Hi Team,
As I am using Mellanox MT28800 Family [ConnectX-5 Ex], I installed MLNX_OFED software in Ubuntu 22.04 PC with the kernel version 6.2.0-35-generic. In ip a, I could see the interfaces listed,
3: enp1s0p0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN group default qlen 1000
link/ether 04:3d:52:a1:12:bc brd ff:ff:ff:ff:ff:ff
4: enp1s0p1: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN group default qlen 1000
link/ether 04:3d:52:a1:12:bd brd ff:ff:ff:ff:ff:ff
When I try to make interface up, the link shows DOWN always [ I have connected QSFP28 with loopback ].
sudo ifconfig enp1s0p0 192.168.6.1 up
sudo ifconfig enp1s0p0 192.168.6.1 up
ip a
3: enp1s0p0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN group default qlen 1000
link/ether 04:3d:52:a1:12:bc ff:ff:ff:ff:ff:ff
inet 192.168.6.1/24 brd 192.168.6.255 scope global enp1s0p0
valid_lft forever preferred_lft forever
4: enp1s0p1: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN group default qlen 1000
link/ether 04:3d:52:a1:12:bd brd ff:ff:ff:ff:ff:ff
inet 192.168.6.2/24 brd 192.168.6.255 scope global enp1s0p1
valid_lft forever preferred_lft forever
Please let me know why the Link status shows DOWN always? Even after the interface is configured for UP?
