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

[kara323]

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.
