Some history. I use mikrotik and routerboard hw from 2004 because and very good choice. Routerboard hw and routeros very stable and handy and well documented.
I have some problems in the past, and i see: mikrotik representative very aggressive in communication, and think routeros always perfect, and routerboard also..
I use these devices to backhaul and interconnect our network. Works fine. Thanks Mikrotik.
But now i want to use 750G as switch and router on my network. I need wire speed switching (1Gbit/s) good stability, and durability. 750G has a switch chip, switch chip can speak .1q vlan, etc.
I bought some devices(10+) and put to our network for environmental test. Works fine, but i found a problem at switch chip backpressure, this problem submitted to mikrotik support and under investigate (very strange communication again)
Now i want to use switch chip vlan. I found only questions on forum. Documentation found from mikrotik on new wiki (http://wiki.mikrotik.com/wiki/Switch_Chip_Features
) but this documentation very imperfect not pair with any routeros version and have missing parts, and some places give wrong information.
I found documentation about rb250GS and (because same chip, and same configuration parameters) use to set 750G parameters, but some parameter can't be set because missing this feature from routeros. The switch chip can do, but i can't be set from ROS. Debugging not possible because switch chip not debug friendly.
State: i can't use 750G switch chip as a vlan aware hw switch.
1, i can't set one port untagged traffic on a vlan
2, i can't set untagged and tagged traffic on same port.
Example undocumented setting:
vlan-header exists in interface ethernet switch port menu not documented (but works, if i set add-if-missing always set vlan 0 to non .1q packets (this is not perfect also), always-strip also work)
Switch cpu port not appear as separate switch port, and can't apply any setting with this port.
I think interface ethernet switch rule completely wont work. (i can't debug because i can't put mirror-source on cpu port because in 4.x this is not separate port)
Switch port vlan-header option not work, but now cpu is a separate device.
(example undocumented feature: independent-learning)
I can't specify default vlan on a port (for untagged traffic)
I can't force vlan tagging with port own default vlan if vlan tag missing in incoming traffic.
These problems based on current 750G and 250GS capability, if any options changed may cause other problems.
Please mikrotik communicate clearly:
1, When make available same vlan features (i don't think web interface) on 750G as 250GS (hw can do it)
2, Where is a documentation on available features?
And please, if any user can have more information on switch chip vlan are welcome
