Voice and Data Vlan Routing for CUPC and IP Phones ?

The IP Phones are in 10.1.1.0/24 network (Voice Vlan 10) , Desktop Computers are installed with CUPC 8.5 and they are in 11.2.2.0/24 network (DATA VLAN 20) , Unfied Communication Applications like CUCM , Cisco Unified Presence Server, Contact Center Express are in 172.16.10.0/24 network(Vlan 30). When using Clients like Cisco Unified Personal Communicator, How the Communication between CUPC(DATA Vlan)and IP Phones(VOICE Vlan) is possible?.How network should be configured or designed ? If i make intervlan routing it creates Security problems.what is the best practiced network Configs for these kind of Scenario ? Even if i prefer to configure Intervlan routing, Which all TCP/UDP ports are to be allowed / blocked between VLANS ??

Hi Mohammed,
Hosts on separate vlans communicate with each other through routing, as they are not in the same broadcast domain. Some of the systems you mention use a wide range of ports and, depending on system and installed version, documentation is generally available.
e.g
http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/port/8_5_1/portlist851.html
or
http://www.cisco.com/en/US/docs/voice_ip_comm/cupc/8_5/english/release/notes/cupc85.html#wp39407
Be also aware that RTP communication uses extended ranges of ephemeral ports.

U-verse voice and multiple phone lines for small business

Our business has one phone number we want the clients to have, but four phone lines--each with a different number. Consequently, when we call out from one of the phone lines, one of the four numbers shows up, but we only want our one business number to show up so people can have that number. We get billed for the four seperate phone lines and u-verse voice. Is U-verse voice in any way connected to these phone lines? Why do we have u-verse voice and four seperate phone numbers?

Hi
If there are several telephone lines that are being used simultaneously, they all need separate phone numbers. Our team will be happy to look into your business phone options. You can send us a private message by clicking here. Please include your full name, phone number, account number and the best time you can be reached.
Please let me know if you have any questions.

Voice and IP Phone response delay

All,
We are experiencing an issue with voice delay and even phone response delay during the beginning of a call. When a user picks up the phone there is a noticeable delay before any audio is actually heard (2-5 seconds). Users also complain that they are unable to answer the call, meaning they hit the speaker phone button on the phone but it doesn't repond for a few seconds.
There is an ASA (version 8.4(3)) that is in between the call managers and the remote locations with the IP phones.
I have already checked QoS from the CUCM all the way to the remote end. It is good. I have also not found any packet loss over my network or the carrier network. I do not have access to the data center or the ASA. I currently have the people responsbile trying to prove out their side but I need some ideas on possible problems? Also, has anyone else experienced this and if so what was the problem and the fix?
CUCM Version: 8.6
Phone Load: SCCP42.9-2-3S
Thank you!
Message was edited by: Preston Hartley
Update: The problem does not present itself on every call, when it does happen I see multiple packet retransmissions in wireshark.

The next step I would reocmmend is to run a Wireshark at both the phone and the CUCM node to which the phone is registered. This would let you see what happens: is the packet lost, arriving too late, corrupted, fragmented, etc.
https://supportforums.cisco.com/docs/DOC-11599
The ASA code is capable of doing Layer 7 inspection/manipulation of the SCCP traffic. It could have a bug where it doesn't understand the newer SCCP version or it could be rate limiting the connections to each CUCM server.
Another possibility is that there is traffic shaping somewhere which is delaying delivery of the packets. Again, seeing both sides is probably your best next bet.

