SG300-10P to SG300-28P Not Passing Tagged Traffic on Trunk Port

Bruce Speidel
Level 1
Level 1

I have two switches a 10 Port and a 28 Port.  I need a single trunk on each switch so that I can tag two VLAN's of traffic.   I must admit I have fretted over this configuration for a couple months.  

For the initial configuration, I have setup all interfaces as Access (although I am doubting this).   Both switches are configured as layer 2 only.   (have thought to try layer 3 - but have not ventured down this path yet).    Each port's Administrative PVID matches the vlan.

 

For my VLAN's, I have one on 192.168.0.0/24 with the microtik router on .1.  This is setup as the default vlan1, although I am doubting my thoughts I should have done this.   On this same Vlan1, I have Linksys AX4200 (from the MX12600 set) wired to the internet port.   I setup the Linksys internet port as static 192.168.0.100.   

 

The second Vlan (2) has the ethernet port of the AX4200 wired to an assigned port.   This network behind the Velop mesh is 192.168.1.0/24.   It has a DHCP pool and is also a router.  

 

In the switch configs - here is the setup

For the 28P (all power-over-eithernet has been disabled), port assignments

Ports 1-12 & 25 are all on vlan1

Ports 13-25 & 26 are all on vlan2

Port 27 is setup as vlan3 but nothing is wired.

Port 28 is the Trunk

 

For the 10P switch:

Ports 1-3 are assigned to Vlan1

Ports 4-9 are assigned to Vlan2

Port 10 is the Trunk

 

In my testing so far, I have found that every port on both switches assigned to vlan1 work flawlessly.   I can get a DHCP assignment or assign a static address to 192.168.0.0/24 just fine on both switches from the microtik router on 192.168.0.1.

 

However, on the Velop mesh network, this is where the trouble begins.  On the 28P switch, I can get a DHCP assignment in vlan2 to assign a DHCP address just fine and also configure a static port just fine in 192.168.1.0/24.   HOWEVER, on the 10P switch, in vlan2, ports 4-9, I cannot get anything to work, regardless if it is a DHCP assignment or a static assignment.

The one thing I have been questioning in my mind is the Administrative VLAN assignment for the trunks.  They are:  1T, 4095P.   I think this may be the mistake, but I cannot find a way to correct it.

 

Any advise would be greatly appreciated.   I will be happy to share the downloaded configs - but think with SSH keys I added and my personal userid's allowing me to ssh into each switch, I would hold off unless someone asks.  

Thanks, Bruce Speidel

Make sure both the switches have VLAN 2 created 

 

add below config where the ports are connected each other :

 

example :

Switch 10P

# interface Gig1(Port 10)

# switchport mode trunk
# switchport trunk allowed vlan add all

 

Switch 28P

 

# interface Gig1  (Port 28)

# switchport mode trunk
# switchport trunk allowed vlan add all

 

VLAN created on both switches (if any smart port enable remove)

 

still not working

 

post-show run from both the switches?
