SNMP Interfaces
The SNMP Interface Monitor Entity editor supports the following entity types: group, equipment
manager, port and interface. It also supports port and interface filters on groups and equipment
manager objects.
If you check the Collect from ifXTable checkbox, then OpenManage Network Manager attempts to
fetch attributes from the ifXTable. These attributes are ifHighSpeed, ifHCInOctets,
ifHCInUcastPkts, ifHCOutOctets and ifHCOutUcastPkts. If any of these attributes are not
available, then it fetches from ifTable.
If an interface does not support ifxTable, SNMP get typically retrieves an error and Dell
If an interface does not support ifxTable, SNMP get typically retrieves an error and Dell
OpenManage Network Manager uses the ifTable instead. Some ATM ports do not send errors from
the ifxTable oids, so Dell OpenManage Network Manager also uses the ifTable values if
ifHighSpeed is 0.
NOTE:
The SNMP V1 protocol does not support 64bit counters located in ifXtable. This means Dell OpenManage
Network Manager monitors only collect performance data from ifTable when a device is discovered
using the SNMP V1 protocol. Best practice: Discover devices using snmpV2c or snmpV3 protocols to
collect performance data located in ifXtable.
