Re: [zeromq-dev] Setting 802.1p VLAN Priority
As with all socket options, it's possible to set it, just nobody has needed it before. Just send a PR. On Mon, 9 Nov 2020 at 19:34, Arnaud Loonstra wrote: > > I guess you didn't get a reply just yet.

Re: [zeromq-dev] Setting 802.1p VLAN Priority
I guess you didn't get a reply just yet. I don't go very deep into the core of libzmq. It seems you already had look yourself. I'm not aware of a socket option you are looking for but we welcome a patch that implements it? Perhaps some of the other maintainers can shred a light on whether this is already possible in libzmq or why not.

[zeromq-dev] Setting 802.1p VLAN Priority
Hi, We use 0MQ for messaging between applications across various VLANs within our system. Recently, we have added a requirement in which we would like to set the 802.1p priority field to something other than 0 for a subset of these connections (most, but not all). There doesn't appear to be any method exposed to directly change the priority of the 0MQ socket (e.g. setsockopt for SOL_SOCKET/SO_PRIORITY which would set the sk_priority field, and then get translated by egress-qos-map on the outbound link) within 0MQ. ZMQ_TOS is close, but by my understanding, that relies on (for us on top of Linux at least) a pre-determined mapping in the kernel and calculations based on DSCP values. Also, it doesn't appear to offer a mapping to the value of 3 which we're trying to set, even if we tried that route. As a temporary solution, we created a quick patch on top of ZMQ to allow directly setting the SO_PRIORITY via a new option in zmq::options_t::setsockopt, but it would be easier, of course, if we didn't have to patch 0MQ to accompish this end. Is there another method to set sk_priority directly via already existing 0MQ methods that I'm unaware of?
