Chapter 2 Configuring Basic Interface Parameters Information About the Basic Interface Parameters Send document comments to [email protected] Note When you choose Ethernet or port channel as the interface type, the port profile is in the default mode which is Layer 3. Enter the switchport command to change the port profile to Layer 2 mode. You inherit the port profile when you attach the port profile to an interface or range of interfaces, When you attach, or inherit, a port profile to an interface or range of interfaces, the system applies all the commands in that port profile to the interfaces. Additionally, you can have one port profile inherit the settings from another port profile. Inheriting another port profile allows the initial port profile to assume all of the commands of the second, inherited, port profile that do not conflict with the initial port profile. Four levels of inheritance are supported. The same port profile can be inherited by any number of port profiles. The system applies the commands inherited by the interface or range of interfaces according to the following guidelines: • Commands that you enter under the interface mode take precedence over the port profile's commands if there is a conflict. However, the port profile retains that command in the port profile. • The port profile's commands take precedence over the default commands on the interface, unless the port-profile command is explicitly overridden by the default command. • When a range of interfaces inherits a second port profile, the commands of the initial port profile override the commands of the second port profile if there is a conflict. • After you inherit a port profile onto an interface or range of interfaces, you can override individual configuration values by enter the new value at the interface configuration level. If you remove the individual configuration values at the interface configuration level, the interface uses the values in the port profile again. • There are no default configurations associated with a port profile. A subset of commands are available under the port-profile configuration mode, depending on which interface type you specify. Note You cannot use port profiles with Session Manager. See the Cisco Nexus 7000 Series NX-OS System Management Configuration Guide, Release 5.x, for information about Session Manager. To apply the port-profile configurations to the interfaces, you must enable the specific port profile. You can configure and inherit a port profile onto a range of interfaces prior to enabling the port profile; you would then enable that port profile for the configurations to take effect on the specified interfaces. If you inherit one or more port profiles onto an original port profile, only the last inherited port profile must be enabled; the system assumes that the underlying port profiles are enabled. When you remove a port profile from a range of interfaces, the system undoes the configuration from the interfaces first and then removes the port-profile link itself. Also, when you remove a port profile, the system checks the interface configuration and either skips the port-profile commands that have been overridden by directly entered interface commands or returns the command to the default value. If you want to delete a port profile that has been inherited by other port profiles, you must remove the inheritance before you can delete the port profile. You can also choose a subset of interfaces from which to remove a port profile from among that group of interfaces that you originally applied the profile. For example, if you configured a port profile and configured ten interfaces to inherit that port profile, you can remove the port profile from just some of the specified ten interfaces. The port profile will continue to operate on the remaining interfaces to which it is applied. OL-23435-03 Cisco Nexus 7000 Series NX-OS Interfaces Configuration Guide, Release 5.x 2-11
