5.3.2.1 Interface Name
The interface name is used to configure the SNMP Mib variable IfAlias in the IfXTable
element of the IF-MIB.
5.3.2.2 SFP Type
This display item indicates the type of SFP fitted. This value is read from the SFP device
itself and is a decode of the interface type bytes according to the SFP MSA definition.
Metrodata supplied SFP devices will indicate the SFP type, however some lower cost,
lower quality SFP devices may not be correctly programmed and will indicate
“UNKNOWN” as the device type cannot be determined.
If no SFP is fitted, this will show “NOT FITTED”
5.3.2.3 State
This setting defines the administrative state of the port and may be UP or DOWN. When
the state is DOWN, no alarm processing is performed. If an SFP is not fitted, it is
important to change this state to DOWN to prevent the SFP MAJOR alarm being
generated.
