For monitoring, I recommend using SNMP with MRTG or Cacti.
For bandwidth management, well, depending on the type of
Cisco switch, the QoS features available to the platform
will determine how granular you can manage the bandwidth.
More features translates to higher cost, as Cisco Catalyst
switches typically forward traffic (and perform QoS) in
In my experience, some QoS features in Cisco switches
(particularly the desktop models) may appear, but don't
actually take once configured.
Perhaps you may explain, further, what it is you are trying
to achieve. Are you trying to manage LAN bandwidth, or do
you want to use the switch to control the amount of
bandwidth your users get to the Internet?
Do you plan to use the switch as a Layer 3 device (so-called
Layer 3 switch)?
