How to configure Port Profiles in Nexus switches?

Port Profiles is a feature of Nexus switches, which allow a template of configuration to apply to a group of ports. This is similar to interface macros in Catalyst IOS. Unlike Catalyst IOS macros, NX-OS port-profiles are event driven, meaning IOS macros apply only once during initial configuration, but P0rt profiles immediately re-apply any time a change is made to the profile. You can read more detail from cisco official site.

In this lesson, we will learn, how to configure Port Profiles in Nexus switches?

Prerequisites:

Configuration:

To configure, we have to go through few steps. These are –

Create the profile:
In this step, we will create a pofiles and name it “OurPortProfiles”. We are going to create our profile based on ethernet, however we have option to create it on port-channel and SVI.

Command:
port-profile type [ethernet | interface-vlan | port-channel] [name]

Example:
N7K-01(config)# port-profile type ethernet OurPortProfiles

Apply configuration to profile:
Here we will specify the configure. Later, if needed we can modify it.

Example:
N7K-01(config)# port-profile type ethernet OurPortProfiles
N7K-01(config-port-prof)# no shutdown
N7K-01(config-port-prof)# switchport mode access
N7K-01(config-port-prof)# switchport access vlan 10
N7K-01(config-port-prof)# spanning-tree port type edge

Enable the profile
By default, port-profiles are disabled. We can verify it using “show port-profile” command.

N7K-01# show port-profile

SHOW PORT_PROFILE

port-profile OurPortProfiles
 type: Ethernet
 description:
 status: disabled
 max-ports: 16384
 inherit:
 config attributes:
  spanning-tree port type edge
  switchport
  switchport access vlan 10
  no shutdown
 evaluated config attributes:
  spanning-tree port type edge
  switchport
  switchport access vlan 10
  no shutdown
 assigned interfaces:

Let’s enable it and then verify.

N7K-01(config)# port-profile type ethernet OurPortProfiles
N7K-01(config-port-prof)# state enabled

N7K-01# show port-profile

SHOW PORT_PROFILE

port-profile OurPortProfiles
 type: Ethernet
 description:
 status: enabled
 max-ports: 16384
 inherit:
 config attributes:
  spanning-tree port type edge
  switchport
  switchport access vlan 10
  no shutdown
 evaluated config attributes:
  spanning-tree port type edge
  switchport
  switchport access vlan 10
  no shutdown
 assigned interfaces:

Assign profile to interface:
Now you have to assign “OurPortProfiles” profile into the interface using “inherit” command. We are assigning it on interface e1/1 to e1/10.

Command:
inherit port-profile [name]

Example:
N7K-01(config)# interface e1/1-10
N7K-01(config-if-range)# inherit port-profile OurPortProfiles

Verification:

Command:
show port-profile
show run interface [interface range]
show port-profile expand-interface name [name]
