Mikrotik vlan - Cisco 3560 -Xseries

[45664]

Hello,

I am trying to learn so excuse my lack of knowladge!

I am trying to receive media stream from my ISP via fiber converter - mikrotik - my cisco switch.

According to them they have config their mikrotik ports (2 of them) with layer2 vlans for two different channels.

i dont know they config on their device (mikrotik) but as far as my cisco i have 10 ports as follow;

interface GigabitEthernet 0/1
switchport access vlan 998
spanning-tree portfast \ same for the other ports 

Whenever i plug my cables from their mikrotik port2 in this case i receive no signal and the port on my switch turns amber and it stays as long as it is connected... 

I have tried removing the spanning tree portfast but didnt change anything

My question is what could it be, should the vlan be on the same vlanID or

is there anything with root - designated thing or

I should add something to the mix in order to receive the stream?

Many thanks

Hello,

amber usually means the port is blocked by spanning tree and not forwarding data.

I don't know how your Mikrotik is configured, by try and set the Cisco to be the root for your VLAN:

spanning-tree vlan 998 root

Georg,
will this change anything while this is my production data switch and having it as root will is cause any harm? i have two other switches directly connected

thanks

Hello,

don't change anything. First we need to see what your network looks like. Can you post a schematic drawing ?

Is VLAN 998 propagated to all the other switches ?

Now this is pretty much how it is, i have no problems with other to encoders (Encoder 2 and 3)

the problem i have is Encoder 1 which goes via Miktorik Layer2 Vlan,

If i bypass Mikrotik and connect my dataswitch directly to FiberCon, it is working fine.

My port connected to the mirkrotik port is conf. as follow;

interface GigabitEthernet0/10
switchport access vlan 998
spanning-tree portfast (i have tried no spanning-tree portfast)

it didnt change anything
