General Competitive and Positioning
highlights-C4500
Catalyst 4500 Family
Catalyst 6500 Family
H3C S7500 competes against the Catalyst 4500 series
Cisco will lead with the Catalyst 6500 and will offer the Catalyst 4500 if the 6500s
price is prohibitive
Two key differentiators for the 6500:
• High density 10 Gigabit Ethernet
• Every Feature a customer could ever want

Highlights-C4500
64Gbps, 48Mpps (28Gbps, 21Mpps in
4503) performance –
• Basic Layer 2/3/4 only
• layer 3 routing done in software
• Poor Layer 3 performance of
500Kpps!
• No OSPF, BGP or IS:IS
Supervisor II-plus
• Limited VLANs and QoS
Cisco positions this Supervisor as a
wiring closet access device
Supervisor II-Plus TS provides 12 front

High Blocking ratios
through multiplexer,

causing bottlenecks

Performance limited by blocking ratio of blades, each slot only has
6 Gbps bandwidth

General Competitive and Positioning
highlights- Catalyst 4500
Catalyst 4500 family has major drawbacks
All Switching (Layer-2 or Layer-3) carried out by Supervisor Engine
No Local Switching on the blades, all traffic goes to the Supervisor
Supervisor II+ is for network access due to poor Layer 3 support/performance, Supervisor IV & V aimed at
larger enterprise networks
Advanced QOS and Jumbo Frames only carried out on Ports with 1:1 link to supervisor II, III & IV
6 Port Gig modules
Only 6 Gigabit links from each blade to Supervisor Engine
8:1 Blocking on 48 Port Blades
4:1 Blocking on 24 Port Blades
PoE modules highly blocking
Poor investment protection
OSPF through additional $9,995 upgrade (Sup IV, V and V-10GE only)
New Chassis just re-spin of legacy Catalyst 4000
Supervisor VI engine or above required to support 4507R
Supervisor V or V-10GE required for 4510R

Conclusion-S7500 Advantages
1. Price performance ratio. S7500 reaches up to 768Gbps switching
capacity for the fabric compared to Catalyst 45 ‘s 136Gbps
2. H3C S7500 has the maximum 1.68Tbps backplane bandwidth,
which is several times bigger than Catalyst 45’s.
3. It have a maximum of 24 10GE ports, Catalyst 45 has very limited
10 GE ports and require hardware upgrades.
4. RPR and EPON support, which makes it applicable in Service
Provider networks
5. High port density for wire speed GE ports of up to 292,while
Catalyst is limited. Customers looking for a high port density switch
with rich features to deploy in the wiring closet positioning for GE to
Desktop solution, have a perfect answer-S7500 series.

Conclusion-Application example
EPON IPTV solution
H3C S7500 has various
advanced features and
it’s carrier class
architecture puts on top
for various network
applications. EPON is
just one of the many
examples I can sight
here. It provides a cost
effective solution for
Service providers as
well as Cable TV
providers. You can get

Conclusion-Key Points Against C4500
All Switching (Layer-2 or Layer-3) carried out by Supervisor Engine
No Local Switching on the blades, all traffic goes to the Supervisor
Supervisor II+ is for network access due to poor Layer 3 support/performance, Supervisor IV & V
aimed at larger enterprise networks
Advanced QOS and Jumbo Frames only carried out on Ports with 1:1 link to supervisor II, III &
IV
6 Port Gig modules
Only 6 Gigabit links from each blade to Supervisor Engine
8:1 Blocking on 48 Port Blades
4:1 Blocking on 24 Port Blades
PoE modules highly blocking
Poor investment protection
OSPF through additional $9,995 upgrade (Sup IV, V and V-10GE only)
New Chassis just re-spin of legacy Catalyst 4000
Supervisor VI engine or above required to support 4507R
Supervisor V or V-10GE required for 4510R

Conclusion-Key Points Against C4500
•
The Catalyst 4500 is based on old technology and is limited to 6Gbps
backplane performance for each line card and has no upgrade path.
H3C’s 7500 backplane can rich 1.68Tbps
•
The Catalyst 4500 line cards use simple MUX technology to multiplex
many front panel ports into the 6 Gigabit backplane connections, this
means that every packet must traverse the backplane even if its
destination port is on the same line card. S7500 line cards all provide
local Layer2 switching thus minimizing latency and the amount of traffic
that passes across the backplane.
•
The Catalyst 4500 can only support a maximum or 6 wire speed Gigabit
ports per slot for a total 32 for the 4507R or 48 for the 4510R.
•
The Catalyst 4500 requires and optional software upgrade costing $9,995
to support OSPF. S7500 supports OSPF as Standard at no extra charge.

the switch will proxy an 802.1x authentication request
based on the device's MAC address. Provides
