E9000 troubleshooting

The simplest way to check the existence of a loop on an S series switch (except the S1700) is to check whether a MAC address flapping alarm exists on the switch. If the alarm exists, you can quickly locate the loop based on the information in the alarm. Run the display mac-address flapping record command to check whether MAC address flapping exists, or run the display trapbuffer command to check whether the alarm contains The mac-address has flap value or MAC move detected.

Power on an E9000 server as follows: ? If the E9000 chassis is not powered on, connect the power cables to the mains supply. The blades, switch modules, and management modules will be powered on with the chassis. ? If the chassis is powered on but the blades, switch modules, and management modules are not installed, install the modules. These modules will be automatically powered on after being installed. ? In routine maintenance, power on or off the blades or switch modules on the MM910 Web interface.

The MZ510 and MZ512 support Universal Multi-Channel (UMC), that is, multi-PF. Each physical port supports multiple physical functions (PFs), which divide a port into multiple independent logical channels. For details about related applications, see the NIC user guide.
