3-24
Since both High and Normal require bandwidth in excess of their guaranteed minimum, each
is allocated their guaranteed minimum. This leaves 40% of the bandwidth free to be assigned
on a priority basis. High has more priority than Normal, so it takes as much bandwidth as
needed. In this case it is 30%, which brings High up to 70%. This leaves 10% for Normal, which
is not enough. Traffic is buffered for a short period, and then dropped.
If at the same time Very High traffic is sent, this level immediately steals 20% from the lower
levels. In this case, 10% is taken from Normal, returning it to its minimum guaranteed level,
and 10% is taken from High.
Discovery protocols
The controller supports two protocols (LLDP and CDP) that provide a mechanism for devices
on a network to exchange information with their neighbors.
To these protocols, select Controller >> Network > Discovery protocols.
LLDP agents
For a complete discussion of all LLDP options, see Chapter 17: LLDP on page 17-1.
CDP
The controller can be configured to transmit CDP (Cisco Discovery Protocol) information on
the LAN and Internet ports. This information is used to advertise controller information to
third-party devices, such as CDP-aware switches. Network managers can retrieve this
information allowing them to determine the switch ports to which different controllers are
connected.
