Vivian: How do you position these switches with respect to other Cisco aggregation switch

offerings?

Madhu: Well,first, it is very important to understand that the Catalyst 3560E-12D and 3560E-12SD

offer a complementary aggregation solution to other modular Cisco switching solutions, such as the

Catalyst 4500 and the Catalyst 6500 Series. The sweet spot of the Catalyst 3560E-12D and

3560E-12SD is the aggregation deployment where there are space and power constraints or where

1Gig and 10Gig networks must coexist.

Vivian: Let's talk about the major concerns of the aggregation layer:

High availability

●

Network traffic management

●

Ease of management

●

How does Cisco address the customer needs in the aggregation layer through these switches?

Madhu: Let's walk through each area one by one.

First, network uptime is enhanced with dual hot-swappable power supplies and four redundant

field-replaceable fans in the Catalyst 3560E-12D and 3560E-12SD. Users can choose from any

combination of AC and DC power supplies. Also, applications enjoy high availability due to dynamic

Layer 3 capabilities such as OSPF, BGP, and EIGRP and also due to the presence of dual uplinks.

Also, Virtual Route Forwarding Lite, or VRF Lite, enables two or more VPNs with overlapping IP

addresses to coexist. The IP Services feature set is required for these capabilities.

Second, QoS features in these switches include L2 to L4 classification, policing, traffic shaping, and

advanced congestion control. This enables effective management of real-time voice, video, and

data traffic.

Third, Generic On-Line Diagnostics, or GOLD, checks the health of hardware components and

verifies proper operation of the system data and control plane at run time.

And like the other Catalyst 3560E Series Switches, the Catalyst 3560E-12D and 3560E-12SD can

be managed using CiscoWorks LMS, Cisco Network Assistant, and Smartports macros.

Vivian: Madhu, you mentioned earlier about "mixed 1GE and 10GE deployments." Would you

please elaborate?

Madhu: Sure. The TwinGig Converter module essentially converts a 10 Gigabit Ethernet X2

interface into two 1 Gigabit Ethernet Small Form-Factor Pluggable (SFP) ports. This way,

customers can initially use the switch with 1 Gigabit Ethernet uplinks and later upgrade to 10

Gigabit Ethernet uplinks as business demands change, without having to upgrade the whole

access layer. This 1 Gig to 10 Gig upgrade can be done literally in 10 seconds at no additional

cost!

Vivian: Great! Just to summarize and make sure that I get all the benefits.

First, the Cisco Catalyst 3650E-12D and 3650E-12SD add new aggregation solutions that are

highly available and easy to manage to our total switching portfolio.

Second, these switches enable customers to easily implement or upgrade to the 10 Gigabit

Ethernet uplinks as their businesses grow, providing greater operational flexibility and further
