Usually these boxes do not allow running single commands via SSH but just a custom/restricted shell.

What happens when you try to invoke the remote command with SSH as in...? 

$ /usr/local/bin/ssh auto_config@management show vlan

If it doesn't work, your best option will probably be to use Expect (alone, combined with Net::OpenSSH or via Net::SSH::Expect).

For simple cases, usually this also works: 

my $out = $ssh->capture({stdin_data => "show vlan\n"});
print "output: $out"
