Brocade MLX Series and Brocade NetIron XMR Diagnostic Guide ...

2Management module diagnostics• You can allocate memory for more VLANs or virtual routing interfaces. By default, you canconfigure up to 512 VLANs and virtual routing interfaces on the router. Although this is thedefault maximum, the Brocade NetIron XMR and Brocade MLX series devices can support upto 4094 VLANs and 4095 virtual routing interfaces. (VLAN IDs 0 and 4095 are reserved.) Ifmany of your VLANs will have an identical configuration, you might want to configure VLANgroups. To learn more about VLAN groups and how to configure them, refer to the Brocade MLXSeries and NetIron Family Configuration Guide.Management module diagnosticsThe management modules control Brocade NetIron XMR and Brocade MLX series hardwarecomponents, run networking protocols, and provide the Real Time Operating System (RTOS).Each chassis requires one management module, and can accept a second module for redundancythat works in conjunction with the active management module. If the active management modulebecomes unavailable, the redundant management module automatically takes over the systemoperation, minimizing system downtime.Running management module diagnosticsYou can run diagnostics on the management modules to check if the devices needed for properoperation are accessible and in working order. The diagnostics for the Line Processor (LP) modulesbegin after the completion of diagnostics for the management processor (MP) modules, if the LPmodules are present in the chassis.MP module is considered to have passed the diagnostics if the result of all the checks is "Passed".If an MP or an LP does not pass the diag burn-in command, contact Brocade Technical Support forfurther assistance.NOTERemove the standby management module from the chassis before running the diagnostics. If thestandby management module is present, running the diagnostics on the interface module fails.To run diagnostics on management modules, perform the following steps.1. Reload the system and immediately press the B key repeatedly until the system boots intomonitor mode.2. Type boot os flash primary to enter the OS.The prompt will change from MP Monitor> to MP OS>.3. From the MP OS> prompt, enter diag burn-in, as shown in the following example.MP-1 OS>diag burn-inPCI access- Passed88E1145 PHY- PassedStorage Card- PassedM41T11 RTC- PassedFE (slot 0; FE 0; 0x11fe6000) access passed;FE (slot 0; FE 1; 0x11fe6000) access passed;FE (slot 0; FE 2; 0x11fe6000) access passed;FE (slot 1; FE 0; 0x11fe6000) access passed;FE (slot 1; FE 1; 0x11fe6000) access passed;24 Brocade MLX Series and Brocade NetIron XMR Diagnostic Guide53-1002426-02
