What is causing these errors to be written to error log

iloverton — Mon, 05 Jul 2021 11:43:38 GMT

My config is a Cisco 5508 with 4x1252 LAP. for some reason I'm getting all these errors, not sure when it happen because log has over written. thanks

I think you have IPv6

I think you have IPv6 neighbour binding logging enabled.

If you refer to this guide for system messages: https://www.cisco.com/c/dam/en/us/td/docs/wireless/controller/8-6/sys-msg/b_wlc_syslogs86.xlsx it shows what these stand for.

SISF-6-ENTRY_CREATED: "Entry created %s"	6-Information	An entry was created in the binding table	This is an informational message
SISF-6-ENTRY_DELETED: "Entry deleted %s"	6-Information	An entry was deleted in the binding table	This is an informational message
SISF-6-ENTRY_CHANGED: "Entry changed %s"	6-Information	An entry was changed in the binding table	This is an informational message

If you do not require IPv6 you could always disable it globally

config ipv6 {enable | disable }

Some other good references to IPv6 on the WLC here: https://www.cisco.com/c/en/us/td/docs/wireless/controller/8-0/configuration-guide/b_cg80/b_cg80_chapter_01101.html
