Chapter 4      Modifying IPM Components
    Setting SNMP Timeout and Retry Environment Variables
The following environment variables control SNMP timeouts and retries:
Using the default values, IPM waits 50 seconds before determining that an SNMP request cannot be 
completed—5 seconds for the initial timeout, followed by 3 retries of 10, 15, and 20 seconds each.
If excessive SNMP timeouts are a problem in your network, try slightly increasing the timeout and 
timeout increment values until the problem is eliminated.
To set new values for these variables, use one of the following procedures:
Setting SNMP Environment Variables in Solaris
To set SNMP environment variables in Solaris, use the following procedure:
Step 1
Make sure the IPM server is not running. You must set these environment variables while the IPM server 
is not running. To stop the IPM server, enter:
# cd /opt/CSCOipm/bin 
# ./ipm stop 
Step 2
On your IPM server, use a text editor to open the ipm.env file. In Solaris, the default directory for the 
ipm.env file is /opt/CSCOipm/etc.
Note
The default directory for installing IPM is /opt. If you installed IPM in a different directory, 
specify that directory instead of /opt.
Variable
Description
IPM_SNMP_TIMEOUT
Time in seconds for the IPM server to wait for a 
response. The valid range is 1 to 60 seconds. The 
default is 5 seconds.
IPM_SNMP_RETRIES
Number of times the IPM server tries again to send 
a request that has timed out while waiting for a 
response. The valid range is 1 to 5 retries. The 
default is 3 retries.
IPM_SNMP_TIMEOUT_
INCREMENT
Time in seconds to add to the current time-out value 
for subsequent retries. The valid range is 1 to 60 
seconds. The default is 5 seconds.
