Table 65-2. show hardware rpm number mac Output Description 1000Base-T Control Automatic MDI Crossover Control Automatic MDI Crossover State 1000Base-T requires auto-negotiation. The IEEE Ethernet standard does not support setting the speed to 1000 Mbps with the speed command without auto-negotiation. C-Series line cards support both full-duplex and half-duplex 1000BaseT. Indicates whether Automatic MDI crossover mode is enabled or disabled Indicates whether Automatic MDI crossover state is crossover or normal. Usage Information Use the show hardware interface interface phy command when you are troubleshooting a link issue, such as when the show interfaces interface command is reporting an auto-negotiation mismatch (there is an "Auto-neg Error" string in the output, as shown below. Figure 65-11. Auto-negotiation Mismatch Example Force10#show interfaces gigabit 0/3 GigabitEthernet 0/3 is up, line protocol is down Hardware is Force10Eth, address is 00:01:e8:07:16:b3 Internet address is not set MTU 1554 bytes, IP MTU 1500 bytes LineSpeed auto, Mode full duplex, Auto-neg Error ARP type: ARPA, ARP Timeout 04:00:00 Last clearing of "show interface" counters 04:39:17 [output omitted] The no auto-negotiation command disables auto-negotiation on an interface. Dell Force10 recommends keeping auto-negotiation enabled. If the remote interface is not configured for auto-negotiation, the Dell Force10 interface can detect the speed at which the remote device is operating by the type of electrical signal that is arriving. If the local and remote interfaces are configured differently for auto-negotiation-for example, one side is configured for auto-negotiation and the other side is configured for a particular speed-the link does no not come up. Both sides of the link must be configured for auto-negotiation (recommended) or else the same speed. 1000Base-T requires auto-negotiation. The IEEE Ethernet standard does not support setting the speed manually to 1000 Mbps. C-Series Diagnostics and Debugging | 1511

Usage

Information

Use the

show hardware interface

interface

phy

command when you are troubleshooting a link

issue, such as when the

show interfaces

interface

command is reporting an auto-negotiation

mismatch (there is an “Auto-neg Error” string in the output, as shown below.

Figure 65-11.

Auto-negotiation Mismatch Example

The

no auto-negotiation

command disables auto-negotiation on an interface. Dell Force10

recommends keeping auto-negotiation enabled.

If the remote interface is not configured for auto-negotiation, the Dell Force10 interface can detect the

speed at which the remote device is operating by the type of electrical signal that is arriving.

If the local and remote interfaces are configured differently for auto-negotiation—for example, one

side is configured for auto-negotiation and the other side is configured for a particular speed—the link

does no not come up. Both sides of the link must be configured for auto-negotiation (recommended) or

else the same speed.

1000Base-T requires auto-negotiation. The IEEE Ethernet standard does not support setting the speed

manually to 1000 Mbps.

1000Base-T Control

1000Base-T requires auto-negotiation. The IEEE Ethernet standard does not

support setting the speed to 1000 Mbps with the

speed

command without

auto-negotiation. C-Series line cards support both full-duplex and half-duplex

1000BaseT.

Automatic MDI Crossover

Control

Indicates whether Automatic MDI crossover mode is enabled or disabled

Automatic MDI Crossover

State

Indicates whether Automatic MDI crossover state is crossover or normal.
