName because some ASCUs may be rejected by the host while setting up the circuit. | |

The host link number is used to provide a degree of transparency to the remote router. A single host link may correspond to multiple physical links between the central router and the host, which can then load-balance VCs across them. |

The ALPS MIB provides configuration and operational information for Cisco's Airline protocol support for IBM-P1024B(ALC) and Unisys-P1024C(UTS) protocols encapsulation over TCP/IP. The following entities are managed: 1. Peers 2. ALPS Circuits 3. ASCUs (Agent Set Control Units) 4. ALC interface 5. ALPS Host link interface to the host HOST(Emtox/Ax.25) Central IP Network Remote ASCU router router The router connected to the Host is called the Central router and the router connected to the ASCU is called the Remote router. We anticipate one Central router connecting to a large number of Remote routers. Each router has a local peer, which connects to its counterpart on the other router (referred to as the remote peer) via a TCP connection. ALPS circuits are set up over this TCP connection either on a permanent or on-demand basis. A logical grouping of ASCUs are connected via a single circuit - this has no connection to the physical interfaces that the ASCUs are connected to. The only restriction is that all the ASCUs should be directly connected to the same router. Multiple ASCUs can connect to a single serial interface and several terminals connect to an ASCU. However, terminals are not visible to the ALPS feature - the router talks only to the ASCUs. An ASCU can be identified by * the interface it is on and its Interface Address (IA) or * the circuit it is on, and its A1 and A2 values, which identify it within the circuit. Thus there are two ways of identifying an ASCU - or Circuit names are globally unique. The connection to the host is via one of two flavors of X.25 - either AX.25 (for PVCs) or EMTOX (for SVCs). Each X.25 VC corresponds to one ALPS circuit. There are several hostlinks between a host and the Central router and load balancing is done across these. EMTOX allows the host to dial out to a terminal. This requires the use of an X.121 to IP address translation table to connect to the appropriate remote peer. | ||
