Issue
- All our nic cards are autonegotiating under heavy load
- High-volume NICs that lose sync when they are in auto-detect mode, and often renegotiate at the incorrect speeds and/or duplex.
- The network and backup team came to us asking to force to full 1gb the backup nic cards
Environment
- Red Hat Enterprise Linux
- Gigabit network interfaces with auto-negotiation on
