CISCO-OPTICAL-IF-CROSS-CONNECT-MIB Download
This MIB module is used to create and monitor cross-connects
(horizontal relationships) between peer interfaces on the same
network element. Vertical relationships (e.g. between lambdas
and the optical fiber in which the lambdas are carried) are
represented in the ifStackTable from the IF-MIB.
This MIB can be used to model various types of cross-connects
between peer interfaces, including time-division (e.g.
SDH/SONET, PDH), wavelength (lambda), and spatial switching
(e.g. incoming port or fiber to outgoing port or fiber).
This MIB does not apply to cross-connects between packet flows
(e.g. packets in the same forwarding equivalence class at a
MPLS-capable switch or router) or cell flows (e.g. ATM Virtual
Path connections or ATM Virtual Channel connections), since
there are scalability issues in modeling each packet flow or
cell flow as a logical interface.
The switching element performing the cross-connect function can
be electrical (e.g. SDH/SONET switch) or optical (e.g. passive
optical add/drop multiplexer)
Cross-connects can be created through provisioning,
automatically by the network element, or dynamically by using
control protocols (e.g. GMPLS).
The cross-connect model includes support for pairs of
interfaces used to protect each other (e.g. SONET 1+1
Automatic Protection Switching). Cross-connects to protection
interfaces may be shown in this MIB module.

OID list for CISCO-OPTICAL-IF-CROSS-CONNECT-MIB
- coifccInterfaceTable
- This table lists all interfaces that are cross-connected to one or more other interfaces. The table is used to find cross-connects that include a particular interface.
- coifccInterfaceEntry
- An entry is created only when an interface is cross-connected to one or more other interfaces (i.e. when the associated entries in the coifccCrossConnectTable have been created). An entry is deleted when an interface is removed from a cross-connect, or wh ...
- coifccIfCrossConnectIdentifier
- The value of coifccCcIndex used in the coifccCrossConnectTable to identify a cross-connect that includes this interface. Each interface included in that cross-connect has an entry in this table with the same value of this object, in addition to the entri ...
- coifccCcIndexNext
- This object contains an appropriate value to be used for coifccCcIndex when creating entries in the coifccCrossConnectTable. The value 0 indicates that no unassigned entries are available. To obtain the coifccCcIndex value for a new entry, the manager iss ...
- coifccCcLastChange
- The value of sysUpTime at the time of the last creation, deletion or modification of an entry in the coifccCrossConnectTable. If the coifccCrossConnectTable entries has been unchanged since the last re-initialization of the local network management subsys ...
- coifccCrossConnectTable
- This table contains configuration and state information of point-to-point and point-to-multipoint interface cross-connects. Each entry in the table models two bi-directional interfaces on opposite sides of a bi-directional cross-connect. For a point-to-po ...
- coifccCrossConnectEntry
- This entry is used to model two bi-directional cross-connected interfaces. Cross-connects can be created through provisioning, automatically by the network element, dynamically by using control protocols (e.g. GMPLS), or due to the presence of protection ...
- coifccCcIndex
- A unique value used to identify this cross-connect. For each interface associated with this cross-connect, the agent reports this cross-connect index value in the coifccIfCrossConnectIdentifier object of the corresponding coifccInterfaceTable entry. When ...
- coifccCcLowIfIndex
- The value of this object is equal to MIB II's ifIndex value of the interface for this cross-connect. The term low implies that this interface has the numerically lower ifIndex value than the other interface identified in the same coifccCrossConnectEntry.
- coifccCcHighIfIndex
- The value of this object is equal to MIB II's ifIndex value of the interface for this cross-connect. The term high implies that this interface has the numerically higher ifIndex value than the other interface identified in the same coifccCrossConnectEntr ...
- coifccCcSwitchType
- This object specifies the type of switching element used to implement this cross-connect. The value 'opticalCrossConnect' applies only when there is no optical-to-electrical conversion performed to implement the cross-connect. The value 'autoSelect' indic ...
- coifccCcKind
- The type of call control used to establish a cross-connect. If no value of this object is provided when a row is activated through SNMP, then the value 'provisioned' is assigned by the agent. For point-to-point cross-connects, the only sets allowed on thi ...
- coifccCcCreationTime
- The value of MIB II's sysUpTime object at the time this bi-directional cross-connect was created. If the current state was entered prior to the last re-initialization of the agent then this object contains a zero value.
- coifccCcL2HOperStatus
- The operational status of the cross-connect in the direction from the interface that has the numerically lower ifIndex value, to the interface that has the numerically higher ifIndex value.
- coifccCcH2LOperStatus
- The operational status of the cross-connect in the direction from the interface that has the numerically higher ifIndex value, to the interface that has the numerically lower ifIndex value.
- coifccCcL2HLastChange
- The value of MIB II's sysUpTime at the time this cross-connect entered its current operational state in the low to high direction. If the current state was entered prior to the last re-initialization of the agent then this object contains a zero value.
- coifccCcH2LLastChange
- The value of MIB II's sysUpTime at the time this cross-connect entered its current operational state in the high to low direction. If the current state was entered prior to the last re-initialization of the agent then this object contains a zero value.
- coifccCcRowStatus
- The status of this entry in the coifccCrossConnectTable. This object is used to create a cross-connect or to modify or delete an existing cross-connect. Write access does not apply to entries with coifccCcKind values of 'automatic' or 'protection'. Entri ...
- coifccCcL2HAttenuation
- The value of this object indicates optical signal attenuation due to connectors, optical wavelength filters, optical switches, and other optical components, in the direction from the interface that has the numerically lower ifIndex value, to the interface ...
- coifccCcH2LAttenuation
- The value of this object indicates optical signal attenuation due to connectors, optical wavelength filters, optical switches, and other optical components, in the direction from the interface that has the numerically higher ifIndex value, to the interfac ...
