Guidelines for Configuring RADIUS NAS-Port Options for Subscriber Access per Physical Interface, VLAN, or Stacked VLAN
The following guidelines apply when you configure the NAS-Port-Type attribute and the extended format for the NAS-Port attribute on a per-VLAN, per-stacked VLAN, or per-physical interface basis:
- You can create a maximum of 16 NAS-Port options definitions per physical interface. Each definition can include either a maximum of 32 VLAN ranges or a maximum of 32 stacked VLAN ranges, but cannot include a combination of VLAN ranges and stacked VLAN ranges.
- Configuring the NAS-Port-Type attribute and NAS-Port extended format on a per-VLAN, per-stacked VLAN, or per-physical interface basis overrides the global settings for these attributes configured in an access profile.
- If the NAS-Port-Type attribute and the NAS-Port extended format are not configured on a per-VLAN basis (in a 1:1 access model) or on a per-stacked VLAN basis (in an N:1 access model), the router uses the global settings configured for these attributes in an access profile for all RADIUS request messages.
