HP Aruba JL253A - Usage Notes for Show Resources Output; When Insufficient Resources Are Available

◦ Mirror policies per VLAN through the CLI using monitor service
◦ Jumbo IP-MTU
• When the following features are configured per-port, resource usage is applied only to the slot or port group on
which the feature is configured:
◦ ACLs or QoS applied per-port or per-user through RADIUS authentication
◦ ACLs applied per-port through the CLI using the ip access-group or ipv6 traffic-filter
commands
◦ QoS policies applied per port through the CLI using the service-policy command
◦ Mirror policies applied per-port through the CLI using the monitor all service and service-
policycommands
◦ ICMP rate-limiting through the CLI using the rate-limit icmp command
Usage notes for show resources output
• 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 or per-VLAN priority or DSCP through the CLI using qos priority or qos dscp
◦ Per protocol priority through the CLI using qos protocol
• The "Available" columns display the resources available for additional feature use.
• The "IDM" column shows the resources used for RADIUS-based authentication.
• "Meters" are used when applying either ICMP rate-limiting or a QoS policy with a rate-limit class action.
When insufficient resources are available
The switch has ample resources for configuring features and supporting RADIUS-authenticated clients (with or
without the optional IDMapplication).
If the resources supporting these features become fully subscribed:
• The current feature configuration, RADIUS-authenticated client sessions, and VT instances continue to
operate normally.
• The switch generates anevent log notice to say that current resources are fully subscribed.
• Currently engaged resources must be released before any of the following actions are supported:
◦ Modifying currently configured ACLs, IDM, VT, and other software features, such as Management VLAN,
DHCP snooping, and dynamic ARP protection.You can modify currently configured classifier-base QoS and
