Configuring Gigabit Ethernet Interfaces
Purpose
• bidirectional—Enables the sending of flow control
pause frames in egress and the processing of received
pause frames on ingress.
(Optional) Sets the MTU value for the interface.
• The default is 1514 bytes for normal frames and 1518
bytes for 802.1Q tagged frames.
• The range for Gigabit Ethernet and 10-Gigabit
Ethernet mtu values is 64 bytes to 65535 bytes.
(Optional) Sets the MAC layer address of the Management
Ethernet interface.
• The values are the high, middle, and low 2 bytes,
respectively, of the MAC address in hexadecimal.
The range of each 2-byte value is 0 to ffff.
(Optional) Enables autonegotiation on a Gigabit Ethernet
interface.
• Autonegotiation must be explicitly enabled on both
ends of the connection, or speed and duplex settings
must be configured manually on both ends of the
connection.
• If autonegotiation is enabled, any speed or duplex
settings that you configure manually take precedence.
The negotiation auto command is available on
Note
Gigabit Ethernet interfaces only.
Removes the shutdown configuration, which forces an
interface administratively down.
Saves configuration changes.
• When you issue the end command, the system
prompts you to commit changes:
Uncommitted changes found, commit them before
exiting(yes/no/cancel)?
[cancel]:
• • Entering yes saves configuration changes to the
running configuration file, exits the configuration
session, and returns the router to XR EXEC
mode.
• Entering no exits the configuration session and
returns the router to XR EXEC mode without
committing the configuration changes.
