Hardware

40-port SFP+ line card for EX8200 switches—EX8200 switches now support the new 40-port SFP+ line card. It is a hot-removable and hot-insertable field replaceable unit (FRU) that can be installed in the line card slots on the front of the switch chassis. The line card has 40 oversubscribed 10-gigabit SFP+ ports on the faceplate in which you can install either SFP+ or SFP transceivers.
The line card supports the following SFP transceivers:
- EX-SFP-1GE-T (1000Base-T, 100 m)
- EX-SFP-1GE-SX (1000Base-SX, 220 m, 275 m, 500 m, 550 m)
- EX-SFP-1GE-LX (1000Base-LX, 10 km)
- EX-SFP-1FE-LH (100Base-ZX, 80 km)
The line card supports the following SFP+ transceivers:
- EX-SFP-10GE-USR (10GBase-SR, 10 m, 30 m, 100 m)
- EX-SFP-10GE-SR (10GBase-SR, 26 m, 33 m, 66 m, 82 m, 300m)
- EX-SFP-10GE-LRM (10GBase-LRM, 200 m)
- EX-SFP-10GE-LR (10GBase-LR, 10 km)
- EX-SFP-10GE-ER (10GBase-ER, 40 km)
The line card supports the following SFP+ direct attach cables:
- EX-SFP-10GE-DAC-1m (1 m)
- EX-SFP-10GE-DAC-3m (3 m)
- EX-SFP-10GE-DAC-5m (5 m)
- EX-SFP-10GE-DAC-7m (7 m)
New optical transceiver support—EX3200 and EX4200 switches now support one new optical transceiver: EX-SFP-10GE-ER (10GBase-ER, 40 km).
New optical transceiver support—EX4500 switches now support one new optical transceiver: EX-SFP-1GE-SX (1000Base-SX, 220 m, 275 m, 500 m, 550 m).
SFP+ direct attach cable support—EX3200 and EX4200 switches now support four SFP+ direct attach cables:
- EX-SFP-10GE-DAC-1m
- EX-SFP-10GE-DAC-3m
- EX-SFP-10GE-DAC-5m
- EX-SFP-10GE-DAC-7m
SFP+ direct attach cable support—EX8200 switches now support one new SFP+ direct attach cable: EX-SFP-10GE-DAC-5m.

Access Control and Port Security

Captive portal authentication functionality enhancements—Limitations on captive portal authentication functionality are removed. Captive portal functionality no longer requires that a routed VLAN interface (RVI) be created or that the switch's DHCP gateway IP address be configured as the IP address of the RVI.
Captive portal authentication can now be configured on the same interface with both 802.1X and MAC RADIUS authentication. Authentication fallback is enabled on an interface on which more than one type of authentication is configured. Captive portal authentication is supported on EX3200 and EX4200 switches.
MAC RADIUS authentication on EX8200 switches—All MAC RADIUS authentication functionality available on EX3200 and EX4200 switches is extended to EX8200 switches.
Additional 802.1X features support on EX8200 switches—Support for the following features related to 802.1X that are available on EX3200 and EX4200 switches is extended to EX8200 switches:
- Static MAC bypass of authentication
- Guest VLANs
- Per-user firewall filters
- Voice VLAN assignments
- Vendor specific attributes (VSAs)

Infrastructure

IPv6 support on EX2200 switches—EX2200 switches support IPv6 addresses for in-band management on the management interface and on network interfaces.

Layer 2 and Layer 3 Protocols

IPSec support for OSPFv3—IPSec can be used to secure OSPFv3 interfaces and protect OSPFv3 virtual links by authenticating and encrypting each IP packet of a data stream.
IGMP snooping EXCLUDE modes—IGMP snooping now supports IGMPv3 EXCLUDE and EXCLUDE NULL modes.

Management and RMON

Remote performance monitoring (RPM) enhancements—To specify timestamping of RPM probes icmp-ping, icmp-ping-timestamp, udp-ping, and udp-ping-timestamp, you can configure hardware timestamps on the requester.
SNMP MIB enhancements—Power supply MIB definitions have been introduced for monitoring and managing power on an EX Series switch.

Packet Filters

Firewall filters with dynamic TCAM allocation on EX8200 switches—Dynamic allocation of ternary content addressable memory (TCAM) to firewall filters is supported on EX8200 switches.
Firewall filter IPv6 support on EX8200 switches—Firewall filters for IPv6 traffic are now supported on EX8200 switches.

PoE

PoE+ support on EX2200 switches—The EX2200 switch now supports IEEE 802.3at (PoE+). Each PoE port can provide up to 30 W for powered devices.
