As expertise advances, networking switches have turn out to be an integral a part of the IT infrastructure. They play a vital function in directing communication on the community and making certain easy, environment friendly knowledge switch. It’s essential for IT professionals to be accustomed to primary command configurations for common change manufacturers like Huawei, H3C, Ruijie, and Cisco. This complete information, dropped at you by Router-switch.com, the main international provider of community {hardware} and software program options, will stroll you thru the fundamentals of change command configuration.
To make it clear to everybody, every line of code has an evidence.
I. Fundamental Command Configuration for Huawei Switches
Understanding the Huawei change command configuration begins with a agency grasp of the system view command and the function of VLAN configuration.
Create VLAN:
<Quidway> // Consumer view, that’s, run instructions beneath Quidway mode.
<Quidway>system-view // Enter configuration view
[Quidway] vlan 10 // Create vlan 10 and enter vlan10 configuration view. If vlan10 exists, enter vlan10 configuration view instantly.
[Quidway-vlan10] give up // Return to configuration view
[Quidway] vlan 100 // Create vlan 100 and enter vlan100 configuration view. If vlan100 exists, enter vlan100 configuration view instantly.
[Quidway-vlan100] give up // Return to configuration view
Add ports to the VLAN:
[Quidway] interface GigabitEthernet2/0/1 (10G optical port)
[Quidway- GigabitEthernet2/0/1] port link-type entry // Outline port transmission mode
[Quidway- GigabitEthernet2/0/1] port default vlan 100 // Add port to vlan100
[Quidway- GigabitEthernet2/0/1] give up // Return to configuration view
[Quidway] interface GigabitEthernet1/0/0 // Enter the configuration view of the primary Gigabit Ethernet port on the slot 1. 0 represents port 1.
[Quidway- GigabitEthernet1/0/0] port link-type entry // Outline port transmission mode
[Quidway- GigabitEthernet2/0/1] port default vlan 10 // Add this port to vlan10
[Quidway- GigabitEthernet2/0/1] give up
Add a number of ports to the VLAN
<Quidway>system-view
[Quidway]vlan 10
[Quidway-vlan10]port GigabitEthernet 1/0/0 to 1/0/29 // Add ports 0 to 29 to vlan10
[Quidway-vlan10]give up
Swap Configures IP Tackle
[Quidway] interface Vlanif100 // Enter vlan100 interface view, which is totally different from the place vlan 100 command enters.
[Quidway-Vlanif100] ip tackle 119.167.200.90 255.255.255.252 // Outline vlan100 administration IP layer 3 change gateway route
[Quidway-Vlanif100] give up // Return to view
[Quidway] interface Vlanif10 // Enter vlan10 interface view, which is totally different from the place vlan 10 command enters.
[Quidway-Vlanif10] ip tackle 119.167.206.129 255.255.255.128 // Outline vlan10 administration IP layer 3 change gateway route
[Quidway-Vlanif10] give up
Configure the default gateway:
[Quidway]ip route-static 0.0.0.0 0.0.0.0 119.167.200.89 // Configure the default gateway.
Swap save settings and reset command
<Quidway>save // Save configuration data
<Quidway>reset saved-configuration // Reset change configuration
<Quidway>reboot // Restart the change
Widespread show instructions for the change
Consumer view mode:
<Quidway>show current-configuration // Show the configuration particulars at present operating on the change
<Quidway>show machine // Show the standing of every machine
<Quidway>show interface? // Show every port standing, use ? to examine the choices adopted
<Quidway>show model // Verify the firmware model data of the change
<Quidway>show vlan? // Verify the configuration data of vlan
Restore change manufacturing facility settings
<Quidway>reset saved-configuration // Reset change configuration
II. Fundamental Command Configuration for H3C Switches
H3C change instructions bear resemblance to Huawei change instructions however with refined variations.
Let’s first perceive the configuration instructions and features of H3C. They’re generally used, and most community configurations can’t be with out these instructions.
