Anyone got any experience of Splicecom phones as looking to get the VLAN 802.1q sorted, but trying to work out where the tagging is done, DHCP scope option or each individual phone.

Got the phone system sat on the network in a /16 setup and not VLAN'd - crap, but something I've inherited. There are QOS issues... Stuttering and that jazz.. :(

we did ours on the phones. you probably can do it from DHCP but we were advised to have them done this way.

I've found out you can currently only do it on a per phone basis, they are looking at doing it via DHCP scope options in the future.

So you config the CPU VLAN as the tagged VLAN ID and the PC Port as the untagged?
 
Can you remember in the call manager server has to sit on the same VLAN as the phones? I'm expecting is has to due to the way it multicasts.

If so looks like I'll have to raise an outage to change the IP addresses and VLANs of the call manager and modules
 
ours is on the same VLAN yes. the switches allow for the relevant routing between VLANs to allow the sesktop software to work as well.

OK what I was expecting, bugger. Oh well change request coming for a weekend on site moving the call manager and modules to the VOIP VLAN, re-ip and then telnet onto circa 200 phones change their VLAN config. If their wasn't PCs hung out the back of the phones I'd just make the VOIP VLAN on the switch the native.
 
I know the pain.

its seems such a good idea to use the switch in the phone but it causes this sort of pain further down the line.

at least it doesn't take long to change the phones via telnet.

Yup clarification over what the configs are, which phones are daisy chaining and so forth.

The reality is the network isn't in a great shape :( NFS, iSCSI, vMotion, VOIP, in fact everything on the same subnet / VLAN - rubbish. "the stock answer, /16 network and it'll be fine...." :rolleyes: :rolleyes:
 
had clients like this. its magic isnt it.

the "why do our phone calls keep dropping and chirping" on quick inspection the last client like this had half the network on 10base the other other on 1000base. to be fair the calls only dropped out when the backups started!

their in house IT had no idea why. genius!

I work for an in house IT, but sorting out previous stuff..

Apparently they've been having this issue for 2 years so been giving some people analogue phones again - really!?!

Got prob another 5 sites to look at and unravel. Default answer /16 but hang on there are only 50 devices on this network... /16!! WTF :(

I've been asked what I'd do for the NFS SANs and ESXi servers attaching.. errr prob /28 - responses, they don't like that... I'm all for carving up as much as possible, adds security if you get the ACLs in place too.
 
Certainly the core switch does, not sure if all the edge switches do. Also not sure is splicecom does.
 
I appreciate this thread is a little old but I am having an issue with some Splicecom PCS552 handsets.
At present they are on a flat network and all works fine.
I am implementing a new LAN with VLANs and I believe I need to ensure that the phone tags the voice and passes data thru to the PC untagged.
With Splicecom being what it is with no information publicly available, I have gotten the reseller to reconfigure a handset for me.
Now when it boots it gets a DHCP address for the correct VLAN, however I cannot get the attached PC to get any address.
When the phone boots it shows VLAN: CPU:10 PC:1 - is this correct for the PC, i.e does PC:1 mean untagged?
If i connect the PC to the switchport in place of the phone, the PC gets a DHCP address in the correct VLAN.
If I connect the PC via the phone and give it a static IP in the data VLAN it cannot see anything - it is as though the phone is not passing any data between the switch and the attached PC.
Any help would be very warmly appreciated.
Thanks
 
What switch are you using and what VLAN configuration have you done on the switch?

What config do you have on the phone that you've done via SSH on the phone?

Hi.
Its an HP1920 switch and I have configured a trunk port tagging the voice vlan and untagging the data vlan.

The fact that if I connect the phone or the PC direct to the switch port each gets an IP address in the correct VLAN indicates that its not the switch that is at fault.

I haven't done any configuration on the phone - I got the reseller to do that as apparently nobody else is allowed access to these.

I am hoping that the phone is just misconfigured, but will know more next week as someone is going to have another look at it.

I will report back if it works :) If it does I'll post the switchport configuration in case its any use to anyone else.

Thanks
 
telnet onto the phone via it’s IP address.
Login with password details stored in diag/7388 - I believe default
Enter the following command
setnet
Do you wish to change any of the configuration [y/n] : y

Current settings (if present) will be displayed.
Edit these to show the required values.
At any prompt you may enter '?' for help or 'q' to quit

How will the IP address be assigned: DHCP or static ?
Enter new setting or return to leave unchanged [d/s/?] : d
NFS server: x.x.x.x
TFTP server:x.x.x.x
Do you wish to configure a VPN connection [y/n] : n
Startup arguments :
Timezone :
Do you wish to use a VLAN connection [y/n] : y
CPU VLAN tag : 10
PC VLAN tag : 1
Do you wish to save this configuration [y/n/q] y
Reboot


Check that the phone is working correctly

You put in whatever the untagged van is for the port (native) in Cisco speak.

In a perfect world VLAN 1 is disabled.

Can remember if that HP switch is L3.

Out of interest are you able to post config from switch?

Sh run for SSH session, not that I think switch is the issue.

Are the phone controllers in phone VLAN?
 
The switch is only Layer2 (I think it probably has limited L3 capablilty in terms of static routing, but I am routing outside of the switch.

I will be able to post the config next week, its 'display current' btw on the switch which is the equivalent of cisco sh run. (The CLI command reference can be found on h3c.com - all HP publish is the Web UI reference which is a nightmare for configuring!)

Yes the phone servers will be in the same vlan as the phones.

Why would I need to specify the untagged VLAN for the port - the switch will tag/untag the packets to the PC connected to the phone, all the phone has to do is pass the data untagged in each direction for the attached PC - yes, I do have the native vlan (1) disabled (well, there are no ports in it and it doesnt have a SVI).
