Trusted Hosts

Trusted host configuration is used to prevent unauthorized access to the OLT. The trusted host portion of aaa is configured as follows.

System AAA Trusted Host Attributes

Attribute	Values	Default	Req	Description
Interface-name	String	N/A	Y	The interface name to apply the trusted host configuration to.
Enable-trusted-host	true \| false	false	N	Whether to enable trusted host. Enabling trusted host will block all access from any IP except for those explicitly listed in the configuration.
Trusted-hosts	List of strings	N/A	Y	The EMS must be a part of the list of trusted hosts or the OLT will become unmanageable by the EMS. IP addresses should be used rather than hostnames.
Enabled-icmp-destination-unreachable	true \| false	true	N	Whether to send back destination unreachable for unroutable packets.
Icmp-rate-limit	0..1000	0	N	Rate to limit destination unreachable packets to. Zero indicates that there is no rate limit.
Enable-group-icmp-echo-reply	true \| false	true	N	Whether to allow pings to the OLT. Default is ping is blocked. It is more secure not to reply to pings which reveal a targetable IP.
