While I was upgrading NAM 2 from ver 3.6 to 4.1 I found that the connection is (Flapping) after the upgrade, then I found the following error on the core. (The NAM module is restarting)
000947: 12w1d: %SNMP-5-MODULETRAP: Module 2 [Down] Trap
000948: 12w1d: %OIR-SP-3-PWRCYCLE: Card in module 2, is being power-cycled 'off (Module not responding to Keep Alive polling)'
000949: 12w1d: %C6KPWR-SP-4-DISABLED: power to module in slot 2 set off (Module not responding to Keep Alive polling)
After checking the error meaning, I have found that the workaround is to restart the module many times!!
But the problem never solved, the problem only is resolved if I restarted the NAM in the (cf:1) mode, otherwise the module keeps restarting.
The following are the output of the show ver:
[email protected]# show ver
NAM application image version: 3.6(1a)
Maintenance image version: 2.1(3)
NAM Daughter Card Micro code version: 18.104.22.168 (NAM)
BIOS Version: 4.0-Rel 6.0.4
No patches are installed on this system.
And the Version I'm upgrading to is (the same as NAM1):
Could anyone help to resolve this problem?
