 backend poller, as this can highlight broken topology.

-Default: C<5000>
+Value: Number. Default: C<5000>.
 
 Port which the web server listens on. Netdisco comes with a good pre-forking
 web server, so you can change this to C<80> if you want to use it directly.
 However the default is designed to work well with servers such as Apache in
 reverse-proxy mode.

+Base directory in which to find C<mibdirs>. This is where C<netdisco-deploy>

+   - foundry
+
+=head3 C<community>
+
+Value: List of Strings. Default: C<public>.
+
+A list of read-only SNMP community strings to try on each device. The working
+community will be cached in the database.
+
+=head3 C<community_rw>
+
+Value: List of Strings. Default: C<private>.
+
+A list of read-write SNMP community strings to try on each device. The working
+community will be cached in the database.
+
+=head3 C<snmpver>
+
+Value: C<1|2|3>. Default: 2.
+
+Version of the SNMP protocol used when connecting to devices.
+
+=head3 C<snmptimeout>
+

+
+Micro-seconds before connection retry in L<SNMP::Session>. 1000000
+micro-seconds = 1 second.
+
+=head3 C<snmpretries>
+
+Value: Number. Default: 2.
+
+Number of times to retry connecting to a device before giving up.
+
+=head3 C<discover_no>
+
+Value: List of Network Identifiers. Default: Empty List.
+
+IP addresses in the list will not be visited during device discovery. You can
+include hostnames, IP addresses and subnets (IPv4 or IPv6) in the list.
+
+=head3 C<discover_only>
+
+Value: List of Network Identifiers. Default: Empty List.
+
+If present, device discovery will be limited to IP addresses matching entries
+in this list. You can include hostnames, IP addresses and subnets (IPv4 and
+IPv6).
+
+=head3 C<discover_no_type>
+
+Value: List of Strings. Default: None.
+
+Place a regular expression pattern here to exclude the discovery of certain
+devices based on the CDP/LLDP device type information. Good for excluding a
+whole device class like lightweight access points or IP phones that have CDP
+but don't talk SNMP
+
+=head3 C<macsuck_all_vlans>
+
+Value: Boolean. Default: C<false>.
+
+Set to macsuck all VLANs, not just the ones that are being used on ports.
+This is a debug option. Set this if you think that the option of not
+macsucking VLANs that aren't in use on device ports is some how interfering.
+
+=head3 C<macsuck_no_unnamed>
+
+Value: Boolean. Default: C<false>.
+
+Set to true to skip macsuck-ing on VLANs which have no name set. This option
+may be useful on Cisco Catalyst family devices where ports are a member of a
+VLAN which is not defined in the VLAN database.
+
+=head3 C<macsuck_bleed>
+
+Value: Boolean. Default: C<false>.
+
+Set to true will let nodes accumulate on uplink ports without topology
+information. This is a debug option to help you figure out your topology and
+generally should not be set.
+
+=head3 C<store_wireless_client>
+
+Value: Boolean. Default: C<true>.
+
+Set to false to skip the wireless client information gathering. This is
+captured at macsuck time, so if you aren't using the information you can skip
+it.
+
+=head3 C<ignore_interfaces>
+
+Value: List of Strings. Default:
+
+ ignore_interfaces:
+   - EOBC
+   - unrouted VLAN
+   - StackPort
+   - Control Plane Interface
+   - SPAN (S|R)P Interface
+   - StackSub
+
+If present, device ports matching any of the items in this list will be
+ignored by the discovery process. Note this may have side effects - connected
+devices and nodes on those ports will in turn also not be discovered.
+
+=head3 C<ignore_private_nets>
+
+Value: Boolean. Default: C<false>.
+
+Set to true to ignore device interfaces that are part of private nets (RFC
+1918).
+
+=head3 C<reverse_sysname>
+
+Value: Boolean. Default: C<false>.
+
+Turn this on to have Netdisco do a reverse lookup of the device C<sysName.0>
+field to use as the management IP address for a device.
+
+=head3 C<vlanctl>
+
+Value: Boolean. Default: C<false>.
+
+Set to true to allow Netdisco to be able to change the default VLAN on an
+interface.
+
+=head3 C<portctl_nophones>
+
+Value: Boolean. Default: C<false>.
+
+Set to true to make sure an IP Phone port never can be turned off/on.
+
+=head3 C<portctl_vlans>
+
+Value: Boolean. Default: C<false>.
+
+Set to true to allow Netdisco to be able to disable VLAN trunk interfaces.
+
+B<EXTREMELY VERY DANGEROUS>: Turning off a VLAN trunk link could take out most
+of your network.
+
+=head3 C<portctl_uplinks>
+
+Value: Boolean. Default: C<false>.
+
+Set to true to allow Netdisco to be able to disable Uplinks. (Router
+Interfaces too)
+
+B<EXTREMELY VERY DANGEROUS>: Turning off uplinks will take out chunks of your
+network.
+
+=head3 C<no_port_control>
+
+Value: Boolean. Default: C<false>.
+
+Set to true to disable globally support for Port Control. Mainly useful for
+development to suppress web frontend job queue callbacks.
+
 =head2 Backend Daemon
 
