Node name: What's the maximum length allowed?

I need to deal with the hostnames of AWS that are horrendously long. Can anybody tell me the maximum length allowed for the name of a node on the BIG-IP, respectively for v10.2.4, v11.3.0, and v11.6.0?

 

I knew of problems with long names with earlier versions, and I want to be sure that I am not running up against any limits specific to BIG-IP now, whether in relation to performance or displaying in the Configuration Utility.

 

I have read of a new feature of node names being resolved dynamically for validation, which suggests that BIG-IP can handle the maximum length allowed under the regimes of the DNS.

    Based on SOL14440:

    • Prior to v11.0.0: folder path names could be up to 1023 characters in length.
    • Since v11.0.0: folder path names are limited to 255 characters in length

    If you try to create a node name in v11.0.0 or higher with length that exceeds the maximum length, you will see an error like this: 

    0107141f:3: Failed to create the (Node). The maximum allowable length of 255 for a full path has been exceeded. The object path name was

    One thing to note is the "folder path name" includes the /Common/ part of the name, so /Common/Node1 would be considered 13 characters instead of 5. So you'd have to take into account the partition name length as well.
