Hi,


At one of our sites we regularly have problems that the access-points can't connect to the radius server in the central site. My collegue configured the aaa dead-time but this gave no difference.


This is the error message :


10:02:14 bstonw53 RADIUS-4-RADIUS_DEAD: RADIUS server 10.161.5.22:1812,1813 is not responding.

10:02:14 bstonw53 RADIUS-4-RADIUS_ALIVE: RADIUS server 10.161.5.22:1812,1813 has returned.


Within a second he claims that the radius server is dead en alive again .


We are pretty sure that the line is under heavy load but tried to resolve it with the aaa dead-time configuration.



aaa group server radius rad_eap

aaa group server radius rad_mac

aaa group server radius rad_acct

aaa group server radius rad_admin

aaa group server radius rad_pmip

aaa group server radius dummy

ip radius source-interface BVI1

radius-server attribute 32 include-in-access-req format %h

radius-server dead-criteria tries 5

radius-server host 10.161.5.22 auth-port 1812 acct-port 1813 key xxx

radius-server host 10.161.5.21 auth-port 1812 acct-port 1813 key xxx

radius-server retransmit 20

radius-server timeout 20

radius-server vsa send accounting


Can somebody help me with the radius configuration ?
