css load balancing udp service

[mike]

Hi, There:

If I need to load balance some udp application with use udp port, could I just monitor keepalive udp port and with flow-state (port#) flow-enable?

thx

the flow-enable is for particular udp ports for which we disabled flow.

When flow is disable, the CSS does per packet loadbalancing instead of per flow.

I'm not sure what kind of monitoring you expect with this command.

Also, udp keepalive does not exist as there is no default response. It depends on the protocol.

so based on this sample configuration, it still use icmp for monitoring not udp port?

I just want to monitor that destination port, if that port is closed, should destination host send out icmp destination unreachable, will CSS receive icmp destination unreachable, and take that host out of service?

Thx,

[Gilles Dufour]

no - there is no udp keepalive.

You could create a script for your application that will send udp data and wait for a udp response [not icmp].

the sample config you referenced has no keepalive config, so the service uses the default icmp keepalive.
