dSnake issue – fibre link

[[XAP]BobParticipant]

Anyone used a fibre link for dSnake – getting a connection failure atm…

Any clues on frame size etc?

Note – vlanning through a pair of net gear gs724, but won’t even bounce through one of them at the moment,

Cables confirmed good.

Single, error LED and clicking on channels with phantom

Ok, clicks on all channels.

I’m assuming that there is too much jitter/latency. We’re about to try a different VLAN confit (not trucked over two fibres)

Switching from one media to another indeed may impose too much latency. Not sure if switching between copper and fiber will work without store&forward.

This document refers to ACE but the same recommendations apply to dSNAKE:

Sorted… LLDP was one issue, Aggregation was another.

[[XAP]BobParticipant]

The setup is now as follows…

QU16 connected via ~20m of cat6 (two patch cables and one infrastructure) into a switch.
Vlanned (over a single fibre) to an identical switch, through another set of patch/infrastructure/patch cables to the AR24.

The fibre is about another 15m strung across the road.

The same switches are handling a low latency bidirectional video feed, now tied to the other fibre (it was less fussy about the aggregation).

Without the switches trying to do aggregation or protocol discovery it works – just as it should do.

[[XAP]BobParticipant]

Wow – that was a show and a half – just been to the final night.

The mixer, and dSnake, have been rock solid throughout – would I expect anything less?
