Linked Capacity Plus Cheat Sheet

I have created a Linked Capacity Plus configuration cheat sheet for the repeaters and routers. In this MS-Excel file, there are three sheets: one contains the diagram and the other two contain the suggested settings.

Download it here. (To download a copy, click on File>>Download)

  1. Hi Wayne,

    I have been having a look at your cheat sheet and I can't make sense of the IP addressing settings in sites two and three. Am I missing something?

    Thanks in Advance

  2. My Fault, I understand now that you have three private different networks, one per site, tied together via a 172.XXX.XXX.XXX Routed WAN network.

    Apologies for the confusion.

    Cheers

  3. Hi Wayne!!! I trying to do linked capacity plus with 3 different sites with one repeater each site. All RPTs have the same LAN, but system only work good with 2 RPTs but when connect the 3° the system fail.
    Regard and i hope your comentarious.

    1. You need to use Routers - preferably on al sites.

  5. Wayne; Can you comment on what impact to the system operation would occur if the master repeater were to fail?

    The reason I ask is I have proposed a low capacity IPSC system (60 radios 2 slots 2 or 3 talkgroups) with redundant masters plus 6 peers. The peers provide wide area coverage for two talk groups/slots at small satellite facilities. If I configure the system as linked capacity plus, I could with same hardware increase the local talk group capacity. However the master repeater would not be redundant. So the question is what will happen when the master fails. Will wide area and local calls continue unless IP addresses change? Any other drawbacks?

    1. If the Master fails, the peers will continue to operate as normal. The Master only acts as a registration point for peers joining the network and therefore is not contiguous to network operation. It does mean however, that the coverage the Master provided will go if the repeater fails, and it also means that if the Peers use DHCP service, they will drop off the network as soon as their IP lease expires (this can be avoided by using static IP addresses) and re-register with the Master.

  6. why is master ip on site 1,repeater 2 different from rest ?

    1. Because the repeaters on site 1 (and on all sites) are behind a Router - see the diagram on page 1. The Master IP for Site 1 Repeater 2, is the Ethernet IP of Repeater 1. The Master IP for the repeaters on Sites 2 and 3 is the (Static) WAN IP of the Site 1 Router.

  7. on the cheat sheet, why is master ip for site 1 repeater different ?

      The Master IP for Site 1 Repeater 1 probably could be changed to 192.168.1.2 but this wouldn't make any difference since this repeater is the Master anyway.

  8. on the cheat sheet , should each site not have its own subnet ?

    1. No because each site is behind a Router.

    1. Make sure that only TG1 is in the RX Group List for the current Personality and that the RX Group List in question is valid in the current Site List.

    2. Hi Wayne
      I have a demo LCP

      why radio´s LED turns red, as has been out of coverage

      I configured the routers and the RPT, as you indicate in your support

      if I have only 1 RPT radio works normally without the red light,
      if I connect, the RPT to the router with site 2, the LED automatically flashes red , as has been out of coverage
      Could you please let me know
      what I'm doing wrong?

      Regards

    3. Hi Wayne

      I have a demo LCP with 2 site, but I have a little issue.
      light turns red in the radio, as if you were out of coverage

      if I turn on only 1 RPT (site 1) Normal working radio does not turn on the red light
      but when you turn the other RPT (site 2) automatically the radio LED blinks red, as if you were out of coverage, but does not stop working everything else
      could you help me please

    4. It's difficult for me to say. Does the 2nd repeater generate beacons? Is the 2nd site set up in the radio? What model radio is this? Silly question: does the 2nd repeater have a different frequency to the 1st?

  12. If you are using a MikroTik RB2011 you might be interested in these config files http://bit.ly/1Oir8SV

    1. Anything else i should have to do other than restore these files to my rb2011's and match my rptrs ip's to your paperwork, So far i can not get these rb2011's and LCP to cooperate

      Delete
    2. Have a look at the screenshots at http://cwh050.blogspot.de/2012/10/linked-capacity-plus-example-router.html and replicate these settings in your router model. If you need help, have a look at the MikroTik forum http://forum.mikrotik.com/.

    3. Yeah I have tried to replicate those settings in these rb2011 routers with no sucess , i have asked in the forums over at mikrotik but so far nobody seems to know what needs to be done, I loaded your config files from http://bit.ly/1Oir8SV and set my rptrs to match that ip scheme and they will not communicate

  13. Hi Mr. Wayne,
    Can we implement a 2 site LCP system with all repeaters on a same VLAN? Each site will have 4 repeaters and and layer 2 switch. Those 2 switches are then connected through an existing building LAN.

    Thank You.

    Derrick

    1. Probably not. Multi-site Capacity Plus requires a Router at each site to handle NAT.

      Delete
    2. ....and (not) handle the broadcast traffic.

      Delete
  14. Actually that setup was implemented and we faced issues like calls from Site 1 (where the Master repeater is) can be heard in Site 2, but calls from Site 2 to 1 are not happening
