Default user name and password of the CX91x
The default user name and password of the BMC and onboard Ethernet switching plane of the CX91x are as follows: Default user name: root Default password: Huawei12#$ In some cases (such as serial port login and BIOS login), you only need to enter the password but do not need to enter the user name. The default user name and password of the FC switching plane (available only for CX911 and CX912) are as follows: Default user name: admin Default password: Huawei12#$

Powering off an E9000
Power off an E9000 as follows: 1. Power off the blades or switch modules in an E9000 chassis using the MM910 Web interface. For details, see http://support.huawei.com/ehedex/pages/DOC1000053358YEF0907R/08/DOC1000053358YEF0907R/08/resources/en/osca/smma_help_r2/it_osca_smma_900020.html. 2. Disconnect the E9000 power cable from the mains supply.

Standard spanning tree protocols used on S series switch
S series switches (except S1700 switches) support the following standard spanning tree protocols: 1. STP: Spanning Tree Protocol 2. RSTP: Rapid Spanning Tree Protocol, compatible with STP 3. MSTP: Multiple Spanning Tree Protocol, compatible with STP and RSTP By default, S series switches use MSTP. When running a command to set STP mode, you can select STP, RSTP, or MSTP. VLAN-Based Spanning Tree (VBST) is a Huawei proprietary spanning tree protocol, which sets up a spanning tree for each VLAN, so traffic in different VLANs can be forwarded through different spanning trees.