Inter VLAN Routing for IEC 61850

Hello,
Hoping someone can help me with this query. I'm in the process of configuring two CGS2520 switches located in two electrical substations. Each of these switches have Protection Relays and Remote Terminal Units (RTUs) connected to them. These devices communicate with each other as follows:
IEC 61850 GOOSE: http://en.wikipedia.org/wiki/Generic_Substation_Events
IEC 61850 MMS: http://en.wikipedia.org/wiki/IEC_61850
- Protection Relay to Protection Relay communication within either substation (Using IEC 61850 GOOSE - VLAN 11 and VLAN 21)
- Protection Relay to Protection Relay communication between substations (Using IEC 61850 GOOSE - VLAN 50)
- RTU to Protection Relay (Using IEC 61850 MMS - VLAN 10 and VLAN 20)
I've attached an image (hope that clears things out). Basically GOOSE traffic is VLAN tagged and and the MMS traffic is untagged.
I need to be able to route between VLAN 10 and VLAN 20 between the substations and I want to allow VLAN 50 between the substations. How do I go about configuring this?
So far I've configured the interfaces as follows:
Switch A2:
Fa0/5 and Fa0/7 (Protection Relay Ports)
port type nni
switchport trunk native vlan 10
switchport trunk allowed vlan 11, 50
switchport mode trunk
Fa0/3 (RTU Port)
port type nni
switchport access vlan 10
Switch B1
Fa0/4 and Fa0/5 (Protection Relay Ports)
port type nni
switchport trunk native vlan 20
switchport mode allowed vlan 21, 50
switchport mode trunk
Fa0/3 (RTU Port)
port type nni
switchport access vlan 20
Locally at each substation this seems to work (I can ping the Protection Relays from the RTU port and the Protection Relays send each other GOOSE messages). However I don't know how to configure the inter vlan routing (I want to be able to ping a Protection Relay Substation B from the RTU Port at Substation A) at and how to configure the switch interfaces that connect to each other?
Any help is much appreciated.
Thanks

Hello DarshanaD,
Could you fix this? Im asking because I have the same problem right now.
I'll appreciated if you can tell me how did you configure the inter VLAN routing.
Thanks

Saving all data in preparation for a possible replacement phone

Hello,
Long story short - I may be getting a replacement iPhone for the one I currently have.
I haven't handed my phone over just yet because I want to make 100% sure that all my data is properly saved and how I should be giving it back to Apple.
Everything is in iTunes - music, podcasts etc etc, so I'm hoping that just hooking up the new iPhone and syncing will put all my data onto the new iPhone? Is this the same process with the apps? They're in iTunes as well, so again just hook up and sync and I won't have any dramas? Or do I have to redownload? If so, what happens with the apps that I've paid for, I don't want to pay for them again.
In terms of what I'm going to lose, I can only think of my contacts (they're not synced up with iTunes, I just put them in manually), my e-mail accounts I've added any photos that I haven't synced over and my SMS conversations. Is that about it?
Next question is - how do I give it back to Apple? Should I be taking all my music, apps etc off? Deleting my contacts and SMS conversations etc? Or just leave it all as is?
Any other advice would be great! Cheers.

iTunes creates and maintains a backup for your iPhone, which is updated at the first step during the iTunes sync process. This link provides the data included with your iPhone's backup.
http://support.apple.com/kb/HT1766
Although contacts are included with your iPhone's backup, it isn't a good idea to depend on your iPhone's backup alone for this data since the backup includes other data. If there is a problem with your iPhone's backup or with some of the data included with the backup and you aren't able to restore your iPhone from your iPhone's backup or transfer the backup to your new iPhone, kiss your contacts goodbye. Contacts are designed to be synced with a supported application on your computer. With Windows, this can be with Outlook 2003 or 2007 along with syncing calendar events and iPhone Notes, or with Windows Contacts for syncing contacts only. With a Mac, this can be with the Address Book for contacts, and iCal for calendar events.
Since you aren't currently syncing contacts with a supported application on your computer and if the supported application on your computer to be used does not include any contacts, before syncing contacts enter one contact in the supported application on your computer. Make this contact up if needed, which can be deleted later. This will provide a merge prompt with the first sync for this data, which you want to select.
Although photos in your iPhone's Camera Roll are also included with your iPhone's backup, photos in your iPhone's Camera Roll should be imported by your computer as with any other digital camera. Be sure to import these photos by your computer before your iPhone is exchanged.
There is no device limit for the number of iPods and/or iPhones that can be synced with the same iTunes library and iTunes account on the same computer including 3rd party apps. You will be able to transfer your 3rd party apps to your new iPhone along with all other iTunes content.
SMS/MMS are also included with your iPhone's backup.
Before your iPhone is exchanged, import the photos from your iPhone's Camera Roll. Then sync your iPhone with iTunes to update your iPhone's backup along with any data kept synchronized with a supported application on your computer such as contacts.
If you don't want to return your iPhone with any data on it, on your iPhone go to Settings > General > Reset and select Erase All Content and Settings. This is a secure erase and will take an hour or two so have your iPhone connected to a power source when doing so .
The first time you connect your new iPhone to iTunes, you will be prompted to register the iPhone followed by transferring the backup for your existing iPhone. After the backup is transferred, this will be followed by a sync to transfer your selected iTunes content under the various tabs for your iPhone sync preferences, which will be pre-selected under the various tab for your new iPhone sync preferences based on what is selected under the various tabs for your current iPhone sync preferences.

