I'm having trouble enabling a em1 (1 Gbps) interface on RHEL 7. When trying to do so, I lose the connectivity to the machine and have to restart or access it via the console
===> lose connectivity and need to reboot the server (console doesn't show the GUI/desktop) :(
I've tried to delete the configuration file from /etc/sysconfig/network-scripts/ifcfg-em1 and recreate it. No progress.
em1: flags=4098<BROADCAST,MULTICAST> mtu 1500
ether f8:bc:12:4d:f3:00 txqueuelen 1000 (Ethernet)
RX packets 0 bytes 0 (0.0 B)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 0 bytes 0 (0.0 B)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
device interrupt 35
- The Link status on iDRAC shows up as UP but the ethtool reports that Link status is 'no' (meaning the link is down)
- NetworkManager is stopped and disabled.
- Few details about the the interface configuration:
ethtool -a em1
Pause parameters for em1:
ethtool -i em1
firmware-version: FFV7.8.16 bc 5720-v1.32
Additionally, here's an output from the ip a command
2: em1: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN qlen 1000

Can someone help please?
