Configuring RADIUS Network Elements
A network element is a load-balanced group of RADIUS servers providing policy management for TDF subscribers.
Before you configure a network element, you must do the following:
Configure the RADIUS servers that are to be part of the network element.
To configure a network element:
- Specify a name for the network element.
[edit access radius] user@host# set network-elements name
- Specify the RADIUS servers that make up the network element.
[edit access radius network-elements name] user@host# set server name
- Assign each server in the network element a priority from
1 through 16 (1 is the highest priority). You can have multiple servers
with the same priority in a network element. All access requests are
load balanced among the highest priority servers. If all the servers
with the highest priority in the network element fail, then requests
are load balanced among servers with the next highest priority level.
[edit access radius network-elements name server name] user@host# set priority priority
- Configure the maximum number of requests that can be queued
to the network element. When the pending-request queue is full, any
additional requests are dropped.
[edit access radius network-elements name] user@host# set maximum-pending-reqs-limit number
- Configure the pending-request queue high watermark for
the network element. This is a percentage of the maximum number of
requests that can be queued to the network element, which is configured
in the
maximum-pending-reqs-limit numberstatement. When the queue size reaches the high watermark, aflow control onmessage is generated.[edit access radius network-elements name] user@host# set pending-queue-watermark watermark
- Configure the pending-request queue low watermark for
the network element. This is a percentage of the maximum size of the
pending-request queue, which is configured in the
maximum-pending-reqs-limit watermarkstatement. When the number of pending requests drops below this low watermark value after having exceeded the high watermark, aflow control offmessage is generated.[edit access radius network-elements name] user@host# set pending-queue-watermark-abate abate-watermark
