No Switchport at ARP Entries

[adminfb]

Hey HPE Community,

in the past month I have some trouble with our 5406Rzl2 switches.

Sometimes the arp entry does not contain a port int the arp table. Her an example:

IP Address MAC Address Type Port
--------------- ----------------- ------- ----
1.2.3.4 123456-abcdef dynamic Mesh
1.2.3.5 654321-abcdef dynamic
1.2.3.6 567890-fedcba dynamic A3

When I start a ping to 1.2.3.5 the request gets a timeoute even if I set the timeout to 10 seconds.

After this ping the switchport for is 1.2.3.5 is displayed in the arp table and the ping and other requests which get switched over this switch works. No matter if its a ping or a sftp request, the first try will get a timeout. The second try works perfecly fine.

I saw this on all our 5406Rzl2 switches. There are four deviced cross connected via mesh.

Could this be a case with the dynamic arp protection?

thanks!
Best regards

Finn
