There are two PoE power mode settings on the EX3300 switches:
• Static mode, which allows customers to specify the
maximum PoE power setting on an individual port
• Class mode, which allows end devices to specify PoE class
and negotiate whether the switch can provide PoE power to
the device
The EX3300 also supports the industry-standard Link Layer
Discovery Protocol (LLDP) and LLDP-Media Endpoint Discovery
(LLDP-MED), which enable the switches to automatically
discover Ethernet-enabled devices, determine their power
requirements, and assign virtual LAN (VLAN) parameters. LLDP-
MED-based granular PoE management allows the EX3300 to
negotiate PoE usage down to a fraction of a watt on powered
devices, enabling more efficient PoE utilization across the switch.
The EX3300 supports the Institute of Electrical and Electronics
Engineers (IEEE) 802.3az standard for Energy Efficient Ethernet
(EEE) functionality, reducing power consumption of copper
physical layers (PHY) during periods of low link utilization.
In addition, the EX3300 supports rich quality-of-service (QoS)
functionality for prioritizing data, voice, and video trac. The
switches support eight QoS queues on every port, enabling them to
maintain multilevel, end-to-end trac prioritization. The EX3300
also supports a wide range of scheduling options, such as priority
and shaped deficit weighted round-robin (SDWRR) scheduling.
An external redundant power system (RPS) delivering additional
power resiliency is also available.
Data Center Gigabit Ethernet Server Access
The EX3300 switches are optimized for GbE server access
deployments in the data center, with front-to-back and back-
to-front cooling. The four SFP+ uplink ports on the EX3300 can
operate at 10 Gbps simultaneously, offering up to 20GbE of uplink
connectivity to each of the dual aggregation switches.

Security
The EX3300 switches fully interoperate with Juniper Networks
Unified Access Control, which consolidates all aspects of a user’s
identity, device, and location, enabling administrators to enforce
access control and security down to the individual port or user
levels. Working as an enforcement point within the UAC, the
EX3300 provides both standards-based 802.1X port-level access
control and Layer 2-4 policy enforcement based on user identity,
location, and/or device. A user’s identity, device type, machine
posture check, and location can be used to not only grant or deny
access but also to determine the duration of access. If access is
granted, the switch assigns the user to a specific VLAN based on
authorization levels. The switch can also apply QoS policies or
mirror user traffic to a central location for logging, monitoring, or
threat detection by intrusion prevention systems (IPS).
The EX3300 also provides a full complement of port security
features, including Dynamic Host Configuration Protocol (DHCP)
snooping, dynamic ARP inspection (DAI), and media access control
(MAC) limiting to defend against internal and external spoofing,
man-in-the-middle, and denial-of-service (DoS) attacks.
