Packet drops are observed on the br-int (integration bridge) interface of the hypervisors
- Platform9 Managed OpenStack - v4.0 and Higher
- Open vSwitch
The br-int interface does not have networking configuration and its status is DOWN. Any broadcast/multicast packet hitting this interface will get dropped causing the counter to increment.
$ ip -s link show br-int
30: br-int: <BROADCAST,MULTICAST> mtu 1450 qdisc noop state DOWN mode DEFAULT group default qlen 1
link/ether ae:5c:09:cb:a5:43 brd ff:ff:ff:ff:ff:ff
RX: bytes packets errors dropped overrun mcast
0 0 0 4732073 0 0
TX: bytes packets errors dropped carrier collsns
0 0 28635 0 0 0
An increase in the number of drop packets should not cause any networking issue and can be safely ignored.
