Description
The database server for
Sentriant AG, this process
is used to store endpoint
activity information until
it can be pushed to the
MS.
In DHCP static route
enforcement, this process
proxies endpoint Web
traffic to either the end-
user screens or to the
default gateway of the
ES.
Proxies requests from
802.1X switches to an
authentication server.
Provides file and printer
sharing services to clients
and assists in joining the
ES to the domain.
Responds to SNMP
requests from other
device.s
Enforcement Server Processes and Threads
Criticality Failure implications
High If this process is down, the
nac-es process is likely to go
down shortly thereafter.
High If this process is down in
DHCP static route enforcement
mode, endpoints in quarantine
cannot access resources
defined in Quarantine/guest
resources beyond the default
gateway of the ES. See
"Quarantine/guest resources"
on page 123 for more
information.
High If this process is down, switch
proxy requests are blocked at
the ES, and endpoints are
unable to authenticate to the
network.
High If this process is down, switch
proxy requests are blocked at
the ES, and endpoints will be
unable to authenticate to the
network.
Low- If this process is down, the
High system will no longer respond
to SNMP requests. Since these
requests are informational in
nature, the impact to
Sentriant AG is low, but the
impact to network operations
might be high.
