Art of War
Competition with HP 3500 Series
Attacking Point
Physical 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. ERPS
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. BGP
Accurate QoS
HP 3500 sets minimum bandwidth for each queue instead of queue scheduling
mechanism. This will impact the flexibility and accuracy of QoS. SDWRR

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-UI
Green
HP 3500 does not support any green feature.
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.
Myth/Truth
Usage of flash memory
D-Link Confidential
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.
Art of War
Competition with H3C S3600 Series
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. ERPS
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. BGP
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

WFQ
DES-3810 supports Smoothed Deficit Weighted Round Robin (SDWRR) which is a
similar schedule mechanism with WFQ. SDWRR
Myth/Truth
Limitation of Smart Link
D-Link Confidential
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.
Art of War
Competition with Huawei S3300 Series
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. SDWRR
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.
Defending Point
IS-IS
D-Link Confidential
OSPF, as 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.

Myth/Truth
Sales talk of 10G
stacking bandwidth
D-Link Confidential
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.
Art of War
Competition with Cisco 3750 Series
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. ERPS
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
32G stacking bandwidth
D-Link Confidential
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.
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.

Bandwidth Control)
Multiple users/services per port, with bandwidth limit and guaranteed
bandwidth (Three Color Marker & Policing)
• Committed Information Rate (CIR): Guarantees the bandwidth of each
service by limiting the bandwidth of each other.
• Peak Information Rate (PIR): Allows services take
the unused bandwidth for better bandwidth usage.
• Traffic Policing: Drops or remarks the packet

Traffic Shaping
To lower the packet lose rate, almost all switch controllers have built-in
expensive buffer memory to prevent the data re-transmission.
Switch stores the traffic in buffer memory and delays the transmission until the
egress bandwidth is available.
However, the best-effort traffic shaping is no longer enough for the QoS
requirement nowadays.

Smoothed Deficit Weighted Round Robin (SDWRR)
Accurate and fair scheduling is required to make the egress bandwidth usage
more properly nowadays
• Fair Queue (FQ), WFQ, Deficit Round Robin (DRR), WDRR: Forward/scheduling
decision made by byte count and utilization of queues, the true weight of each queue.
