Hello,
Need some help in configuring flow table eviction group.
I tried to configure the eviction group, but i am seeing some warn/errors
and didn't come across any sample commands in web.
1. Can you please share some sample commands for passing NXM_OF_IN_PORT[]
as an argument to flow_table, overflow_policy, "groups"
2. As overflow_policy=evict, by default removes the flow which is going to
expire at the earliest.
i want to configure the group in such a way, the group with the highest
number of common VLAN entries should evict first, i suppose i need to use
NXM_OF_VLAN_TCI
3. Is it possible to do flow table eviction based on the output port
instead of NXM_OF_IN_PORT ? there is no NXM_OF_OUT_PORT, so is that NO ?
The reason i am asking this is, I use "Learn" action to dynamically
create MAC learn flows; so there will be more entries with common output
port, than source VLAN or MAC, so doing eviction based on output port is
preferred ?
This is what i tried in ovs-2.5.0, i am getting following warning.
ovs-vsctl add-br kapil
ovs-vsctl -- --id=@ft create Flow_Table flow_limit=5
overflow_policy=evict group=NXM_OF_IN_PORT -- set Bridge kapil
flow_tables=0=@ft

Kapil.
