New Features in JUNOS Release 10.1 for EX Series Switches

New features in Release 10.1 of JUNOS Software for EX Series switches are described in this section.

Not all EX Series software features are supported on all EX Series platforms in the current release. For a list of all EX Series software features and their platform support, see EX Series Switch Software Features Overview.

New features are described on the following pages:

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 also 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.

Class of Service (CoS)

Port shaping and queue shaping—Port shaping and queue shaping (the shaping-rate configuration statement) is now available on EX8200 switches.

Infrastructure

IPv6 support on EX8200 switches—EX8200 switches now support configuration of IPv6 addresses.
Automatic refreshing of scripts—You can refresh commit, event, and op scripts automatically using operational mode commands such as request system scripts refresh-from commit, request system scripts refresh-from event, or request system scripts refresh-from op.
Source gateway IP address selection for relayed DHCP packets—The source gateway IP address selection for relayed DHCP packets feature allows you to use the gateway IP address (giaddr) as the source IP address of the switch for relayed DHCP packets when an EX Series switch is used as the DHCP relay agent.

Interfaces

Unicast reverse-path forwarding support—Unicast reverse-path forwarding (RPF) is available on EX8200 switches. The unicast RPF feature can be enabled on specific interfaces on EX8200 switches and supports ECMP traffic.

Layer 2 and Layer 3 Protocols

IPv6 Layer 3 multicast routing and forwarding—EX3200 and EX4200 switches now support IPv6 Layer 3 multicast routing and forwarding, which includes Multicast Listener Discovery version 1 (MLDv1) and MLDv2 to manage multicast group membership; reverse-path forwarding (RPF) to enable multicast routers to correctly forward multicast traffic to other multicast routers; Protocol Independent Multicast sparse mode (PIM SM) and PIM source-specific multicast (PIM SSM) protocols; and static rendezvous point (RP), bootstrap RP, and embedded RP to manage RP information for multicast groups.

Management and RMON

Real-time performance monitoring (RPM) support on EX8200 switches—RPM is supported on EX8208 and EX8216 switches.
SNMP MIB enhancements—The SNMP agent polls and gets details of all MIBs on EX2200 switches.

MPLS

MPLS enhancements—On EX3200 and EX4200 switches, MPLS supports class of service (CoS), IP over MPLS, and fast reroute to reroute the label-switched path in cases of link failure.

Packet Filters

IPv6 support for firewall filters on EX3200 and EX4200 switches—On EX3200 and EX4200 switches, you can apply match conditions to IPv6 traffic on Layer 3 interfaces, aggregated Ethernet interfaces, and loopback interfaces.
The following are the match conditions applicable to IPv6 traffic: destination-address, destination-port, destination-prefix-list, icmp-code, icmp-type, interface, next-header, packet-length, source-address, source-port, source-prefix-list, tcp-established, tcp-flags, tcp-initial, traffic-class
The following are the actions and action modifiers applicable to IPv6 traffic: accept, discard, routing-instance, analyzer, count, forwarding-class, loss-priority, policer
Enhancement to the interface match condition on EX8200 switches—On EX8200 switches, you can now specify aggregated Ethernet interfaces as match conditions using the interface match condition. You can configure an ingress or egress firewall filter with an aggregated Ethernet interface as a match condition and apply the firewall filter to ports, VLANs, and Layer 3 interfaces.
