Page title

ONTAP internal ports

Summary

The internal ports listed on this page do not properly reflect the output generated using How do I check whether a port is listening in ONTAP 9 knowledge base article.

node run -node <node_name> netstat -an

Based on digging thru the shell (system node systemshell -node <node>), and running "rpcinfo -p", it would appear the NetApp Cluster RPC starts at 900 and goes thru 1024 maybe?

Example, I had this port show up in my netstat output 943/TCP4

Not in the list (this page); however, it does show up in the rpcinfo output:

rpcinfo -p | grep 943
 536873540    1   tcp    943  cphm
 536873540    2   tcp    943  cphm
 536873541    1   tcp    943  cphm_reg

Other missing items in the netstat output also show up;

 536873328    1   tcp  11632  vldb_cache
 536873344    1   tcp  11634  spinnp_ping
 536873312    1   tcp  11636  nblade_nfsoptions
 536872196    1   tcp  11638  nitro_cifs_config

All total, 237 entries missing, many ports appear in well defined ranges and most appear in the Cluster IPSpace section.

Thank you for this feedback. I'm working with someone to enhance the ONTAP port documentation and will incorporate this topic as well.
