Hi Erman,

I noticed some warnings on 1 host for network interface.

warning:  'át least one slave has a different aggregator id'. How can we know if there is resource contention on the host?

Can you please advise on this?

Thanks,

Roshan

What type of bonding do you use? Looking at the error;  I guess it is LACP in this case.

Note1:
The Aggregator ID value for each interface in an LACP bond should match. If they do not match the switch ports are likely not configured correctly.

Note 2:
The bond may still operate if the Aggregator IDs do not match, but it will only be utilizing a subset of the bonded interfaces.

Check the switch side, the LACP configuration on the switch side may be causing this. -- *Get help from network teams for that. (It is most likely eth1 is connected to a switchport which is a member of a different switch-side ethernet channel than eth0) --> This is from Redhat byteway.

For your OS side, use the following comands to check the bonding conf;

cat /etc/sysconfig/network-scripts/ifcfg-bond0
cat /proc/net/bonding/bond0

Note that, aggregator ids will be displayed with the second command.
