Diagnostics and Troubleshooting

No SNMP Connection Established

PROBLEM: Cannot establish an SNMP session/connection.

ACTION: 1. Try to ping the MCC card and/or DSL card from the management system.

2.If you cannot, check to see that you have entered an IP address and subnet mask (see Who Am I screen in Chapter 3).

3.If there is an IP address, then check the routing tables in the MCC card and DSL card.

4.Check to see if the community string is correct.

5.If IP Address Security is enabled, check to see that Network Management's IP address has been entered correctly in the MCC card's and DSL card's permission list and that it has proper access.

6.Check to see if you have properly configured the SNMP parameters (see Monitoring Network Protocol (B-D) in Chapter 7, especially SNMP Security: Configuration SNMP (A-F) in Chapter 6).

Filters Not Working

PROBLEM: Filters are not working properly.

ACTION: 1. Check to see that filters have been configured properly (see Configuration Interfaces (A-C) in Chapters 5 and 6).

2.Check to see if there is a conflict with the order of the filter tests. They should perform in the following order: Port-to-Port (PTOP), Host-to-Port (HTOP), Host-to-Host (HTOH), Protocol Type (PROTOCOL), Bit Filtering.
