/sbin/ip netns exec swns ifconfig
/sbin/ip netns exec swns ip route

How to sniff traffic:

/sbin/ip netns exec swns /usr/sbin/tcpdump -nvli <eth_name>
/sbin/ip netns exec swns /usr/sbin/tcpdump -vvv -i

How to check ports inside the bridge:

/opt/openvswitch/bin/ovs-vsctl list port bridge_normal

How to check mac aging:

/opt/openvswitch/bin/ovs-appctl -t /run/openvswitch-sim/ovs-vswitchd-sim..ctl fdb/show bridge_normal
/opt/openvswitch/bin/ovs-ofctl dump-ports bridge_normal
/opt/openvswitch/bin/ovs-ofctl show bridge_normal

How to check openflow flows:

/opt/openvswitch/bin/ovs-appctl -t /run/openvswitch-sim/ovs-vswitchd-sim.<>.ctl dpif/dump-flows bridge_normal

How to check information inside specific table:

How to change logging levels for OpenSwitch daemons:

1. Go to ops-build/yocto directory
2. Find the required .service file, for example for zebra it is ops-zebra.service
3. Modify ExecStart parameters: vFILE:DBG will provide maximum level of logging into separate log file, specified by parameter --log-file=path-to-log-file
4. Rebuild the image
