Monitoring Resources
Viewing Information on Resource Usage
Figure E1 shows the resource usage on a 3500yl switch configured for ACLs,
QoS, RADIUS-based authentication, ICMP, and other features. Note that the
switch is also configured for virus throttling and is either blocking or throttling
routed traffic with a high rate of connection requests.
In this example, the “Rules Available” column displays the resources available for additional feature use. The “Rules Used” columns
show that configured ACL, QoS, and other (for example, Management VLAN) resources, as well as the current blocking or throttling
of a client by the virus-throttling (VT) feature, all result in identical resource consumption on each port range in the switch. At the
same time, there is authenticated client usage of IDM resources on ports 25-48, and ICMP rate-limiting usage of different resource
levels on ports 1-24 and 25-48, and on slot A. The “IDM” column shows the rules used for RADIUS-based authentication with or
without the IDM option.

0 of 8 Policy Engine management resources used.
Key:
ACL = Access Control Lists; QoS = Host or application port QoS policies;
IDM = Identity Driven Management; VT = Virus Throttling;
ICMP = network ICMP rate limiting;
Other = Management VLAN, Remote Intelligent Mirror endpoints, DHCP Protection.
Resource usage includes resources actually in use, or reserved for future use by
the listed feature. Internal dedicated-purpose resources, such as port bandwidth
limits or VLAN QoS policies, are not included.
