• The router must be configured to work with
VLANs for most operations.
• Ensure the trunk ports are tagged correctly.
• Contact CIS for assistance.
• CIS recommends DAC SFP cables such as the
CIS-SFP-001 and 003, though other SFP
modules are compatible.
• Ensure the SFP cables are inserted completely.
There should be a slight click as they are
inserted. They will slide in most of the way
when upside down but will not fit completely.
• Check the interface status. Click Interfaces,
then the Ethernet tab. Click on the SFP port in
question. Determine if it is passing traffic.
Consider disabling auto negotiation and
setting the speed and duplex manually.
• Some features are unavailable before
firmware version 6.48. Contact CIS to perform
a firmware upgrade your equipment.
