  1. The Network Works 800_105/c3 4

  2. Current LAN Technologies • 10/100Mbs to the desktop • 100Mbs or 1000Mbs to servers • Wireless LAN • Gigabit between Switches • Copper to Desktop, Fiber in Risers and outside • Dual Fiber/ Redundancy

  3. Current WAN Technologies • Metropolitan Area Network-own Fiber-gig or 10 gig • Within a city T1, Local Ethernet service, ATM, DSL, VPN • Long Distance Frame Relay, F/T1, ATM, VPN • Converged Networks – Voice, video, data- where it makes sense

  4. Cisco Switches • 6506 • 4006 • 3500 series • 2950 series • 1900 series • 1500 series • See www.cisco.com for features

  5. LAN Design Considerations • Traffic Analysis, IE Location & speed of servers, etc • Location and numbers in MDF and IDFs • Cost • Choke Points • Sensitivity of Applications • VLANs • QOS needs • Redundancy/ High Availability • Hot Standby Routher Protocol

  6. 6506 • 256 Gig backplane-Core switch • 6506-6 slot- one slot for Supervisor card • Sup card can include Layer 3 capability • Copper 10/100 cards • Fiber Gig cards-some need GBICs • 100FX cards

  7. 4006 • 32 Gig backplane-Core or closet switch • 4006-6 slot- one slot for Supervisor card • Sup card can include Layer 3 capability • Copper 10/100 cards • Fiber Gig cards-some need GBICs • 100FX cards

  8. Catalyst 3500 XL series • 3512= 12 10/100 copper ports and 2 GBIC slots • 3524= 24 10/100 copper ports and 2 GBIC slots • 3448= 48 10/100 copper ports and 2 GBIC slots • 3508= 8 GBIC Slots-Layer 2 only switch

  9. Catalyst 2950 series • 2950-12= 12 10/100 ports • 2950-24= 24 10/100 ports • 2950C-24= 24 1/100 ports and 2 100FX ports • 2950G-12-EI= 12 10/100 ports & 2 GBIC slots- L3 • 2950G-24-EI= 24 10/100 ports & 2 GBIC slots- L3 • 2950G-48-EI= 48 10/100 ports & 2 GBIC slots- L3

  10. Catalyst 1900 & 1500 • 1900 switches= 10Mbs • 1500 switches= very small standalone switches- limited features
