IP Performance Manager reads the following MIBs to determine the duplex mode value for a network adapter:
-
Checks for a duplex mode value in the enterprise-specific MIB.
If found and the value is full-duplex or half-duplex, sets DuplexMode to FULLDUPLEX or HALFDUPLEX and sets DuplexSource to ENTERPRISE_MIB. If no value is found or the found value is not understood, IP Performance Manager continues to the next step.
-
Checks for a duplex mode value in the ETHERLIKE- MIB.
If found and the value is full-duplex or half-duplex, sets DuplexMode to FULLDUPLEX or HALFDUPLEX and sets DuplexSource to ETHERLIKE_MIB. If no value is found or the found value is not understood, IP Performance Manager continues to the next step.
-
Checks for a duplex mode value in the neighbor MIB.
If found and the value is full-duplex or half-duplex, sets DuplexMode to FULLDUPLEX or HALFDUPLEX for both local and remote ports and sets DuplexSource to NEIGHBOR_MIB. If no value is found or the found value is not understood, IP Performance Manager continues to the next step.
-
Checks the value of ICF_TopologyManager::ICF-TopologyManager::DuplexAssumed.
The value of this attribute is the value of the DuplexAssumed parameter in the discovery.conf file. At this point in the search for a duplex mode setting, IP Performance Manager uses the DuplexAssumed value to determine the values for the network adapter’s DuplexMode and DuplexSource attributes.
