BCM50 network connection weirdness

[AKviking]

I just uprgraded a BCM50 from 3.0 to 5.0 without a hitch. The customer is to be getting SIP trunks, so their BCM will now be connected to their network via the LAN1 network port (of course).

We are having issues communicating with that port if it is connected to a network switch. If I connect straight to my laptop, we have NO issues.

If I go from the LAN1 port to a network switch, and have my laptop connected to the switch, we start to have issues. A ping returns approximately 20% of the requests. Due to it's minimal communications, I cannot talk to it via HTTP or Element Manager. This is going to be a problem to get the SIP working as well.

Again, straight to the laptop works lovely.

I have tried different cables, crossover, etc.

Does the BCM 50 now support SIP trunks with Version 5? SIP from the Carrier, or between sites? I assume you have DHCP disabled on the BCM, and have the Netowork interface configured on the customer LAN?

 

[AKviking]

Yes, we added a 2 SIP trunk key code. The trunks will be between sites. DHCP is disabled and the network interface is correctly configured.

Sounds if the network is blocking the ports.

Sounds like you have an ip address conflict with another device on the customer's network. I see from your description that it was never connected to it before. Try disconnecting the BCM and then ping the address on the network to see if anything responds.

@cook1082
I thought of that, but their IT guy slapped in a fresh (dumbed down) switch. Also, it does reply with about 20% ping requests.

@telcodog
I considered that as well, but we had just the BCM and my laptop as the only devices on the second data switch we tried. Thus alleviating that possibility.

Thanks guys, keep 'em coming.
