I look at
root#ovs-vsctl get interface port-to-routerA statistics
{collisions=0, rx_bytes=2845224091, rx_crc_err=0, *rx_dropped=0*,
rx_errors=0, rx_frame_err=0, rx_over_err=0, rx_packets=2469921,
tx_bytes=1390987, *tx_dropped=0*, tx_errors=0, tx_packets=11200}
root#
and the ifconfig statistics.
root# ovs-dpctl show
system@ovs-system:
lookups: hit:50254324 missed:15221 *lost:4424*
flows: 0
port 0: ovs-system (internal)
port 1: br0 (internal)
port 2: port-to-routerA (gre: df_default=false, ttl=0)
root#
I just see *4424 *packets getting lost. What are these packets? Any idea
when would we lose them?
Thanks, Abhishek
