ANTA catalog for VLAN tests

VerifyVlanInternalPolicy

Verifies if the VLAN internal allocation policy is ascending or descending and if the VLANs are within the specified range.

Expected Results
  • Success: The test will pass if the VLAN internal allocation policy is either ascending or descending and the VLANs are within the specified range.
  • Failure: The test will fail if the VLAN internal allocation policy is neither ascending nor descending or the VLANs are outside the specified range.
Examples 
anta.tests.vlan:
  - VerifyVlanInternalPolicy:
      policy: ascending
      start_vlan_id: 1006
      end_vlan_id: 4094

Inputs

Name Type Description Default
policy Literal['ascending', 'descending']
The VLAN internal allocation policy. Supported values: ascending, descending.
-
start_vlan_id Vlan
The starting VLAN ID in the range.
-
end_vlan_id Vlan
The ending VLAN ID in the range.
