Description: CPU-bound traffic MAC filtering for Ubiquoss switches, generating notifications when packets from specific MAC addresses are blocked
Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.
What Is UBQS-CPU-MAC-FILTER-MIB?
UBQS-CPU-MAC-FILTER-MIB is a Ubiquoss vendor MIB that manages CPU-bound traffic MAC address filtering on Ubiquoss switches, used to protect the switch's control-plane CPU from being overwhelmed by traffic from specific source MAC addresses. It exposes configuration objects for defining filtered/blocked MAC addresses along with a notification mechanism that fires when packets from a filtered MAC are blocked. Its monitoring value is security/software-protection oriented: it lets an operator confirm which MAC addresses are currently filtered from reaching the switch CPU and receive real-time alerts (via ubiCpuMacFilterMIBNotifications, implied by the Notifications/Conformance groups) when filtering rules are actively blocking traffic, indicating a potential attack or misbehaving host. It has no apparent dependency on standard IETF MIBs, defining its own object tree for this Ubiquoss-specific control-plane protection feature. It is deployed on Ubiquoss switches in networks where control-plane policing against MAC-flooding or spoofing attacks is required. Engineers can download the UBQS-CPU-MAC-FILTER-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in UBQS-CPU-MAC-FILTER-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.
Supported Devices
- Ubiquoss switch
Monitoring Examples
An operator would inspect the CPU MAC filter configuration objects under ubiCpuMacFilterMIBObjects to confirm which MAC addresses are currently blocked from reaching the switch's CPU. When a filter match occurs, a notification rooted at ubiCpuMacFilterMIBNotificationPrefix is generated, alerting the operator that traffic from a specific filtered MAC address was dropped, which could indicate an attempted control-plane attack or a misconfigured host flooding the switch.
What Can Be Monitored
- filtered/blocked MAC address list
- CPU-bound traffic block events
- control-plane protection status
