when connecting to the SFP+ port of the switch with the rb5009 sfp+, the connection failed, and then the router was sent to the Netgear manufacturer for testing.
The response from the manufacturer was that the problem occurred when the MS510TXM continued to send packets to the MitroTik device, but the MitroTik device stopped sending data to the MS510TXM. The results of this test confirmed that it was caused by the MitroTik’s 10G SFP+ optical port supporting the EEE (Energy-Efficient Ethernet) feature, while the MS510TXM’s 10G SFP+ optical port does not support EEE (the MS510TXM’s 10G electrical port does support EEE)
Can rb5009 turn off EEE for testing sfp+ available
This affects all switch does not support EEE on their sfp+. I have Zyxel xs1930-12hp. It does not support EEE on its two SFP+ uplink ports. I experience the same issue. Having an option to disable EEE at mikrotik side would be a solution.
According to the 802.3az standard, EEE shall only be enabled if agreed on both ends during link auto negotiation, using a special “next page” for EEE.
Some devices allow to force-enable EEE if auto negotiation is disabled, but this is not conforming to the 802.3az spec.
So either the RB5009 activates EEE although auto-neg off or the link partner does not advertise it, or the link partner advertises it but does not support it. The first would be a bug on RB5009, the latter a bug on the link partner.
But still it would be a good thing to be able to enable/disable EEE on RB5009. Some devices with broken EEE support have link reliability issues when enabled.
Would be really nice to have a way to disable EEE in hardware, it seems to me very similar to what is happening with the X520 adapters, though I struggle to believe this is doing the ‘wrong’ thing during 802.3az negociation…
I checked the beta33 release notes but had not checked beta34. I’ll check it out thanks.
