I'm observing following error message on 12k router.
%TFIB-7-SCANSABORTED: TFIB scan not completing. MAC string updated.
i've confirmed that there is no arp changes occurs but cef events trigger frequenty due to high number of BGP peers ( IX / 200+)
only think i could notice is arp age time on most of the arp entries is 0 ( suspect gratious arp )
Please advice me on following cef events because "show ip cef events within 1 " shows mostly ADJ update .
does it mean some arp changes occurs ?
+00:00:00.220: *.*.*.230/32 ADJ (Gi2/0/0) update [OK]
Anyone encountered following error.
This is the explation from cisco but couldn't find any interface adjacency change , in the current enviroment.
If the TFIB scanner did not complete the first scan and the CEF scanner receives more than 60 requests to update TFIB0, then the %TFIB-7- SCANSABORTED: TFIB scan not completing messages are displayed. If the message ends with MAC string updated, such as %TFIB-7-SCANSABORTED: TFIB scan not completing. MAC string updated, then the message means that the adjacency string for an interface keeps changing. This is mostly due to a wrong setup or configuration
