Check config Pair Group

Hi All,

 

 

An exteme new bie question...

 

I want to check how the two F5 boxes are configures in a pair.

 

 

In our network, we have two F5 boxes balancing load towards the processing machines. How can I check, how these both F5 boxes are working in a pair ACTIVE/ACTIVE Active/standby or any other configuration.

 

 

I have heard from seniors it is an Active/Passive configuration. But how can I confirm this and how to locate the active box.

 

 

Thx in advance.

    Hi,

     

     

    From the command line the prompt will show whether the unit is active, standby or inoperative. You can also run ps1 to get the same info. The GUI should show this as well in the top left corner. You can check for the configuration of what they should be in the GUI under System | Platform | High Availability (single unit or redundant pair) and System | High Availability | Redundancy Mode (active-standby or active-active).

    Hi Sunny,

    You can check F5-BIGIP-SYSTEM-MIB: 

    
/usr/share/snmp/mibs/F5-BIGIP-SYSTEM-MIB.txt

sysAttrFailoverUnitMask OBJECT-TYPE
        SYNTAX Integer32
        MAX-ACCESS read-only
        STATUS current
        DESCRIPTION
                "This data indicates whether the machine is active or standby.
                The value for this data could be 0, 1, 2, or 3.
                The values of 1 and 2 are only defined for an active-active installation.
                If two boxes are both active, value for unit 1 will be 1 and value for unit 2 will be 2.
                Otherwise, for active unit, this value is 3; for stand-by unit, this value is 0."
        ::= { sysGlobalAttr 19 }

    snmpwalk -c public localhost sysAttrFailoverIsRedundant

    F5-BIGIP-SYSTEM-MIB::sysAttrFailoverIsRedundant.0 = INTEGER: true(1)

    snmpwalk -c public localhost sysAttrFailoverUnitMask

    F5-BIGIP-SYSTEM-MIB::sysAttrFailoverUnitMask.0 = INTEGER: 3
