Event Logs information

Bo_Bo_Pai_Htet — Sun, 20 Jul 2014 09:29:00 GMT

Hi ,

I would like to know some Event Logs info from X440 Series Switch as below.
Could you please help me in detail what mean for and how to fix it properly?

1) Slot-1:Power usage exceeding threshold for slot 2
2) Slot-1:Port 2:24 Link Down
3) Slot-1:IPv4 multicast entry not added. Hardware L3 Table Full. ( Logged at most once per hour.)
4) Slo-1: Port 3:21 is delivering power
5) Slot-1: Internal Power Supply in slot 5 is disconnected
6) Slot-1:Slot-5 down , resetting all TCP connections to it
7) Slot-1:Module in Slot-5 is removed

Please kindly help me above Event Logs , some logs appeared frequently with unique port/slot numbers?

If you have Event logs reference documents , please kindly share us.

Thanks
Best Regards

Slo-1: Port 3:21 is delivering power

Description:The speci ed port is delivering power.
Remedy:No action required.

Slot-1:Power usage exceeding threshold for slot 2

Description:The power consumption used by Power-over-Ethernet devices is exceeding the system-wide threshold.
Remedy:Increase the amount of power available for the slot, or reduce the amount of power being used by the
Power-over-Ethernet devices.

Slot-1:IPv4 multicast entry not added. Hardware L3 Table Full. ( Logged at most once per hour.)

Description:IPv4 Multicast processing on speci ed slot logged a message of severity 'Warning'.

X440 switch has small L3 table. You can check if X440 switches are hitting the limitation or not. We could tweak the table depending upon the requirement. It would be nice if you can open TAC case to narrow down the issue ASAP.

2) Slot-1:Port 2:24 Link Down This is a basic port trap for a port down such as a PC being powered down 7) Slot-1:Module in Slot-5 is removed This seems like a module was either removed from athe card in slot one and placed back into the chassis or this issue may need to be investigated through an escalation.

Slot-1:IPv4 multicast entry not added. Hardware L3 Table Full. ( Logged at most once per hour.)

Check the below command outputs
show iproute reserved-entries statistics
show iproute summary

based on the above outputs we could say if L3 table is full or not.
If we are using any routing protocols ex:ospf,rip.
use "enable iproute compression"

Hi all,

If confirmed that the L3 table reached its limitation what could be the worse scenario? Could be total POE shutdown?

Dastan,

You have a x440, which has a limited L3 Multcast Table. If you are not running L3 multicast protocols, nor MVR, IGMPv3 or PVLAN, you may want to switch to L2 lookup. That way, you will increase dramatically the scalability (~20x). This is the mac-vlan lookup-key.

If you need MVR, IGMPv3 and/or PVLAN, mixed-mode can be a solution.

Eventually, you can just configure compression for IPMc, if you need just a bit more of entries.

You need 15.3.1+ software for the lookup-key commands.

Please refer to the Multicast EXOS Documentation for the details.
