Article ID: KB31811 KB Last Updated: 15 Jun 2017Version: 1.0
Summary:

This article describes how a system administrator can check if a system has been rebooted after enabling Enhanced Subscriber Management.

Symptoms:

On a fresh install of the Junos Subscriber Management build, the system must be rebooted according to Juniper's documentation on Configuring Junos OS Enhanced Subscriber Management.

Operating a system without a reboot may result in unexpected system behavior. How can a system administrator verify if the chassis rebooted or not at a later state?

Solution:

Configured Enhanced Subscriber Management  without system Reboot:

From Cli:

user@host> show system subscriber-management statistics
subscriber-management not enabled  <-- System reports that Subscriber Management is "not enabled"
command not supported​

From RE Shell:

% sysctl -a | grep enhance
net.enhanced_rpf_debug: 0
net.pfe.debug_ae_count_lag_enhanced: -1
net.pfe.debug_force_lag_enhanced: 0
net.disable_lag_enhanced: 0
net.enhanced_bbe_support: 2   <-- “2” indicates the system is not running Enhanced Subscriber Management
...

After System Reboot:

From Cli:

user@host> show system subscriber-management statistics
Session Manager started @ Thu Jun  1 09:59:32 2017
Session Manager cleared @ Thu Jun  1 09:59:32 2017
