3300 looses network connec tion after 15 minutes

[jimcricket]

MIPS reset seems to restore service temporarily.

Clearing the ARP Table on the network router also restores service.

whats the solution??

If it is an early MXe Chassis I would say it will need replacing. We've had 3 with this problem in the last few years.

MN446465 - MXE II L2 dies, using mips_reset recovers L2 temporarily ,after a while L2 stops responding
Problem Symptoms:-
Controller loses all IP connectivity.
IP sets and ESM connection lost. Can´t ping controller.
The L2 switch would give the perception that the System had failed.
If you are monitoring the RTC, you may see the following logs just prior to not being able to ping controller are as follows:

!!! WARNING: System restart may occur !!!

_Upgrade_Cfe: BCM image /sysro/mxe_bcm_cfe.bin
_Upgrade_Cfe: comparing 223064 bytes in BCM CFE images...
_Upgrade_Cfe: BCM CFE images same - no upgrade required 


Problem Workaround:-
So here´s the command to automatically do a periodic reset of the MIPS/L2 switch every 15 minutes:

period 900,mips_reset

Note the timer is in seconds.
Feel free to increase the reset timer.
