Status
Can be Valid or Invalid. Only communities with Valid status can access the DES-5016.
Communities with Invalid status cannot access the DES-5016.
SNMP Trap Manager Setting
Enables you to enter the IP addresses of Trap Managers. Traps are messages the DES-
5016 sends out to inform trap managers of events on the network. The DES-5016
generates traps and sends them to the network manager. Trap managers are special
network users who are given certain rights and access to oversee and maintain the
network. This feature is available only in D-View or by using other SNMP management
software.
You can specify which network managers may receive traps from the DES-5016 by
creating a list of IP Addresses of the authorized network managers.
Trap managers can receive the following trap types:
•
Cold Start
•
Authentication Failure
•
Link Change Event
Cold Start
Signifies that the DES-5016 has been powered up. Software settings are reconfigured and
hardware systems are rebooted. A cold start is different from a factory reset.
Authentication Failure
Signifies that an addressee (or manager/ user) on the DES-5016 is not a valid user of the
DES-5016 and may have entered an incorrect community name.
Link Change Event
Signifies that the link of a port has changed from link up to link down or vice versa.
