Usage Guidelines

 

This command is not used for any non-TCP probes, such as ICMP or DNS.

 

 

 

 

 

 

 

Note

 

There are two different timeout values: open and receive. The open timeout specifies how many seconds

 

 

 

 

to wait for the connection to open (that is, how many seconds to wait for SYN ACK after sending SYN).

 

 

 

 

The receive timeout specifies how many seconds to wait for data to be received (that is, how many

 

 

 

 

seconds to wait for an HTTP reply after sending a GET/HHEAD request). Because TCP probes close as

 

 

 

 

soon as they open without sending any data, the receive timeout is not used.

 

 

 

 

 

 

 

 

 

 

 

 

 

Examples

 

This example shows how to configure a time to wait for a TCP connection of 5 seconds:

 

 

 

 

Cat6k-2(config-slb-probe-http)# open 5

 

 

 

 

probe
