Configuring Probes for Health Monitoring

 

Command

Purpose

Step 3

 

 

Router(config-slb-probe-http)# expect

Configure a status code to expect from the HTTP probe.

 

status min-number [max-number]

You can configure multiple status ranges by entering one

 

 

expect command at a time1.

 

 

min-number—If you do not specify a max-number, this

 

 

number is taken as a single status code. If you specify a

 

 

max-number, this number is taken as the minimum status

 

 

code of a range.

 

 

max-number—The maximum status code in a range. The

 

 

default range is 0–999. (Any response from the server is

 

 

considered valid.)

 

 

Note If no maximum is specified, this command takes

 

 

a single number (min-number). If you specify

 

 

both a min-number and a max-number, it takes

 

 

the range of numbers.

Step 4

 

 

Router(config-slb-probe-http)# header

Configure a header field for the HTTP probe. Multiple

 

field-name [field-value]

header fields may be specified1.

Step 5

Router(config-slb-probe-http)# request

Configure the request method used by an HTTP probe1:

 

[method [get head]] [url path]

• get—Directs the HTTP get request method directs

 

 

 

 

the server to get this page

 

 

• head—Directs the HTTP head request method

 

 

directs the server to get only the header for this page

 

 

• url—A character string of up to 1275 characters

 

 

specifies the URL path; the default path is “/”

 

 

Note The CSM supports only the get and head request

 

 

methods; it does not support the post and other

 

 

methods. The default method is head.

 

 

 

1. The no form of this command restores the defaults.

ICMP Probe

An ICMP probe sends an ICMP echo (for example, ping) to the real server. The ip slb probe icmp command enters the ICMP probe configuration mode. All the common ip slb probe commands are supported except open, which is ignored.

 

Command

Purpose

Step 1

 

 

Router(config)# ip slb probe probe-nameicmp

Configure an ICMP probe and enter the ICMP

 

 

probe submode1.

Step 2

 

 

Router(config-slb-probe-icmp)# [failed

Configure the intervals to wait between probes

 

interval retries receive]

of a failed server and between probes. Also,

 

 

specify the time to make a TCP connection, to

 

 

receive a reply from the server, and to limit the

 

 

number of retries before considering the real

 

 

server as failed.

 

 

 

1.The no form of this command restores the defaults.
