=head2 snapshot
Performs snmp walks from C<.1.3.6.1>, C<1.0.8802.1.1>, and C<1.3.111.2.802> on
the device and builds a data structure which SNMP::Info can use to mimic the
device. The structure is saved into the C<device_snapshot> database table.
Builds and saves a data structure which Netdisco can use to mimic the device
(if shared) and also browse the SNMP Objects in the web.
Optionally, pass a value to the C<-p> parameter (mnemonic: persist) and the
base64 encoded data will also be saved to L<NETDISCO_HOME/logs/snapshots/IP>
(where C<IP> is the canonical IP of the device passed). Netdisco will load
this for any pseudo device with the same canonical IP.
By default the command will gather Objects for web browsing. Use the C<-p>
parameter (mnemonic: persist) to save the cache at
L<NETDISCO_HOME/logs/snapshots/IP> (where C<IP> is the canonical IP of the
device). You can share the file and it can be used to create a realistic
pseudo device in another installation.

Optionally, pass a value to the L<-e> parameter (mnemonic: explore> and the
data is also saved into the Netdisco database for web browsing (under
Device->SNMP tab).
Optionally use the C<-e> parameter to request MIB Objects other than the
defaults. This parameter takes a comma-separated list and supports three
types of item: MIB names (the file name in netdisco-mibs), MIB vendor (in
netdisco-mibs, will load all the MIBs within), or SNMP::Info class (loads all
MIBs needed).

Note that to web browse the gathered SNMP data, you also first need to run
the C<loadmibs> command.
