VVX 300 network issues

[Lux]

Hello all,

   I'm having a problem with VVX 300 phones I plug them into a Brocade PoE switch and they will power on but will not get an IP address, we also have VVX 500 phones and they work fine when plugged into any of our Brocade PoE switches, the phones are all setup with DHCP which they recieve from a DHCP server. 

  Has anyone ran into this before? I'm not sure why the VVX 500's work fine and the VVX 300 are having this issue. 

VVX 300 

BootBlock: 3.0.4.0028(46135-002)

BootL1: 1.0.0.0009(46135-002)

Updater: 5.1.4.0844

Hello Lux,

welcome to the Polycom Community.

The below does not show the UC Software Version.

Therefore the Polycom VoIP FAQ contains this post here:

Most likely you would need a spanned port to check if the Phone is sending out the DHCP Discover.

Are you using any VLAN's ?

Yes we are using Vlans, and the VVX 300 isn't even establishing link so a spanned port will not show anything yet

Label: SIP
Version: 4.1.4.7430
P/N: 3150-11530-414

Hello Lux,

are you 100% sure it does not establish a physical link with the switchport ?

The only difference between a VVX500 and the VVX300 is the Gigabit network port in the VVX500.

If it fails to establish a physical link then you would require to work with your Polycom reseller to bring this to the attention of your local Polycom support team. Usually I would expect first LLDP and then CDP packets to attempt and discover VLAN's and then the normal DHCP process to take over.

I am unable to find any Brocade related cases onternally.

If you are still lurking on the board I am having the same issue.

Hello StevenTech,

welcome to the Polycom Community.

It is always useful to include the currently used software version as issues experienced may already be addressed in a newer release.

This also allows yourself and others to check against current software release notes.

The above is also stated in the "Read First: Welcome to the Polycom VoIP Forum"

Therefore the Polycom VoIP FAQ contains this post here:

Question: How can I find out my SIP UC Software Version or the BootROM Version of my Phone?
Resolution: Please check here

Stating the above I recently worked on a similar case where the phone under some circumstances failed to establish a network link if the Switch port in question was set to gigabit.

Can confirm if yours is gigabit and try and set for 100FD instead.

An update to UC Software 5.1.1 or later should address this.
