Configuring RADIUS Server Options for Subscriber Access

You can specify options that the router or switch uses when communicating with RADIUS authentication and accounting servers for subscriber access.

To configure RADIUS authentication and accounting server options:

1. Specify that you want to configure RADIUS.
   [edit access profile isp-bos-metro-fiber-basic]user@host# edit radius
2. Specify that you want to configure RADIUS options.
   [edit access profile isp-bos-metro-fiber-basic radius]user@host# edit options
3. (Optional) Configure the method the router or switch uses to access RADIUS accounting servers.
   [edit access profile isp-bos-metro-fiber-basic radius options]user@host# set client-accounting-algorithm round-robin
4. (Optional) Configure the method the router or switch uses to access RADIUS authentication servers.
   [edit access profile isp-bos-metro-fiber-basic radius options]user@host# set client-authentication-algorithm round-robin
5. (Optional) Configure the format the router or switch uses to identify the accounting session.
   [edit access profile isp-bos-metro-fiber-basic radius options]user@host# set accounting-session-id-format decimal
6. (Optional) Configure the router or switch to use a port type of virtual to authenticate clients.
   [edit access profile isp-bos-metro-fiber-basic radius options]user@host# set ethernet-port-type-virtual
7. (Optional) Specify the information that is included in or omitted from the interface description that the router or switch passes to RADIUS for inclusion in RADIUS attribute 87 (NAS-Port-Id).
   [edit access profile isp-bos-metro-fiber-basic radius options]user@host# set interface-description-format adapter
8. (Optional) Configure the value for the client RADIUS attribute 32 (NAS-Identifier), which is used for authentication and accounting requests.
   [edit access profile isp-bos-metro-fiber-basic radius options]user@host# set nas-identifier 56
9. (Optional) Configure the RADIUS client to use the extended format for RADIUS attribute 5 (NAS-Port) and specify the width of the fields in the NAS-Port attribute.
   [edit access profile isp-bos-metro-fiber-basic radius options]user@host# set nas-port-extended-format 16
10. (Optional) Configure the number of seconds that the router or switch waits after a server has become unreachable.
    [edit access profile isp-bos-metro-fiber-basic radius options]user@host# set revert-interval port-width 1200
11. (Optional) Specify that RADIUS attribute 5 (NAS-Port) includes the S-VLAN ID, in addition to the VLAN ID, for subscribers on Ethernet interfaces.
    [edit access profile isp-bos-metro-fiber-basic radius options]user@host# set vlan-nas-port-stacked-format
