System Monitoring For Errors (Nores, Err, Nospt) - Allied Telesis SwitchBlade x3100 Series Manual

Classifier Management

6.3.2.7 System Monitoring for Errors (NORES, ERR, NOSPT)

When creating classifiers, the user should consider all configuration guidelines, restrictions and limitations,
some of which are described in previous sections. The CLI provides outputs that help the user understand a
classifier configuration and why a certain command was accepted or rejected. These are explained below.
6.3.2.8 Classifier Resources Exceeded (NORES)
The system will generate a warning message informing the user if or when classifier resource capacity or capa-
bilities have been exceeded on the interface(s) impacted by the provisioning change. The user should investigate
classifier-related provisioning, such as IGMP, DHCPRELAY, VLAN (for per-VLAN UFO and HVLAN), EPSR,
INTERFACE (TAGALL option for HVLAN), ACCESSLIST, and CLASSIFIER to determine the reason for the
message.
When resources are exceeded on the interface(s), all user-created classifiers are set on the
Note:
interface(s) to NORES. (Internal-created classifiers persist.)
Exceeding classifier resources raises a NORES alarm (Classifier Resource Failed). An example of setting the
NORES alarm is illustrated below.
