Symptom When you click the Test button in the Set up > Switch Parameters menu window, the popup
window indicates that both the SNMP read and write to the switch failed.
Possible Cause Verify that the SNMP read-write community string is the same as the SNMP
read-write community string defined for the switch.
Note The password is case sensitive.
Recommended Action If the community string is correct and the test still fails, check that the switch
has enabled the IP permit list as follows:
Step 1 Log in to the switch in enable mode.
Step 2 Enter the show IP permit command.
If the IP permit list is enabled, make sure that the NAM internal address is added to the IP permit list.
The NAM address is 127.0.0.X, where X is the NAM module number multiplied by 10 plus 1. For
example, if the NAM is at module 4, then its address should be 127.0.0.41.
After you determine the NAM internal IP address, go to Step 3.
Step 3 Enter the set IP permit NAM-address SNMP command.
Symptom When a NAM is running in a switch with Catalyst operating system software, the NAM may
be shown as unreachable when you use the ping command or the NAM Traffic Analyzer application.
Possible Cause The NAM IP address and the IP address of the switch (interface sc0) are not in the
same subnet. This problem can occur if you change the switch IP address and the NAM VLAN
assignment. The NAM automatically synchronizes its VLAN assignment to the same VLAN in
which the switch (interface sc0) resides. When this occurs, the NAM IP address resides on a
different subnet from the VLAN assigned to the NAM. The router then drops any packet destined to
the NAM IP address. You cannot add a static route to the router because of route overlap caused by
improper VLAN assignments and subnetting.
Recommended Action Make sure that the NAM IP address and the switch are in the same subnet and
in the same VLAN.
