JUNOSe 7.0.4 Release Notes > Release 7.0.4 > Release Highlights

Release Highlights

Release 7.0.4 is a maintenance release and includes the features described in this section.

DHCP

By default, DHCP relay and relay proxy broadcast DHCP Offer reply packets and ACK reply packets to DHCP clients during the discovery process. In some environments, this default broadcast method might be a security concern because all clients can receive packets intended for all other clients. The JUNOSe software supports an optional layer 2 unicast transmission method that uses the client's layer 2 (MAC) address and layer 3 (IP) broadcast address to provide secure transmission of DHCP Offer reply packets and ACK reply packets. The optional layer 2 unicast method enables reply packets to be broadcast through the layer 3 network but received only by the specified client.

You use the set dhcp relay layer-unicast-replies command in Global Configuration mode to configure the layer 2 unicast transmission method for DHCP relay and DHCP relay proxy. Use the show dhcp relay command to view whether the layer 2 unicast method is on or off.

The dhcpRelayGeneral logging event category uses the debug severity level to log DHCP reply packets that are transmitted to clients using a layer 2 unicast address and a layer 3 broadcast address.

NOTE: When you enable the layer 2 unicast transmission feature, the DHCP relay and DHCP relay proxy instance must be the next hop from the DHCP clients. Otherwise, the DHCP reply packets might be discarded.

The layer 2 unicast transmission method is not supported on non-ASIC line modules.


GRE

You can configure NAT traversal support for GRE flows using simple translations (Basic NAT). Because PPTP uses an enhanced GRE encapsulation for the PPP payload, configuring for GRE flows also supports NAT traversal for PPTP tunnels.

For more information about this feature see Appendix B, PPTP and GRE Tunneling Through NAT.

L2TP

JUNOSe software now supports an additional format for the decoding of an incoming Cisco NAS Port Info AVP 100 at the LNS. This new format supports ISDN subscribers. In previous releases, the router supported Cisco NAS Port Info AVP formats only for ATM and Ethernet subscribers.

Platform Support

For detailed information about hardware features on ERX-7xx models, ERX-14xx models, and the ERX-310 router, see the ERX Hardware Guide and the ERX Module Guide. For more information about hardware features on the E320 router, see the E320 Hardware Guide and the E320 Module Guide.

The OC3/STM1 GE/FE line module now supports the egress forwarding 2 ASIC (EFA2) hardware. The EFA2 hardware is required to support the compound shared shaper feature. Contact your Juniper Networks account representative for hardware availability.

E320 Router

The new E320 router is a next-generation, high-capacity addition to the E-series product family and offers high port density and fully redundant Internet access routing and edge aggregation. The E320 router uses the same JUNOSe software architecture and supports the same services as other E-series routers, but does so with greater capacity and scaling capabilities using new, cost-leading technology.

The E320 router addresses a wide range of edge applications, including subscriber management (including 802.11 hotspots), Metro Ethernet, customer circuit aggregation, VPNs, video on demand, Voice over IP, and wholesale services.

The E320 router supports the following types of interfaces on input/output adapters (IOAs):

To identify interfaces on the E320 router, use the slot/adapter/port format. For more information about interface types and specifiers on the E320 router, see Interface Types and Specifiers in JUNOSe Command Reference Guide, About This Guide.

The following sections describe some of the features in detail.

IP Reassembly

IP reassembly is supported on tunnel-service interfaces on the E320 router. To configure IP reassembly on the E320 router, you must install an ES2-S1 Service IOA with an ES2 4G LM.

L2TP

The E320 router supports L2TP sessions and tunnels. To use an LNS on the E320 router, you must install an ES2 4G LM with an ES2-S1 Service IOA.

LNS and LAC are supported on the ES2 4G LM with the ES2-S1 GE-4 IOA or the ES2-S1 OC3-8 STM1 ATM IOA.

Layer 2 over MPLS

The E320 router supports the same set of layer 2 services over MPLS as other E-series routers, with certain exceptions. The E320 router does not support the following layer 2 services over MPLS in the current release:

Line Module Redundancy

The E320 router supports line module redundancy. To use this feature, you must install an extra ES2 4G LM and an ES2-S1 Redund IOA in either slot 0 or slot 11.

Mixing of IOAs

The E320 router supports mixing of IOAs in the chassis. For valid IOA combinations and management information, see JUNOSe System Basics Configuration Guide, Chapter 6, Managing Modules.

Multiple Core Dumps

On the E320 router, the failure of some components on a line module generates multiple core dumps to provide more complete information about system state at the time of the failure. Other E-series routers generate only a single core dump for line module failures. When you contact Juniper Networks customer service for assistance, send all the generated core dump files.

Packet Mirroring

The E320 router now supports packet mirroring on all ATM, Gigabit Ethernet, 10-Gigabit Ethernet, and POS interfaces.

QoS

The E320 router supports QoS on the ES2-S1 OC3-8 STM1 ATM IOA. On the E320 router, the qos-mode-port command is supported on a per-port basis.

RADIUS

The E320 router supports an extended RADIUS NAS-Port format attribute for ATM, Gigabit Ethernet, and 10-Gigabit Ethernet interfaces.

The 0ssssppp or ssss0ppp format attribute set using the radius nas-port-format command does not accommodate the number of bits required by the interface specifiers on the E320 router. The radius nas-port-format extended atm and radius nas-port-format extended ethernet commands enable you to specify the number of bits for each field in the interface specifier (slot/adapter/port). In addition to specifying the slot/adapter/port fields, you can specify VPI and VCI for ATM and the VLAN and S-VLAN for Gigabit Ethernet and 10-Gigabit Ethernet.

SDX

The E320 router now supports the embedded SDX client and the Common Open Policy Service usage for policy provisioning (COPS-PR) protocol layer connection with the Juniper Networks SDX application. Use the sscc enable cops-pr command to enable COPS-PR support.

System

The following new commands enable you to manage individual IOAs on the E320 router:

Previously, you managed only the entire slot with the slot commands.

On the E320 router, you can specify the srp and fabric keywords with the following commands:

The srp keyword enables you to specify the system controller (SC) on SRP modules. The fabric keyword enables you to specify the portion of the switch fabric that is located on SRP modules.

Transparent Bridging

The E320 router now supports transparent bridging on all ATM, Gigabit Ethernet, and 10-Gigabit Ethernet interfaces.
