Hi,
Could someone tell me how to shorten recovery time after a bonded port failed?
When two physical ports named eth0 and eth1 are bonded to a port, for example
named bond_port_eth,
eth0 and eth1 will be removed from table port of the database, and
bond_port_eth is inserted instead.
But there is no interface named bond_port_eth in table interface of the
database. So no ofport is available for
port bond_port_eth, and we can not specify ofport of bond_port_eth in flow, and
the ofports of eth0 and eth1 are used instead.
Based on the reality, we use the ofport of eth0 or eth1 in our learned flows,
which leads to long recovery time.
Here is the settings of the bond port.
_uuid : 00f7a5cc-3a4b-42cb-a265-c8fcbcce78fb
bond_active_slave : "74:a4:b5:00:4b:89"
bond_downdelay : 0
bond_fake_iface : false
bond_mode : balance-tcp
bond_updelay : 0
external_ids : {}
fake_bridge : false
interfaces : [418be768-eb9e-4522-8353-0ac693321294,
ef828455-5e15-40d5-91c4-b511fd7a9417]
lacp : active
mac : []
name : "bond-port-eth"
other_config : {lacp-time=fast}
qos : []
statistics : {}
status : {}
tag : []
trunks : []
vlan_mode : []
There is a flow with a action:
actions=learn(table=1,idle_timeout=300,priority=33000,cookie=0x4,in_port=57,NXM_OF_ETH_DST[]=NXM_OF_ETH_SRC[],output:NXM_OF_IN_PORT[])
If all packets from a vm named VM1 are transmitted on eth0, when eth0 failed,
the lacp can detect the failure quickly,
while the learned flows need to be updated after receiving a new arp packet
from the physical port eth1.
