HP 5406zl / Empty MAC addresses in the ARP table.

Hello Community,

 

We have upgraded our core 5406zl core switch to K.15.06.0017.

 

When checking the ARP table we can see some empty lines (IP but no mac @) =>

=========================================

sh arp

  172.27.1.229                                        dynamic

  172.27.1.251     00306e-c95f43       dynamic Trk1

  172.27.2.133     000c29-64d130     dynamic G5 

  172.27.2.141                                        dynamic

========================================= 

 

I cannot say if before the upgrade these empty entries were already here.

At this time the two IP addresses are not reachable.

 

My question is  : Is this output normal ? Can we consider these entries as incomplete ?  

 

Many thanks in advance.

Best regards.
