The SNMP agent. hostname
may be suffixed with optional SNMP agent port after colon. IPv6 addresses must be enclosed in square brackets if used with port. If FQDN is used for hostname
it will be resolved by php-snmp library, not by Net-SNMP engine. Usage of IPv6 addresses when specifying FQDN may be forced by enclosing FQDN into square brackets. Here it is some examples:
IPv4 with default port | 127.0.0.1 |
IPv6 with default port | ::1 or [::1] |
IPv4 with specific port | 127.0.0.1:1161 |
IPv6 with specific port | [::1]:1161 |
FQDN with default port | host.domain |
FQDN with specific port | host.domain:1161 |
FQDN with default port, force usage of IPv6 address | [host.domain] |
FQDN with specific port, force usage of IPv6 address | [host.domain]:1161 |
The purpuse of community
is SNMP version specific:
SNMP::VERSION_1 | SNMP community |
SNMP::VERSION_2C | SNMP community |
SNMP::VERSION_3 | SNMPv3 securityName |
The number of microseconds until the first timeout.
The number of retries in case timeout occurs.
Returns SNMP object representing remote SNMP agent.
SNMP::__construct() throws an exception when parameters count or types are wrong or unknown SNMP protocol version specified.
<?php $session = new SNMP(SNMP::VERSION_1, "127.0.0.1", "public"); $sysdescr = $session->get("sysDescr.0"); echo "$sysdescr\n"; ?>
The above example will output something similar to:
