RUIJIE CLI Create VLAN, Create DHCP, Create Gateway, Create Encapsulation, Create Trunk and Create Access

 This guide provides the CLI commands for Ruijie RGOS switches and gateways to create VLANs, DHCP servers, Layer 3 gateways (SVI), encapsulation (802.1Q), and configure trunk/access ports based on standard Ruijie configuration procedures
. 
1. Create VLANs
Create VLAN 10 and VLAN 20. 
cmnd

Ruijie> enable
Ruijie# configure terminal
Ruijie(config)# vlan 10
Ruijie(config-vlan)# name DATA
Ruijie(config-vlan)# exit
Ruijie(config)# vlan 20
Ruijie(config-vlan)# name VOICE
Ruijie(config-vlan)# exit

2. Create Gateway (SVI - Switched Virtual Interface) 
Create the IP address for the VLAN, which serves as the default gateway for client devices. 
cmnd

Ruijie(config)# interface vlan 10
Ruijie(config-if-VLAN 10)# ip address 192.168.10.1 255.255.255.0
Ruijie(config-if-VLAN 10)# no shutdown
Ruijie(config-if-VLAN 10)# exit

3. Create DHCP Server 
Configure the switch to act as a DHCP server for the VLAN. 
cmnd

Ruijie(config)# service dhcp
Ruijie(config)# ip dhcp pool VLAN10_POOL
Ruijie(dhcp-config)# network 192.168.10.0 255.255.255.0
Ruijie(dhcp-config)# default-router 192.168.10.1
Ruijie(dhcp-config)# dns-server 8.8.8.8
Ruijie(dhcp-config)# exit

4. Create Access Port 
Assign a physical port to a specific VLAN. 
cmnd

Ruijie(config)# interface gigabitEthernet 0/1
Ruijie(config-if-GigabitEthernet 0/1)# switchport mode access
Ruijie(config-if-GigabitEthernet 0/1)# switchport access vlan 10
Ruijie(config-if-GigabitEthernet 0/1)# exit

5. Create Trunk Port & Encapsulation 
Configure an uplink port to carry multiple VLANs. Ruijie uses IEEE 802.1Q for encapsulation, which is typically standard. 
cmnd

Ruijie(config)# interface gigabitEthernet 0/24
Ruijie(config-if-GigabitEthernet 0/24)# switchport mode trunk
! Permit only specific VLANs (optional but recommended)
Ruijie(config-if-GigabitEthernet 0/24)# switchport trunk allowed vlan add 10,20
Ruijie(config-if-GigabitEthernet 0/24)# exit

6. Save Configuration
cmnd

Ruijie(config)# exit
Ruijie# write

Key Considerations

    Encapsulation: While Cisco switches often require switchport trunk encapsulation dot1q before switching to trunk mode, Ruijie switches typically default to 802.1Q encapsulation.
    VLAN 1: Do not delete VLAN 1; it is the default management VLAN.
    Gateway Requirement: Ensure you create SVI interfaces on the Core Switch or EG Gateway for traffic to route between VLANs.
