The EMA provides the ability to view status and statistics across contexts. For example, it is possible to view trunk group status across all zones and address contexts. For large configurations, however, performance may be impacted when viewing status and statistics across contexts. This is especially true for configurations with more than 20 zones.
To address this problem,
Running this script disables all cross-context functionality forcing you to specify the object context before viewing status, statistics or configuration information for an object. For example, after running this script you will need to first select a specific address context and zone in order to view trunk group status or a list of trunk groups.
To disable cross-context queries, perform the following steps:
Enter the following command and press Enter:
/opt/sonus/ema/updateCrossContextDisabledValue.sh true
Log out of the redirection console and close it
Log out of the BMC.
If the
To re-enable cross context queries, follow the steps above substituting the following command with the one in step 5:
/opt/sonus/ema/updateCrossContextDisabledValue.sh false
