- 2022-09-02 krowe: sysctl -a | grep <vnet> accross naasc-vs-{3..5} are identical except for the vnet name (e.g. vnet2, vnet4, etc)
- 2022-09-02 krowe: sysctl -a on naasc-vs-3 and naasc-vs-5 have no significant differences.

- 2022-09-07 krowe: iptables -L and iptables -S are identical across naasc-vs-{3..5}
Differences
- 2022-09-02 krowe: sysctl -a | grep <10Gb NIC> accross between naasc-vs-{3..5} are different
3 and naasc-vs-3 is identical to naasc-bs-5 5 are identical except for the name of the NIC (e.g. p5p1, p2p1)..
Differences
- 2022-09-02 krowe: sysctl -a | grep <10Gb NIC> between naasc-vs-3/naasc-vs-5 and are different
- naasc-vs-4 has entries for VLANs 101 and 140 while naasc-vs-3 and naasc-vs-5 have entries for VLANs 192 and 96.
- 2022-09-02 krowe: sysctl -a on naasc-vs-4 and naasc-vs-5 and found many questionable differences
- naasc-vs-4: net.iw_cm.default_backlog = 256
- Is this because the IB modules are loaded?
- naasc-vs-4: net.rdma_ucm.max_backlog = 1024
- Is this because the IB modules are loaded?
- naasc-vs-4: sunrpc.rdma*
- Is this because the IB modules are loaded?
- naasc-vs-4: net.netfilter.nf_log.2 = nfnetlink_log
- nfnetlink is a module for packet mangling. Could this interfear with the docker swarm networking?
- Though the recorded output rate of naasc-vs-5 is about 500 Mb/s while naasc-vs-{3..4} is about 300Kb/s.
- And the recorded input rate of naasc-vs-5 is about 500 Mb/s while naasc-vs{3..4} is about 5 Mb/s.
- This is very strange as it seemed naasc-vs-5 was the limiting factor but the switch ports suggest not. Perhaps this data rate is caused by other VM guests on naasc-vs-5 (helpdesk-prod, naascweb2-prod, cartaweb-prod, natest-arc-3, cobweb2-dev)
- naasc-vs-4: net.iw_cm.default_backlog = 256
- 2022-09-06 krowe: ethtool -k <NIC> for naasc-vs-3 and naasc-vs-4 are very different.
