Configuring Shelf-Controller Redundancy (APX 8000)

Configuring the APX 8000 for shelf-controller redundancy

admin> read redundancy REDUNDANCY read

admin> list [in REDUNDANCY] context = [ { } { } ]

primary-preference = no-preference

The following example shows how you can configure the Primary-Preference parameter to indicate a preference for the controller in the right shelf-controller slot to be elected primary:

admin> read redundancy REDUNDANCY read

admin> set primary-preference = right-controller-preferred

admin> write REDUNDANCY written

Note: Primary-Preference settings remain in effect after a reboot. For example, if the left controller is configured with a particular setting, after a reboot the left controller still retains that setting.

The Redundancy-Stats profile contains system-maintained statistical information about each controller. The statistical information for each controller is located in Context-Stats[1] or Context-Stats[2].

The following example shows how you can view the contents of the Redundancy-Stats profile:

admin> read redundancy-statsREDUNDANCY-STATS read

admin> list

[in REDUNDANCY-STATS]

context-stats = [ { monitoring secondary defer-to-running-primary no-function+

admin> list context 1

[in REDUNDANCY-STATS:context-stats[1]] state = monitoring

function = secondary

select-reason = defer-to-running-primary prior-function = no-function last-reboot = crash

fan = { 317834728 }

admin> list context 2

[in REDUNDANCY-STATS:context-stats[2]] state = monitoring

function = primary select-reason = communication-loss prior-function = no-function last-reboot = crash

fan = { 317838764 }

The Redundancy and Redundancy-Stats profiles are visible through SNMP.

Refer to the APX 8000/MAX TNT/DSLTNT Reference for additional information about the Redundancy and Redundancy-Stats profiles.
