I have a network and I want to list the ports on the ovs switch

[root@worker-4 ~]# ovs-vsctl  --columns=name,mac_in_use,mtu find interface external_ids:"k8s.ovn.org/network"="vlan-1924"
name                : "81a5ebcb6fa45_3"
mac_in_use          : "be:a0:20:9b:b1:de"
mtu                 : 1400

name                : "040cd3693b52c_3"
mac_in_use          : "c2:93:f7:05:0a:6e"

If you are setting up OpenShift Virt you oftent want to confirm the customer is actually sending VLAN tags to the node before troubleshooting deeper. Here is a tcpdump that can be used.

Log into the node and run toolbox to gain access to tcpdump.

prove 802.1q trunking is coming from the switch

[root@rhel-node-1 ~]# tcpdump -enni eth1 ether proto 0x8100 # 802.1q
dropped privs to tcpdump
tcpdump: verbose output suppressed, use -v[v]... for full protocol decode
