Example:

  1. Configure IP address on management port "eth0"
  2. Configure IP address on front port (aka physical interface)
  3. Configure IP address on port channel interface
  4. Configure IP address on loopback interface.

Reference model:

  • Switch model name:

- AS7726-32X

- AS7326-56X

- AS7816-64X

- AS5835-54X(T)

- AS4630-54PE

- AS9716-32D

- AS8000(Minipack)

- Wedge100BF-32X

  • Edgecore SONiC version: 

- Edgecore-SONiC_20201123_130028_ec202006_74

- Edgecore-SONiC_20201229_070315_ec202006_101

- Edgecore-SONiC_20201229_070315_ec202006_bfn_65(Wedge100BF-32X)

Default setting:

  1. DHCP address on management port"eth0"
  2. All of management port on Edgecore model will be "eth0"

 

Example 1: Configure IP address on management port "eth0"

Procedure :

Steps 1. Configure IP address on management port "eth0" 

admin@sonic:~$ sudo config interface ip add eth0 188.188.97.16/16 188.188.1.1
admin@sonic:~$ sudo config interface ip add eth0 2001::8/64 2001::1

Steps 2. Check IP address 

admin@sonic:~$ show ip interfaces

admin@sonic:~$ show management_interface address
Management IP address = 188.188.97.16/16
Management Network Default Gateway = 188.188.1.1
Management IP address = 2001::8/64
Management Network Default Gateway = 2001::1

Caution: "BGP Neighbor" and "Neighbor IP" won't support on 202006 branch.

Steps 3. Save the setting to config_db.json

admin@sonic:~$ sudo config save -y

Steps 4. Check IP address setting on config_db.json

admin@sonic:/etc/sonic$ sudo vi config_db.json 
{ 
   ...omitted 
   "MGMT_INTERFACE": {
       "eth0|188.188.97.16/16": {
           "gwaddr": "188.188.1.1"
        },
        "eth0|2001::8/64": {
            "gwaddr": "2001::1"
        }
     }, 
     ...omitted
}
