We have a small problem with promiscuous mode check. There is number of virtual machines running on KVM host. One moment instances couldn't get IP addresses from remote DHCP-server. The reason, I think, is promisc mode turned off on the physical host interface.
The output below is from the problem host. Non-zero promiscuity and flags (0x100) show that promisc is on.
Code: Select all
[root@comp-1 ~]# ip -d link show dev eno2
5: eno2: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq master team1 state UP mode DEFAULT qlen 1000
link/ether d8:c4:97:09:86:b4 brd ff:ff:ff:ff:ff:ff promiscuity 2
team_slave addrgenmode eui64
[root@comp-1 ~]# cat /sys/class/net/eno2/flags
0x1103
But the output above doesn't have PROMISC keyword as in output from the other host with no such problems:
Code: Select all
[root@comp2 ~]# ip -d link show dev eno2
3: eno2: <BROADCAST,MULTICAST,PROMISC,UP,LOWER_UP> mtu 1500 qdisc mq master team1 state UP mode DEFAULT qlen 1000
link/ether d8:c4:97:09:8b:3d brd ff:ff:ff:ff:ff:ff promiscuity 1
team_slave addrgenmode eui64
[root@comp2 ~]# cat /sys/class/net/eno2/flags
0x1103
Thanks.
