Link Capacity PLus Help

[darnalljason]

have a 5 site LCP system 3 repeaters at each site. for some reason when i add site 6 it kills the system to where I have very intermittent audio doesnt matter if its a wide area call that goes to that site or a wide area call that does not go to that site


IE id 250 allsites active when site 6 is online i get intermintent audio at all sites

if i use id 251 which is programmed for sites 1,2,3 and not 6 i still get intermintent audio

Routers and all ip's are different across the system

10.0.0.1 to 10.0.0.100 for WAN address

each local is

192.168.0.1
192.168.1.1
192.168.2.1
192.168.3.1
192.168.4.1
192.168.5.1
192.168.6.1

it shows up in RDAC fine without any errors. anyone have any ideas

What's the latency between site 6 and the other sites? What type of network connection are you using for the backhaul between sites?

How many timeslots does site 6 have? If more than 2 (i.e. more than one repeater), are you using a separate Rest Channel UDP Port for each repeater at the same site?

My first guess is your issue is caused by rest channel status from site 6 being communicated to the other sites with too much latency. LCP is very unforgiving with latency. So much so, that constructing a wide-area network and relying on the Internet for networking is not going to work. Been there, done that.

Looking forward to learning more about your networking resources/setup.

Make sure you look at UDP ports also.

 

[darnalljason]

we are running a closed 5.8 ghz ethernet link between all sites

ill double check latency but is was around 25 ms

site 6 has 6 time slots

the rest channel for each site would be

0.100
1.100
2.100
3.100
4.100
5.100
6.100

ill re-run some latency tests and bandwidths tests on the ptp link in the next day or 2 when i can get back to the site. last time i tested and have documentaion i had 24 ms between site 6 and site farthest away and had 87 mbs throughput

the udp ports at each site are different

master is 50000 and they go up from there with site 6 being 50061, 62, and 63

Look at your master Site with Wireshark -- And watch what happens when you Key up --

Open a case with Motorola --

What Repeaters / Repeater firmware are you using --

Check all your "Firewall / Port mapping" in your Routers, sounds like (as someone else said) a timeout waiting for something from Site 6.

When using 192.168.x.y specifically, check everything else on the network segment for a SoHo pre-configured IP conflict. Wireshark is good for this.

What do i need to look for on wireshark

Rptr firmwareis all 2.06.00.07

Have you port-forwarded Rest Channel Port(s) at site 6, to the respective "Rest Channel IP" address?

As you know, each repeater must be behind a router. When doing your port-forwarding, the Rest Channel Port must be forwarded to the Rest Channel IP, not the Ethernet IP. And do not give the Rest Channel IP a static reservation on the router, as that will screw things up. Only give the Ethernet IP/MAC a static assignment.

You likely already know this as your other sites are working fine, but just throwing it out there. There's not much documentation in the System Planner about LCP configuration. (They want you to spend $ to take the class!).

Bad routing/firewall setup is to blame for many LCP issues.

Darnall,

Sorry, if you are not already comfortable with Wirehsark it will not help other than give you some of the data you will need to open a customer support issue.

---- But check all your mapping / NAT Mapping on the new site first as MARS suggested.

Yuck, NAT... you'd be better off using VPN tunnels through firewalls/routers if you can. Cisco's DMVPN is awesome for multi-site deployments. P25NX v2 uses DMVPN for example.

VPN is way over kill and don't need the overhead.

NAT is DISABLED im using static routes

have no issues out of 5 sites the way its configured now it only with the 6th site on it kills all sites intermittently

Just finished taking a quick look at the codeplugs you emailed, and spotted these issues. There may be more.

- Rest Channel UDP ports must be unique for each repeater

- SIT/Group/Private/Emerg timers are not consistent across all sites

- Check your privacy settings. They're not consistent across all sites. (Some are "None"; others are "Basic")

- Site 6 is not defined in your "Sites" profile in the master codeplug

- Check your RSSI Threshold in the channel config. You've got it set for -110dbm. Use a stronger value to avoid missed calls.

- One of your sites (Paducah) is set up as Site 1. This is incorrect.

- Rest Channel UDP ports must be unique for each repeater So Just to clarify each repeater at each site must have unique udp ie site 1 55000 55001 55002 etc site 2 55010 55011 u cant duplaicate udps even thought there behind a router at each site??

- SIT/Group/Private/Emerg timers are not consistent across all sites ill check those but they should be maybe i sent you some outdated codeplugs for a couple sites

- Check your privacy settings. They're not consistent across all sites. (Some are "None"; others are "Basic")OK

- Site 6 is not defined in your "Sites" profile in the master codeplugok

- Check your RSSI Threshold in the channel config. You've got it set for -110dbm. Use a stronger value to avoid missed calls. that has been changed to -85

- One of your sites (Paducah) is set up as Site 1. This is incorrect.

what should that site be it was the gonna be the master site then the master ended up being at site 2 since it was easier to get internet for remote monitoring at site 2

 

[Mars]

OK, my mistake then. Normally I make the master site, site 1. But it does not have to be that way. Just make sure each site uses a separate site number.

I didn't have a lot of time when I looked at your codeplugs earlier. The other issues I outlined are all still of concern

[com501]

The system planner suggests that they should be unique. Remember you are dealing with two separate protocols, IPv4 and UDP Both have unique properties and propagation challenges.

i figured out my problem,, dont use a backup from a mikrotik router when adding a new site,, it decides to clone the mac address
