What Is Dell-VRTX-JUMBOFRAMES-MIB?
Dell-VRTX-JUMBOFRAMES-MIB is a small Dell private MIB that configures jumbo frame (large MTU) support on the integrated switch ports of the Dell PowerEdge VRTX chassis. It exposes two scalar objects: the current jumbo frame status and the status that will take effect after the next device reset, since jumbo frame changes on many switches require a reload to apply. This is a configuration-status MIB useful for confirming that a pending jumbo frame change has actually been applied after a reboot — a mismatch between the current and post-reset status objects would explain unexpectedly fragmented or dropped large packets on storage/iSCSI traffic relying on jumbo frames. It is narrowly scoped to the VRTX switch module and has no dependency on external standard MIBs. It is deployed on Dell PowerEdge VRTX chassis where large-MTU traffic (e.g., SAN/iSCSI or vMotion-style traffic) requires jumbo frame support on the integrated switch. Network engineers evaluating or troubleshooting this functionality can download the Dell-VRTX-JUMBOFRAMES-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in Dell-VRTX-JUMBOFRAMES-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.
What Can Be Monitored
- current jumbo frame enable status
- jumbo frame status pending next reset
Supported Devices
- Dell PowerEdge VRTX chassis integrated switch module
Monitoring Examples
An admin would check rlJumboFramesCurrentStatus versus rlJumboFramesStatusAfterReset to confirm whether a jumbo frame configuration change has been applied or is still pending a chassis reload. A mismatch between the two objects after a maintenance window would explain why large iSCSI or backup packets are still being fragmented or dropped. Once the two objects match, the admin can confirm the intended MTU policy is fully active on the switch module.
