Why does my Switch hate my 250?

[NTEDave]

New install went in last week, 250 with 40 Handsets on a Netgear GS752TP doing the switching and POE.

Seemed ok at first then on go live day phones started showing "No Bandwidth for Voice" and the Message Print showed phones constantly disconnecting and re-connecting.

Pinging the 250 showed about 12 Pings received <1MS then three pings lost, pretty much spot on every time.

Changed ports, changed 250 chassis, changed leads, changed IP, nothing fixed it.

If I slave a little switch off the main Netgear and plug the 250 into it the problem nearly goes away, good pings, maybe lose 1 to every 30-40. But I get poor voice quality inbound, as in I sound good to callers but they sound slightly off to me, lost packets i'm guessing.

Anyone had anything similar and fixed it?

Fingers crossed!

NTEDave,

I have never used a Netgear switch before, but from what I can see on the datasheet it seems to be able to handle the job required.

I would verify the following.

1. Is the Netgear at the latest version of firmware.
2. Is the switch setup for QoS
  a. MiVO-250 port is set to Untagged on Voice VLAN
  b. Phones ports are set to Untagged on Data VLAN, Tagged on Voice VLAN, use LLDP-MED/CDP.

You also could just have gotten a bad switch and need to get it replaced.

Thanks,

TE

We've had an issue with the GS7XXTP Netgear switch on the MiVO250 where the LAN port on the 250 wouldn't come up with a link.
The AUX port worked ok.

We found that locking the port to 100M instead of auto negotiate fixed the issue.
I've been meaning to escalate this to Mitel to see the reasoning.

Thanks Fellas

There's no config in the switch, it has no VLANS set.

It's at the newest Firmware revision currently.

I'll give the Port Speed to 100m a go.

Cheers!
