Packet loss on Linux PC connected interface in WS-C3560CX-12PC-S

[PrabakaranBalasubramanian16319]

Hello ,

When we try to ping Linux PC from other Linux based DUT board ,we are getting 1 packet loss out of 100/200 (where Linux PC connected port in WS-C3560CX-12PC-S) .

- If we try to ping Linux PC from other device we are getting 1 packet loss.(Linux PC connected to WS-C3560CX-12PC-S).

- If we remove Linux PC from the switch WS-C3560CX-12PC-S and connect to other 4k chassis switch we dont see any issue.

- Later we have removed switch port security ,storm-control broadcast,spanning on the interfaces where LInux PC connected in WS-C3560CX-12PC-S and then we dont see any packet loss.

- My question is its due to storm-control broadcast level 1.00 command ?

Hello @PrabakaranBalasubramanian16319,

It's difficult to say definitively if the storm-control broadcast level setting was the exact cause of the packet loss, without further information about your network environment.

But, if the storm-control broadcast level is set too low (such as 1.00), it might be overly sensitive and start blocking legitimate broadcast traffic, leading to packet loss. In such cases, adjusting the storm-control level to a higher value or disabling it altogether can help alleviate the issue.

Hi

   Hard to say but why dont you return config by config?  You can start by storm control, which in my opinion would be the least likely.

OK I will try to configure one by one  and will check.

FYI, Below are the command which have configured previously. 

switchport access vlan XXX

switchport mode access

switchport nonegotiate

switchport port security violation restrict

switchport port security aging time 1

switchport port security

no logging event link status

no snmp trap link status

storm-control broadcast level 1.00

storm-control action trap

spanning-tree portfast edge

spanning-tree bpduguard enable
