Unable to edit the issue, but this is with trunk r87213.

Warning seems to be added in 5.8, released in 2018-07-16.
Port to be included (colon-separated) in session.peername.

snmplib: Mark snmp_session.remote_port as deprecated

Ensure that the compiler issues a warning if a value is assigned to
remote_port. This member has been deprecated a long time ago.

(1) Minimal final version 4.2.7.1 2008-06-09 supports both peername and remote_port see http://www.net-snmp.org/dev/schedule.html and http://www.net-snmp.org/download.html
However version 5.0.11.2 2008-06-19 and upwards only support peername.
Both versions reached end of life and current LTS version is 5.4.x released in 2011-06-24 that also supports only peername.

So it is suggested to simply remove redundant deprecated parameter.
If someone still uses 4.2.7.1 then it will still work due to existing code:

	zbx_snprintf(addr, sizeof(addr), "%s:%hu", item->interface.addr, item->interface.port);

MVekslers I agree. Since even CentOS31 uses net-snmp-5.0.9
RESOLVED in r87657.

vso CLOSED
