Troubleshooting Network Protocol Problems
This chapter provides information on resolving problems that may occur when working with various network protocols.
This chapter comprises the following topics:
5.1 Working With CMIP
This section describes the following:
- Configuring CMIP Agents
- CMIP MPA Does Not Work
- MIS-to-MIS Communication
- Remote MIS Problems
- CMIP PMI Events Errors
5.1.1 Configuring CMIP Agents
Problem: You do not know how to configure a CMIP agent.
Solution: If the agent has not been added as an object, use the Network Views -> Actions -> Create -> Object window to create it. If the agent object already exists and you want to modify it, use the Network Views -> Object Properties window. You can also invoke these windows from the command line by typing the command:
/opt/SUNWconn/em/bin/em_oct -cmipSee Also: Managing Your Network guide.
5.1.2 CMIP MPA Does Not Work
Problem: The CMIP MPA does not start.
Solution: Solstice EM's daemons start when you execute the command:
/etc/rc2.d/s98cmipmpa startSee Also: Installation Guide.
5.1.3 MIS-to-MIS Communication
Problem: You do not know how to set up communications from one MIS to another.
- If you only want to view event information on multiple MISs, you can access the second MIS directly from the Log Entries -> Properties window.
- If you want to forward events to another MIS, you have to define the Event Forwarding Discriminator (EFD) as defined in em_oct -cmip (field: entity name) to enable this capability.
See Also: Management Information Server Guide and the Managing Your Network guide.
5.1.4 Remote MIS Problems
Problem: You are unable to view any of the information on a remote MIS.
- MIS-MIS communication is not configured correctly. Use MIS Connections to configure MIS-MIS communication.
- The remote MIS server is down.
- The network connection between your current MIS and the remote MIS is broken.
See Also: Management Information Server Guide and the Managing Your Network guide.
5.1.5 CMIP PMI Events Errors
Problem: You receive an error in special processing of PMI events and you cannot find module CMIP-1.
Solutions: Try these procedures to fix the problem.
- If two CMIP MPAs are running using the same port number. Reconfigure them.
- Ensure the CMIP stack is started.
5.2 Working With SNMP
5.2.1 Cannot Delete Entry From MIB
Problem: Attempts to delete an entry from an SNMP MIB either through the SNMP Data tool or from within a user-developed code function does not work.
Solution: Perform the following setup steps to enable Solstice EM to delete entries from SNMP MIBs.
1. Compile the MIB to its GDMO and ASN.1 files using the Load Data Definitions tool in Solstice EM's Administration Tools window. If the MIB has already been compiled, ignore this step.2. Consult the text definitions of the table entries in the MIB and find the attribute used for deletion of the entry and its value.3. In the corresponding GDMO file for the entry's name bindings, modify the following values:
CREATEDELETEATT
CREATEDELETEVALUE
Look at the following example for MIB-II. In rfc1213.mib, you have the following:
ipNetToMediaType OBJECT-TYPE
SYNTAX INTEGER {
other(1),
invalid(2),
dynamic(3),
static(4)
}In rfc1213.gdmo, you might have something like this:
MULTIPLEINSTANCES
INDEX
ipNetToMediaIfIndex,
ipNetToMedia NetAddress;
CREATEDLETEATT ipNetToMediaType
CREATEDELETEVALUE 2
