These are the configuration commands of the H3C switch and are used to set the switch's system information, wireless LAN, multicast, IRF, DHCP, LLDP, system working mode, and cross-slot functions. I'll explain what each command does line by line, and if it's an abbreviation, I'll also give the full English form of the command. Please see the explanation below:
The dis cur command is an abbreviation for display current-configuration, which is used to display the current configuration information.
#version 7.1.070, release 7754p10 This command is used to display the software version number and release number of the switch.
The sysname a1-3f-sjzx-bgw-core command is used to set the system name of the switch, which is the identifier of the device.
The wlan global-configuration command is used to enter the Wi-Fi global configuration view, which is used to configure the Wi-Fi global parameters.
calibrate-channel self-decisive enable all command enables autonomous channel calibration for all radio units, enabling the radio unit to automatically select the optimal channel based on channel quality.
calibrate-bandwidth self-decisive enable is a command that enables autonomous bandwidth calibration for all radio units, enabling the radio unit to automatically select the optimal bandwidth based on channel quality.
The undo multicast forwarding-mode command is used to cancel the configuration of multicast mode and restore the default multicast mode, which is based on the multicast routing table.
IRF MAC-address persistent always command is used to configure the MAC address persistence function of the IRF (Intelligent Resilient Framework) so that the MAC address of the IRF does not change after the device is restarted.
IRF Auto-Update Enable This command is used to enable the IRF's auto-update feature, enabling IRF member devices to automatically synchronize the configuration of the master.
IRF auto-merge enable is a command that enables IRF auto-merge to enable IRF member devices to automatically recognize and join existing IRF topologies.
The undo IRF link-delay command is used to cancel the delay detection function of the IRF link and restore the default delay detection time, which is 0 ms.
IRF member 1 priority 32 This command is used to set the priority of IRF member device 1 to 32, the higher the priority, the more likely the device is to become the primary device.
IRF Member 2 Priority 10 This command is used to set the priority of IRF member device 2 to 10, the lower the priority, the more likely the device is to become a backup device.
DHCP Enable This command enables the Dynamic Host Configuration Protocol (DHCP) feature that enables the switch to assign IP addresses and other network parameters to connected hosts.
LLDP Global Enable This command is used to enable the Link Layer Discovery Protocol (LLDP) function, which enables the switch to discover and manage adjacent devices.
system-working-mode standard command is used to set the system working mode of the switch to standard mode, that is, all functions and features are supported.
The xbar chassis 1 load-balance command is used to set the load balancing mode of the cross-slot of chassis 1, that is, the optimal cross-slot is automatically selected according to the amount of traffic.
The xbar chassis 2 load-balance command is used to set the load balancing mode of the cross-slot of chassis 2, that is, the optimal cross-slot is automatically selected based on the amount of traffic.
The above is my explanation of the above**, I hope it will be helpful to you. Please like, comment, follow
