Version Description
7.5.1.0 Introduced on the C-Series.
pre-6.2.1.0 Introduced on the E-Series.
Usage
Information
To configure any number of RADIUS server hosts for each server host that is configured, use this
command. Dell EMC Networking OS searches for the RADIUS hosts in the order they are configured in
the software.
The global default values for the timeout, retransmit, and key optional parameters are applied,
unless those values are specified in the radius-server host or other commands. To return to
the global default values, if you configure the timeout, retransmit, or key values, include those
keywords when using the no radius-server host command syntax.
You can use duplicate host names or IP addresses among RADIUS groups. However, you cannot use
duplicate host names or IP addresses within the same RADIUS group. If a VRF is not configured on the
RADIUS group, then servers configured in the group are considered to be on the default VRF. RADIUS
servers that are configured in the CONFIGURATION mode are also considered to be on the default VRF.
You must configure the RADIUS group explicitly with the aaa radius group command in order for the
AAA servers to use the group of RADIUS servers. The 802.1x servers use the group of RADIUS servers
based on the VRF where the 802.1x request is received. As a result, it is possible that both globally
configured RADIUS servers as well as the group-configured RADIUS servers (without VRF or default
VRF) are used for processing the 802.1x requests that are received at the default VRF. The order in
which the RADIUS servers are tried depends on the order in which the RADIUS servers are configured.
The RADIUS accounting port acct-port port-number is configurable.
Example
DellEMC(config)#radius-server host 192.100.0.12
Force all logged-in users to re-authenticate (y/n)?
DellEMC(config)#no radius-server host 192.100.0.12
Force all logged-in users to re-authenticate (y/n)?

Syntax
radius-server vrf vrf-name [source-interface interface]
To delete the association between a RADIUS server group and a VRF and source interface, use the no
radius-server vrf vrf-name [source-interface interface] command.
Parameters
vrf vrf-name Enter the keyword vrf and then the name of the VRF to associate a RADIUS
server group with that VRF.

TenGigabitEthernet then the slot/port/subport[/subport] information.
● For a 40-Gigabit Ethernet interface, enter the keyword fortyGigE then the
slot/port information.
