If I am not mistaken, this is the IMM's USB interface to the OS (or vice versa). This is used by the advanced settings utility (ASU) to send commands from the local OS to the IMM. In order to disable it, you can either manually do it in the uEFI interface, you may be able to do it from the IMM web or SSH interface, or you can use ASU. For example, on an nx350 m5, the setting is " IMM.LanOverUsb=Enabled."
If you run asu locally, you can probably find the setting by running 'asu64 show all | grep -I usb' or with xCAT, you can use 'pasu node show all | grep -I usb'. To change it, rung: locally: asu64 set IMM.LanOverUsb Disabled xCAT: pasu node set IMM.LanOverUsb Disabled Regards, Christian Caruthers Lenovo xESS IT Consultant Mobile: 757-289-9872 -----Original Message----- From: Andy Loftus [mailto:[email protected]] Sent: Wednesday, September 07, 2016 3:54 PM To: [email protected] Subject: [xcat-user] Virtual eth interface on Lenovo X3550 Server make/model: Lenovo X 3550 Xcat version: Version 2.11.1 OS: CentOS Linux release 7.2.1511 (Core) On 34 of 47 nodes, after installing a new OS, there is a virtual ethernet interface that looks like: # ip addr show ... enp0s20u1u5: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UNKNOWN qlen 1000 ... There used to be a 169.254.x.x address associated with it but I think it get's removed by the postscript 'confignics -r', although the interface remains. Anyone know where this comes from and/or how to prevent it?
