Usage Scenario
The EDSG service allows a device to obtain an EDSG service policy from the local configuration, RADIUS server, or their combination.
Prerequisites
A RADIUS server group has been configured if an EDSG service policy needs to be obtained from a RADIUS server.
Configuration Impact
After the
service-policy download command is run on a device, the device obtains an EDSG service policy in any of the following modes:
- Local: A service name is used as an index to obtain an EDSG service policy from the local configuration.
- RADIUS: A service name is used as a user name and authentication packets are used to obtain an EDSG service policy from a RADIUS server. The obtained EDSG service policy is cached to the local device and will not be deleted if it is referenced by any service instance. The EDSG service policy does not need to be repeatedly obtained.
- First from the local configuration and then from an RADIUS server: A device first attempts to obtain an EDSG service policy from the local configuration. If no EDSG service policy is locally configured, the device obtains an EDSG service policy from an RADIUS server.
- First from an RADIUS server and then from the local configuration: A device first attempts to obtain an EDSG service policy from an RADIUS server. If the RADIUS server does not respond after expiration, the device obtains an EDSG service policy from the local configuration.
Precautions
A password is required if you specify the RADIUS mode.
