1000Base-T
Control
1000Base-T requires auto-negotiation. The IEEE Ethernet standard does not
support setting a speed to 1000 Mbps with the speed command without auto-
negotiation. E-Series line cards support both full-duplex and half-duplex
1000BaseT.
Phy Specific
Control
Values are:
● 0 - Manual MDI
● 1 - Manual MDIX
● 2 - N/A
● 3 - Auto MDI/MDIX
Phy Specific
