vim is great, but just use .vimrc instead of settings in the source files. or if anyone cares that much, write up a sample one and add it to git.

App::Netdisco::SSHCollector::Platform::BigIP
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
Collect ARP entries from F5 BigIP load balancers. These are Linux boxes,
|
|
but feature an additional, proprietary IP stack which does not show
|
|
up in the standard SNMP ipNetToMediaTable.
|
|
|
|
These devices also feature a CLI interface similar to IOS, which can
|
|
either be set as the login shell of the user, or be called from an
|
|
ordinary shell. This module assumes the former, and if "show net arp"
|
|
can't be executed, falls back to the latter.

|
|
of the device. C<$ssh> is a Net::OpenSSH connection to the device.
|
|
