Hi all,
I have an issue that ISR 4331 {ISR Software (X86_64_LINUX_IOSD-UNIVERSALK9-M), Version 16.9.1, RELEASE SOFTWARE (fc2)} creates an additional virtual access interface when a dialer is mapped to a gig interface when the E1 card (NAME: "NIM subslot 1/0", DESCR: "NIM-1MFT-T1/E1 - T1/E1 Serial Module") is connected. see bellow
interface GigabitEthernet0/0/1
