Hi,
I have a problem with 100Mbps (155M) SFP on MikroTik CRS328-4C-20S-4S+. They should work on this model in all SFP ports according to this:
https://wiki.mikrotik.com/wiki/MikroTik_wired_interface_compatibility#SFP_interface_compatibility_with_100M_optical_transceivers
SFP interface on the listed devices is compatible with fast ethernet fiber links.
Compatible devices (interface):
CCR1009-7G-1C (combo1)
CCR1009-7G-1C-1S+ (combo1)
CRS106-1C-5S (combo1)
CRS328-4C-20S-4S+ (combo1 - combo4 and SFP1 - SFP20)
LHG XL 52 ac
RBD22/D23/mANTBox 52 15s/NetMetal ac²
For testing purposes I’ve tried to connect two SFP ports (sfp1 and sfp9 in example below) that belong to two separate VLANs:
# 2023-08-28 09:33:43 by RouterOS 7.11
# software id = N882-J2R7
#
# model = CRS328-4C-20S-4S+

But there is no communication between them (tried to ping 192.168.89.1 from combo1 port).
Also tried to force 100M on both SFP ports:
/interface ethernet
set [ find default-name=sfp1 ] auto-negotiation=no speed=100Mbps
set [ find default-name=sfp9 ] auto-negotiation=no speed=100Mbps
This also doesn’t work, except that the links at the SFP ports in MikroTik have lit up and the status “link ok” is in the SFP interface status. Unfortunately, there is no IP communication. TX counter at port status is increasing, but RX is zero.
No firewall applied, no (R)STP on bridge ports.
Same config tested with another different (from other manufacturer) pair SFP 100MBps (155Mbps) and communication also doesn’t work.
Same config tested with few different pair SFP 1Gbps (1,25G) and communication works good.
Tested pair SFP 100MBps (155Mbps) checked on another device (simple media converter Planet IGT-805AT) and works good (same patchord).
Screenshot in attachment:
- sfp1 status while patchord is disconnected
- sfp1 status while it is connected to sfp9 (autonegotiation)
- sfp1 status while it is connected to sfp9 (forced 100M)

Any suggestions this would work ?
