    Параметри

    version

    SNMP protocol version: SNMP::VERSION_1, SNMP::VERSION_2C, SNMP::VERSION_3.

    hostname

    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 port127.0.0.1
    IPv6 with default port::1 or [::1]
    IPv4 with specific port127.0.0.1:1161
    IPv6 with specific port[::1]:1161
    FQDN with default porthost.domain
    FQDN with specific porthost.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

    community

    The purpuse of community is SNMP version specific:

    SNMP::VERSION_1SNMP community
    SNMP::VERSION_2CSNMP community
    SNMP::VERSION_3SNMPv3 securityName
    timeout

    The number of microseconds until the first timeout.
