Method Detail

getInterfaceInfoFromIfLabel

public static Map<String,String> getInterfaceInfoFromIfLabel(int nodeId,
                                                             String ifLabel)

Return a map of useful SNMP information for the interface specified by the nodeId and ifLabel. Essentially a "decoding" algorithm for the ifLabel.

Parameters:

nodeId - Node id

ifLabel - Interface label of format: -

Returns:

Map of SNMP info keyed by 'snmpInterface' table column names for the interface specified by nodeId and ifLabel args.

Throws:

SQLException - if error occurs accessing the database.

getIfLabels

public static String[] getIfLabels(int nodeId)
                            throws SQLException

Get the interface labels for each interface on a given node.

Parameters:

nodeId - a int.

Returns:

an array of String objects.

Throws:

SQLException - if any.

getIfLabel

public static String getIfLabel(int nodeId,
                                String ipAddr)

getIfLabel

Parameters:

nodeId - a int.

ipAddr - a String object.

Returns:

a String object.

getIfLabelfromIfIndex

public static String getIfLabelfromIfIndex(int nodeId,
                                           String ipAddr,
                                           int ifIndex)

getIfLabelfromIfIndex

Parameters:

nodeId - a int.

ipAddr - a String object.

ifIndex - a int.

Returns:

a String object.

getIfLabelfromSnmpIfIndex

public static String getIfLabelfromSnmpIfIndex(int nodeId,
                                               int ifIndex)

Return the ifLabel as a string for the given node and ifIndex. Intended for use with non-ip interfaces.

Parameters:

nodeId - a int.

ifIndex - a int.

Returns:

String

getIfLabel

public static String getIfLabel(String name,
                                String descr,
                                String physAddr)

getIfLabel

Parameters:

name - a String object.

descr - a String object.

physAddr - a String object.

Returns:

a String object.
