Interface names can change if network drivers are updated, or if the port mode is changed. To determine the interface name that is currently in use for the X3522 interface:
- List all interfaces in the server:
# ip link - Search the output for the X3522
interface. It can be recognized by the MAC address that you read from the QR code
(see Get Details of the Card). For example:
3: enp1s0f2: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq portid 020000000000 state UP mode DEFAULT qlen 1000 link/ether 00:0A:35:0C:14:8E brd ff:ff:ff:ff:ff:ff- the line starting link/ether 00:0A:35:0C:14:8E identifies that this is the X3522 interface
- the interface name is enp1s0f2.
If this does not work, see Troubleshooting the Network Driver Load for help.
