Hi Jeffery,   If you want to run Prime infra i will recommend to run over standalone server for high and better performance. i am using Prime infra server having 64Gb of ram 20 CPU and satisfied with its performance. or version 3.0 or higher 16Gb of ram is not enough to run all instance of prime.   Prime machine has 7 instance which are based on Matlab, when runs take alot of CPU utilization and memory. As per cisco recommendation atleast 32GB of ram is needed for version 3.0 or higher ... View more

Hi to All,   Regarding Prime Infrastructure performance, first of all we have to clear few things PI is managing number of operations/sec and hundred of jobs instant are running within one minute over the VM.   I have few tips which can enhance the performance of PI   1. PI performs so many operations which are schedule to poll/perform the job. there are some jobs which might not be requirement of our network infrastructure but are running on background. disable those jobs in Job Dashboard   2. Change the polling time of those Jobs which you think it need to fetch/poll the data as early like (device unreachability, Client stats,data rate operational status) etc between 5-2 min and those which are not so important early keep them to poll after 30 min this will enhance astounding performance.   3. You have to check how much jobs are polled success and how much jobs are going to failed. In job dashboard see attachment below those which are going to fail you can disable them because number of jobs failed due mismanagement of devices in network and topology find the reason and remove those devices error   4. Look into network devices delete all those devices which are added but are in unmanaged states/ long time down because prime 3.3 polls after 30 min for all those devices which are down which generate alert, email notification for them hence slow down it. Try to manage your devices wisely so that prime always polls its SNMP "Audit as Success"  5. Monitor Job dashboard ad understand it in better way. we always go with GUI in PI and say the page is not loading its getting slow but there always be a reason behind every prime error instance and performance vulnerability. its never be done by it self. Prime Infrastructure is a very strong tool and best specially for wireless network thing is we need to understand the circumstances and operation and how it works  6. Restart schedule so that its cache can have memory either by GUI or by CLI   ... View more

Hi @sandy1   in some cases it is possible that user and your vlan can pass traffic with each. by default Vlan behaviour does not allow to communicate with each other but you can allow specific vlan to communicate each other by using Trunk link    when you will make the link trunk those vlan which you want to communicate with each other can be allowed by    #switchport mode trunk  #Switchport trunk allowed vlan x,x,x,x ...

Hi waqas.mscs1075@iiu.edu.pk   Half Duplex: means two way communication. but not at the same time you can either receive or transmit like your walkie talkie phones    Full duplex: two way communication means sending and Receiving simultaneously. both at the same time.   In cisco switches by default duplex is Auto Auto. means if two devices try to communicate  with each other and one of device support half duplex they will work on half duplex. if both supports Full duplex they will work on full duplex   you can verify your catalyst 1900 series duplex speed by simple command   sh int fax/x in my case  ...

Hi,   there are two thing which you have clear when you apply ACL.  1. the interface and the device on which you applying  2. In/Out my suggestion if you want to allow well known websites like Yahoo, Google and Facebook instead of premiting them deny those to whom you want to block. Also share the topology in order to understand your gateway.   because well known websites uses so many IPs if you will permit them the user can able to access the some more websites thru facebook and yahoo  ...
