Im trying to switch all ports on RB493G, but without success, got this message "master-port must be in same switch group" when trying to set ether6 use master port of ether2, allright at least i need switch ports 2-8, but not two switches of four ports. Found that ether1 is not possible to use, to act like 9 port switch, like its written here http://forum.mikrotik.com/t/how-to-switch-all-port-on-rb493/40836/1 How to make 8 port switch with RB493G without bridging them?
rb493g has 2 switch chips, so I guess you have to divide them into 2 groups.
That`s right, it has two switch chips, but how to make rb493g act like a simple 8 port switch, one group of 8 switched ports, without bridging?
I doubt you can do that.have you sent email to support?
It is not possible to switch 8 ports in single switch group. However you can make ether1+ether6-ether9 and ether2-ether5 switch groups and then bridge the master-ports.
thats interesting. i was considering purchasing this rb for this purpose.
now if i bridge ALL ports will it make all ports a switch?
can you please explain this part a bit more?
so ether1 and ether6 are the master ports
and 7-9 are slaves to 1
2-5 are slaves to 6?
very confused.
Ether1,ether6-ether9 ports are connected to switch-chip1, ether2-ether5 are connected to switch-chip2. Any of the port from switch-chip1 or switch-chip2 can be configured as master-port by assigning assign other port from the same switch as its slave port. There can only be one master-port per each switch-chip1 and switch-chip2.
so how can i make all those into ONE switch then?
i made ether1 a master port and slave everything else to it?
please show example.
No, ether1,ether6-ether9 ports are connected to switch-chip1, so only ether6-ether9 can be slave ports for ether1. Any switch-chip1 ↔ switch-chip2 traffic needs to go through the CPU.
by the way the blink button doesnt do anything . … i assume a cable has to be plugged in for it to do its function?
back to the subject;
for ether 1 i slaved 6,7,8,9
for ether 2 i slaved 3,4,5
then i bridged ether 1 and ether2.
this should work… Right? now i have one switch?
second question; i noticed that when a port is slaved it doesnt show traffic passing through it. only the master port shows the traffic.
does this still mean that all ports are running at gigabit speeds individually or are they combined?
It will work as one switch, but actually its two switches bridged together: switch ↔ bridge ↔ switch.
i did a bandwidth test and the CPU rose to the roof (100%). good news is i was getting 400mb (50MB). not the best but still a useable number. certainty does defeat the name “Gigabit port”. a Gigabit is 128000MB so i am 78MB off. thats 624mb.
For full wire speed, use a crossover cable and link the two master ports of the two switch-chips together instead of using the CPU bridge. This eliminates the CPU based bridge which is causing high CPU activity. But at the cost of two GigE ports.
Your decision, high cpu, or fewer GigE ports.
