Currently tested on the April 2021 release.
All configuration change done with
sudo config need at some point a
sudo config save to make them permanent (eg. device reboot)
sudo config hostname dell-spine1
SONiC supports having the management interface in a dedicated VRF, so the default management route (to mr1) doesn't risk impacting production traffic.
sudo config vrf add mgmt
sudo config interface ip add eth0 10.x.x.x/16 10.x.0.1
show management_interface address
Have SNMP listen on its mgmt IP
sudo config snmpagentaddress add 10.x.x.x -v mgmt -p 161
In the tested release,
sudo config snmp is not a valid configuration keyword.
Workaround to set the SNMP community:
sudo vim /etc/sonic/snmp.yml
sudo systemctl restart snmp
sudo config ntp add <server IP>
- It is not possible to configure a DNS resolver, all configuration needs to be done using IPs
- It is not possible to change the syslog facility
cgexec -g l3mdev:mgmtis supposed to run commands from the mgmt VRF, but fails with "cgroup change of group failed"
