 Goal: To achieve link redundancy and bandwidth overlay through Eth-Trunk, and at the same time, PC1 and PC2 can communicate across switches. 2. Detailed configuration steps 1. Switch S1 configuration <Huawei> system-view [Huawei] sysname S1 # Step 1: Create Eth-Trunk 1 and join the physical interface [S1] interface Eth-Trunk 1 [S1-Eth-Trunk1] port link-type trunk # Configure the link type as Trunk [S1-Eth-Trunk1] port trunk allow-pass vlan all # Allow all VLANs to pass [S1-Eth-Trunk1] quit [S1] interface GigabitEthernet0/0/1 [S1-GigabitEthernet0/0/1] eth-trunk 1 # Add the interface to Eth-Trunk 1 [S1-GigabitEthernet0/0/1] quit [S1] interface GigabitEthernet0/0/2 [S1-GigabitEthernet0/0/2] eth-trunk 1 [S1-GigabitEthernet0/0/2] quit [S1] interface GigabitEthernet0/0/5 [S1-GigabitEthernet0/0/5] eth-trunk 1 [S1-GigabitEthernet0/0/5] quit # Step 2: Configure the access port of PC1 (Access mode) [S1] vlan batch 10 # Create VLAN 10 [S1] interface Ethernet0/0/1 [S1-Ethernet0/0/1] port link-type access [S1-Ethernet0/0/1] port default vlan 10 [S1-Ethernet0/0/1] quit # Step 3: Configure the VLANIF interface (to achieve cross-switch interoperability) [S1] interface Vlanif 10 [S1-Vlanif10] ip address 10.0.1.254 24 # Configure the gateway of VLAN 10 [S1-Vlanif10] quit ---------------------------------------------------- 2. Switch S2 configuration <Huawei> system-view [Huawei] sysname S2 # Step 1: Create Eth-Trunk 1 and join the physical interface [S2] interface Eth-Trunk 1 [S2-Eth-Trunk1] port link-type trunk [S2-Eth-Trunk1] port trunk allow-pass vlan all [S2-Eth-Trunk1] quit [S2] interface GigabitEthernet0/0/1 [S2-GigabitEthernet0/0/1] eth-trunk 1 [S2-GigabitEthernet0/0/1] quit [S2] interface GigabitEthernet0/0/2 [S2-GigabitEthernet0/0/2] eth-trunk 1 [S2-GigabitEthernet0/0/2] quit [S2] interface GigabitEthernet0/0/5 [S2-GigabitEthernet0/0/5] eth-trunk 1 [S2-GigabitEthernet0/0/5] quit # Step 2: Configure the access port of PC2 (Access mode) [S2] vlan batch 10 [S2] interface Ethernet0/0/1 [S2-Ethernet0/0/1] port link-type access [S2-Ethernet0/0/1] port default vlan 10 [S2-Ethernet0/0/1] quit # Step 3: Configure the VLANIF interface (in the same network segment as S1 to achieve intercommunication) [S2] interface Vlanif 10 [S2-Vlanif10] ip address 10.0.1.253 24 # Configure the same network segment IP (optional, if only PC communication is required, the gateway can only be configured with S1) [S2-Vlanif10] quit 3. PC configuration PC1: IP 10.0.1.1, subnet mask 255.255.255.0, gateway 10.0.1.254 (Vlanif10 of S1). PC2: IP 10.0.1.2, subnet mask 255.255.255.0, gateway 10.0.1.254 (Vlanif10 of S1). 4. Verify configuration Eth-Trunk status verification: Run display eth-trunk 1 on S1 or S2 to confirm that the physical interfaces have been added and the status is Up. PC interoperability verification: Execute ping 10.0.1.2 on PC1 and PC2 should be successfully connected. Through the above configuration, the three links between S1 and S2 have been aggregated into Eth-Trunk, achieving link redundancy and bandwidth overlay. At the same time, PC1 and PC2 can communicate across switches. |
