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
LD
===
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
