IOS SLB RADIUS framed-IP sticky database

[irodi]

We have the follow configuration:

ip slb serverfarm MMS_BOX

nat server

failaction purge

probe MMS_PING

!

real 10.10.1.39

weight 100

faildetect numconns 3 numclients 1

inservice

!

real 10.20.1.201

weight 20

faildetect numconns 3 numclients 1

inservice

!

ip slb vserver MMS_GW_RADIUS

virtual 213.1.1.89 udp 1813 service radius

serverfarm MMS_BOX

delay radius framed-ip 30

sticky radius framed-ip group 1

idle radius request 5

idle radius framed-ip 3780

purge radius framed-ip acct on-off

purge radius framed-ip acct stop 8

replicate casa 192.168.1.82 192.168.1.83 11813

inservice standby hsrp_fw

!

ip slb vserver MMS_GW_TCP

virtual 213.1.1.89 tcp 0

serverfarm MMS_BOX

sticky radius framed-ip group 1

idle 1200

idle radius request 5

idle radius framed-ip 1200

inservice standby hsrp_fw

!

ip slb vserver MMS_GW_UDP

virtual 213.1.1.89 udp 0

serverfarm MMS_BOX

sticky radius framed-ip group 1

idle 300

idle radius request 5

idle radius framed-ip 1200

inservice standby hsrp_fw

!

What we see is that sometimes the not Radius flow does not use the sticky table and on the real with final .201 we see just only the not radius flow, without receiving the accounting packet.

Is this possible?

Thanks

To specify the minimum time IOS Server Load Balancing (IOS SLB) maintains connection information in the absence of packet activity, use the idle command in SLB virtual server configuration mode. To restore the default idle duration value, use the no form of this command.

idle [gtp imsi duration [query [max-queries]] | gtp request duration| ipmobile request duration| radius {request | framed-ip} duration]

no idle [gtp imsi duration [query [max-queries]] | gtp request duration| ipmobile request duration| radius {request | framed-ip} duration]

30 seconds for RADIUS entries in the IOS SLB session database.
