The notification contains the OmniSwitch IP Address/Hostname and OmniVista IP Address. Or Stellar AP does not have IoT Profiling enabled. |
IP Address Duplication | Notification sent when a Duplicate IP Address is noticed on the OmniSwitch. The notification contains the OmniSwitch IP Address/Hostname and duplicate IP Address. The notification proposes remediation action (QOS Policy) to block the traffic from duplicate IP Address. If a duplicate IP Address is an Essential IP Address (listed in the Essential_IP.csv file) or the corresponding MAC Address matches with an OmniSwitch device, the action is aborted. Once action is complete, a notification with a summary and log collection is sent. |
LinkAgg Down | Notification sent when a port is leaving Link Aggregate or when Link Aggregate is DOWN. The notification contains the OmniSwitch IP Address/Hostname and Aggregate ID/Port number. |
NAAS Licensing Issue | Notification sent when NAAS Licensing status is updated (switch entering into grace period or degraded mode). The notification contains the OmniSwitch IP Address/Hostname and the reason. |
Network Loop | When a Network Loop is suspected we increase the log verbosity of the task bcmd in case the Network Loop is confirmed a notification is sent with the OmniSwitch IP Address/Hostname and interface/port number. The notification proposes remediation action (interface/port admin-state disable) to stop the network loop. Log verbosity is set back to Info. Once the action is complete, a notification with a summary and log collection is sent. |
Network Storm: | Notification sent when a Traffic Storm is noticed on an OmniSwitch. This event is triggered when unexpected traffic (unknown unicast, multicast, broadcast) exceeds the flood-limit threshold. The notification proposes remediation action (interface/port admin-state disable) to stop the storm. Once the action is complete, a notification with a summary and log collection is sent. |
