ipdevpoll plugins
This page really needs a standard way to write about plugins.
The following plugins exists for ipdevpoll:
ARP
- Collects ARP and NDP records for IPv4 and IPv6 respectivly.
- Uses IP-MIB for ARP and IPV6-MIB for NDP
- Tries CISCO-IETF-IP-MIB for Cisco ARP/NDP if either IP-MIB or IPV6-MIB returned 0 rows.
- Creates shadow objects from all found ARP/NDP records.
- Stores all shadow objects that does not exist in the database already. Ie: If there's a row with the same netboxid, ip, mac and end_time = 'infinity' the new record will not be stored.
- All existing records with end_time = 'infinity' that are not found on this run will be timed out, ie: end_time will be set to the current time.
CAM
- Collects dynamic CAM records for level 2 and level 3 devices.
- Uses community string indexing if it's needed for the netbox. Will also try community string indexing if we're not certain and there exists vlans on the box.
- Stores all new records in the database.
- If a record is not found, we set an end_time to the existing record and start counting misses (miss count).
- If the miss count exceeds the maximum (default 3) we consider the record closed.
- Closed records have end time != infinity and miss count == null.
- If however the record is found before the maximum miss count is exceeded, we reset miss count to 0 and end time to infinity.
DNS name
- Performs reverse DNS lookups on netbox IP addresses
- Generates events if there's a missmatch between the reverse DNS lookup and the stored sysname.
Interfaces
- Polls all interfaces from a given netbox.
- Compares collected list of interfaces to what's stored in the database.
- New interfaces are stored.
- If a interface in the database was not found on the netbox during this run, it is marked as missing (timestamped to the current time).
Prefix
- Collects IPv4 and IPv6 with prefixes using ipAddressTable from IP-MIB
- Fallback to ipAddrTable if no reply on ipAddressTable
- Tries CISCO-IETF-MIB (cIpAddressTable) if no reply on 'ipAddressTable'
TypeOID
- Retrieves sysObjectID from the netbox and compares it to what's stored in the database.
- The database table “type” is used to map sysObjectId to vendor and the netbox type.
Not implemeted: Posts an event if there's a missmatch between stored type and the retrieved type and updates the database.
Vlan
- Retrieves vlan from switches and stuff.
