Hi,
I came across the release notes from all ISE version 1.x, 2.x and got to know the following...
https://www.cisco.com/c/en/us/td/docs/security/ise/2-3/release_notes/ise23_rn.html
Hostname |
Must not exceed 19 characters. Valid characters include alphanumerical characters (A–Z, a–z, 0–9) and the hyphen (-). The first character must be a letter. |
Per my knowledge, the limit was 15 characters for ISE host-name.
I also came across the same discussion and they mentioned the 15 characters.
Please confirm that if the limitation is changed now from 15 to 19 characters or it is a typo error and doc bug need to be filed to correct it?

In ISE 2.4 it's still 19
ise01/admin(config)# hostname ?
<WORD> New hostname string (Max Size - 19)
Below is an example of 19 character hostname (valid)
ise01/admin(config)# hostname a23456789abcdefghij
% Warning: Hostname change disallowed as this node is part of a deployment. Make it a standalone to change the hostname.
% unable to change hostname to a23456789abcdefghij
And a 20 character hostname is invalid syntax
ise01/admin(config)# hostname a23456789abcdefghijk
^
% param string too long detected at '^' marker.
