With the Cisco UGM Configure Administrative States option, you can:
Remove an object (T1, E1, E1 combination card, T3, or T3 combination card) from service for maintenance with a minimum of customer impact (Graceful Shutdown).
Place the object back in service after maintenance (Accept Traffic).
Note References to E1 and T3 cards also include the E1 combination and
T3 combination cards.
The Object List contains the selected (root) object and its immediate children.
Initial dialog display fields are blank—not "Unknown." After a Configure Administrative State action has occurred, the fields retain their values until the next action for that object. The dialog fields show information from a previous action.
All dialog fields are logged (at INFO level); they are not just Progress Information.
If a Configure Administrative State action is in progress at the time of Cisco UGM termination, the action is not restarted at the time of a Cisco UGM restart. A "Graceful Shutdown interrupted" or "Accept Traffic interrupted" alarm is raised instead. These alarms are visible in the Event Browser and must be manually cleared.
Busyout does not terminate existing calls; instead, busyout allows existing calls to be completed and prevents any new calls from being established on the object.
Busyout phases out all DS0 operation on the card. When no active DS0s remain, the T1, E1, and/or T3 controllers (as applicable) on the card are shut down.
Note When you start this function, make sure that no other configuration
activity is in progress for the selected card or for its host chassis.
You can Accept Traffic on a selected card object in the locked state (resulting from a prior Graceful Shutdown action that was previously performed for this object).
By doing so, you can either configure the object to start receiving calls, or undo the effect of a graceful shutdown. The object is now in service.
Accept Traffic activates all T1, E1, and T3 controllers on the card (including those that may have been shut down by means other than the Graceful Shutdown method). Use this Accept Traffic method to activate T1, E1, and T3 controllers that are "down."
This section describes processing times associated with Configure Administrative State actions:
The dialog display fields are updated every 10 seconds.
After you click Accept Traffic, allow approximately 60 seconds for the card to power up.
Allow approximately 40 seconds for the T1, E1, and T3 controllers (as applicable) to start after you clickAccept Traffic.
When you click Graceful Shutdown, the number of active DS0s must drop to 0 before the shutdown begins. This processing time is difficult to anticipate.
Note The number of active DS0s drops to 0 if all calls terminate
on their own, ports are disconnected, or the card is removed
from the chassis.
The Configure Administrative State dialog fields are updated every 10 seconds; only the last update for a field is visible in the dialog. However, all display field updates appear in the Action Report.
The Action Report appears either because an action is complete or was interrupted.
The maximum number of characters in the report is limited to approximately 500,000.
The report is always timestamped, even if the report is "full."
When you shut down an object, it and all its descendants in the Physical hierarchy (except Universal ports in combination cards) are shut down as well.
Once initiated, you cannot cancel Graceful Shutdown. It must run to completion.
You cannot shut down T1, E1, and T3 controllers in loopback mode.
At a given time, you can perform only one Configure Administrative State action.
If you perform a Graceful Shutdown action on a Cisco AS5350 or AS5400 device, you cannot enter the Accept Traffic command.
The reason for this is that the busyout command is followed by removal of power to the card; the card is logically removed from the chassis; an OIR trap is issued. Since the card is removed from Physical View, the Accept Traffic action has no object to act on.
As a workaround, manually remove or insert the card into the chassis to start discovery, or enter the no busyout <slot> IOS command to the device.
Step 1 In the Map Viewer, select an object in the Physical hierarchy.
Step 2 Right-click the object and select Configure Administrative State.
