Switch Log Is Full Of IP DHCP Snooping Messages- What For
My switch logs are full of these DHCP snooping messages:
May 13 12:54:59.413 EDT: %DHCP_SNOOPING-4-QUEUE_FULL: Fail to enqueue DHCP packet into processing queue: dhcp_snoop_pakQ, the queue is most likely full and packet will be dropped. May 13 12:55:29.457 EDT: %DHCP_SNOOPING-4-QUEUE_FULL: Fail to enqueue DHCP packet into processing queue: dhcp_snoop_pakQ, the queue is most likely full and packet will be dropped.
My question is why? I looked it up on the message decoder but that only tells me that there may be more DHCP messages coming in than the CPU can handle so they will be dropped to prevent a DOS attack. Then the decoder site also states that this is just an informational message and no action is required. So with that said I am not sure what is causing this and why it started today and how to stop it. What is happening with the users is they are getting that limited connectivity message that pops up when you try to get a DHCP address and it doesn't work. Has anyone dealt with this before?
