C25/C26 setting a VLAN

Moving camera traffic to their own VLAN. Settup up a new C71 and setting the VLAN under the 802.1Q section then tagging the camera VLAN and leaving the default VLAN as unmanaged they work fine.
Setting up a C26 I can not find the 802.1Q option, I did go under the Current Configuration and add these lines to the Network section under the line ETH0_ADD_DEFAULT=on
This did not help. Is there a way to make the VLAN’s work correctly on the c2* series?

Thanks, Tim
