enable Auth-Type := Local, User-Password == "pass5678" Service-Type = Administrative-User The values for the Service-Type attribute are as follows: • NAS-Prompt-User indicates the user should be provided a command prompt on the switch, which is acting as the Network Access Server (NAS), from which nonprivileged commands can be executed. • Administrative-User indicates the user should be granted access to the administrative interface to the NAS, from which privileged commands can be executed. What are RADIUS Server Groups? The RADIUS client on each PowerConnect 7000 Series switch supports multiple, named RADIUS servers. When one or more configured authentication servers that share the same RADIUS server name, they form a group. Named groups can help provide redundancy. If you configure multiple RADIUS servers with the same RADIUS Server Name, designate one server as the primary and the other(s) as the backup server(s). The switch attempts to use the primary server first, and if the primary server does not respond, the switch attempts to use one of the backup servers with the same RADIUS Server Name. A priority value can be configured to determine which backup server to contact. How Does the Switch Determine Which RADIUS Server to Contact? If the primary server in the named group is unavailable, the switch marks the backup server with the highest priority (or the first available RADIUS server in the group, if all priorities are equal) as the current server. The switch attempts to contact the primary server every five minutes, which is not a configurable value, and if the primary RADIUS server is available, it will resume its role as the current RADIUS server. The RADIUS Dead Time is a configurable number of minutes the switch should consider an unavailable RADIUS server as dead. The switch will not attempt to contact the RADIUS server until the dead time has expired. 176 Controlling Management Access
