Tagged VLAN configurations with a cmp-hash setting for the VLAN, might result in performance issues.
Throughput is lower than expected. Packets are not being hashed using the hash set in config. (This can be verified by looking at 'tmm/flow_redir_stat'.)
This occurs when the following conditions are met: 1. Use of tagged VLANs in the configuration. 2. Change cmp-hash of the tagged VLAN.
Use untagged VLANs and hypervisor side tagging.
You can now use tagged VLAN configurations along with a cmp-hash setting for the VLAN, without compromising performance.
