[Edgecore SONiC] Management and front port IPv4/IPv6 Address Follow
- 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.
- Frequently Asked Question
Tested model & firmware version:
- Switch model name:
DCS203 (AS7326-56X)
- Edgecore SONiC version:
202006.4
202012.0 ~ 202012.4
202111.0
Restriction:
- Default setting:
- DHCP address on management port"eth0"
- All of management port on Edgecore model will be "eth0"
- [202012] Known issue:
- [SONIC-3300] Set the IP and default gateway using the command "config interface ip add eth0 <ip / mask> <gw>", the default route is not displayed with "ip route show" or "show ip route".
- This is a display issue and the default route is still valid.
- (Workaround) Use "ip route show table default" instead of "show ip route". Here is an example shown below,
-
admin@sonic:~$ sudo config interface ip add eth0 192.168.1.10/24 192.168.1.254
admin@sonic:~$ ip route
192.168.1.0/24 dev eth0 proto kernel scope link src 192.168.1.10
240.127.1.0/24 dev docker0 proto kernel scope link src 240.127.1.1 linkdown
admin@sonic:~$ show ip route
Codes: K - kernel route, C - connected, S - static, R - RIP,
O - OSPF, I - IS-IS, B - BGP, E - EIGRP, N - NHRP,
T - Table, v - VNC, V - VNC-Direct, A - Babel, F - PBR,
f - OpenFabric,
> - selected route, * - FIB route, q - queued, r - rejected, b - backup
t - trapped, o - offload failure
C>* 192.168.1.0/24 is directly connected, eth0, 00:00:11
admin@sonic:~$ ip route show table default
default via 192.168.1.254 dev eth0 metric 201
192.168.1.0/24 dev eth0 scope link
- [SONIC-3300] Set the IP and default gateway using the command "config interface ip add eth0 <ip / mask> <gw>", the default route is not displayed with "ip route show" or "show ip route".
Configure IP address on management port "eth0"

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
}

Frequently Asked Question
Why cannot set the management IP after typing the correct command?
Tested model & firmware version:
- Switch model name:
DCS203 (AS7326-56X) - Edgecore SONiC version:
202111.0
Problem description:
admin@sonic:~$ sudo config interface ip add eth0 188.188.36.123/16
admin@sonic:~$ show ip int
Interface Master IPv4 address/mask Admin/Oper BGP Neighbor Neighbor IP
----------- -------- ------------------- ------------ -------------- -------------
docker0 240.127.1.1/24 up/down N/A N/A
lo 127.0.0.1/16 up/up N/A N/A
This problem will happen on the 202111 version.
Solution:
Step 1: Make sure there's a "config_db.json" at /etc/sonic.
admin@sonic:~$ ls /etc/sonic/
asic_config_checksum fast-reboot_order sonic-environment
config_db.json frr sonic_version.yml
constants.yml generated_services.conf swss_dependent
copp_cfg.json init_cfg.json updategraph.conf
core_analyzer.rc.json remote_ctr.config.json warm-reboot_order
dhcp_relay_reconcile snmp.yml
Note:
There's no "config_db.json" after installing the SONiC from ONIE, so it needs to generate a new one.
Step 2: Generate a "config_db.json", please follow this article.
Step 3: After generating the default "config_db.json", then it could set the management IP.
