Re: Omni-Path vs. Mellanox
Hi Serge, Here are the answers:1. it is for copper cables up to 2m in length and fiber optics up to 30m in length. Beyond that we have of course a superset of more capabilities (FEC and LLR) that being...

Even with the bandwidth setting for TC 0 reduced to 10, TC 1 increased to 30, and TC 3 increased to 60 to accommodate priorities 6 and 7 that were not explicitly assigned there, it turns out to be...

Hi Gerald,See this The mlnx_qos command has the following parameter options: -p : maps priority (UP) to TC, in this example we can map priority i to TCi (for example, priority 1 to TC 1, priority 3 to...

The key seems to be the phrase that comes after the mlnx_qos instructions: “On the switch side…” I don’t think I need either vconfig or mlnx_qos, because I’m using libpcap and creating my own VLAN tags...

Than the best thing for you to have two types of flows, each one with different L2 priority. and configure the switch with SP to prefer one of the priority on the other.map each priority to different...

Hi Carlo, " Bridged interfaces: vlan 1(D), pkey 0x7fff" means that there is no active ports that are members of vlan1.This is because vlan 1 is not on port-channel 2: interface port-channel 2...

OK, interesting. I added vlan 1 to port-channel 2. Port-channel 2 is the Ethernet link to a pair of Arista switches which are supplying vlan 236 as a trunk to the Mellanox switch (BTW it is a 6036G)....

Carlo, I dont want to confuse you more.But the concept of the proxy arp is that you map a pkey ( ib partition ) to a vlan. Anyhow i would recommend reading the gateway section in the mlnx-os UM.

I’ve done this, assigning 5 to TC2 and 4 to TC1, with 0-3 on TC0. Since priority 4 still permits significant interruption of priority 5 traffic, I want to try lowering it to priority 3, while moving 3...

Thanks for your patience. I now seem to have an optimal configuration using the default TC assignments (based on a check of the running-config) of 5 in TC2 for small frames and 2 in TC1 for jumbo...
