  3. Last DesignProblems And Solutions NOV – 22 - 2010

  4. 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 ) NOV – 22 - 2010

  5. NOV – 22 - 2010

  6. NOV – 22 - 2010

  7. NOV – 22 - 2010

  8. 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 – 22 - 2010

  9. Problem 3: ( IP DHCP )Last design each PC in the switches we set static IP address ,Default Gateway and DNS server.Solution 3: 1- Faculty Domain 2- KU Domain NOV – 22 - 2010

  10. Faculty Domain :MoHE , Engineering , Literature ,Computer Science , ITCK …etcthese faculty have domain and we must configure DHCP ,DNS server in each these faculty . NOV – 22 - 2010

  11. KU Domain: We configured DHCP each switches in the faculties ,set DNS and Default gateway . NOV – 22 - 2010

  12. 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 ) NOV – 22 - 2010

  13. Core Layer NOV – 22 - 2010

  14. 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 – 22 - 2010

  15. Problem 6: (Power Server Farm)Problem the power in the Server farm some devices is failure.Solution 6:We configure one Step Lizerfor control power voltage and prevents from failure devices. NOV – 22 - 2010

  16. 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 – 22 - 2010

  17. 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 ISPwe take Public IP ( Backup ).( Show Figure ) NOV – 22 - 2010

  18. NOV – 22 - 2010

  19. 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 - 2010

  20. Part 1:We configure in the Core Layer Pix firewall. NOV – 22 - 2010

  21. Part 2:Some faculties have domain we configure Share firewall. NOV – 22 - 2010

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

  23. Problem 10 : ( Data Center )Last Design doesn’t have DataCenter .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 – 22 - 2010

  24. Data Center

  25. 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 – 22 - 2010

  26. 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 – 22 - 2010

  27. Video conference

  28. Video conferenceVideo conferencing uses telecommunications of audio and video to bring people at different sites together for a meeting.We uses H.323 protocolwe uses server AAA use database RPMS NOV – 22 - 2010

  29. Video conference componentVideo input : video or webcamVideo output: computer monitor , televisions or projectorAudio 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 telephoneData transfer: analog or digital telephone network, LAN or Internet NOV – 22 - 2010

  30. Configuration of VLANNew Design have three VLAN:1 - Data VLANStart up from VLAN 100 TO VLAN 1212 - Management VLANOnly one VLAN 503 - VOIP & Video ConferencingOnly one VLAN 200 NOV – 22 - 2010

  31. Data VLAN Each Switches have different Data VLAN.Start up from VLAN 100 T0 VLAN 121.Switch(config)#vlan 111Switch(config-vlan)#name Veterinary Switch(config)#interface range fastEthernet 0/1-20Switch(config-if-range)#switchport access vlan 111Switch(config)#interface vlan 111Switch(config-if)#ip address 10.1.255.254 255.255.0.0 NOV – 22 - 2010

  32. Configuration of DHCP & DNSWe configured DHCP in the Switch . Like this:Switch(config)#ip dhcp pool VeterinarySwitch(dhcp-config)#network 10.1.255.254 255.255.0.0Switch(dhcp-config)#default-router 10.0.0.1Switch(dhcp-config)#dns-server 10.0.0.5Switch(dhcp-config)#ip dhcp excluded-address 10.1.0.1 10.1.255.253 NOV – 22 - 2010

  33. Management VLANEach faculty we must configured management VLANAll faculty have VLAN 50 for Management VLAN.Switch(config)#vlan 50Switch(config-vlan)#name ManagementSwitch(config)#interface vlan 50Switch(config-if)#ip address 192.168.100.1 255.255.255.0 NOV – 22 - 2010

  34. VOIP & Video conferencing VLANAll faculties we must configured VLAN 200 for VOIP and Video conferencing . Like this:Switch(config)#vlan 200Switch(config-vlan)#name VeterinarySwitch(config)#interface range fastEthernet 0/21-24Switch(config-if-range)#switchport access vlan 200Switch(config)#interface vlan 200Switch(config-if)#ip address 10.200.0.1 255.255.0.0 NOV – 22 - 2010
