Trusted Hosts

In its default state the ETEP management port accepts all packets from any host. The trusted host feature lets you restrict access by specifying the hosts that are allowed to communicate with the management port. When the trusted host feature is enabled, packets that are received from non-trusted hosts are discarded. An exception is SSH, which is a secure protocol. It is always allowed regardless of host.

Figure 107 Trusted host list

The ETEMS management station must be included in the trusted host list when the trusted hosts feature is enabled, and at least one trusted host must have HTTPS enabled. HTTPS (TLS) is required for ETEMS to ETEP communications.

If you enter the management station IP address incorrectly, ETEMS will be unable to communicate with the ETEP. To recover, you will need to log in to the CLI and issue the disable-trusted-hostscommand. See “Appliance Unreachable” on page 224 for more information.

ETKMSs must also be included in the trusted host list. The easiest way to ensure that your ETKMSs are included in the list is to add the ETKMSs in the ETEMS Appliance Manager before enabling the trusted host feature on the ETEP.

If you add a new ETKMS in ETEMS after the trusted host feature is enabled on the ETEP, you can add the ETKMS to its trusted host list in one of the following ways:

●Use the ETKMS in a policy definition in ETPM

●On each ETEP that is using the trusted host feature, clear the Enable Trusted Hosts checkbox and then select it again

In either case, you must push the new configuration to the ETEPs for the new trusted host list to become effective. Until you push the new configuration, the ETEP’s status is displayed as not equal in the ETEMS Appliance Manager.

The ETEP interacts with two types of hosts:

●Inbound hosts are the management station protocols used to communicate with the ETEP: HTTPS, ICMP, and SNMP.

●Outbound hosts receive packets initiated by the ETEP: SNMP trap hosts, syslog servers, and NTP server hosts.
