Networking Domains
A fabric administrator creates domain policies that configure ports, protocols, VLAN pools, and encapsulation. These policies can be used exclusively by a single tenant, or shared. Once a fabric administrator configures domains in the ACI fabric, tenant administrators can associate tenant endpoint groups (EPGs) to domains.
The following networking domain profiles can be configured:
-
VMM domain profiles (
vmmDomP
) are required for virtual machine hypervisor integration. -
Physical domain profiles (
physDomP
) are typically used for bare metal server attachment and management access. -
Bridged outside network domain profiles (
l2extDomP
) are typically used to connect a bridged external network trunk switch to a leaf switch in the ACI fabric. -
Routed outside network domain profiles (
l3extDomP
) are used to connect a router to a leaf switch in the ACI fabric. -
Fibre Channel domain profiles (
fcDomP
) are used to connect Fibre Channel VLANs and VSANs.
A domain is configured to be associated with a VLAN pool. EPGs are then configured to use the VLANs associated with a domain.
Note |
EPG port and VLAN configurations must match those specified in the domain infrastructure configuration with which the EPG associates. If not, the APIC will raise a fault. When such a fault occurs, verify that the domain infrastructure configuration matches the EPG port and VLAN configurations. |
