Apple Bonjour and ONTAP - Alternative to SMB ?

sanadmin_do — Wed, 05 Mar 2025 11:30:02 GMT

We have received a request from our colleagues who take care of the masOS systems:

Bonjour is based on mDNS over UDP and finds the file server on our macOS devices. I can connect to the file server with my ID by double-clicking, but I can only access certain data pools - i.e. with correctly enforced permissions for my ID. I am now wondering where this service comes from, whether this is an oversight or whether Bonjour is already being used for other purposes. Or does NetApp communicate with mDNS and UDP by default, so that it only looks like Bonjour in macOS? If Bonjour is already being used, we could test this as an alternative to SMB.

is your NetApp system broadcasting its presence over UDP 5353 (where the mDNS port is) ?

i think macOS finder is picking it for your Bonjour

if there is no mDNS, I believe Bonjour must be listening for smb/tcp services originating from NetApp' SMB port 445. This makes the detection possible.

afterall, Bonjour is only discovery mechanism

check if enabling /disabling mDNS on NetApp makes your smb://<server> appear/disappear.

run "dns-sd -B _smb._tcp" on mac and see if netapp server is listed

also, can you paste output of

vserver cifs options show -fields mdns
