Attacking PointPhysical Interfaces 3500 has only 20 or 44 FE ports, less client ports.

Stacking 3500 does not support stacking which makes management of access switch much complicated. Administrators have to manage all the access switch one-by-one.

High Reliability

3500 does not support any mini-sec level ring protection protocol which is important for the reliability of campus backbone nowadays.

3500 does not have any CPU protection function like Safeguard Engine or L3 Control Packet Filtering that makes the network exposed to un-predictable virus or worm attack from mobile users in intranet. When CPU is under attack, switch becomes inaccessible and administrators are not able to cut troubled traffic off remotely, which makes the damage bigger and worse.

IPv6 IPv4 addresses are predicted to be exhausted by 2011. IPv6 routing protocols are necessary for L3 switches nowadays which HP 3500 does not support.

Painless User Authentication

HP 3500 supports only port based MAC and WAC. If there are multiple clients under the same port, there will be security breaches.

Advanced Routing

HP 3500 only supports basic RIP, OSPF without advanced routing features like PBR or BGP.

Policy-based Route enhances the security and load sharing of L3 traffic. Making the expensive L3 investment more efficiency.

BGP centralizes the L3 management of all remote sites, make management more easily

and help reduce IT expense.

Accurate QoS HP 3500 sets minimum bandwidth for each queue instead of queue scheduling mechanism. This will impact the flexibility and accuracy of QoS.

Defending Point

64K MAC addresses

DES-3810 supports only 16K MAC address which is only ¼ of 3500. A L3 switch will only learn MAC addresses of routers’ and the nodes under its owned IP

interfaces. Unless there are 64,000 nodes in the network and there is no proper IP subnet segmentation in the network, 64K MAC address table only wastes system resource and cost.

Art of WarCompetition with HP 3500 Series (Continue)

Myth/Truth

Usage of flash memory

HP claims they support 4MB on board flash and 128MB compact flash on 3500 series. Flash memory is used to store F/W and configuration files. The size of F/W files is the

key to decide how many memory space a device needs. Generally speaking, flash memory size that allows to store 3~4 firmware files is enough for an enterprise switch. Large flash size does not increase the flexibility.

DES-3810 F/W size is about 5MB, and HP 3500 is about 10MB. However, HP supports even less function than D-Link does.

Attacking Point

User Friendly

HP provides limited functions and configurations on embedded Web UI. Switch embedded Web UI shall perform the same ability to other user interfaces.

With completed configuration pages, Web UI can make the switch configuration more friendly. On the other hand, a completed Web UI support shall not need extra software and expense to customers.

All D-Link Managed Switch support completed configuration on Web-UIGreen HP 3500 does not support any green feature.

D-Link Confidential

Attacking Point

Physical Interfaces S3600 has no copper GE interface on 48 port version, making uplink among the cabinet very expensive.

High Reliability

S3600 does not support any mini-sec level ring protection protocol which is important for the reliability of campus backbone nowadays.

S3600 does not have any CPU protection function like Safeguard Engine or L3 Control Packet Filtering that makes the network exposed to un-predictable virus or worm attack from mobile users in intranet. When CPU is under attack, switch becomes inaccessible and administrators are not able to cut troubled traffic off remotely, which makes the damage bigger and worse.

IPv6 IPv4 addresses are predicted to be exhausted by 2011, IPv6 routing protocols are necessary for L3 switches nowadays which S3600 does not support..

Advanced Routing S3600 only supports basic RIP, OSPF without advanced routing features. BGP centralizes the L3 management of all remote sites, makes management more

easily and help reduce IT expense.

Painless User Authentication

Clientless user authentication such as Web-based Auth or MAC-based Auth help reduce the effort of administrators to install/configure all the clients.

H3C S3600 supports only port based MAC and no WAC support. If there are multiple clients under the same port or multiple users sharing one device, there will be security breaches.

User Friendly S3600 does not have embedded Web UI. It requires external NMS (iMC) to support

user-friendly graphic user interface. And it requires expense to customers. All D-Link Managed Switch support completed configuration on Web-UI

Myth/Truth

Limitation of Smart Link

H3C claims the performance of Smart Link is good as ERPS. Smart Link is a function that provides mini-second recovery time for switch uplinks.

When the major uplink port fails, it will switch to the backup uplink port immediately to prevent service interruption.

