CISCO-CDMA-AHDLC-MIB
AI MIB Summary
The CISCO-CDMA-AHDLC-MIB monitors the operational state, performance counters, and configuration parameters of Cisco hardware and software AHDLC engines and their associated channels within 3G CDMA Packet Data Serving Node (PDSN) environments. It specifically tracks metrics for Asynchronous High-level Data Link Control sessions, including engine status, channel utilization, and framing performance, to facilitate troubleshooting of the data link layer between the Radio Access Network (RAN) and the PDSN.
This MIB module provides details concerning AHDLC engine state, performance, configuration and notification.
An AHDLC channel handles one AHDLC session. AN AHDLC engine controls a set of AHDLC channels.
The following diagram illustrates a typical usage of an AHDLC service adapter in a 3G CDMA wireless data network

Two types of AHDLC engines are available - software and hardware based. A dedicated hardware allows better ahdlc framing performance.

cCdmaAhdlcEngineTableA list of AHDLC engines available in the system. SEQUENCE OF CCdmaAhdlcEngineEntry .1.3.6.1.4.1.9.9.306.1.1.1 |
cCdmaAhdlcEngineEntryA description of an AHDLC engine. CCdmaAhdlcEngineEntry .1.3.6.1.4.1.9.9.306.1.1.1.1 |
cCdmaAhdlcEngineIndexAn arbitrary non-zero integer-value that uniquely
identifies an AHDLC engine. An implementation should
assign AHDLC engines consecutive monotonically
increasing values. Gauge .1.3.6.1.4.1.9.9.306.1.1.1.1.1 |
cCdmaAhdlcEngineNameTextual name of the AHDLC engine. The value of this
object should be the name of the component as
assigned by the local device.ro SnmpAdminString -- Rsyntax OCTET STRING .1.3.6.1.4.1.9.9.306.1.1.1.1.2 |
cCdmaAhdlcEngineTypeAHDLC engine type. Three main types are defined:
- a 'hardware' based engine requires the use of
AHDLC hardware assist. Each hardware based engine is
peer to one unique AHDLC hardware assist.
- a 'software' based engine is not peer to an AHDLC
hardware assist but it relies on the system cpu(s) to
perform AHDLC framing.
If the engine type cannot be determined, this object
value should return 'unknown'.ro Enumeration .1.3.6.1.4.1.9.9.306.1.1.1.1.3 |
cCdmaAhdlcEngineChannelsInUseNumber of current active channels handled by this
engine.ro Gauge .1.3.6.1.4.1.9.9.306.1.1.1.1.4 |
cCdmaAhdlcEngineMaxChannelsMaximum number of channels that can be supported
by this engine.ro Gauge .1.3.6.1.4.1.9.9.306.1.1.1.1.5 |

This value may not be higher than
cCdmaAhdlcEngineMaxChannels.rw Gauge .1.3.6.1.4.1.9.9.306.1.1.1.1.6 |
cCdmaAhdlcEngineOperStateThis object defines the current AHDLC engine
operational state. The 'up' indicates the engine
is ready to receive ahdlc packets.
If cCdmaAhdlcEngineAdminState is 'down' then
cCdmaAhdlcEngineOperState should be 'down'. If
cCdmaAhdlcEngineAdminState is changed to 'up' then
cCdmaAhdlcEngineOperState should change to 'up'
if the engine is ready to receive ahdlc packets;
it should remain in the 'down' state if and only
if there is a fault that prevents it from going to
the 'up' state.ro Enumeration .1.3.6.1.4.1.9.9.306.1.1.1.1.7 |
cCdmaAhdlcEngineAdminStateThis object defines the AHDLC engine desired
state. When a managed system initializes, all
interfaces start with 'down' state. As a result
of either explicit management action or per
configuration information retained by the managed
system, cCdmaAhdlcEngineAdminState is then changed
to either 'up' or remains in the 'down' state.rw Enumeration .1.3.6.1.4.1.9.9.306.1.1.1.1.8 |
cCdmaAhdlcEngineDownNotifEnabled'true' indicates notification will be sent out
when cCdmaAhdlcEngineAdminState is 'up' and
cCdmaAhdlcEngineOperState is 'down'.rw TruthValue -- Rsyntax INTEGER { -- true(1), -- false(2) -- } .1.3.6.1.4.1.9.9.306.1.1.1.1.9 |
