GS1900 Static MAC not working as expected

networkblizzard

I just installed a GS1900 24 port switch. Very pleased so far.

I want to have a certain machine always assigned a certain VLAN. I tried using the Static MAC function, but it does not appear to be working.

Config → MAC Table → Static MAC → Add

I added the Mac Address of the client, I set the VLAN I want the client to be on, and I set the port to the port the client will connect to.

Each time I restart the client, it connects to the DHCP server via the PVID VLAN, not the VLAN I set in the static MAC.

Under Monitor → MAC Table I see two entries of my MAC address. One says the correct VLAN and type is Static Unicast. The other entry is the PVID VLAN and the type is Dynamic.

Any ideas? Is there any way I can associate an MAC address with a specific VLAN each time it connects?

Hi @networkblizzard,

» This needs the device to support MAC-based VLAN function which GS1900 does not support it.

Please consider GS1915 or the above model which can fulfill your requirement.

That answers my question, thank you.

Just curious, what is the function of Configuration → MAC Table → Static Mac? What does that do?

Thanks!

Hi @networkblizzard,

Static MAC is used to fix the MAC address on this port and never ages out. It is normally combined with port security to ensure other devices cannot access the network via this port. When a port connects with a server or printer that is not usually moved, you can configure its MAC address as a static MAC address and set the "Max MAC Entry Number" of this port to 1 on the port security page.
