Configuring Virtual MAC Address
To configure the remote virtual MAC address in the DNN profile, use the following sample configuration:
config
profile dnn dnnprofile_name
virtual-mac mac_address
exit
NOTES:
-
profile dnn dnnprofile_name : Specify the DNN profile name. dnnprofile_name must be an alphanumeric string.
-
virtual-mac mac_address : Specify the remote virtual MAC address used to generate interface ID for UE. mac_address must be a string in the MAC address pattern.
In release 2021.01 and later, the SMF generates unique 64-bit interface ID which is non-EUI-64 format by using SBI VIP address and CommonId of the subscriber.
That is, IPv6 interface ID = VIP-IP (4 bytes) + CommonId (4 bytes)
By default, virtual-mac CLI command is now disabled under DNN configuration.
