Generally, the devices either be restricted to allow specific SFP models (even for the same vendor) or allow any SFP from any vendor. Even for the same vendor yo could some devices are restricted and others are unrestricted. This is because they sometimes aquire devices from another vendor under their logo.

thanks for your reply @EEHC, did this can be the problem because the port from the switch core is down/down

where can i find the list of supported SFP by FortiSwitch please ? or there are any config should be added to the port in side of the FS and Cisco 3750 ?

 

thanks in advance.

    thank you @EEHC 

     

    the link between cisco switch and fortiswitch become UP/UP now when configured the speed in both side but still no traffic

    i didn't find exactly the SFP supported, i want to verify that " SFP cisco glc-sx-mmd 1000base-sx " is supported or no ? how i can check this please ?

    thanks in advance

    You have two methods. Either try to install SFP and check if the device detects or not. You know that physically if the interface is not shut that a leight is sent out and the port of the connected device is up. If a device accepts SFP from another vendor, you expected that it will accept from others. The problem is when you make an order. In this case, you have to ask if anyone installed foreign  SFPP in this device or search on the internet.

    thanks @EEHC the SFP is supported by FS and the problem is solved by the reconfiguration of speed in both side (FS and cisco switch) and config the write the vlan access ID in native and allowed and untagged vlan. also in the trunk port should write all the vlan ID in allowed VLAN.

     

    thank you