802.1x MDA with Cisco 3750, ACS and Avaya phones

Hello,
What is the minimum software level on the C3750 to support the 'device type class=voice' AV-pair returned by ACS? I found 12.2(35) introduced MDA, but also I found 12.2(40) required for dynamic voice VLAN on MDA ports.
What i observe is :
- phone connects
- phone is dot1x authenticated in data VLAN and gets its DHCP address there
- DHCP advertises (option 242) the voice vlan id
- phone reauthenticates in voice vlan
- phone reacquires a new DHCP address, now in voice VLAN
so far so good ... and we start using the phone
- pc behind phone starts and enters credentials
- pc authenticates ok (in data vlan)
but 3750 shuts the port down per security violation ("new mac-address found").
The mac-address of the phone stays in the data vlan's mac table, despite the phone moved correctly to the voice vlan. This macaddress excludes the 'new' pc mac-address, causing a shutdown of the port.
NB : "setting port-security max mac-addresses" to say 5 does not change anything to this behavior.
Can anybody give some hints?
Tx.

Searching further, I found that 12.2(40) requirement for dynamic voice VLAN on MDA ports only applies to dynamically provisioning the voice vlan ID by radius, applying the (65)tunnel (medium) type and (81) tunnel private groupid attributes. So, obviously, MDA support with 'static' voice vlan assignment by switchport configuration *should work* with our 12.2(35), *
So, the question remains : why does the data VLAN keep an entry with the phone's MAC address in its MAC table?
Tx.

HELP! Does anyone know a Data Recovery Expert for I-CIoud? -My calender disappeared during I-Cloud transfer of data from old I-Phone 4 to new I-Phone 5s. It was on both I-Phones then vanished. (It was evidently not syncing during back-ups on the laptop)

HELP! Does anyone know a "Data Recovery Expert" for I-Cloud & I-Phone? - My calendar disappeared during I-Cloud transfer of data from my old I-Phone 4 to my new I-Phone 5s. It was on both I-Phones then vanished. (It was evidently not syncing during back-ups on the laptop)
The Apple techs are looking. But they can't find it. Nor can they find a back up on my laptop, Evidently when I backed up my Iphone to computer the calendar wasn't syncing. Since I only use the calander on my phone - I never noticed.
The Apple store rep that sold me the I-Phone 5 on Monday, was transferring my contacts and calendar thru I-Cloud (I never used I-Cloud before that moment - and always had it turned off). He successfully transferred the contacts - which are still on my phone), but the Calendar weirdly split into 6 calendars (2 of which were linked to my G-Mail which only had a few entries) (4 were linked to my MSN / Hotmail email and contained all the major events/data). I never created calendars that were separate or liked them to 2 different emails. I just typed entries into the I-Phone calendar. However, the calendar did exist on the new I-Phone for 24 hours. Something happened during transfer. When the Apple Genius Bar tech was attempting to back up my Calendar & merge the 6 calendars, everything disappeared in his hand while he was looking at it.
I am hoping that some really good data recovery expert exists that can restore the calendar that was in both I-Phones yesterday. It is completely devastating if I can't recover it.
Any help, or referrals, is great appreciated!!!!
Thanks!

Port with multi-vlan for voice and data??

Hi guys,
I've a situation where my VOIP and DATA on a different segments. Voice is 10.x.x.x riding on VLAN 701. And my data is 192.x.x.x riding on VLAN 100.
The problem occur when our receptionist PC have a software installed for call forwarding for our general line. This software need to be on the same vlan with the IP Phone vlan which is 701. If I put her PC on those vlan, she can't access
to our LAN which is vlan 100. So she can't check her email etc.
Can I know what is the options I have? Can I configured multi-vlan for her PC on the switch? We are using Cisco PoE 3560 switch. Thanks.

