The Security IP list (if used) does not contain the IP address of your management station.

From the SNMP Manager Configuration screen, make sure that security IP list or Management IP Station list has the IP address of your management station.

The internal switch processor port (meant for supporting switch management interfaces) and the port to which you have connected to access the switch from the Telnet, Web, or SNMP interfaces are not in the same VLAN.

Make sure that the Management VLAN ID on the Switch IP Settings screen is the same as the VLAN ID of the port that is trying to make the Telnet, Web, or SNMP connection. If not, change it to match.
