TFTP L2BOOT displaying on IP phopnes

[pea123]

Hie to you all.

I am installation some IP phones. Its a new installation. The network has been existing and all ports on the switches are used up, so a new switch has been supplied. If I connect the new switch straight to the Mitel ICP my phones will work but immediately when I plug one port of my new switch to any of the existing switches the phones will start to display the above message.
The port on my new switch that I am using to connect to the other switches is configured as a trunk port. All switches are Cisco.
Does someone know what my problem could be?

Sounds like the phones aren't able to connect to the TFTP server (which, unless you're doing something fancy, is the 3300ICP controller). Make sure the voice VLAN on the new switch can reach the 3300ICP's IP address.

Best bet is the new switch needs to be configured for VLAN's

You've mentioned connecting via a trunk port but not Vlan's so Thats where I'd start.

The network has vlans configured yes,but all ports belong to the default vlan. No port on any switch belongs to those vlans.The new switch ha s acquired the vlan set up via VTP. I should point out that the phones fail to work only when I patch the new switch onto the the existing switches.
What then causes the phones to fail to find the 3300 because I would have patched the new switch onto the existing switch?

Not great at networking but here goes. A booting phone will show your messge however it should then start to download from the 3300. The new switch works when it is connected directly to the 3300 because at that point the 3300 is on the same layer 2 segment as the phones and all communications happens via MCA addresses. When you connect the new switch to other switches the 3300 in no longer on the same segment and therefore its more complicated. Not sure if we have enough info to help. Usually connecting switiches together needs a cross over cable did you need to use one or do the Cisco's auto sense the connection and flip? Is the 3300 set for tagging it packets or is it simply on the default VLAN? Is there any CDP or LLDP in use or do the phones go direct to the default VLAN?

I'd tell you a UDP joke but I'm afraid you won't get it. TCP jokes are the best because you always get them.

what is set in option 125 with regard to vlans? If its truly flat and mcd 5 then there should be no vlan setting at all....

 

[LoopyLou]

If its flat you don't really need any VLAN info but is it truly flat?

I'd tell you a UDP joke but I'm afraid you won't get it. TCP jokes are the best because you always get them.

I just left things not working over-night to do some research then found things working perfect the following morning. I guess the LAN just needed time to sort itself out although I would have loved to know what was going on & how it resolved itself.
Thank you all for your advise it did help me focus.

Sounds like VTP needed time to get it's act together and propogate the VLAN's out to the new switches. VTP is a funny animal, it can be your best friend if you understand it and your worst nightmare if you don't.
