Monitoring Resources
Viewing Information on Resource Usage
Usage Notes ■ A 1:1 mapping of internal rules to configured policies in the switch does

not necessarily exist. As a result, displaying current resource usage is the
most reliable method for keeping track of available resources. Also,
because some internal resources are used by multiple features, deleting
a feature configuration may not increase the amount of available
resources.
■ Resource usage includes resources actually in use or reserved for future
use by the listed features.
■ “Internal dedicated-purpose resources” include the following features:
• Per-port ingress and egress rate limiting through the CLI using
rate-limit in/out
• Per-port ingress and egress broadcast rate limiting through the CLI
using rate-limit bcast/mcast
• Per-port or per-vlan priority or DSCP through the CLI using qos priority
or qos dscp
• Per protocol priority through the CLI using qos protocol
■ For chassis products (for example, the 5400zl or 8212zl switches), ‘slots’
are listed instead of ‘ports’ with resources shown for all installed modules
on the chassis.
■ The “Available” columns display the resources available for additional
feature use.
■ The “IDM” column shows the resources used for RADIUS-based authen-
tication with or without the IDM option.
■ “Meters” are used when applying either ICMP rate-limiting or a QoS policy
with a rate-limit class action.
