Access FEX Interface Profile

FEX Interface Profiles can either be auto-generated (one per FEX) by providing a naming convention, or can be system-generated (one per FEX), or can be defined explicitly. In case of auto-generated profiles the following placeholders can be used when defining the naming convention:

\\g<id>: gets replaced by the respective leaf node ID
\\g<name>: gets replaced by the respective leaf hostname
\\g<fex>: gets replaced by the respective FEX ID

Examples

Auto-generated profiles:

apic:
  auto_generate_access_leaf_switch_interface_profiles: true
  access_policies:
    fex_profile_name: "LEAF\\g<id>-FEX\\g<fex>"
  interface_policies:
    nodes:
      - id: 101
        fexes:
          - id: 101

System-generated profiles:

apic:
  new_interface_configuration: true
  interface_policies:
    nodes:
      - id: 101
        fexes:
          - id: 101

Example-1: This configuration explicitly creates a FEX interface profile named LEAF101-FEX101, with a selector SEL1 that applies the 10G-SERVER policy group to a port block BLOCK1 starting at port 1.

apic:
  access_policies:
    fex_interface_profiles:
      - name: LEAF101-FEX101
        selectors:
          - name: SEL1
            policy_group: 10G-SERVER
            port_blocks:
              - name: BLOCK1
                description: Server ABC
                from_port: 1

Example-2: This is another example for a FEX Interface Profile, along with a clear description of each value.

fex_interface_profiles: List of FEX interface profiles to define explicitly.
selectors: List of selectors for this profile.
policy_group: The policy group to associate with this selector (e.g., 20G-APP-SERVERS).
port_blocks: List of port blocks under this selector.
from_port and to_port: Starting port number in the block (e.g., 1) and ending port number in the block (e.g., 8).

apic:
  access_policies:
    fex_interface_profiles:
      - name: LEAF102-FEX201
        selectors:
          - name: FEX201-SEL
            policy_group: 20G-APP-SERVERS
            port_blocks:
              - name: APP-BLOCK
                description: Application Servers Block
                from_port: 1
                to_port: 8
