CRS3xx CVID Stacking

Tue Nov 06, 2018 12:28 pm

Hi.

I am trying to configure CVID stacking as per this guide. (https://wiki.mikrotik.com/wiki/Manual:I ... 8Q-in-Q.29)

sfpplus1 is my uplink. So I am trying to stack vlan-id=5 inside of vlan-id=3001, however I cannot pickup anything on the other side of the link, does anyone see something wrong with this config?
Code: Select all
/interface bridge
add  auto-mac=no name=bridge protocol-mode=none \
    vlan-filtering=yes
    
/interface bridge port
add bridge=bridge comment=interface=ether24 pvid=5 tag-stacking=yes
add bridge=bridge interface=sfp-sfpplus1

/interface bridge vlan
add bridge=bridge tagged=sfp-sfpplus1,bridge  vlan-ids=3001
add bridge=bridge tagged=bridge,sfp-sfpplus1 untagged=ether24 vlan-ids=5

Im running into the same problem, im now trying svid with ether-type=0x88a8, maybe that helps you get it up.

6.43.14 long - term.

see following:

Currently without the svid im running vlan aware bridge configuration with ether type 0x8100. I thought I needed a second bridge for that, but I cant add ether4 to both bridges. You got a suggestion maybe?

Prior to the VLAN aware bridge configuration, you used to be able to achieve this (or at least something similar) by using 'egress vlan-translation' and matching on the S/C-VLAN and re-writing a 'NEW' S/C-VLAN.

Using the new configuration method, i have yet to find a way to insert an inner tag from within one outer tag, into another outer tag. (.e.g)

Ingress - > (ether1) 1000:101 (SWITCH) Egress -> (ether2) 1001:101