Hi,
on the L3 switch, you should have an IP address for both VLAN 701 and 100. So, the L3 switch is doing inter-VLAN routing.
This means, unless you have ACL blocking traffic, any device will be able to reach any other device, even on a different VLAN.
And, no matter where you put voice and applications, everything will work anyway.

Vlan for voice and vlan for data with diferent ISP best choice of config??

Hello everyone,
Im, Oscar
At our company we have a redundant ISP connection to two separate ISP's.
We are also using VoIP on the network.
Currently one ISP connection is used primarily and the second on is just used as a backup.
I was wondering if it is possible to use the first connection primarily for data traffic and the second connection for VoIP traffic?
We use different VLAN's for voice and data.
Any help would be appreciated.

Configure Voice and Data VLAN in CISCO SF 300 8P

I have a couple of Cisco SF 300 8P and 24 P Switches. I have voice and Data VLAN configured as :
Data VLAN : Default 145.17.59.0/24
Voice VLAN : VLAN 20 172.22.20.0/24
I have different DHCP servers as for Data VLAN we have physical server which is configured for 145.17.59.* IP Scope and Voice VLAN DHCP Server is configured in Gateway router with option 150.
This configuation works fine with other cisco swiches like 2960 and 3750 etc except CISCO SF 300 8P and 24P. I was trying to configure both voice and Data VLAN in these CISCO Switches so that CISCO phone (Model 6941) shold get IP from Voice VLAN and PC should get IP from Data VLAN DHCP Server. I have tried several techniques like LLDP, Port to VLAN Config etc.
Can anyone please guide me/help on this.
Regards,
A K.M.Sayeed

Hi A.K.M., with Cisco phones you should be able to simply set auto voice VLAN to be VLAN20.
voice vlan id 20
You should ensure CDP and/or LLDP are enabled as well. I would check this in web GUI. DHCP for the phones can come from the switch, a DHCP server on a VLAN20 access port or you can use dhcp helper to redirect DHCP to server elsewhere.
If you prefer or have issues with CDP or LLDP you can also program ports as trunks and add tagged VLAN 20 to them. In this scenario you need to insure inter-vlan routing is working and that phones download config file with corrrect VLAN config.
These switches do not run ios so they are similar but different than catalyst switches you referred to.

Passing voice and data Vlans on Cisco SG200-08P help

Hello All,
I'm struggling with a configuration issue on the Cisco SG200-08P.
We are using the Cisco SG200-08P on a mobile cart that will go from class room to class room that will have computer and cisco Voip phone plugged into it. The issue is that each of our closets are in differnt VLANS ( 1 voice and 1 data....lets say data vlan 20 and voice vlan 2025 for conversation) and that we route to each closet.
It would be great if I could just create a generic data and voice vlan to dynamically pick up what the upstream switch has however, it seems that I've been unsuccessful in doing so.
So far I can pass the data Vlan no probablem. The upstream switch port is set to access port and a switch port access voice vlan (these are 3750x switches)
If the above is not possible I guess I will take what I can get. Should I just create data vlan 20 and voice vlan2025 on the Cisco SG200-08P and make a trunk port on the Cisco SG200-08P and a trunk on the 3750x? Is there an option on the Cisco SG200-08P to tag voice traffic?
I'm also concerned with VTP and I did not see an area in the Cisco SG200-08P to set that as a client and transparent mode.
Thanks for any help,
Dan

On a Catalyst switch, when a port is defined as a trunk without a vlan specified on the port, all vlan pass through the port. On a small business switch it is nearly the opposite. You must specify the vlans on the links. Additionally, ingress filter discards anything not associated to the port.
802.1q specifies there must be an untagged vlan which is the native vlan (of course you can make exceptions, tagging the default vlan..).
One thing I did in the past with a 2960, I made an LLDP network policy and it basically "provisioned" the downstream switch connecting link and voice vlan. That may be another idea for you.
Here's a link that may be useful-

