radius-server algorithm master-backup

Function

The radius-server algorithm master-backup command sets the algorithm of a RADIUS server.

The undo radius-server algorithm master-backup command restores the default setting.

By default, the RADIUS server adopts the active/standby algorithm and the authentication server is preferentially used as the accounting server.

Format

radius-server algorithm master-backup { strict | sequence } ^*

undo radius-server algorithm master-backup { strict | sequence } ^*

Parameters

Parameter	Description	Value
strict	Indicates that the accounting server is selected based on the configured algorithm. The master accounting server is preferentially selected, irrelevant to the authentication server.	-
sequence	If sequence is configured, the system selects a server in the sequence in which the servers are configured.	-
master-backup	Indicates the active/standby algorithm. Only the RADIUS authentication server or accounting server configured first is the active server.	-

Parameter

Description

Value

strict

Indicates that the accounting server is selected based on the configured algorithm. The master accounting server is preferentially selected, irrelevant to the authentication server.

sequence

If sequence is configured, the system selects a server in the sequence in which the servers are configured.

master-backup

Indicates the active/standby algorithm. Only the RADIUS authentication server or accounting server configured first is the active server.

Usage Guidelines

Usage Scenario

The radius-server algorithm command takes effect only for all authentication servers and accounting serves in a specified RADIUS server.

When the active/standby algorithm is used, the second configured RADIUS server becomes the master server if the master RADIUS server is deleted.

A RADIUS server group supports a maximum of sixteen authentication servers and sixteen accounting servers.

Example

# Set the active/standby algorithm as the algorithm of the RADIUS server.
