Maximum number of interface in Bridge - VLAN

RouterOS General
1

Hello,
we bought for testing in our lab 4 x CRS326-24S+2Q+, and immediately upgraded to RouterOS 6.45.6.
While creating the first VLAN we notice that we can’t bridge all fiber interfaces together as tagged in the same VLAN. There is a limit at 30 interfaces with winbox ( version 3.20, 32 and 64 bits), while using terminal we can add that VLAN, but can’t edit again with winbox.
This means that 24 10Gb interfaces + 2x4 QSFP = 32 total interfaces.

Terminal command is
/interface bridge vlan
add bridge=bridge1 tagged=“sfp-sfpplus1,sfp-sfpplus2,sfp-sfpplus3,sfp-sfpplus4,sfp-sfpplus5,sfp-sfpplus6,sfp-sfpplus7,sfp-sfpplus8,sfp-sfpplus9,sfp-sfpplus10,sfp-sfpplus11,sfp-sfpplus12,sfp-sfpplus13,sfp-sfpplus14,sfp-sfpplus15,sfp-sfpplus16,sfp-sfpplus17,sfp-sfpplus18,sfp-sfpplus19,sfp-sfpplus20,sfp-sfpplus21,sfp-sfpplus22,sfp-sfpplus23,sfp-sfpplus24,qsfpplus1-1,qsfpplus1-2,qsfpplus1-3,qsfpplus1-4,qsfpplus2-1,qsfpplus2-2,qsfpplus2-3,qsfpplus2-4” untagged=ether1 vlan-ids=251

Is this limit only a “bug” of winbox or that VLAN will not work if added over terminal?

Thank you very much in advance
Francesco

I think that’s just another one of those really stupid Winbox limitations where once you hit the maximum height of the window/display you’re stuffed.
Why they can’t make these dialogs scrollable is beyond me.
It’ll work just fine using the command line, as you say, or use Webfig to do this.

That could be a nice improvement for winbox, maybe expand horizzontally if the windows size can support 2 or more columns.
An official answer from Mikrotik whuld be very appreciated.

I can confirm it’s a Winbox “bug”, there is the same limit to 30 entry also in the MST instance.
