RBM33g, how to bind the hardware slot lte0 to the Winbox's LTE1 label, and lte1 to the LTE2 label?

Mon Jul 12, 2021 1:56 pm

Hey!

I need to bind the lte0 hardware slot to the lte1 label in Winbox and the lte1 hardware slot to the lte2 label in Winbox.
this is necessary to eliminate confusion when configuring the router remotely.

How can i do this?


thanks!

bind?

everytime name change?

what name you get?

provide results of
/int lte export verbose hide-sensitive
for furter analysis

internally the name are bind to original equipment hardware MAC

Hello!

I will try to describe the problem in more detail.
there are two modem slots on the router board. they are signed as PCIe0 and PCIe1.
when SIM cards are plugged into each modem, in Winbox in the interfaces the modem that is plugged into PCIe0 is displayed as lte1, and the one that is plugged into PCIe1 is displayed as lte2.
but now the SIM card is only plugged into a modem that is plugged into PCIe1, but in Winbox this modem is displayed as lte1.

the output:
[admin@RBM33G-slave] > /int lte export verbose hide-sensitive
# jul/12/2021 11:02:38 by RouterOS 6.46.8
# software id = 2MJG-KT1Q
#
# model = RBM33G
# serial number = A2FD0E8D2494

Is like the lte work differently,
the MAC address are both mac-address=AC:FF:FF:00:00:00
and I do not understand how mikrotik work on this case

Since the two MAC addresses are not in the same L2 segment, it doesn't matter for network operation that they are identical - e.g. two /interface vlan hooked to the same bearer interface share the same MAC address as well and it causes no confusion). Whether they are used as equipment identifier is questionnable, as the AC:FF:FF:00:00:00 looks "too systematic" to me, and it is not a consequence of some conflict on this particular device - on a wAP LTE kit which only has a single PCIe slot, an R11e-LTE device shows the same MAC address too, and the serial number is 000000000000.

Similarly, both R11e-LTE6 modules I could check, each in another RouterBoard, have the same MAC address AC:50:43:1A:EE:FD (and serial number 000000000000 as well).

What is worse is that the configuration export clearly omits something, because a [find] without any match parameters returns a list of all interfaces, so each of the two set rows would change the settings of both interfaces (when both are present), but it apparently doesn't. So there is some kind of bug in the discovery process.

What does /system resource usb print detail show when both SIMs are inserted, and what does it show when the one for PCIe 0 is not inserted?

Whether they are used as equipment identifier is questionnable
If you put one or more usb ether/wifi dongle / powerline / MiniPCI-e card, the wlanX / etherX /etc. internal default name remain everytime the same (on same device)
The board memorize MAC<->interface name and you can change the name like ether6 -> pippo but still memorized as default-name

This is not exported with /export but is keeped inside internal database or backup.

You can experiment with it on CHR / x86 on virtualized hardware.

I've asked for two prints (with both SIMs inserted and with only one). But as you can see, everything is the same except from the USB address.

As you can see here, the only difference is the USB address. Whether RouterOS links the LTE interface name to the USB address is a question for developers.

Selection should be done by IMEI of lte device, only this give us option to identify one module from other.
