There are multiple tutorials online on how to connect a modem to a 5G core
with multiple PDUs using mbimcli (like,

Essentially in mbimcli one can specify a session id, as part of the access
string. This session ID is then mapped to a VLAN ID, which is mapped to a
virtual interface on top of the modem network interface. In short,
something like this:

ip link add wwan0.1 link wwan0 type vlan id 1
ip link add wwan0.2 link wwan0 type vlan id 2
mbimcli -p -d /dev/cdc-wdm0 --connect=apn=apnA,session-id=1,ip-type=ipv4
--no-close --no-open=42
mbimcli -p -d /dev/cdc-wdm0 --connect=apn=apnB,session-id=2,ip-type=ipv4
--no-close --no-open=42

Is it possible to achieve the same result using mmcli, or the ModemManager

Thank you,
