Standard and Enhanced Images
The DGS-3120 Series is embedded with two different software images - Standard Image (SI) and Enhanced Image (EI). The Standard Image provides sophisticated features for campus, or enterprise. It includes advanced Quality of Service (QoS), traffic shaping, L2 multicasting, and robust security features. The Enhanced Image supports ERPS, Double VLAN (Q-in-Q), Ethernet OAM, Static Route, IMPB, sFlow, IPv6 features which are suitable for the next generation IPv6 networks or triple play applications in Metro Ethernet.



Enhanced Network Reliability
The DGS-3120 Series targets enterprise/campus and customers who require a high level of network security and maximum uptime. All the models in DGS-3120 series support an external redundant power supply so that continued operation can be assured. They also include other features, such as 802.1D Spanning Tree (STP), 802.1w Rapid Spanning Tree (RSTP) and 802.1s Multiple Spanning Tree (MSTP), Loopback Detection (LBD), and Broadcast Storm Control, that enhance network resilience. The G.8032 Ethernet Ring Protection Switching (ERPS) function minimizes the recovery time to 50 ms. For load sharing and redundancy backup in switch cascading/server attachment configuration, the DGS-3120 Series provides dynamic 802.3ad Link Aggregation Port Trunking. Comprehensive Security The DGS-3120 Series provides users with the latest security features such as Multi-layer and Packet Content Access Control Lists (ACL), Storm Control, and IP-MAC-Port Binding (IMPB) with DHCP Snooping. The IP-MAC-Port Binding feature allows administrators to bind a source IP address with an associated MAC and also define the port number to enhance user access control. With the DHCP Snooping feature, the switch automatically learns IP/MAC pairs by snooping DHCP packets and saving them to the IMPB white list. In addition, the D-Link Safeguard Engine identifies and prioritizes “CPU interested” packets to prevent malicious traffic from interrupting normal network flows, and to protect switch operation.

Identity Driven Network Policies
The DGS-3120 Series supports authentication mechanisms such as 802.1X, Web-based Access Control (WAC), and MAC-based Access Control (MAC) for strict access control and easy deployment. After authentication, individual policies such as VLAN membership, QoS policies, and ACL rules can be assigned to each host. In addition, the switch also supports Microsoft® NAP (Network Access Protection). NAP is a policy enforcement technology that allows customers to protect network assets from unhealthy computers by enforcing compliance with network health policies.

Traffic Management for Triple Play
The DGS-3120 Series implements a rich set of multilayer QoS/CoS features to ensure that critical network services like VoIP, video conference, IPTV and IP surveillance are served with high priority. The Traffic Shaping features guarantee bandwidth of these services when the network is busy. With L2 Multicast support, the DGS-3120 shows its ability to handle growing IPTV applications. Host-based IGMP/MLD Snooping allows multiple multicast subscribers per physical interface and ISM VLAN sends multicast streams in a multicast VLAN to save bandwidth and to provide better security to the backbone network. The ISM VLAN profiles allow users to bind/replace the pre-defined multicast registration information to subscriber ports quickly and easily.

Proactive, Effective Network Management
To uphold enterprise customers’ Service Level Agreements (SLA), service providers must reduce the Mean Time to Repair (MTTR) and increase service availability. Ethernet OAM features address these challenges and enable service providers to offer carrier-grade services. The DGS-3120 Series supports industry-standard OAM tools, including IEEE 802.3ah, IEEE802.1ag, and ITU-T Y.1731. Connectivity Fault Management (CFM) provides tools to monitor and troubleshoot end-to-end Ethernet networks, allowing service providers to check connectivity, isolate network issues, and identify customers affected by network issues.

IPv6 Technology
The DGS-3120 Series is fully compliant with the future IPv6 networks. It supports remote IPv6 manageability from telnet, HTTP, or SNMP. To create secure IPv6 networks, the DGS-3120 Series uses IPv6 ACL, DHCPv6 Snooping and Neighbor Discovery (ND) snooping functions to protect the network from illegal IPv6 clients. The DGS-3120 Series has been certified with IPv6 Ready Logo Phase 2 from the IPv6 forum, a worldwide IPv6 advocacy consortium. The IPv6 Ready Logo Program provides conformance and interoperability of IPv6 products.

D-Link Green Technology
D-Link is striving to take the lead in developing innovative and power-saving technology that does not sacrifice operational performance or functionality. The DGS-3120 Series implements the D-Link Green Technology, which includes a power saving mode, smart fan, reduced heat dissipation, and cable length detection. The power saving feature automatically powers down ports that have no link or link partner. The Smart Fan feature allows for the built-in fans to automatically turn on at a certain temperature, providing continuous, reliable and eco-friendly operation of the switch.

