Hardware

EX2200 switch The EX2200 switch is a fixed-configuration switch that is
available in four models 24-port or 48-port models with either all ports equipped
for Power over Ethernet (PoE) or none of the ports equipped for PoE.
All EX2200 models provide network ports that have 10/100/1000BASE-T Gigabit
Ethernet connectors and uplink ports that support 1-gigabit small form-factor
pluggable (SFP) transceivers for use with fiber connections and copper
connections. For information about software features supported on the EX2200
switch, see
EX Series Switch Software Features Overview
The following optical interfaces are supported on the EX2200 switch:
EX-SFP-1GE-T (1000BASE-T, 100 m)
EX-SFP-1GE-SX (1000BASE-SX, 220 m, 275 m, 500 m, or 550 m)
EX-SFP-1GE-LX (1000BASE-LX, 10 km)
EX-SFP-1GE-LH (1000BASE-LH or 1000Base-LH, 70 km)
EX-SFP-1FE-FX (100BASE-FX, 2 km)
EX-SFP-FE20KT13R15 (100BASE-BX-U, 20 km)
EX-SFP-FE20KT15R13 (100BASE-BX-D, 20 km)
New optical transceiver support The 8-port 10-Gigabit Ethernet SFP+ line
card in EX8200 switches now supports one new optical transceiver:
EX-SFP-10GE-ER (10GBase-ER, 40 km).

Access Control and Port Security

Captive portal authentication Captive portal authentication allows you to
authenticate users on EX Series switches by redirecting Web browser requests
to a login page that requires users to input a username and password before
they are allowed access to the network. In addition to using the feature to control
network access by requiring users to provide information that is authenticated
against a RADIUS server database, you can use it to display an acceptable-use
policy to users before they access your network. An authentication whitelist
allows you to specify MAC addresses that are allowed to bypass authentication.

Bridging, VLANs, and Spanning Trees

Proxy ARP Proxy ARP can be configured on a per-VLAN basis, in either
restricted or unrestricted mode.
IPv6 unicast VRF support EX Series switches now support IPv6 unicast virtual
routing and forwarding (VRF) traffic.
Private VLANs Private VLANs (PVLANs) are now supported on EX8200 switches.
