I have a 3750 switch stack that has had very minimal config changes over the past year.
In an attempt to locate user ports by cross-referencing the ARP and MAC tables I noticed that I only have 2 entries in the ARP table.
Both are for SVIs. However I do not see any ARP entries for roughly 100 devices. This has not always been the case, as I have used this method in the pass to locate devices' switchports. Does any know what would cause this lack of ARP entries? The MAC table is full.
Thanks in advance.
PS...I have not cleared ARP at all.