Manageability
D-Link’s Single IP Management (SIM) simplifies and speeds up management tasks, allowing multiple switches to be configured, monitored and maintained from any workstation running a web browser through one unique IP address. This virtual stack is managed as a single object, having all units maintained by one IP address. The DGS-3120 Series also supports standard-based management protocols such as SNMP, RMON, Telnet, Console, Web-based GUI and SSH/SSL security authentication.

A stark, brutish "Petulia" with a pistol in its pocket
It's about time this movie got released on DVD. It's odd that a film could spawn a remake ("Payback"), a glib nod ("Grosse Pointe Blank") and countless homages ("The Limey," among others) and still be as underseen as "Point Blank." The lack of a disc certainly didn't help its low profile, but of course this is a challenging, idiosyncratic movie, even three decades later. The plot is simple -- a crook is betrayed by his wife and partner and spends the rest of the movie trying to get what he's owed -- but the editing and narrative structure is unusual. What in the world did audiences possibly make of this back when it was first released? It's a remarkable film, as startling and innovative as Richard Lester's "Petulia," although admittedly it's thematically much less complex. This edition is excellent, too. Great sound, great picture and a fantastic commentary by director John Boorman and big-time "Point" fan Steven Soderbergh, who laughingly admits to Boorman that he's ripped this movie off more than a few times. Their chat is more technical than gossipy and deals heavily with the editing, the production (the script was only 70 pages long), the studio's concerns about the picture, the actors, violence, surrealism (is it all a dream?) and Boorman's elaborate use of color (the tones of clothing and sets intensify over the course of the film). I've gotten a lot of good DVD's this year but in terms of content, presentation and extas, this is one of the best.

One of Marvins better offerings
Like the Killers before marvin was almost destined to play the part of Walker in this fast moving gut wrenching but always realistic thriller brilliantly collaborated by Marvin and Boorman who had no peer in this type of film.For those unenlightened souls who downplay Marvins career this was the one that to my mind surpassed most of his prior efforts with the exception of the Killers which was above par in all respects.Marvin was ahead of the pack in the 60s playing this type of hard nosed no nonsense gangster type, no other actor came close and type casted him to some extent in this type of role which unlike may actors became a positive in his career. Just to show his brilliance as an actor he gave us later comedy roles which produced more acting accolades than that material for which he was better known namely what we see in Point Blank.He carries the whole movie as did all the great actors of that era and many since which in itself is the hallmark of greatness. Marvin was a man who so perfectly personified the parts he was playing that often other actors looked wooden in comparison.He was one of the rare individuals who could take a small co starring role and end up being the star of the movie, no mean feat when you were up against the best in the business at that time and there were plenty in the 60 and 70s.To my mind Point Blank will always be a MARVIN film and this is not to downplay other good workmanlike performances in the film but it will always rank highly in Marvins body of work which is a cut above his contemporaries in the roles for which he was known and appreciated.As for the film it played out in fairly predictable fashion until the final scenes under the golden gate brige which gave a nice twist and left the viewer unsure whether Walker did in fact take his money or simply leave the scene of the set up empty handed. The obvious answer is that he waited till the coast was clear and took his money. It is hard to accept that he did otherwise.In retrospect a movie that stands up 40 odd years later and is just as watchable as it was in 67. No mean feat.

A forerunner to Dirty Harry and Lee Marvin shining...
If you liked "The Getaway" or "Dirty Harry", then meet their forerunner. "Point Blank" is explosive, fast-paced, and still the acting is there. Good acting that is. Lee Marvin is at his best. Angie Dickinson. in her strong performance, is as beautiful as ever. Keenan Wynn and Carroll O'Connor play their parts to the hilt and it truly shows. John Vernon (who was The Mayor in "Dirty Harry") plays a slimy type with diligence and very believable. Add the killing pace of the entire picture, and you have a hot item, as sharp and cutting as "Film Noir" can be. Yes, because this is still a "Film Noir", despite the fact that it was filmed in Color and in the mid-sixties. John Boorman ("Hell in the Pacific", "Deliverance" and "The Emerald Forest"), skillfully "color coded" the entire movie, bringing it from absolute colors at the beginning, to more red-tinted ones towards the end. The only difference from a true "Film Noir" is its fast-paced storyline, that would lead us to movies as I have mentioned above. Marvin's minimalistic acting, but forceful presence, is enough to fill every frame of the movie with tension, action and complete mayhem. Compare him in "The Dirty Dozen" and "The Big Red One" and you will see what I mean. A big plus was the release on DVD. An excellent transfer with a sharp picture resolution, a clearcut sound, make it a very enticing experience to watch it at home. This is not just a Highly Recommended title. It is simply a Must!
