Description: Extreme Networks MIB for Server Load Balancing (SLB), managing virtual servers, real servers, and load balancing policies.
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 EXTREME-SLB-MIB?
EXTREME-SLB-MIB is an Extreme Networks vendor MIB for Server Load Balancing (SLB), covering the configuration and status of virtual servers, real (backend) servers, and load-balancing policies implemented on Extreme switching platforms. It exposes data about virtual server definitions, the pool of real servers behind them, and the health/weighting policies used to distribute traffic. Its monitoring relevance is chiefly software/service status: an operator can check whether real servers behind a virtual IP are marked up or down by the switch's health checks, an application/service-availability fault indicator rather than a hardware sensor reading. It implements Extreme's own SLB feature set on top of standard IP/TCP load-distribution concepts, with no explicit dependency on an external IETF load-balancing MIB noted in the available extract. It is typically deployed on Extreme switches acting as a Layer 4 load balancer in front of server farms in data-center environments. Engineers can download the EXTREME-SLB-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in EXTREME-SLB-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
- Extreme Networks Ethernet switch (Layer 4 load-balancing deployment)
Monitoring Examples
No specific object/table names were provided in the source extract for this MIB, so specific tables cannot be cited without invention. In general use, an administrator would check virtual-server and real-server status objects to confirm each backend server behind a load-balanced virtual IP is currently marked up, with a server reporting down indicating a failed health check and reduced backend capacity.
What Can Be Monitored
- virtual server configuration
- real server health/status
- load-balancing policy/weighting
