Re: CRS354-48P-4S+2Q+ traffic problem on ports 1 to 8

Have you guys tried 7.13.1? Those switch changes should fix the CRS354 issues described in the topic Looking for "Does" not interested in "should". Everybody looked something else already, even used equipment from ebay (other vendors equipment "works" as it should be).

Another option is buying Linux VM from VPS hosting ( each has its own public ipv4, virtual machine ) - you making SNAT/DNAT to your Router.

Hi!

Not long range, ~ 4km link Netmetal-5 both 450 Mbps@5Ghz at peak,
planning to replace to 60Ghz Radio (no Mikrotik), but We keep CCR for routing.

The 5Ghz range is too noisy, usable spectrum is small, time to move to 60Ghz.
