Description: Brocade Foundry Layer 3 switch routing group MIB providing routing table, interface, and protocol management for FastIron L3 switching platforms.

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 FOUNDRY-SN-RT-L3-SWITCH-GROUP-MIB?

FOUNDRY-SN-RT-L3-SWITCH-GROUP-MIB is a Brocade (formerly Foundry Networks) vendor MIB for Layer 3 routing management on FastIron L3 switching platforms, covering IP routing, ARP cache control, IP filtering (ACLs), and diagnostic tools like traceroute. It exposes configuration objects for IP filter rules (source/destination address and mask, protocol, action) as well as operational/diagnostic objects for clearing the ARP and IP route caches and running traceroutes. Rather than passive counters, several of these objects (snRtClearArpCache, snRtClearIpCache, snRtIpTraceRoute) are actionable controls that double as software-status tools, letting an administrator verify and reset the routing software's cached state. It is a vendor-specific extension of the Foundry/Brocade enterprise MIB tree, layered on top of standard IP routing concepts. It is used on Brocade/Foundry FastIron Layer 3 switches where network engineers manage ACL-based filtering and need SNMP-based diagnostic tools for troubleshooting routing issues. Engineers can download the FOUNDRY-SN-RT-L3-SWITCH-GROUP-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in FOUNDRY-SN-RT-L3-SWITCH-GROUP-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.

Monitoring Examples

An engineer could use snRtIpFilterTable entries (snRtIpFilterSourceIp, snRtIpFilterDestIp, snRtIpFilterAction) to audit which IP filter/ACL rules are active on the switch and confirm intended traffic is permitted or denied. Triggering snRtIpTraceRoute via snRtIpTraceRouteGeneral allows remote path verification without console access, useful when diagnosing an unreachable downstream network. Invoking snRtClearArpCache or snRtClearIpCache remotely can resolve stale-entry routing problems after a topology change.
