Dell S3048 Switch and Sticky Mac after reboot
We powered down a S3048 switch for a couple days that had learning limit and Sticky MAC enabled. When it came up no Ethernet LEDs show connectivity. We performed a Shutdown and no shutdown on all the ports no help, we performed a learning-limit reset no help, on one port we cleared the Mac-Address-Table and then performed a learning limit reset no help, when we run sh mac learning-limit violate-action it shows all ports status normal. Also the ports show Link is Up, line protocol is down. We have not disabled sticky MAC or learning limit. Assume mac-address-table disable-learning would do that? Would sticky MAC cause this or does this boil down to a connectivity or configuration problem? Does Sticky MAC or a learning limit violation cause the port LEDs to not show green or yellow? Have no experience with Sticky MAC and learning limits and very little with Dell switches. We are on OS 9 and I cannot upload any info from the switch. Any advice and help is appreciated.

Hello thanks for choosing Dell.
First of all , if you would like to enable port-security which must be enabled on global mode before configuring interface.
If the you would like to remove or disable port-security on interface level, the command below is to be executed:
DellEMC(conf)#default interface tengigabitethernet 1/1
If you would like to enable port-security on interface level, the command below is to be executed as below
DellEMC(conf)#mac port-security
Then the interface level configuration need to be configured as below
DellEMC(conf)#default interface tengigabitethernet 1/1
DellEMC(conf-if-range-te-1/48)#mac learning-limit 2 ?
dynamic Allows aging of macs eventhough learning-limit is configured
no-station-move station-move is not allowed on learnt macs (default)
station-move station-move is allowed on learnt macs
sticky Allows to configure sticky mac feature along with learning-limit
Hope this helps.

@DELL-Young E Thanks for the help. Will any idea if the port LEDs will be lights out if port security is tripped? Really wondering if we have a bad switch at this point? Performed a default interface Gi 1/1 port number and the status of the single port didn't change and no LEDs on the port on the switch. The switch still has port up / line protocol down.
