1. TamilNadu Circle Network Training

2. Purpose  Procedure to check the health of WAN equipment and WAN Links.

3. How to Check the Health of WAN Links 3 In CDR Project we use Network Node Manager (NNM) to check The health and status of Links and Routers

4. How to open NNM  Open the Internet explorer, type the URL http://10.196.208.181:7510/topology/home.

5. Cont..  Enter Login User ID and password and click submit.  The Login User ID and password for Tamilnadu Circle is as follows, CircleUsernamePassword Tamilnadu CircleTN_Userpass123

6. Monitoring Alarms  After Logging into the NNM, below screen appears.

7. Cont..  Click on the Launch View Tab.

8. Cont..  By double clicking on the launch view Tab corresponding SSA will be displayed as below.

9. 9 Cont..  By double clicking on the SSA will be displayed as below

10.  MEDIATION & PROVISIONING LINKS

11. Cont..  In Alarm Browser go to View  Set Filter. Here we can filter the alarms of Tamil Nadu Circle based on Date/Time, Node, Severity etc.  To remove filter Go to View  Clear filter.

12. What to do when Node is indicated as Down  Ping the router to check the current status of links.  If it is pinging wait for NNM screen to get refreshed. After refresh (refresh time is 15min) the links /router should turn back to normal.  If Router is not pinging Perform the following steps at Exchange end. a. Conduct the Loop test for E1 Links from Transmission room b. If Loop test is ok, Do Ping test again. c. If Ping test fails execute “Trace route “ from your PC and note IP Add where it is dropping. d. If IP Add is dropping at 172.26.x.x series Please contact NIB/MPLS and Parallely inform CDR Datacenter. 12

13. Mediation & Provisioning Link Checkup  You found all the links are ok but mediation portal still states CDR are not up to date than  It is possible that though E1 links are ok the connectivity between the router and PSTN switch is down.  Before we get into checking this part …lets understand how the PSTN switch is connected to Exchange Router. 13

25. What to check in case of CDOT switches  Communication between exchange router to CES ( Ethernet cable)  Communication between CES to IOP 0 & IOP 1.  Admn password.  Exchange router to active IOP Detailed documentation to perform tests between (CES - IOP for Mediation) & (Exchange router – IOP for Provisioning) available with ITPC. 25

26. 26 CES CONNECTIVITY TO IOP AND ROUTER

27. Check Availability of CDR Files in CES  In Windows Explorer type the URL ftp:// /cdr/blg  Type the Username & password. Request for username & password can be raised with ITPC.

28. Cont..  It opens a window which displays all the CDR files available within the CES.

29. Check Availability Of CES  First Ping to CES IP by giving the command from your desktop which access to CDR network. ‘ Ping ’  If not pinging, then try to Ping to Exchange Router IP.  If not pinging E1 links might be down. recheck in NNM  If pinging then check the interface status of fast ethernet 0/0 in NNM.

30. 30 How to Verify Definations Updation status for clients In CDR Project we use Symantec Client Security (SCS) to Protect network from Virus

31. 31  Go to Program files – select Symantec system centre console - SSCC Cont..

32. 32  Extract Symantec system center and Unlock the southdcav server group Cont..

33. 33  Give the credentials for the southdcav Cont..

34. 34  Select your server group and check the definition tab to check client def update status if definition tab not present please select antivirus view in menu bar Cont..

35. Check Infected PC.  Daily mailer from data centre list the PC ‘s infected with virus  Following report displays the details of infected PC’s of Erode SSA in Tamilnadu Circle.
