Hi to all,
our old friend ACS has a clear distinction between management process and authentication runtime:
ACS/admin# show application status acs
ACS role: PRIMARY
Process 'database' running
Process 'management' running
Process 'runtime' running
Process 'adclient' running
Process 'ntpd' running
Process 'view-database' running
Process 'view-jobmanager' running
Process 'view-alertmanager' running
Process 'view-collector' running
Process 'view-logprocessor' running
This means that if management interface has to be restarted aaa requests are still handled during mgt process restart.
Now giving at look at ISE things seems pretty different:
ISE-TO-CVL-SVIL/admin# show application status ise
ISE PROCESS NAME STATE PROCESS ID
--------------------------------------------------------------------
Database Listener running 623
Database Server running 41 PROCESSES
Application Server running 24687
Profiler Database running 3298
AD Connector running 5969
M&T Session Database running 3211
M&T Log Collector running 5635
M&T Log Processor running 5581
Certificate Authority Service running 5537
SXP Engine Service disabled
pxGrid Infrastructure Service disabled
pxGrid Publisher Subscriber Service disabled
pxGrid Connection Manager disabled
pxGrid Controller disabled
Identity Mapping Service running 5862
but this output
ISE/admin# show ports | begin 24687
Process : jsvc.exec (24687)

shows that in ISE jsvc.exec process manages both portals/mgt interfaces (10.16.168.251:8443, :::443) and radius sockets ( 10.16.168.251:1812, 172.20.38.100:1812, 10.16.168.251:1813, 172.20.38.100:1813).
So my question is: what does happen when an admin certificate has to be installed renewed on ISE? On ACS we get a mgt interface restart with no aaa traffic disruption, has everyone information about aaa traffic when ISE application server is restarting?.
