4. Last Design Problems And Solutions
NOV –

5. Problem 1: (Single point failure) Single point failure in the last design. Solution 1: Add three points redundancy links in the new design ( Show figures )

9. Problem 2: ( Load ) Trunk port in the each switches configured (Load)
Problem 2: ( Load ) Trunk port in the each switches configured (Load). Solution 2: We configured OSPF in each switches Layer 3 and default route.
NOV –

10. Problem 3: ( IP DHCP ) Last design each PC in the switches we set static IP address ,Default Gateway and DNS server. Solution 3: Faculty Domain KU Domain
NOV –

11. Faculty Domain : MoHE , Engineering , Literature ,Computer Science , ITCK …etc these faculty have domain and we must configure DHCP ,DNS server in each these faculty .
NOV –

12. KU Domain: We configured DHCP each switches in the faculties ,set DNS and Default gateway .
NOV –

13. Problem 4: (Proxy Server ) Last design have one Proxy Server in the NOC. Solution 4: New design we configure four Proxy Server in the NOC. 2 Proxy Server in the NOC for redundancy ( Show Figure )

15. Problem 5: ( UPS ) Last design has UPS only in the NOC
Problem 5: ( UPS ) Last design has UPS only in the NOC. Solution 5: For redundancy two UPS in the Server Farm and each faculty has one UPS.
NOV –

16. Problem 6: (Power Server Farm) Problem the power in the Server farm some devices is failure. Solution 6: We configure one Step Lizer for control power voltage and prevents from failure devices.
NOV –

17. Problem 7: (Topology SF) In the Server farm if one link is failed all the Network KU is down. Solution 7: Full Mesh Topology Design in the Server farm if one link is down another link is up ( Show Figure )
NOV –

19. Problem 8: (Redundancy Core) In the Core layer have Router and Switch if these devices failed all Network KU is down. Solution 8: In the core layer from two ISP we take Public IP ( Backup ) ( Show Figure )

20. NOV –

21. Problem 9: ( Security ) Last design in each faculty no security firewall . Solution 9: Security Firewall for filtering in the new design we divided in three part it consist in:
NOV –

22. Part 1: We configure in the Core Layer Pix firewall.
NOV –

23. Part 2: Some faculties have domain we configure Share firewall.
NOV –

24. Part 3: Another faculties we configure ACL Firewall.

25. Problem 10 : ( Data Center ) Last Design doesn’t have Data Center
Problem 10 : ( Data Center ) Last Design doesn’t have Data Center . Solution 10 : New design we have data center in the DC we have website and each students can create account (user name and password) ( Show Figure )
NOV –

26. Data Center

27. Problem 11: (VOIP) Last design had VOIP just in the Server farm
Problem 11: (VOIP) Last design had VOIP just in the Server farm. Solution 11: In new design each faculty has two IP Phone . Call manager + TFTP, DB Publisher ,call processing…
NOV –

28. Problem 12: (Video Conference) Last design don’t have Video conference
Problem 12: (Video Conference) Last design don’t have Video conference . Solution 12: Video Conferencing is very important in the KU , We configure Video Conferencing in the some faculties. ( Show Figure )
NOV –

29. Video conference

30. Video conference Video conferencing uses telecommunications of audio and video to bring people at different sites together for a meeting. We uses H.323 protocol we uses server AAA use database RPMS
NOV –

31. Video conference component Video input : video or webcam Video output: computer monitor , televisions or projector Audio input: microphones, CD/DVD player, cassette player, or any other source of PreAmp audio outlet. Audio output: usually loudspeakers associated with the display device or telephone Data transfer: analog or digital telephone network, LAN or Internet
NOV –

32. Configuration of VLAN New Design have three VLAN: Data VLAN Start up from VLAN 100 TO VLAN Management VLAN Only one VLAN VOIP & Video Conferencing Only one VLAN 200
NOV –

33. Data VLAN Each Switches have different Data VLAN
Data VLAN Each Switches have different Data VLAN. Start up from VLAN 100 T0 VLAN 121. Switch(config)#vlan 111 Switch(config-vlan)#name Veterinary Switch(config)#interface range fastEthernet 0/1-20 Switch(config-if-range)#switchport access vlan 111 Switch(config)#interface vlan 111 Switch(config-if)#ip address
NOV –

34. Configuration of DHCP & DNS We configured DHCP in the Switch
Configuration of DHCP & DNS We configured DHCP in the Switch . Like this: Switch(config)#ip dhcp pool Veterinary Switch(dhcp-config)#network Switch(dhcp-config)#default-router Switch(dhcp-config)#dns-server Switch(dhcp-config)#ip dhcp excluded-address
NOV –

35. Management VLAN Each faculty we must configured management VLAN All faculty have VLAN 50 for Management VLAN. Switch(config)#vlan 50 Switch(config-vlan)#name Management Switch(config)#interface vlan 50 Switch(config-if)#ip address
NOV –

36. VOIP & Video conferencing VLAN All faculties we must configured VLAN 200 for VOIP and Video conferencing . Like this: Switch(config)#vlan 200 Switch(config-vlan)#name Veterinary Switch(config)#interface range fastEthernet 0/21-24 Switch(config-if-range)#switchport access vlan 200 Switch(config)#interface vlan 200 Switch(config-if)#ip address
