we have a "MikroTik CRS328-4C-20S-4S+RM 20x SFP + 4xSFP+ switch with 4x combo" switch and are connecting two uplinks to it on the SFP+ ports.
We have 4 10Gb Ethernet ports. I am connecting my laptop to the port combo2 and testing internet connection but i am unable to connect to internet.
I have executed the following commands on the switch
/interface vlan
add interface=sfp-sfpplus1 name=vlan4011_uplink1 vlan-id=4011
add interface=sfp-sfpplus2 name=vlan4022_uplink2 vlan-id=4022
/ip address
add address=192.168.x.y/30 interface=vlan4011_uplink1 network=192.168.x.40
add address=192.168.z.y/30 interface=vlan4022_uplink2 network=192.168.z.40
add address=a.b.c.d/27 interface=combo2
/ip route
add distance=1 dst-address=0.0.0.0/0 gateway=192.168.x.41
add distance=1 dst-address=0.0.0.0/0 gateway=192.168.z.41
any help on how to configure the switch so that internet would be accessible. Thanks.
Re: MicroTik switch unable to access internet
Please provide a network drawing or better description of what is connected to what. Also include your configuration. To export and paste your configuration (and I'm assuming you are using WebFig or Winbox), open a terminal window, and type (without the quotes) "/export hide-sensitive file=any-filename-you-wish". Then open the files section and right click on the filename you created and select download in order to download the file to your computer. It will be a text file with whatever name you saved to with an extension of .rsc. Suggest you then open the .rsc file in your favorite text editor and redact any sensitive information. Then in your message here, click the code display icon in the toolbar above the text entry (the code display icon is the 7th one from the left and looks like a square with a blob in the middle). Then paste the text from the file in between the two code words in brackets.
Re: MicroTik switch unable to access internet
Hello many thanks for your reply.
We have two uplinks from the ISP connected to sfp-sfpplus1 and sfp-sfpplus2 port and below is the file you requested, any help here would be great, Thanks,.
Also, when i try to trace route to 8.8.8.8 i see that we are able to reach 192.168.110.41 which should be one of the uplinks but it does not go beyond that. please see attached screenshot
