/********************************************
*
* RackTables 0.20.x snmpgeneric extension
*
* sync an RackTables object with an SNMP device.
*
* Should work with almost any SNMP capable device.
*
* reads SNMP tables:
* - system
* - ifTable
* - ifxTable
* - ipAddrTable (ipv4 only)
* - ipAddressTable (ipv4 + ipv6)
* - ipv6AddrAddress (ipv6)
*
* Features:
* - update object attributes
* - create networks
* - create ports
* - add and bind ip addresses
* - create as new object
* - save snmp settings per object (uses comment field)
*
* Known to work with:
* - Enterasys SecureStacks, S-Series
* - cisco 2620XM (thx to Rob)
* - hopefully many others
*
*
* Usage:
*
* 1. select "SNMP generic sync" tap
* 2. select your SNMP config (host, v1, v2c or v3, ...)
* 3. hit "Show List"
* 4. you will see a selection of all information that could be retrieved
* 5. select what should be updated and/or created
* 6. hit "Create" Button to make changes to RackTables
* 7. repeat step 1. to 6. as often as you like / need
*
*
* needs PHP 5
*
* TESTED on FreeBSD 9.0, nginx/1.0.12, php 5.3.10, NET-SNMP 5.7.1
* and RackTables <= 0.20.3
*
* (c)2015 Maik Ehinger <[email protected]>
*/
/****
* INSTALL
* just place file in plugins directory
*
* Increase max_input_vars in php.ini if not all ports were added on one run.
*
