General Competitive and Positioning highlights-C4500
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

• Basic Layer 2/3/4 only
• layer 3 routing done in software
• Poor Layer 3 performance of 500Kpps!
• No OSPF, BGP or IS:IS• Limited VLANs and QoS
Cisco positions this Supervisor as a wiring closet access device

Switching Fabric
Example shown of 24 port 1000BT card
PerformancePerformance limited by blocking ratio of blades, each slot only has
6 Gbps bandwidth
4:14:1 4:14:1 4:14:1 4:14:1 4:14:1 4:14:1
Switching Fabric
ModulesHigh Blocking ratios through multiplexer, with no local switching causing bottlenecks
BackplaneOnly 6 single 1Gbps links to fabric, each allocated to specific ports
FabricAll switching done here even for traffic on same blade
www.h3c.com 14
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-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 networksAdvanced 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 blockingPoor 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.

Conclusion-Points to Avoid.
H3C S7500 Cisco Catalyst 4500
Nonstop Forwarding (NSF) with Stateful Switchover (SSO)
NOProvides dual supervisor engines with sub second failover. L2 sessions remain up. L3 forwarding continues during a routing event
Dynamic ARP Inspection
NO YES, Identity Spoofing with Gratuitous ARP Packets
IP Source Guard NO YES, prevent spoofing IP address
Control Plane Policing
?Provides a unified solution to rate limit the CPU-bound control plane traffic in hardware. Prevent DOS attack to CPU
MAC Authentication ?
Upon detecting a new MAC address on a switch port, the switch will proxy an 802.1x authentication request based on the device's MAC address. Provides network access to agentless devices without 802.1x supplicant capabilities.
Traffic Shaping No Yes
