CSS - "weight 0" for aca or weightedrr ONLY?

[gzkjgs]

I understand from the documentation that the "weight" command in a service only affects rules with "balance aca" or "balance weightedrr". Does this also extend to the use of "weight 0" to perform a graceful shutdown of a service? In other words, if my content rule is roundrobin, will it still stop sending new connectons to the service that has the "weight 0" configured?

The weight is a concept that applies to round robin (roundrobin) or weighted round robin (weightedrr) only.

ACA is a load balance algorithm that prefers servers with better response times, over

servers with worse response times. The CSS would use normalized average response times

from synchronize/start (SYN) to finish (FIN) of the TCP connections between clients and

servers to determine a load value for each server. As the load value increases for a

server, the less requests ACA sends to it.

You can assign a weight on the content rules with the add service page1 weight

command or assign it on the service configuration with weight

. If both are specified the one configured on the content rule takes

precedence.

The weight value is an integer from 0 to 10. 1 is the default and 0 would put the service is graceful shutdown.

If you configure service a with a value 1 and service b with a value of 3, it means

that for every connection sent to service a, 3 connections would be sent to b.

Configure the weight on the content rule if you are using weightedrr.
