=head1 DESCRIPTION
|
|
|
|
Abstraction subclass for Cisco Catalyst 3550 Layer 2/3 Switches.
|
|
|
|
These devices run IOS but have some of the same charactersitics as the Catalyst WS-C family (5xxx,6xxx).
|
|
For example, forwarding tables are held in VLANs, and extened interface information
|
|
is gleened from CISCO-SWITCH-MIB.
|
|
|
|
For speed or debugging purposes you can call the subclass directly, but not after determining
|
|
a more specific class using the method above.
