getInterfaceInfoFromIfLabel

public static Map<String,String> getInterfaceInfoFromIfLabel(Connection conn,
                                                             int nodeId,
                                                             String ifLabel)
                                                      throws SQLException

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

Parameters:

conn - Database connection

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.

getInterfaceInfoFromIfLabel

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

Return a map of useful SNMP information for the interface specified by the nodeId and ifLabel. Essentially a "decoding" algorithm for the ifLabel. Overloaded method which first obtains a database connection from the vault.

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.

Throws:

SQLException

getIfLabel

public static String getIfLabel(int nodeId,
                                String ipAddr)
                         throws SQLException

Throws:

SQLException

getIfLabelfromIfIndex

public static String getIfLabelfromIfIndex(int nodeId,
                                           String ipAddr,
                                           int ifIndex)
                                    throws SQLException,
                                           NumberFormatException

Throws:

SQLException

NumberFormatException

getIfLabel

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