=head1 SYNOPSIS
|
|
|
|
# Let SNMP::Info determine the correct subclass for you.
|
|
my $c1900 = new SNMP::Info(
|
|
AutoSpecify => 1,
|
|
Debug => 1,
|
|
# These arguments are passed directly on to SNMP::Session
|
|
DestHost => 'myswitch',
|
|
Community => 'public',
|
|
Version => 1
|
|
)
|
|
or die "Can't connect to DestHost.\n";
|
|
|
|
my $class = $c1900->class();
|
|
print "SNMP::Info determined this device to fall under subclass : $class\n";
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
Provides abstraction to the configuration information obtainable from a Catalyst 1900 device through SNMP.
|
|
See SNMP::Info for full documentation
|
|
|
|
Note that most of these devices only talk SNMP version 1, but not all.
|
|
|
|
For speed or debugging purposes you can call the subclass directly, but not after determining
|
|
a more specific class using the method above.

Return C<1>. Bulkwalk is turned off for this class.

|
=item $c1900->c1900_flash_status()
|
|
|
|
Usually contains the version of the software loaded in flash.

|
B<STAND-ALONE-ETHERNET-SWITCH-MIB::upgradeFlashBankStatus>
|

|
=item $c1900->os()
|
|
|
|
Returns 'catalyst'
|
|
|
|
=item $c1900->os_ver()
|
|
|
|
Returns CatOS version if obtainable. First tries to use
|
|
SNMP::Info::CiscoStats->os_ver() . If that fails then it
|
|
checks for the presence of $c1900->c1900_flash_status() and culls
|
|
the version from there.
|
|
|
|

Returns 'cisco' :)
