LD to CSS polling

Mike.Saban — Wed, 10 May 2006 20:07:12 GMT

Hi Guys

I have put in a solution where a CSS service is polling a mainframe on a specific port using a graceful shutdown using command

keepalive tcp-close fin. This is good and works ok.

However I have a number of questions. Further back in the network I have a Local Director with the reals set to the content rules VIP on the CSS, what I would like to occur is that if the service fails on the CSS, the LD will notice this and the real will go into a down state.

Here is the config - made up addresses

CSS

====

circuit VLAN2

description CSS-LD EXAMPLE

ip address 10.10.10.1 255.255.255.0

ip virtual-router 3 priority 105

ip redundant-vip 3 10.10.10.23

ip critical-service 3 VRRP_CRITICAL_SERVICE_SYC01A

service SERVICE1

ip address 20.20.20.201

protocol tcp

redundant-index 163

keepalive type tcp

keepalive port 8044

keepalive frequency 30

keepalive tcp-close fin

active

content SERVICE1-VIP

vip address 10.10.10.23

redundant-index 169

add service SERVICE1

protocol tcp

port 8044

active

===

virtual 30.30.30.30:8004:0:tcp is

predictor 30.30.30.30:8044:0:tcp roundrobin

real 10.10.10.23:8044:0:tcp is

name 10.10.10.23 CSS-VIP

bind 30.30.30.30:8044:0:tcp 10.10.10.23:8044:0:tcp

First problem is that if I suspend the service the content rule stays active, why doesnt this go down ?

Second, if I suspend the content rule, why does the LD still show the real as being up

Third, if I just bypass the CSS from the LD, can I poll the server with a graceful keepalive (FIN) rather than just a RST.

Many Thanks

Thanks for your response, although I'm not sure how the RME product guide will help me with this issue ?
