Enabling Ports on Firewalls
If eSight is not in the same network segment as the NEs, upper-layer NMSs, SMS gateways, and mail servers, you must enable ports on firewalls before the commissioning.
Based on actual network plans, refer to the eSight Communication Matrix to enable the communication ports on firewalls between eSight and the NEs, SMS gateways, and mail servers.
