CSS Multiple modules sharing CPU resources.

Unanswered Question

Good afternoon,

Maybe I miss understood, but I thought that If I had multiple modules wether it be a SCM or IOM module that the load would be spread across multiple modules?

If I keep checking the cpu resources, I see that only the SCM module has any CPU load on them.

RESNXLB01_C0302# sh system-resources cpu_summary

Chassis CPU Utilizations

Name Slot Sub CPU%

----------------------------------

CSS5-SCM-2GE F0 1 1 33%

CSS5-IOM-2GE E0 2 1 0%

RESNXLB01_C0302# sh system-resources cpu_summary

Chassis CPU Utilizations

Name Slot Sub CPU%

----------------------------------

CSS5-SCM-2GE F0 1 1 43%

CSS5-IOM-2GE E0 2 1 0%

RESNXLB01_C0302# sh system-resources cpu_summary

Chassis CPU Utilizations

Name Slot Sub CPU%

----------------------------------

CSS5-SCM-2GE F0 1 1 29%

CSS5-IOM-2GE E0 2 1 0%

the traffic load is shared between the modules but only the SCM does all the maintenance function like CLI, Telnet, Routing Table,...

If your traffic is very low - less than 1% cpu required, you don't see any activity on the other module.

Do a 'flow stat' and verify your traffic rate on each module - FCB per seconds.

Rich,

yes, the SCM is the only one managing the scripts and keepalives.

Gilles.

So is there any other way to accomplish the following service without utilizing a script? At a minimum presenting the web server with the host headder tag? Could something be done with a global keepalive?

service Marketplace-2

ip address x.x.x.x

keepalive port 80

redundant-index 8741

keepalive frequency 30

keepalive type script ap-kal-httptag "Marketplace2.company.com /keepalive/lb.htm Marketplace2"

active

Thx