+=head3 C<workers>
+
+Value: Settings Tree. Default:
+
+ workers:
+   interactives: 2
+   pollers: 2
+   sleep_time: 5
+
+Control the activity of the backend daemon with this configuration setting.
+
+C<interactives> and C<pollers> sets how many workers are started for
+interactive jobs (port control) and polling jobs (discover, macsuck, arpnip)
+on this node, respectively. Other nodes can have different settings.
+
+C<sleep_time> is the number of seconds between polling the database to find
+new jobs. This is a balance between responsiveness and database load.
+
+=head3 C<housekeeping>
+
+Value: Settings Tree. Default: None.
+
+If set, then this node's backend daemon will schedule polling jobs (discover,
+macsuck, arpnip, etc) in the central database. It's fine to have multiple
+nodes scheduling work for redundancy (but make sure they all have good NTP).
+
+Note that this is independent of the Pollers configured in C<workers>. It's
+okay to have this node schedule housekeeping but not do any of the polling
+itself (C<pollers: 0>).
+
+Work can be scheduled using C<cron> style notation, or a simple weekday and
+hour fields (which accept same types as C<cron> notation). For example:
+
+ housekeeping:
+   discoverall:
+     when: '0 9 * * *'
+   arpwalk:
+     when:
+       min: 30
+   macwalk:
+     when:
+       hour: '*/2'

+
+Value: String. Default: C<UTF-8>.
+

+

+
+Value: Boolean. Default: C<false>.
+
+Should warnings be considered as critical errors?
+
+=head3 C<show_errors>
+
+Value: Boolean. Default: C<false>.
+
+Whether to show a stack trace when an error is caught in the web frontend.
+
+=head3 C<engines>
+
+Value: Settings Tree.
+
+Useful for overriding the Template Toolkit settings, if you want.
+

+
+Value: String. Default: C<main>.
+
+Don't touch this.
+
+=head3 C<plugins>
+
+Value: Settings Tree.
+
+Useful for overriding the Database configuration, but only if you know what
+you're doing.
+
+=head3 C<session>
+
+Value: String. Default: C<YAML>.
+
+How to handle web sessions. Default is to store on disk so they can be shared
+between multiple web server processes (although it's slower).
+
+=head3 C<template>
+
+Value: String. Default: C<template_toolkit>.
+
+Which engine to use for templating in the web frontend. Don't touch this.
+
+=head3 C<route_cache>
+
+Value: Boolean. Default: C<true>.
+
+Whether to build a route cache for web requests, for better performance.
+
+=head3 C<appname>
+
+Value: String. Default: C<Netdisco>.
+
+Don't touch this.
