ExtremeWare EPICenter Software Installation and User Guide A-7
Alarm System
Problem: Created a new protocol in VLAN Manager, but the protocol does not appear
on any switch.
When a new protocol is created, it is stored in the EPICenter database. EPICenter only
creates the protocolona switch when thenew protocol is used by a VLAN on that switch.
Problem: Can only access one of the IP addresses on a VLAN configured with IP
multinetting.
EPICenter does not currently support IP multinetting.
Problem: Configuration fails when attempting to configure a VLAN with a modified
protocol definition.
EPICenter does not have a mechanism to modify protocols. When a VLAN is configured
through EPICenter to use a protocol that does not exist on the switch, the protocol is first
createdonthe switch. However, if aprotocolwith the same name buta differentdefinition
already exists on the switch, the operation will fail.
Problem: An untagged port has disappeared from its VLAN.
Check to see if the port has been added as an untagged port to a different VLAN. In
EPICenter, adding an untagged port to a VLAN automatically removes the port from its
previous VLAN if the port was an untagged port, and the new and old VLANs used the
same protocol.This is different behavior from the ExtremeWare CLI, where you mustfirst
delete the port from the old VLAN before you can add it to the new VLAN.
Alarm System
Problem: Device is in a fault state that should generate a trap, and an alarm is
defined to detect it, but the alarm does not appear in the EPICenter Alarm Log.
There are several possible reasons this can occur. Check the following:
• Make sure that the alarm is enabled.
• Check that the device is in your alarm scope.
• Check that SNMP traps are enabled on the device.
