Design overview :Copyright © 2003 Network Solutions. All rights reserved Design overview LAN switching architecture Collapsed Core architecture with single core switch Cisco 4507R 3 Nos each of Cisco 3750 Access Switches installed at Mezz Floor, 1st Floor, 2nd Floor, 3rd Floor


Single core switch architecture :Copyright © 2003 Network Solutions. All rights reserved Single core switch architecture Note: Connectivity from other floor IDF’s is similar to that of as shown in the figure Fiber uplink Gnd Floor:65 users Core switch Mazonine Floor: 100 users First Floor:100 users Second Floor: 100 users Access Switch Access Switch Access Switch Access Switch


Single core switch Architecture- Features :Copyright © 2003 Network Solutions. All rights reserved Single core switch Architecture- Features Collapsed Core architecture ( single core switch) Access switches connecting directly to Core switch 1000BaseSX Fiber Uplink from access switch 10/100/1000Tx connectivity to servers Power supply and Supervisory redundancy support needed on Core switch for high availability Redundant modules on the core switch can also be considered for high availability Access switches connected on dual uplink ports between two interface modules


Single core switch Architecture :Copyright © 2003 Network Solutions. All rights reserved Single core switch Architecture Advantages: Redundant power supply, Supervisory engine on Core switch Low cost and simple architecture Drawbacks: No redundancy for core switch chassis failure For High availability redundant links & interface modules can be considered


Core switch Considerations :Copyright © 2003 Network Solutions. All rights reserved Core switch Considerations High Availability (Power supply and switching engine redundancy) Fast switching (High PPS) High backplane Support for distributed switching Routing protocols support for inter VLAN routing Support for Etherchannel, Fast Etherchannel, Gigabit Etherchannel Support for variety of interfaces: 10/100/1000Tx for server connectivity 1000BaseXX for backbone connectivity Support for VTP Inter VLAN and Intra VLAN Access control Lists for traffic control Support for High availability features HSRP Multimodule Ether Channel Per VLAN Rapid Spanning Tree Rapid Convergence L3 Protocols


Access switch features :Copyright © 2003 Network Solutions. All rights reserved Access switch features Support for Layer 2 and VLAN configuration 10/100Tx connectivity to desktop PoE 802.1af support for IP phones & WLAN Access Points Gigabit Ethernet Uplinks Support for Etherchannel, Fast Etherchannel, Gigabit Etherchannel Support for QoS Support for 802.1x support for network security Power supply redundancy Support VTP (client)
