CISCO-IMA-MIB
AI MIB Summary
The CISCO-IMA-MIB enables SNMP-based monitoring and management of Cisco Inverse Multiplexing for ATM (IMA) groups, specifically tracking link synchronization states, ICP control protocol status, and defect counters such as LIF, LODS, and HEC errors. It provides visibility into the operational integrity of ATM link aggregation by exposing metrics for cell identification, data compensation buffers, and group state machine transitions defined in the ATM Forum IMA specification.
The MIB module describes Cisco IMA objects. This is an extension to the standard of ATM Forum IMA version 1.1, AF-PHY-0086.001 Spec. atmfImaMib.

cimaGroupTableThe Cisco IMA group table. This table contains Cisco extension
objects for the imaGroupTable. Each entry in the table contains
Cisco specific configuration, control, and status information
for each IMA group. SEQUENCE OF CimaGroupEntry .1.3.6.1.4.1.9.9.235.1.3 |
cimaGroupEntryAn entry in the table containing additional management
information applicable to a Cisco card/platform. When
an entry is successfully created here, an entry in interfaces
table is created with
ifType value of atmIma(107),
ifAdminStatus value of down(2),
ifOperStatus value of down(2). CimaGroupEntry .1.3.6.1.4.1.9.9.235.1.3.1 |
cimaGroupAccumulatedDelayThis object indicates the amount of data per link that is
accumulated in the Delay Compensation Buffers of the
IMA group. This is a result of deleting the slowest
link of the IMA group.ro MilliSeconds -- Rsyntax INTEGER -- Units -- millisecond .1.3.6.1.4.1.9.9.235.1.3.1.1 |
cimaGroupClearAccDelayThis object indicates whether or not to clear accumulated
delays of the IMA group. When the delay is cleared, the
group Delay Compensation Buffers are cleared such that the
current slowest link in the group does not have any data
accumulated in its DCB. As a result of this action, the data
is played out to the network faster than the portrate.
The agent clears the IMA group accumulated delays when
this object is set to value of true(1) from a manager.
This is a control object which can be changed/modified when
the imaGroupRowStatus is 'active'.rw TruthValue -- Rsyntax INTEGER { -- true(1), -- false(2) -- } .1.3.6.1.4.1.9.9.235.1.3.1.2 |

cimaGrpNumRxInvalidIcpCellsNumber of Invalid ICP Cells received on
this IMA group.
Invalid ICP Cell is defined as:

= ICP at expected frame position with
(unexpected IMA OAM Label) or
(unexpected LID) or
(unexpected IMA ID) or
(received M not equal to
expected M of the IMA group) or

transmitted on this IMA group due to
lack of resources, e.g. buffers.ro Counter -- Units -- cells .1.3.6.1.4.1.9.9.235.1.3.1.11 |
cimaGrpRestartingThe object controls if the IMA group restart is to
be executed. During this operation the Group bringup
procedure is restarted and the group will have to go
through all the state transitions before it is declared
Active.
true(1) - restarting the IMA group
false(2) - do not restart the IMA group
The agent restarts the IMA group if it is set
to value of true(1) request from a manager. When the
agent is in the group restart transition state,
it does not take any set to value of true(1) requests.
The agent returns true(1) when it is in the process
of group bringup. The agent returns false(2) after
the completion of group restarting.rw TruthValue -- Rsyntax INTEGER { -- true(1), -- false(2) -- } .1.3.6.1.4.1.9.9.235.1.3.1.12 |

cimaGrpMaxCellRateThis object indicates the IMA group's high water mark
cell rate. The value is the same as the IMA Data Cell
Rate(IDCR) with all configured links in the 'active'
state.
It is derived according to the following equation:
T1 based group = N * (3622 * (M-1)/M * 2048/2049)
E1 based group = N * (4528 * (M-1)/M * 2048/2049)
where
N = number of links in the IMA group
M = IMA group frame length.ro Gauge -- Units -- cells per second .1.3.6.1.4.1.9.9.235.1.3.1.14 |
cimaLinkMappingTableThe link mapping table is an IMA group oriented mapping table
which associates an IMA group to its corresponding IMA links.
It provides an efficient way of accessing to IMA links
based on the knowledge of an IMA group.
This is a read-only mapping table. The agent creates an entry
when an IMA link identified by 'imaLinkIfIndex' is added to
an IMA group identified by 'imaGroupIndex'. The agent removes
an entry when an IMA link identified by 'imaLinkIfIndex' is
removed from an IMA group identified by 'imaGroupIndex'.
A state object 'cimaLinkState' provides the link state in
either 'active' or 'nonactive'. The management staion can query
detailed information in imaGroupTable, and imaLinkTable with
the two index readily available. SEQUENCE OF CimaLinkMappingEntry .1.3.6.1.4.1.9.9.235.1.4 |
