So let us manually create a new configuration file for the new card.
#Scan for new hardware mac
As of now eth0 is already in connected state as per the output of ifconfig which can also match using the MAC details. SUBSYSTEM="net", ACTION="add", DRIVERS="?*", ATTR="1", KERNEL="eth*", NAME="eth1"Īs you see it shows two ethernet card details i.e.
In this file you can view the details of the newly connected Ethernet Card # PCI device 0x8086:0x100f (e1000) I have discussed about the working of this file in the below linkĭevice eth0 does not seem to be present, delaying initialization There is a file /etc/udev/rules.d/les which contains details about the connected ethernet card in your RHEL box. So as of now the new thernet card configuration is not reflected. TX packets:2964 errors:0 dropped:0 overruns:0 carrier:0 RX packets:2964 errors:0 dropped:0 overruns:0 frame:0 TX packets:58283 errors:0 dropped:0 overruns:0 carrier:0 RX packets:91992 errors:0 dropped:0 overruns:0 frame:0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 If we check the output of ifconfig # ifconfigĮth0 Link encap:Ethernet HWaddr 00:0C:29:B9:4D:D3 Now let us try to detect it without rebooting the OS I will just go ahead and add a new NIC card to my running RHEL machine. I have a Red Hat 6 vm created in my VMware Workstation Lab.
