date_range 13-Jan-21

arrow_backward

arrow_forward

This procedure shows how to change the parameters for a TDF gateway using maintenance mode at the [edit unified-edge gateways tdf gateway-name] hierarchy level.

The gateway must be in maintenance mode to change:

Maximum number of sessions
Maximum amount of memory and CPU utilization.

Before you change these gateway parameters using maintenance mode:

Make sure that this change has been coordinated with affected groups and users.
Make sure that this change is applied to the correct gateway type and name.

To configure maintenance mode for a gateway parameter change:

Verify the current status of maintenance mode for the gateway.

Under normal operating conditions, the service mode is Operational (that is, not in maintenance mode).

user@host> show unified-edge tdf gateway-name service-mode 

The service-mode option displays the information details about maintenance mode as well as status.

Maintenance Mode
   MM Active Phase - System is ready to accept configuration changes for all
                  attributes of this object and its sub-hierarchies. 
   MM In/Out Phase - System is ready to accept configuration changes only for
                  non-maintenance mode attributes of this object and 
                  its sub-hierarchies. 

Gateway Name		Service Mode

<gateway-name>	Operational

From configuration mode, place the gateway in maintenance mode.

content_copy zoom_out_map
[edit]
user@host# set unified-edge tdf gateway-name service-mode maintenance
user@host# commit

Verify that the gateway is in active maintenance mode where configuration changes are accepted for this object.

content_copy zoom_out_map
[edit]
user@host> show unified-edge tdf gateway-name service-mode 

The service-mode option displays the information details about maintenance mode as well as status.

                  its sub-hierarchies. 

Gateway Name		Service Mode

<gateway-name>	Maintenance - Active Phase

Note:

All subscribers serviced by the gateway must go to zero. You can wait for these conditions to be met, or use the clear command for the gateway to force these conditions.

Configure the threshold for the maximum amount of CPU that the TDF gateway can use as a percentage from 1 through 90.
```
[edit unified-edge gateways tdf gateway-name]
user@host# set cac cpu cpu-pct
```
Configure the maximum number of TDF subscriber sessions that may be running, expressed in thousands of sessions.
```
[edit unified-edge gateways tdf gateway-name]
user@host# set cac maximum-sessions max-sessions
```
Configure the threshold for the maximum amount of memory that the TDF gateway can use as a percentage from 1 through 90.
```
[edit unified-edge gateways tdf gateway-name]
user@host# set cac memory memory-pct
```

Exit maintenance mode and commit the changes.
