Problems When Using an IP/IPX-based Management Application 6-5

The IP/IPX-based management application can no longer access the device. Check that Community-SNMP access is enabled, see “Configuring Local Security” on page 5-15.

Check that the port through which you are trying to access the hub has not been disabled. If it is enabled, check the connections and network cabling at the port. Try accessing the hub through a different port. If you can now access the hub, a problem with the original port is indicated. Re-examine the connections and cabling.

Possibly there is a network problem preventing you from accessing the hub over the network. Try accessing the hub through the console port, and reset the hub.
