Netapp sending failed pings to cluster

Hi,

 

Disclaimer: I am not an experienced in Netapp but I can follow helpful advice

 

While monitoring our syslog, I am seeing this message:

 

2021-03-26 11:58:39 Local2.Info B1560-38A-R1R3-MGT1-INT 5880379: Mar 26 16:58:38.357 UTC: %SEC-6-IPACCESSLOGDP: list ACL-TRANSIT-MGMT-IN denied icmp 10.2.21.101 -> 169.254.64.107 (0/0), 19 packets

 

It appears that the Netapp is trying to ping an IP for one of its clusters but it is headed out its management network to attempt this. The Management switch blocks this as that IP is no beyond its ACL boundary.

 

Version 9.7P2

 

I'm not sure if there is any issue at all. IT just appears to be some strange anomaly that repeats every 3 minutes.

 

Here is some output if it helps:

If Disabling CDPD didnt Help, There is a second internal workaround for burt 1216522. Please contact Technical support.

This could be the same scenario mentioned in one of our KBs: Management port attempting to ping IPs routing through customer network - NetApp Knowledgebase

 

Can you try disabling CDP as the KB suggests?

Maffo,

 

Thanks for your response. My account is not a customer account so im unable to see the contents of the  page.

 

Can you tell me the gist of what it says or copy some of it here?

the command to disable it would be (from CLI):

::> options cdpd.enable off

 

if you require further information or you see the issue persists after this change, please open a technical case for Support team to look into this.

Maffo,

 

Sorry this doesn't appear to have had any affect.

The syslog message is still appearing.

 

Thank you for your help.
