Configuring Interfaces

Procedure

1. Add physical interfaces to Eth-Trunks.

   The following uses the configuration of Core_SPE1 as an example. The configurations of other devices are similar to the configuration of Core_SPE1, and are not mentioned here.

   #
   interface XGigabitEthernet1/0/0
    eth-trunk 5
   #
   interface XGigabitEthernet1/0/1
    eth-trunk 5
   #
   interface XGigabitEthernet1/0/2
    eth-trunk 5
   #
   interface XGigabitEthernet1/0/3
    eth-trunk 5
   #
   interface XGigabitEthernet5/0/4
    eth-trunk 4
   #
   interface XGigabitEthernet5/0/5
    eth-trunk 4
   #
   interface XGigabitEthernet5/0/6
    eth-trunk 4
   #
   interface XGigabitEthernet5/0/7
    eth-trunk 4
   #
   interface XGigabitEthernet6/0/0
    eth-trunk 17
   #
   interface XGigabitEthernet6/0/1
    eth-trunk 17
   #
   interface XGigabitEthernet6/0/2
    eth-trunk 17
   #
   interface XGigabitEthernet6/0/3
    eth-trunk 17
   #

2. Configure descriptions and IP addresses for interfaces.

   The following uses the configuration of Core_SPE1 as an example. The configurations of other devices are similar to the configuration of Core_SPE1, and are not mentioned here.

   #
   interface Eth-Trunk4
    undo portswitch
    description Core_SPE1 to Core_SPE2
    ip address 172.17.4.8 255.255.255.254
   #
   interface Eth-Trunk5
    undo portswitch
    description Core_SPE1 to Core_SPE3
    ip address 172.17.4.2 255.255.255.254
   #
   interface Eth-Trunk17
    undo portswitch
    description Core_SPE1 to Site1_UPE1
    ip address 172.17.4.10 255.255.255.254
   #
   interface XGigabitEthernet6/0/4
    undo portswitch
    description Core_SPE1 to Site3_UPE6
    ip address 172.17.10.2 255.255.255.254
   #
   interface LoopBack1
    description ** GRT Management Loopback **
    ip address 172.16.0.5 255.255.255.255
   #

3. Configure Eth-Trunks to function as 40GE interfaces.

   Run the least active-linknumber 4 command on Eth-Trunks of all S9700 switches to configure the Eth-Trunks to function as 40GE interfaces. If a member interface of an Eth-Trunk goes Down, the Eth-Trunk goes Down. The following uses the configuration of Core_SPE1 as an example. The configurations of other devices are similar to the configuration of Core_SPE1, and are not mentioned here.

   #
   interface Eth-Trunk4
    least active-linknumber 4
   #
   interface Eth-Trunk5
    least active-linknumber 4
   #
   interface Eth-Trunk17
    least active-linknumber 4
   #

4. Create Eth-Trunk load balancing profiles and apply the profiles to Eth-Trunks.

   Configure load balancing based on the source and destination port numbers. The following uses the configuration of Core_SPE1 as an example. The configurations of other devices are similar to the configuration of Core_SPE1, and are not mentioned here.

   #
   load-balance-profile CUSTOM
    ipv6 field l4-sport l4-dport
    ipv4 field l4-sport l4-dport
   #
   interface Eth-Trunk4
    load-balance enhanced profile CUSTOM
   #
   interface Eth-Trunk5
    load-balance enhanced profile CUSTOM
   #
   interface Eth-Trunk17
    load-balance enhanced profile CUSTOM
   #

5. Disable STP globally.

   All devices on the entire network are connected through Layer 3 interfaces, and Layer 2 loop prevention protocols are not required. Therefore, disable STP globally. The following uses the configuration of Core_SPE1 as an example. The configurations of other devices are similar to the configuration of Core_SPE1, and are not mentioned here.

   #
   stp disable
