Zdravim,
vedeli by ste mi poradit, kde by mohol byt problem?
Mam nasledovnu konfiguraciu: gateway mikrotik x86 (A) ___ router RB850G (B) ___ AP powerbeam AC --- CPE powerbeam AC ___ router RB750G2 Hex (C) ako switch. Na gateway je NAT.
Ked pustim btest z A do C, tak nameram download cca 99 Mbits. Ked pustim btest zo serveru mimo mojej siete do A alebo do B, tak nameram download tiez cca 99 Mbits. Ale ked pustim btest so serveru vonku do C, tak nameram download len max polovicu, do 45 Mbits. Vsetky testy su s 20 spojeniami. Vsetky eth porty na mikrotikoch mam zlinkovane na 100 Mbit FD. Interface queue mam pfifo s queue size 5000 paketov. Kde moze byt problem?
Dakujem za kazdu radu. |

| Diky za odpoved, ale nerobim testy priamo medzi UBNT zariadeniami. Robim testy vzdy z mikrotiku na mikrotik. UBNT je len bridge. |

Parada, diky za radu!
Zapol som najprv flow control medzi A a B, ako aj medzi B a Powerbeamom, ale nezlepsilo sa to. Tak som prepol link medzi A a B zo 100Mbit na 1Gbit a az potom zacala ficat cela trasa az do tych 95 Mbit. Nechapem, v com bol to moze byt, ale aspon to uz ide. |

flow control som zapinal/vypinal na mikrotiku, ak sa robilo napr. mangle alebo nat tak muselo byt flow control zapnute inak nefungovalo...co to vlastne je?
ja som to vzdy vypinal na mikrotiku ked to robilo iba routing. vytazenost cpu vtedy vyrazne klesla |

Ak stroj nestiha spracuvat data poziada protistranu o "spomalenie" . Ide mi o riesenie problemu pri prechode siete 1G na 100m resp bezdrat , kde sa potom deju podivne anomalie , polovicna rychlost u klienta , alebo este nizzsia ... |

| Nenasiel som na nete nic viac o flow-control. Je treba zapnut flow na obidvoch stranach linky alebo staci na jednom stroji ? skusil som iba na jednej strane a zatial testy vysli dobre. Dik za dalsie info. |

Treba zapnut na oboch stranach . Ak ma tuto funkciu nemanazovatelny switch , tak ide flowcontrol nonstop ... Problem je vtom ze zariadenia UBNT nemaju flowcontrol ... okrem af a AC . |
