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
Vlan