Inter-VLAN routing, Auto-Voice VLAN and IP Address-Helper

Hope that somebody can help me with the setup in the screenshot.
Planning to use Auto-Voice VLAN and Smartports to configure VOIP
LLDP-MED will be enabled on the switch to detect the IP phones so they will be moved to the Voice VLAN (If not the first 6 signs will be added to the OID table). The Voice VLAN ID will be 2 >> Voice VLAN will be automatically enabled once a device is recognized as a IP phone right?
Workstations will be connected to the Cisco switch, VLAN data will be untagged and will remain on the native VLAN.
Smartports will be used to configure the ports (Macro's) >> Should configure the ports as trunks as assigns the correct VLANs right?
But how do i configure the IP Helper-Address? Do i have to create the Voice VLAN on both switches and then run the command "IP Helper Address" to specify a DHCP server? From what i've been reading it's required, when using Inter-VLAN routing, to configure the VLAN interface with an IP address. But it's going to give problems when both switches are connected to eachother and both have the same VLAN configured including the same IP address assigned to their VLAN interface?
Normal data should pass the ASA firewall, VOIP traffic should go through the Vigor modem to a hosted VOIP provider. The best way, i assume, is to configure 2 separate scopes on the DHCP server?
Still confused on how to set it up, hope that someone can point me in the right direction

If you're sending voice to only the Vigor modem then there is no need for a trunk between the SF-300 and the Vigor modem. You can just set that to an untag packet for the VLAN 2 between that switch and the Vigor modem.
On the 'edge' SF300 where the IP phone/PC is it is obviously going to interoute there and of course the phone port is tagged and PC port is untagged.
For the IP helper, it uses UDP-RELAY and it should be enabled on the port itself and enabled on the global configuration. You may also need option 82. Also keep in mind, depending how your DHCP server works, it may need option 82 configured as well or at least a route to understand the subnets in the layer 3 environment to get traffic across the VLANS.

Vlans, voice and data

I am implementing voip, we want to plug the pc into the phone and make both see the network but yet they are on different vlans, how does the port know which data is for voice and what data is for the pc ? do you enable the port to see both vlans by the swithport mode command, or does the port only go into 1 vlan ? At the moment we have vlan 200 and vlan 1, We have just plugged the phones in vlan 200 and pc's in vlan 1 but at the moment they are in seperate ports, I want to know what we will have to to when we plug both phone and pc into one port ?
thanks
Carlos
thanks

Hi Carl,
Nops not at all this is not the normal way to configure ip phone and pc together to a switchport. Infact on switches with current code and mostaly all the switches you cannot configure 2 dats vlan on same port like you are doing now.
If you give switchport voice vlan 200 and switch port access vlan 1 then they are 2 different kind of vlans and will work on same port.
Now when you give switchport access vlan 1 means there will be no tag and it is justa frame without any tagging and saying it belongs to vlan 1 as as it reaches the switchport it gets pvid of vlan 1.
When you configure switchport voice vlan 200 it will be a tagged vlan. Because ip phones are switches itlsef as soon as you give voice vlan command it will form an internal trunk and start sending voice data on tagged with vlan 200 and switchport will understand that tagged traffic and will come to know it is for vlan 200 and voice traffic,

I have a BE6000 server, is it possible for me to make it do a DHCP for both voice and data? Kindly guide me through. Thanks

CUCM can perform DHCP functions, but it's not meant to replace this functionality from a router or switch, which are the most common places to configure DHCP.
I assume you'll have at least one of those, why not configure it there??

Use WRP400 (VoIP Router) for Voice only, and the rest with WRT54GL

Hey there, I hope you are doing great!
The reason of this thread is because I recently moved to a cable ISP and unfortunately had to also change routers in order to take advantage of the VoIP feature (analog phone) they provided me with.
Now, the new router, the WRP400, is very limited feature-wise compared to the custom flashed WRT54GL I used to use with my DSL provider.
Now the WRT54GL does not have any FXS ports, so I obviously can't just plug my cable modem to the WRT54GL. Therefore, I was hoping to achieve a setup similar to this one:
Cable modem => VoIP Router w/ voice only (WRP400) => "Main" router (WRT54GL w/ Tomato)
Is there a way to bridge the WRP400 successfully with the WRT54GL keeping only the voice feature enabled on the VoIP router while the WRT54GL takes care of the rest? (Wireless, WAN, port forwarding, etc)
Thank you very much for your help, and have an awesome day!
Lev

I am going to provide a few snapshots of the config pages as to make this easier:
