I don't know why did incidented log.

pls answer the question.

thanks.

There is broadcast in your network, talk to your data guys so they control that in that VLAN, that disables the ethernet port by security.

that disables the ethernet port by security

Just disable broadcast reception, not ethernet port...

If you have two CPU and both connected to the LAN - forbid On-board ethernet on CPU with jumper (f.e. X900 for CPU6).

I agree with the above Guru, as believe me, I have experienced this and it is network all of the time. If your incident is occurring frequently and you use Appliance servers instead of CPU6/7, then the issue you get is that the system will start to slow down and IP phones will reboot randomly, due to the fact it cannot get a response from the system (due to the slowdown of the network)

I had a site whereby there was a machine infected with a virus and was sending out 1000 requests a minute to all devices in the network, the system swapped/basculed itself many times and cut a lot of call centre calls off. As soon as I unplugged the machine concerned (after running wireshark I found the MAC and IP address of who it was, then I run a Ip scanner program to find the machine name) unpluggfed the ethernet from the machine and all was fixed.

Be aware that if there are a lot of 4401 errors and the network is slow, then you will experience bigger problems.

Hi Hello, Could you be more specific? Please.

CPU board has on-board Ethernet switch. One Ethernet port usually connected to CBRMA (for external connection) and second (on-board, embedded) for inter CPU connection via backplane.
And you can use (in CPU duplicated case) two type connection:
1) One external connection (Eth0 or 1 from CBRMA). Access to second CPU via embedded Ethernet. Exist one problem - during CPU restart (which Ethernet used for external connection) you lost access to system.
2) Two external connection (Eth0 AND Eth1 from CBRMA). In this case you need to forbid second Ethernet port on CPU (for loop disable - external switch-CPU1-CPU2-external switch).

jumper X900 used for enable (case 1) or disable (case 2) on-board/embedded/interCPU Ethernet access.

I had this issue recently. The cause was associated with ethernet switch port configuration. The network switch had the ethernet port configured as autonegotiated instead of 100M Full as we had defined in the oXE board (in this case, the incident was related to INTIP boards of an IPMG). I think because network switch try to negotiate there are sent some broadcast (?) and then the alarm rose .
