CLI: Interface
You can use the interface command to configure the interface address and other IPInternet protocol networking settings.
NOTE
Configuring Interface address
interface <inf> ip address
interface <inf> ipv6 {address|enable}
interface
<inf> {dhcp|alias|comment|duplex|speed|mtu|shutdown}
To add or remove an IPv4 address and netmask for the specified interface:
[no] interface <inf> ip address <IPv4 addr> <netmask>
netmask- Specify the netmaks as dotted quad format (e.g. 255.255.255.0) or as a netmask length after a slash (e.g. /24)
To enable IPv6 on the specified interface:
[no] interface <inf> ipv6 enable
To add or remove an IPv6 address for the specified interface:
[no] interface <inf> ipv6 address <IPv6 addr>/<len>
<IPv6 addr>/<len>- e.g. 2001:db8:1234::5678/64
To enable IPv6 stateless address autoconfiguration (SLAAC) on the specified interface:
[no] interface <inf> ipv6 address autoconfig [default | privacy]
default- Enables learning default routesprivacy- Enabled autoconfiguration privacy extensions
To enable DHCPDynamic Host Configuration Protocol on the specified interface:
interface <inf> dhcp
To renew DHCP on the specified interface:
interface <inf> dhcp renew
To configure an IPv4 alias on the specified interface:
interface <inf> alias <alias index> ip <IPv4 addr>
To add a comment to the specified interface:
interface <inf> comment <comment>
To configure the duplex of the specified interface:
interface <inf> duplex {half|full|auto}
To configure the speed of this interface:
interface <inf> speed {10|100|1000|auto}
EXAMPLE
Set the speed and duplex interface settings for eth2.
interface eth2 speed 100
interface eth2 duplex full
To configure the MTUMaximum Transmission Unit of this interface:
interface <inf> mtu <mtu>
To disable the specified interface:
interface <inf> shutdown
Viewing interface running state and configuration
To display information about the running state for the interfaces:
show interfaces [<inf>] [brief]
<inf>- Optionally, indication that you want information for a single interface; otherwise information for all interfaces will be shownbrief- Optionally, indicate that you want brief details; otherwise the information will be detailed.
To display the current configuration for all interfaces:
show interfaces configured
To display a summary of the running state for all interfaces, including bridge and role information:
show interfaces summary
