CISCO-VISM-CONN-MIB Download
The MIB module to contains configuration
and connection state information the VISM.
For VoIP(Voice over IP) support, VISM needs one
active AAL5 bearer PVC and one active AAL5
control PVC between the VISM card and the PXM.
The redundant PVC feature is supported for AAL5
PVCs. Each redundant PVC pair has one active
PVC and one standby PVC. There can be one AAL5
bearer redundant PVC pair and one AAL5
control redundant PVC pair.
All PVCs are added on the ATM virtual port=1.
For the AAL2 trunking application, there can
be multiple AAL2 bearer PVCs. Also, AAL2 bearer
PVC in this case, is between the two media
gateways, instead of just between the VISM and
the PXM. Up to 64 AAL2 bearer PVCs are supported
for this application.
IPHost Network Monitor offer an easy way of SNMP monitoring your Cisco Servers, Routers, Switches, Bridges,
Firewalls, Repeaters.
OID list for CISCO-VISM-CONN-MIB
- vismChanCnfGrpTable
- The channel configuration table for voice traffic.
- vismChanCnfGrpEntry
- An entry for each voice channel. An entry is created when the vismChanRowStatus is set to 'add'. An entry is deleted when the vismChanRowStatus is set to 'del'. INDEX { vismCnfChanNum } ::= { vismChanCnfGrpTable 1 } VismChanCnfGrpEntry ::= SEQUENCE { vism ...
- vismChanRowStatus
- An entry is created by setting this object to 'add (1)' : Adds an entry to the table. 'mod (3)' : This is used to modify an existing entry. 'del (2)' : This is used to delete an existing. 'outOfService (4)': Setting this object to this value takes the cha ...
- vismConnServiceType
- This specifies the class of service or service type 'cbr (1)' : Constant Bit Rate. 'vbr-rt (2)' : Variable Bit Rate 1 (Real Time) although, VISM does not do any kind of traffic shaping, the PVC has to be specified as vbr-rt for PXM to treat the connection ...
- vismChanDirectRoute
- This object serves to associate a preferred route as directed route (corresponds to the preferred route object vismChanPrefRouteId). A directed route specifies that the associated preferred route is the only permission route for the connection to take. Sh ...
- vismChanAisSuppression
- AIS suppression can be enabled(true) or disabled(false). When AIS suppression is disabled on a PVC, ATM network alarms on that PVC will immediately propagate to the TDM side and cause T1/E1 line alarms. When AIS suppression is enabled on a PVC, ATM netwo ...
- vismChanAisDelayTime
- This object defines the duration for which ATM network alarms on this PVC will be prevented from propagating onto the TDM side when AIS suppression is enabled.
- vismChanUserMaxPCRBandwidth
- This indicates a user configured bandwidth (Peak Cell Rate) in cells per second from the local end i.e in the ingress direction of the PVC. For a VoIP bearer PVC, the max value is 75600 cps. For a VoIP control PVC, the max value is 24400 cps. For AAL2 PVC ...
- vismChanUserMaxMbsIngress
- This object defines the user configured MBS (Maximum Burst Size). This object is meaningful for VBR connections only. This object defines the MBS value for the ingress direction of the PVC. The MBS value cannot be greater than 10 times vismChanScrIngress ...
- vismChanUserMinPCRBandwidth
- This indicates a user configured minimum number of cells that will be required to keep the connection up.
- vismChanUserPcrNumber
- This indicates which bandwidth value the user has chosen. This value cannot be specified when adding the connection. It can be modified once the connection has been added. If it has a value of userConfiguredMaxBandwidth, it indicates that the bandwidth co ...
- vismChanNumNextAvailable
- This object contains the next unused channel number. When channels are available the range is 32..510. This number can be used in channel config table. Value 0 for this object indicates that no more channels are available.
- vismChanStateGrpTable
- voice connection state table.
- vismChanStateGrpEntry
- An entry for each channel (PVC).
- vismStateChanNum
- Refers to the channel Number LCN. ::= { vismChanStateGrpEntry 1 } SYNTAX INTEGER { notConfigured (1), okay (2), alarm (3) } MAX-ACCESS read-only STATUS current DESCRIPTION This object indicates the channel status. 'notConfigure ...
- ciscoVismConnGroup
- A collection of objects providing information applicable to connections in VISM Module. ::= { ciscoVismConnMIBGroups 1 } OBJECTS { vismStateChanNum, vismChanState, vismChanXmtATMState, vismChanRcvATMState, vismChanStatusBitMap } STATUS current DESCRIPTION ...
