interface
To enter Interface configuration mode in order to configure an interface, use the interface Global Configuration mode command.
Syntax
interface interface-id
Parameters
interface-id—Specifies an interface ID. The interface ID can be one of the following types: Ethernet port, port-channel, VLAN, range, OOB, IP interface or tunnel.
Default Configuration
None
Command Mode
Global Configuration mode
Examples
Example 1—For Ethernet ports:
switchxxxxxx(config)# interface te1/0/1 switchxxxxxx(config-if)# |
Example 2—For port channels (LAGs):
switchxxxxxx(config)# interface po1 switchxxxxxx(config-if)# |
interface range
To execute a command on multiple ports at the same time, use the interface range command.
Syntax
interface range interface-id-list
Parameters
interface-id-list—Specify list of interface IDs. The interface ID can be one of the following types: Ethernet port, VLAN, or port-channel
Default Configuration
None
Command Mode
Interface (Ethernet, Port Channel, VLAN) Configuration mode
User Guidelines
Commands under the interface range context are executed independently on each interface in the range. If the command returns an error on one of the interfaces, it does not stop the execution of the command on other interfaces.
Example
switchxxxxxx(config)# interface range te1/0/1-4 switchxxxxxx(config-if-range)# |
shutdown
To disable an interface, use the shutdown Interface Configuration mode command.
To restart a disabled interface, use the no form of this command.
Syntax shutdown no shutdown
Parameters
This command has no arguments or keywords.
Default Configuration
The interface is enabled.
Command Mode
Interface Configuration mode
User Guidelines
The shutdown command set a value of ifAdminStatus (see RFC 2863) to DOWN.
When ifAdminStatus is changed to DOWN, ifOperStatus will be also changed to DOWN.
The DOWN state of ifOperStatus means that the interface does not transmit/receive messages from/to higher levels. For example, if you shut down a VLAN, on which an IP interface is configured, bridging into the VLAN continues, but the switch cannot transmit and receive IP traffic on the VLAN.
Notes:
- If the switch shuts down an Ethernet port it additionally shuts down the port MAC sublayer too.
- If the switch shuts down a port channel it additionally shuts down all ports of the port channel too.
Examples
Example 1—The following example disables te1/0/4 operations.
switchxxxxxx(config)# interface te1/0/4 switchxxxxxx(config-if)# shutdown switchxxxxxx(config-if)# |
Example 2—The following example restarts the disabled Ethernet port.
switchxxxxxx(config)# interface te1/0/4 switchxxxxxx(config-if)# no shutdown switchxxxxxx(config-if)# |
Example 3—The following example shuts down vlan 100.
switchxxxxxx(config)# interface vlan 100 switchxxxxxx(config-if)# shutdown switchxxxxxx(config-if)# |
Example 4—The following example shuts down tunnel 1.
switchxxxxxx(config)# interface tunnel 1 switchxxxxxx(config-if)# shutdown switchxxxxxx(config-if)# |
Example 5—The following example shuts down Port Channel 3.
switchxxxxxx(config)# interface po3 switchxxxxxx(config-if)# shutdown switchxxxxxx(config-if)# |
operation time
To control the time that the port is up, use the operation time Interface (Ethernet, Port Channel) Configuration mode command. To cancel the time range for the port operation time, use the no form of this command.
Syntax operation time time-range-name no operation time
Parameters
- time-range-name—Specifies a time range the port operates (in up state). When the Time Range is not in effect, the port is shutdown. (Range: 1–32 characters)
Default Configuration
There is no time range configured on the port authorized state.
Command Mode
Interface (Ethernet, Port Channel) Configuration mode
User Guidelines
It is recommended to disable spanning tree or to enable spanning-tree PortFast mode on 802.1x edge ports (ports in auto state that are connected to end stations), in order to proceed to the forwarding state immediately after successful authentication.
Example
The operation time command influences the port if the port status is up. This command defines the time frame during which the port stays up and at which time the port will be shutdown. While the port is in shutdown because of other reasons, this command has no effect.
The following example activates an operation time range (named “morning”) on port te1/0/1.
switchxxxxxx(config)# interface te1/0/1 switchxxxxxx(config-if)# operation time morning |
