I'm hoping someone can quickly tell me if an observation I just made is expected or not. I'm running Merlin's 386.1 beta 1 on an RT-AC88U.

I connect via SSH and send this command

nvram show | grep vlan.*ports | sort

This is the response

size: 65536 bytes (65536 left)
vlan1ports=0 1 2 3 5 7 8*
vlan2ports=4 8u


I did not expect to already have two VLAN's (VLAN1 and VLAN2). I also did not expect to see port 6 missing. Is this normal default behavior? Or perhaps something configures the RT-AC88U while it is running?

I am not running any custom scripts. In fact I am studying the work of @netaddict to figure out how to configure separate VLAN's -- but just to be clear, I have not changed anything yet. I just sent a few commands to look at how things are currently configured and I am surprised by what I observed.

This command

robocfg show

Returns this

Switch: enabled
Port 0: 1000FD enabled stp: none vlan: 1 jumbo: off mac: d0:03:4b:20:a5:86
Port 1: 1000FD enabled stp: none vlan: 1 jumbo: off mac: 18:b4:30:92:bb:52
Port 2: 1000FD enabled stp: none vlan: 1 jumbo: off mac: 90:dd:5d:f2:bd:85
Port 3: 1000FD enabled stp: none vlan: 1 jumbo: off mac: 18:b4:30:8f:d7:e2
Port 4: 1000FD enabled stp: none vlan: 2 jumbo: off mac: 56:e0:32:75:30:f5
Port 5: 1000FD enabled stp: none vlan: 1 jumbo: off mac: 00:00:00:00:00:00
Port 7: 1000FD enabled stp: none vlan: 1 jumbo: off mac: 00:00:00:00:00:00
Port 8: 1000FD enabled stp: none vlan: 2 jumbo: off mac: 10:7b:44:af:72:50
VLANs: BCM5301x enabled mac_check mac_hash
1: vlan1: 0 1 2 3 5 7 8t
2: vlan2: 4 8u


I believe port 0 is the WAN connection which is physically connected, and I have physical connections on ports 1, 2, 3 and 4. Ports 5, 6, 7, and 8 are physically disconnected. I would expect port 6 to be listed, perhaps with a mac of 00:00:00:00:00:00 and I would expect port 8 to also have that mac address since nothing is connected.

Looking at the bridge status, using this command

brctl show

Returns this state

bridge name bridge id STP enabled interfaces
br0 8000.107b44af7250 yes vlan1
eth1



Thanks in advance for any thoughts.
