If your storage system supports a very large number of CIFS clients that use ICMP pings to determine CIFS shares accessibility, you might need to increase the ping throttling threshold value.
- Enter the following command: options ip.ping_throttle.drop_level packets_per_second
packets_per_second specifies the maximum number of ICMP echo or echo reply packets (ping packets) that the storage system accepts per second. Any further packets within 1 second are dropped. The default value is 150.
