Issue/Introduction

Symptoms:




Duplex status unknown for Alcatel switches
Duplex status is unknown for Alcatel switches in Smarts IP

Smarts IP is not polling dot3StatsDuplexStatus: .1.3.6.1.2.1.10.7.2.1.19 OID

Environment

VMware Smart Assurance - SMARTS

Resolution

To determine the correct duplex status, you can add the "DOT3-Duplex-Driver" into the Switch containment driver in the DISCOVERY_GENERIC.import file, as in the following:

GA_CompoundDriver::Containment-Generic-Switch-Driver {
    drivers = {
 {"Containment-Create-Interface-Driver", 10},
 {"Containment-Create-Port-IfDescr-Driver", 20},
 {"Containment-IfTable-Driver", 30},
 {"DOT3-Duplex-Driver", 40}    <-------------------------------- add this line
    }
    waitForCompletion = TRUE
}

When this is done, the driver will populate data out of ".1.3.6.1.2.1.10.7.2.1.19" # dot3StatsDuplexStatus MIB.

Additional Information

You could also set the DuplexAssumed parameter to TRUE in the Smarts AM discovery.conf configuration file, but this will not differentiate between full and half duplex switches, so it is not a complete workaround.
