Huawei Switch How To - Configuring VLAN Aggregation

  1. 1. HUAWEI QUIDWAY S5700 HOW-TO CONFIGURING VLAN AGGREGATION www.ipmax.it
  2. 2. GENERAL INFOS AND APPLICATION ENVIRONMENT VLAN7 Department A VLAN5 Department B VLAN10 VLANIF:100.1.1.1/24 VLAN7 VLAN5 Vlan aggregation is a feature that prevents the waste of IP addresses and implements inter-vlan communication in enterprise network environment. Using vlan aggregation, you need to configure IP address only in super-vlan interface, without having to assign IP addresses for each of the sub-vlans: all sub-vlans share the same IP network-segment. In our example we will assume a simple configuration scenario: on an enterprise network, we have different departments belonging to different vlans; employees in different departments need to communicate with ech other. As shown in the picture, the super-vlan will be VLAN 10 and the sub-vlans will be VLAN 5 and VLAN 7. The PC’s IP addresses are in the same IP network segment and are shown in the table. PC1 PC2 PC3 PC4 PC1 IP address: 100.1.1.2/24 PC2 IP address: 100.1.1.3/24 PC3 IP address: 100.1.1.4/24 PC4 IP address: 100.1.1.5/24
  3. 3. ADDING INTERFACES OF THE SWITCH TO SUB-VLANS (1) 1. Set the interface type Enter the configuration view Enter the port view Configure the port type <Huawei> system-view [Huawei] interface gigabitethernet 0/0/1 [Huawei-GigabitEthernet0/0/1] port link-type access [Huawei-GigabitEthernet0/0/1] quit [Huawei] interface gigabitethernet 0/0/2 [Huawei-GigabitEthernet0/0/2] port link-type access [Huawei-GigabitEthernet0/0/2] quit [Huawei] interface gigabitethernet 0/0/3 [Huawei-GigabitEthernet0/0/3] port link-type access [Huawei-GigabitEthernet0/0/3] quit [Huawei] interface gigabitethernet 0/0/4 [Huawei-GigabitEthernet0/0/4] port link-type access [Huawei-GigabitEthernet0/0/4] quit [Huawei] Exit the port view
  4. 4. ADDING INTERFACES OF THE SWITCH TO SUB-VLANS (2) [Huawei] vlan 7 [Huawei-vlan7] port GigabitEthernet 0/0/1 0/0/2 [Huawei-vlan7] quit [Huawei] vlan 5 [Huawei-vlan5] port GigabitEthernet 0/0/3 0/0/4 [Huawei-vlan5] quit [Huawei] 2. Configure vlan 7 and vlan 5 Create and enter the vlan view Add physical ports to vlan Exit the vlan view
  5. 5. ADDING THE SUB-VLANS TO A SUPER- VLAN 3. Configure the super-vlan [Huawei] vlan 10 [Huawei-vlan10] aggregate-vlan [Huawei-vlan10] access-vlan 5 7 [Huawei-vlan10] quit Enter the vlan view Configure the vlan as a super-vlan Add the sub-vlans to the super-vlan Exit the vlan view
  6. 6. CONFIGURING THE IP-ADDRESS FOR THE SUPER-VLAN 4. Configure the vlanif interface for the super-vlan Enter the vlanif view Configure the ip address for the vlanif Exit the vlanif view [Huawei] interface vlanif 10 [Huawei-Vlanif10] ip address 100.1.1.1 24 [Huawei-Vlanif10] quit [Huawei]
  7. 7. CONFIGURING PROXY ARP FOR THE SUPER-VLAN [Huawei] interface vlanif 10 [Huawei-Vlanif10] arp-proxy inter-sub-vlan-proxy enable [Huawei-Vlanif10] quit 5. Configure proxy arp 6. Verify the configuration (vlan 5 is reachable from vlan 7) PC1> ping 100.1.1.4 Ping 100.1.1.4: 32 data bytes, Press Ctrl_C to break From 100.1.1.4: bytes=32 seq=1 ttl=127 time=16 ms From 100.1.1.4: bytes=32 seq=2 ttl=127 time<1 ms From 100.1.1.4: bytes=32 seq=3 ttl=127 time<1 ms From 100.1.1.4: bytes=32 seq=4 ttl=127 time<1 ms From 100.1.1.4: bytes=32 seq=5 ttl=127 time=31 ms --- 100.1.1.4 ping statistics --- 5 packet(s) transmitted 5 packet(s) received 0.00% packet loss round-trip min/avg/max = 0/9/31 ms Enter the vlanif view Enable the proxy arp Exit the vlanif view
