Cant remove outdated "radius-server host x.x.x.x" from config.

Good day everybody!

 

First things first.

Platform : Nexus C92160YC-X

Software version : 7.0(3)I7(5)

 

I am configuring our data-center switches with ipv6 and removing ipv4.

 

The problem is that i cant remove the old radius-server host configurations.

no radius-server host {ipv4-address} key 7 "removed" auth-port XXXX authentication
As this operation causes both accounting and authentication to be disabled for the server, it is denied. 

When i logg into the eqipment the radius-prosess starts on the top of the list where the old ipv4 configurations are.

radius-server host {ipv4-address} key 7 "removed" auth-port XXX authentication 
radius-server host {ipv4-address} key 7 "removed" auth-port XXX authentication 
radius-server host {ipv6-address} key 7 "removed" auth-port XXXX authentication 
radius-server host {ipv6-address} key 7 "removed" auth-port XXXX authentication 

Making the login process time consuming. I worked around that problem with "dead timers".

 

In my effort to remove the old ipv4 configurations i have :

- tried different variations like suggest here 

- search for solution on community.cisco.com, cisco.com, and all over google.

- Looked at several different configurations guides for nexus 9200 and 9300.

 

Any insights that help me removing the old ipv4 configurations are much appreciated.

It worked.

 

I still got warning. But the config is removed now.

 

no radius-server host {ipv4-address}
Radius command failed to apply
