Configuring Shelf-Controller Redundancy (APX 8000)
Obtaining status information about redundant shelf controllers
disrupted and then reestablished, the uptime command reports the time elapsed since the
secondary controller reestablished communications with the primary.
The uptime command does not report the version number of code used by the controllers, but
instead reports the primary or secondary status of each controller. The code version is obtained
with the version command.
The following example shows the uptime command entered on the primary controller. The
-a option displays the up time for all slot cards.
admin> uptime -a
06:28:41
{ shelf-1 slot-3 } 8t1-card 0 days 00:08:53 8.0
{ shelf-1 slot-12 } hdlc2-card 0 days 00:08:53 8.0
{ shelf-1 slot-16 } csmx-card 0 days 00:08:53 8.0
{ shelf-1 slot-19 } hdlc2-card 0 days 00:08:53 8.0
{ shelf-1 slot-23 } csmx-card 0 days 00:08:53 8.0
{ shelf-1 slot-32 } hdlc2-card 0 days 00:08:53 8.0
{ shelf-1 slot-34 } 4ether2-card 0 days 00:08:53 8.0
{ shelf-1 left-controller } [...] 0 days 00:40:37 ( SECONDARY )
{ shelf-1 right-controller } [...] 0 days 00:41:21 ( PRIMARY )
The following example shows the uptime command entered on the secondary controller:
admin> uptime -a
06:28:26
{ shelf-1 left-controller } [...] 0 days 00:40:37 ( SECONDARY )
{ shelf-1 right-controller } [...] 0 days 00:41:21 ( PRIMARY )
Viewing controller status
The show command reports the communications status of the primary and secondary
controllers and indicates which controller (left or right) is the primary and secondary shelf
controller.
When the show command is entered on either the primary or secondary shelf controller, UP is
reported for the other controller’s status if the current controller is able to communicate with
the other controller. DOWN is displayed if the other controller is present but not communicating
with the current controller. If the other controller is not present, the status of that controller is
reported as ABSENT with the show -a command.
The following example displays the show command entered on the primary controller, when
the right controller is primary:
admin> show
Controller { right-controller } ( PRIMARY ):
{ left-controller ) UP ( SECONDARY )
{ shelf-1 slot-1 0 } DOWN ether3-card
{ shelf-1 slot-3 0 } UP 8t1-card
{ shelf-1 slot-12 0 } UP hdlc2-card
{ shelf-1 slot-16 0 } UP csmx-card
{ shelf-1 slot-19 0 } UP hdlc2-card
{ shelf-1 slot-23 0 } UP csmx-card
{ shelf-1 slot-32 0 } UP hdlc2-card
{ shelf-1 slot-34 0 } UP 4ether2-card
