HIi,
After upgrading to RouterOS 7.23.1 on my CHR instance running on Proxmox (QEMU Q35), I get the following warning on my WAN interface:
same mac-address as sfp-sfpplus1
Environment:
-
RouterOS 7.23.1 (stable)
-
CHR on Proxmox 8.x / QEMU Q35
-
Board: CHR QEMU Standard PC (Q35 + ICH9, 2009)
-
2 virtual NICs (virtio)
Problem:
A phantom sfp-sfpplus1 interface appears to be created internally by RouterOS CHR and shares the same MAC address as my WAN interface (ether2). This interface cannot be found, modified or removed:
-
/interface print where name="sfp-sfpplus1"→ empty -
/interface ethernet remove sfp-sfpplus1→ bad command name remove -
/interface ethernet set sfp-sfpplus1 mac-address=...→ no such item
Workaround:
Rollback to 7.22 — warning disappears.
Note:
I understand the MAC conflict warning was intentionally added in 7.23 (interface - show warning when same MAC address is used on more than one virtual interface), but it seems CHR on QEMU automatically generates this phantom SFP interface which triggers the warning incorrectly.
Please investigate. Thank you.
