HP DL360 eth2 link down issue

[Sabir009]

Hi All,

Does anyone know about a know issue with HP DL 360 eth2 interface. The eth2 interface has been assigned with an IP address but the link never comes up.
We have changed the cables / swapped the eth0 and eth2 cables, but the link still shows down on eth2.
