Example:

  • Configure IP address on management port "eth0"
  • Configure IP address on front port (aka physical interface)
  • Configure IP address on port channel interface
  • Configure IP address on loopback interface.

Reference model:

  • Switch model name:All
  • Edgecore SONiC version: SONiC.Edgecore-SONiC_20201123_130028_ec202006_74

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

eth0                  188.188.97.16/16    up/up        N/A         N/A 
lo                    127.0.0.1/8         up/up        N/A         N/A 

admin@sonic:~$  show ipv6 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
}
