Monitoring Resources
When Insufficient Resources Are Available
When Insufficient Resources Are
Available
The switch has ample resources for configuring features and supporting:
■
RADIUS-authenticated clients (with or without the optional IDM applica
tion)
■
Virus throttling and blocking on individual clients.
N o t e
If virus throttling is enabled on a port and a large amount of IPv6 traffic goes
through that port, the CPU resources may be used up. ProCurve recommends
that you do not enable virus throttling on any port that may receive large
amounts of IPv6 traffic.
If the resources supporting these features become fully subscribed:
■
The current feature configuration, RADIUS-authenticated client sessions,
and virus throttling instances continue to operate normally.
■
The switch generates an event log notice to say that current resources are
fully subscribed.
■
Currently engaged resources must be released before any of the following
actions are supported:
•
Configuration of new entries for QoS, ACLs, virus throttling, ICMP
rate-limiting, Management VLAN, DHCP snooping, dynamic ARP pro
tection, and remote-mirroring endpoint features.
•
Acceptance of new RADIUS-based client authentication requests.
N o t e
Failure to authenticate a client that presents valid credentials may indi
cate that insufficient resources are available for the features configured
for the client in the RADIUS server. To troubleshoot, check the event log.
•
Throttling or blocking of newly detected clients with a high rate of
connection requests (as defined by the current virus-throttling con
figuration).
The switch continues to generate event log notifications (and SNMP
trap notification, if configured) for new instances of high connection-
rate behavior detected by the virus-throttling feature.
