Instead of well-known manufacturers of switches with sfp optical transmitters were purchased crs125-24g-1s-rm
The scheme is :
Members office 1 -crs125-24g-1s-rm + S-53LC20D - Optics - S-35LC20D-crs125-24g - ( 3pc RB951Ui-2HnD, two 48- port switch 3Com with 1G 2 ports) - users office 2
Of course, I knew that I would not have to L2 loop detection and so… but did not expect that they will fall off every second link ports on both CRS routers . CPU loaded onto 20-25 % even at minimum load . I had monitor for loops , and ports disable while testing .
I must say that they are now configured in the simple mode . SFP port is selected master - the rest are in slave mode. Bridge is not used , so as not to stretch in percent at gigabit ports. Firmware 6.7 .
Who can tell where to dig?
