	Setting	Description
	Enable SNMP	Enables the SNMP settings fields below.
	monitoring
	SNMP version	Select the version to enable:
		•	v2c
		•	v3
		See “SNMP Versions Supported” on page 432 for a
		comparison of the two versions.
	Transport	Specify the transport protocol for SNMP
		communications:
		TCP—This protocol has error-recovery services,
		message delivery is assured, and messages are
		delivered in the order they were sent. Some SNMP
		managers support SNMP only over TCP.
		UDP—This protocol doesn’t provide error-recovery
		services, message delivery isn’t assured, and
		messages may not be delivered in the order sent.
		Because UDP doesn’t have error recovery services, it
		requires fewer network resources. It’s well-suited for
		repetitive, low-priority functions like alarm monitoring
		and is frequently used for SNMP communications.
	Port	Specify the port that the Polycom DMA system uses for
		general SNMP messages. By default, the DMA system
		uses port 161.
	Community	Specify the community name, which is the name of the
		SNMP group to which the devices and management
		stations running SNMP belong.
		The DMA system’s SNMP agent is a member of only
		one community. By default, its name is public, but you
		should change that for security reasons.
		The community name is essentially a password. The
		DMA system will not respond to requests from
		management systems that don’t belong to the same
		community.
		By itself, this provides only a minimal level of security;
		since SNMPv2c doesn’t encrypt communications, the
		community name is sent in clear text. SNMPv3 provides
		much greater security. See “SNMP Versions Supported”
		on page 432 and the v3-specific fields below.
	Contact	The name or email address of a contact person for the
		system. Required, but you can enter anything.
	Location	The location of the system. Required, but you can enter
		anything.
