Error opening tftp://.......................(timed out) UC500 loopback network

Hello all,

When I try to access areas through CCA (cisco configuration assistant) such as ringtones or backgrounds for the phones, I get an error message. I have attached a screenshot of the error I get

Anyone have any idea as to how I can fix this?

Re: Error opening tftp://.......................(timed out) UC50

Jason,

Firstly thanks for you patience.

We have located the issue to the default gateway of the PC not having ip routes to UC500/CUE.

So it is not always thye rocket science that is the issue.

Jason,

This looks to be a routing issue.

Can you display the running config of the router.

Jason,

This an ip routing issue

You have

!

interface Loopback0

ip address 10.1.10.2 255.255.255.252

ip nat inside

ip virtual-reassembly

!

This loopback consumes the whole network 10.1.10.0 (SubNet = .0 host .1-.2 broadcast. 3)

Your service module is clashing with the loopback

!

interface Integrated-Service-Engine0/0

description cue is initialized with default IMAP group

ip unnumbered Loopback0

ip nat inside

ip virtual-reassembly

service-module ip address 10.1.10.1 255.255.255.252

service-module ip default-gateway 10.1.10.2

You could try deleting the loop back and use the subnet as an interface vlan instead.

Save you config as it is then try

!

no int loop 0

!

int vlan 101

desc CUE SUBNET

ip address 10.1.10.2 255.255.255.252

ip nat inside

ip virtual-reassembly

no shut

!

Give it a test if it fails put it back and we can look again.

I'm a new guy so one question I have is..

Could this potentially cause any problems with incoming/outgoing calls? If not I will do it right now, but if so I will have to do it after hours.

Thanks,

Green

Sorry.

Can you hold fire on this.

I want to check a few things from your config in the morning.

Jason,

Can you provide the output of

show ip route

from the UC500

I dont think it will be very big so you should be able to paste it into the blog.

I still want to check more items in your config but I need to see the ip routing table.

I am trying to keep the required changes to a minimum.

Thanks again Jason.

My last questions for today.

Is your PC default gateway 192.168.1.5 ?

Can you ping 192.168.100.1 ?

I still think the CUE service module is IP clashing with loopback 0

We need loopback0 as it is referred to by other interfaces.

We also need the 10.10.1 address as this the CUE address used for the VM dial peers & viewmail etc.

My idea is now to try some changes.

I just need more info before I send these out.

Regards

Alex