SmarkLink only provides fast failover for uplink ports per device basis, it’s not a global redundant protocol for whole network link ERPS or STP.

Defending Point

WFQ DES-3810 supports Smoothed Deficit Weighted Round Robin (SDWRR) which is a similar schedule mechanism with WFQ. SDWRR

D-Link Confidential

Attacking Point

Physical Interfaces S3300 does not have copper GE interface on 48 port version, making uplink among the cabinet very expensive.

Accurate QoS Huawei S3300 Series support only WRR scheduling mechanism which does not consider

the packet size when doing queue round-robin. It will impact the accuracy of bandwidth allocation if the packet size of each queue is not balanced.

Painless User Authentication

Clientless user authentication such as Web-based Auth or MAC-based Auth help reduce the effort of administrators to install/configure all the clients.

Huawei S3300 supports only port based MAC and no WAC support. If there are multiple clients under the same port or multiple users sharing one device, there will be security breaches.

User Friendly

S3300 does not support embedded Web UI for providing graphic and intuitional switch configurations. Web UI makes configuration more easier especially for entry-level users or large

cabinets with multi-vendor devices. All D-Link Managed Switch support completed configuration on Web-UI

Green S3300 does not support any green feature.

Myth/Truth

Sales talk of 10G stacking bandwidth

Huawei claims that S3300 supports up to 10G stacking bandwidth, however, there is no any 10G port or dedicated stacking port on S3300!

S3300 supports 9 switches per stack. If stacking with ring topology, there will be 10x1G cables. So that the true stacking bandwidth should be 1G.

D-Link Confidential

Attacking Point

Physical Interfaces 3750 does not have copper GE interface on both 24 and 48 port version, making uplink among the cabinet very expensive.

High Reliability

3750 does not support any mini-sec level ring protection protocol which is important for the reliability of campus backbone nowadays.

3750 does not have any CPU protection function like Safeguard Engine or L3 Control Packet Filtering that makes the network exposed to un-predictable virus or worm attack from mobile users in intranet. When CPU is under attack, switch becomes inaccessible and administrators are not possible to cut troubled traffic off remotely which makes the damage bigger and worse.

User Friendly

Web UI embedded in Cisco switches supports only dashboard monitoring. Switch embedded Web UI shall perform the same ability to other user interfaces. With

completed configuration pages, Web UI can make the switch configuration more friendly. In the other hand, a completed Web UI support shall not need extra software and expense to customers.

Cost Effective By default, Cisco 3750 embedded with IP Base Image which has only L2+ feature set,

the MSRP is $5,995 already. To enable completed L3 features, such as OSPF, BGP, & PIM, requires IP Service Image.

The MSRP is $9,990.

Defending Point

IS-IS OSPF, an Interior Gateway Protocol (IGP), is more popular and mature than IS-IS.

For medium-to-large size network such as campus, enterprise or government, OSPF is the best choice.

32G stacking bandwidth Cisco 3750 has 2 dedicated 32G Stackwise ports on each device. But the maximum data rate on the 48 port version is only 4.8G. That means rest of the bandwidth are wasted.

High Reliability S3610 does not support any mini-sec level ring protection protocol which is important for the reliability of telecom access/aggregation nowadays.

Future Proved IPTV Service

Propose multiple IPTV channels in single port to ISPs. This solution requires DHCP (relay) option 60/61, host-based IGMP (snooping), flow-based bandwidth control/CIR, traffic shaping to guarantee the services quality. However, S3610 do not support all these features.

Role of MPLS PE S3610 can only be CE of MPLS environment. It does not have the ability to build up VPN tunnels.

Improving the Management Efficiency

S3610 does not have any OAM protocol or flow collection functions (sFlow or IPFIX). Strong OAM support is a trend in ISP that help administrators manage the links or

service in the network. Initiative flow collection such as sFlow or IPFIX helps ISP monitor, analyze and locate

the abnormal traffic in real-time. Administrators can minimize the damage by taking immediate action for those troubled traffic.

L2 & L3 MPLS VPN

The Virtual Routing Forwarding (VRF) function makes S3610 possible to be the MCE of L3 MPLS environment which shares the loading of PE.

However, without LDP support, S3610 cannot be the PE of MPLS environment. VRF is not a necessary feature to Virtual Private Wire Service (VPWS). With VPWS
