|
|
=head1 DESCRIPTION
|
|
|
|
SNMP::Info subclass to provide information for Cisco Catalyst series switches running CatOS.
|
|
|
|
This class includes the Catalyst 2920, 4000, 5000, 6000 (hybrid mode) families.
|
|
|
|
This subclass is not for all devices that have the name Catalyst. Note that some Catalyst
|
|
switches run IOS, like the 2900 and 3550 families. Cisco Catalyst 1900 switches use their
|
|
own MIB and have a separate subclass. Use the method above to have SNMP::Info determine the
|
|
appropriate subclass before using this class directly.
|
|
|
|
See SNMP::Info::device_type() for specifics.
|
|
|
|
Note: Some older Catalyst switches will only talk SNMP version 1. Some newer ones will not
|
|
return all their data if connected via Version 1.
|
|
|
|
For speed or debugging purposes you can call the subclass directly, but not after determining
|
|
a more specific class using the method above.
