H3C Huawei switch usage overview of port and VLAN technologies (1)

How to Use H3C Huawei switches: about port and VLAN technology, this article describes QoS, VLAN technology, and switch port speed limit, port configuration, etc, the author gives a comprehensive introduction to all the relevant knowledge about how to use H3C Huawei switches.

H3C Huawei switch usage system information: this page is mainly used to display and configure some system parameters of the switch. The version number of the current software used by the Software Version switch. The MAC address of the vswitch. The IP address of the IP address switch. you can log on to the IP address in a Web browser to manage the device. The subnet mask of the subnet mask switch. The default value is 255.255.255.0.

How to Use H3C Huawei switches: the gateway address of the CIDR Block of the Gateway Switch, which can be used to remotely manage the switch. If you are not sure about the gateway address, ask the network administrator or retain the default configuration. Aging time: the aging time of the dynamic MAC address of the switch.

Recover/save configuration: the switch has an internal EEPROM to save the configuration information of the switch. Restore the default configuration to restore the default configuration of the switch and save it to the EEPROM. You must note that the user name, password, IP address, and other information will be restored to the factory configuration to avoid logon failure. After saving the current configuration Switch configuration, you must write the current configuration into the EEPROM to make the configuration still valid after the switch is restarted.

H3C Huawei switch usage, about restart: This page allows users to remotely restart the switch. If you need to maintain the current configuration after restarting the switch, save the configuration before restarting the switch. Software Upgrade: the software for upgrading a vswitch must enter the maintenance mode. Do not interrupt the upgrade process during this period. Otherwise, the upgrade may fail. If you do not upgrade the software in maintenance mode, you need to manually restart the switch.

Port Status: displays the port status of the vswitch. The name of the port corresponding to the port name. Click the port number to configure port properties. The actual port rate is displayed. If the port is not connected, it is displayed --. Full duplex mode, half duplex. If the port is not connected, it is displayed --.

The connection status shows whether the port is connected. If the port is not connected, it is displayed --. The traffic control status shows whether the port traffic control function is enabled. The port forwarding data status is displayed. If a port is disabled, data cannot be forwarded.

Configure port properties: configure the port properties of the vswitch. The name of the port corresponding to the port name. The port speed configured for the working rate. The value is self-negotiation, 10 M, and 100 M (ports 25 and 26 can also be configured as 1000 M ). Duplex Mode self-negotiation, full duplex, half duplex. Enable/disable configuring port forwarding data status. If a port is disabled, data cannot be forwarded. Configure the priority of the port. Configure the status of the port traffic control function.

Port aggregation: Port aggregation aggregates multiple ports to form one aggregation group to share the inbound/outbound load among the member ports, it also provides higher connection reliability. The policy adopted by the aggregation algorithm when selecting a link. For example, there are three methods for selecting a link based on SA (source MAC address): SA, DA, and SA + DA.

The name of the port corresponding to the port name. The port configured for a common group is not a group member. Set this port to a group member. Note: When creating a port aggregation, the aggregation port type should be set to the same, and the port working rate cannot be set to automatic, and the hundreds of megabytes of ports and Gigabit ports cannot be configured as the same aggregation group.

How to Use H3C Huawei switch port image: used to configure port image. Port image enables you to enable the port image function. The port name of the image. The name of the port corresponding to the port name. Normal port this port is not configured as the mirrored port. The name of the port to which the image is sent. The image direction can be configured as the mirror inbound port, mirror outbound port, and mirror inbound and outbound port.

H3C Huawei switch usage-Port Speed Limit: limits the total rate of outgoing or incoming packets. Broadcast storm suppression: When the broadcast traffic exceeds the value set by the user, the system discards the broadcast packets to suppress the broadcast storm and ensure the normal operation of network services.

VLAN Type Selection: The switch implements two types of VLAN: 802.1Q VLAN and port-based VLAN. The default status is 802.1Q VLAN. Because these two VLANs cannot coexist, type conversion will cause the previous VLAN settings to be cleared.
