Recently upgraded our network switches from a stack of Dell PowerConnect 6248P switches to a stack of Dell N3128PX-ON switches. We now have 1 printer (Lanier LD 130C) that every 58th ping goes from <1ms ping to > 2200ms or the request times out. It only does this though on the 58th ping and it is repeatable when the printer is in energy saver mode. This one device is the only one that I have found so far that has weird ping issues. Printer support company came out and replaced the network controller and no dice.
From a network switch standpoint what would be a good way to check that my switch isn't the cause?
Port config is as follows:
no green-mode eee storm-control broadcast action shutdown storm-control multicast action shutdown description "Printer" spanning-tree portfast spanning-tree portfast bpdufilter default spanning-tree tcnguard spanning-tree guard root switchport access vlan <VLAN> switchport port-security switchport port-security dynamic 1
