duplex (Management Ethernet)

To configure duplex mode operation on a Management Ethernet interface, use the duplex command in interface configuration mode. To return the interface to autonegotiated duplex mode, use the no form of the duplex command.

duplex {full | half}

no duplex

Syntax Description

full

Configures the Management Ethernet interface to operate in full duplex mode.

half

Configures the Management Ethernet interface to operate in half duplex mode.

Command Default

Autonegotiates duplex operation

Examples

This example shows how to configure the Management Ethernet interface to operate in full duplex mode: 


RP/0/RP0/CPU0:router(config)# interface mgmtEth 0/
RP0/CPU0/0
RP/0/RP0/CPU0:router(config-if)# duplex full

This example shows how to configure the Management Ethernet interface to operate in half duplex mode: 


RP/0/RP0/CPU0:router(config)# interface mgmtEth 0/RP0/CPU0/0
RP/0/RP0/CPU0:router(config-if)# duplex half

This example shows how to return a Management Ethernet interface to autonegotiated duplex mode: 


RP/0/RP0/CPU0:router(config)# interface mgmtEth 0/RP0/CPU0/0
RP/0/RP0/CPU0:router(config-if)# no duplex

interface MgmtEth

To enter interface configuration mode for the Management Ethernet interface, use the interface MgmtEth command in XR Config mode. To delete a Management Ethernet interface configuration, use the no form of this command.

interface MgmtEth interface-path-id

no interface MgmtEth interface-path-id

Syntax Description

interface-path-id

Physical interface or virtual interface.

Note

 

Use the show interfaces command to see a list of all interfaces currently configured on the router.

For more information about the syntax for the router, use the question mark (? ) online help function.

ipv6 address autoconfig

The ipv6 address autoconfig command is used to configure IPv6 addresses or prefix on the interface. This command enables IPv6 processing on the interface. To remove all manually configured IPv6 addresses from an interface, use the no ipv6 address command without arguments.

The IPv6 Stateless Address Auto Configuration (SLAAC) is used when a site is not particularly concerned with the exact addresses the hosts use, as long as they are unique and can be routed. IPv6 auto configuration is disabled by default. To enable IPv6 SLAAC on Management interface, use the ipv6 address autoconfig command on the Management interface configuration mode. To disable auto configuration on the Management interface, use the no form of the command.

ipv6 address { [ ipv6addr ] | [ ipv6-prefix/prefix length ] | [ autoconfig ] }

no ipv6 address { [ ipv6addr ] | [ ipv6-prefix/prefix length ] | [ autoconfig ] }

Syntax Description

ipv6addr

(Optional) Specify the IPv6 address.

ipv6-prefix/prefix length

(Optional) Specify the IPv6 prefix and the prefix length preceded by a slash [/].

autoconfig

(Optional) Enable IPv6 stateless address auto configuration (SLAAC) on Management interface.

Note

 

The autoconfig option is only available for Management Interfaces.

Command Default

No default behavior or values

Command Modes

Command History

Release

Modification

Release 6.3.1

This command was introduced.

Usage Guidelines

In the ipv6 address interface configuration command, you can enter the ipv6addr or ipv6-prefix/prefix length variables with the address specified in hexadecimal using 16-bit values between colons. The prefix length variable (preceded by a slash [/]) is a decimal value that shows how many of the high-order contiguous bits of the address comprise the prefix (the network portion of the address).

The router will automatically configure an IPv6 link-local address on the interface, and enable the interface for IPv6 processing, and trigger IPv6 Neighbor Discovery (ND) auto configuration functionality in ND. Once the Management interface is in no shut state and ipv6 address autoconfig configuration is enabled, you will receive Router Advertisement (RA) on Management interface and get prefix and other information.

Examples

The following example shows how to configure the IPv6 address based on the IPv6 prefix 2001:0DB8:c18:1::/64:


RP/0/RP0/CPU0:router# configure
RP/0/RP0/CPU0:router(config)# interface gigabitEthernet 0/2/0/0
RP/0/RP0/CPU0:router(config-if)# ipv6 address 2001:0DB8:c18:1::/64

The following example shows how to enable IPv6 auto configuration on router: 


RP/0/RP0/CPU0:router# configure
RP/0/RP0/CPU0:router(config)# interface mgmtEth 0/RSP0/CPU0/0
RP/0/RP0/CPU0:router(config-if)# ipv6 address autoconfig
