Software Versions and Fixes

NetApp's currently available patches are listed below.

Workarounds

Any of the following actions will prevent the Denial of Service condition.

1) Avoid scanning the ATTO FibreBridge running firmware 2.95.

2) Downgrade the ATTO FibreBridge to firmware 2.90.

3) If ONTAP 9.5 is in use then migrate to in-band monitoring following this action plan:

4) Disable the SNMP protocol on the ATTO FibreBridge.

To disable the SNMP protocol run the following ATTO CLI commands:
set snmp disabled
saveconfiguration

5) Disable the IP management port on the ATTO FibreBridge. Note that this will prevent the MetroCluster Health Monitor from monitoring the bridge for errors as it disables all IP connectivity to the bridge including Telnet, FTP, HTTP and SNMP.

To disable the ethernet port run the following ATTO CLI commands:
set EthernetPort MP1 disabled
saveconfiguration
