Port shut down problems on SM9800 when using SonicWall 1GB modules (01-SSC-9791)
On the SonicWall SM9800 Rev A and SM9800 Rev C using SonicWall 1GB modules (01-SSC-9791)
There is a known issue with SonicWall 01-SSC-9791 1GB SFP for Administrative Enable/Disable from UI. When the SM9800 uses SonicWall 1GB modules (01-SSC-9791), the link negotiation on SM9800 works fine and comes up when you physically plug into the port, but does not honor any port shut down either initiated from the SM9800 port or by the peering switch port.
Use SonicWall 1GB modules (01-SSC-9789) or 1G SFP on SonicWall SM9800
Do not use SonicWall modules (01-SSC-9791) on SonicWall SM9800
