There is no "Switchport Voice Vlan" command on SF300-24P !!!

Hello everyone
I am in an urgent problem :S
I have a Small Business SF300-24P
I have created two vlans one data and one voice
but i have not assigned them to the ports and I am not sure how to do so since there's no "switchport voice vlan" command under the interface !!
here are the configurations
btw the switchport mode is still trunk as it is by default
Thanks in advance

Hi Sandy,
You need:
switchxxxxxx(config)# voice vlan id 20
and smart ports should do the rest.
for your reference: http://www.cisco.com/c/dam/en/us/td/docs/switches/lan/csbms/sf30x_sg30x/administration_guide/CLI_300.pdf?mdfid=283019666

Applying command switchport voice vlan

Hi everyone,
At customer setup they have implemented VOIP and as they have to meet the deadlines for this project and they are in rush they want all the switch ports where users are connected should be configured for voice vlan.
As we have server,printers and other devices also connected to these switches.
if i configure int range fa0/1 - 48 with voice vlan command will it cause any issue to devices connected to the switch other than user PC?
Regards
MAhesh

Any issues to ports w/o a VoIP phone but configured with a voice VLAN? Well, broadcast traffic on the VoIP VLAN will go to each port configured with a voice VLAN, but on a VoIP VLAN I wouldn't expect there to be too much of this traffic. So it shouldn't be significant.

Switchport voice vlan : untagged / none / dot1p

Hope anyone can shed light on this.
When "switchport voice vlan <keyword>" is configured, a Cisco IP Phone will be instructed via CDP how to deal with voice frames. According to CCNP BCMSN Official Certification Guide, a diagram suggests that when using "untagged" as keyword, IP Phone will use a Special 802.1Q trunk case so that 802.1p bits can be set. It also shows a table which seems to contradict the diagram as the CoS bits column indicates no 802.1p bits are set.
So, can any one tell me the difference in terms of 802.1Q, 802.1p, and native vlan how each mode:untagged/dot1p goes about?
My understanding is that with dot1p IP Phone will use 802.1Q using VLAN 0 (null or "native" vlan) merely for frames to be prioritized using 802.1p bits. As for "untagged" mode, I read somewhere that IP Phone would also use 802.1Q vlanid=1025, again, just for 802.1p bits to be set. But "untagged" seems to me like "none" when it comes to how the IP PHone will forward its voice frames.
Thank you!

My understanding is the following:
with dot1Q - it will trunk using dot1q encapsulation
with dot1p - it will use ISL encapsulation
with untagged - native VLAN configured on the port.
This is how it works:
This is how PC at the back of IP Phone works:
Once native is configured switch will communicate with PC with no vlan tags but will add NATIVE VLAN TAG when packets are forwarded to the LAN. SO when you configure NATIVE VLAN - this is the VLAN that switch add the tag into packets.
At the same time once tagged packets with NATIVE VLAN arrive to switch port destined to PC, switch will remove trunking enxapsulation (otherwise packets will be discarded by PC) and will send packets to PC
Similar rule is applicable to IP Phone.

Vakhtang

[Prime infrastructure 2] Switchport voice vlan

Hello,
A device in Device Work Center > Feature Configuration > interface does not show up its voice vlan configuration.
Likewise, in EDIT mode, there is nothing related to voice vlan config.
Is this normal ?
Regards.
V.

As to get the VLAN information, the file in Cisco devices Flash : Vlan.dat is fetced, and if PI fails to do so, it gives this error. As it is a file in flash, PI needs to send it over to Server itself using TFTP.
If TFPT is somehow not working between Server and devices, it may throw this error.
Is it happening with all the devices or some perticular platform?
If with all the device, you need to check if there is any Firewall blocking TFTP access to devices.
Also, you can check if TFTP service on CPI is working properly by command ncs status.
If service is affected, try to restart service - service tftp restart Or you can restart the PI Machine itself.
-Thanks

802.1x and Voice VLAN

I had read articles on cco, and I believed for the same switch port we can have 802.1x configure and the voice vlan configure. It mean the IP phone is connect to the switch port with 802.1x configured, but the phone will not autheticate, only the workstation connect to phone data port will get authenticate.
I had configured 802.1x and test with notebook logon and able to access the network. Now I would like to test the notebook attached to IP phone data port, and the phone connect to switch port configure with 802.1x. But I failed to add voice vlan commmand. Why ?
interface GigabitEthernet9/48
description temporary port
switchport
switchport access vlan 12
switchport mode access
no ip address
dot1x port-control auto
spanning-tree portfast
CIG01-ENT-SW1(config-if)#switchport voice vlan 14
Command rejected: Gi9/48 is Dot1x enabled port.

Using IEEE 802.1x Authentication with Voice VLAN Ports
A voice VLAN port is a special access port associated with two VLAN identifiers:
?VVID to carry voice traffic to and from the IP phone. The VVID is used to configure the IP phone connected to the port.
?PVID to carry the data traffic to and from the workstation connected to the switch through the IP phone. The PVID is the native VLAN of the port.
In single-host mode, only the IP phone is allowed on the voice VLAN. In multiple-hosts mode, additional clients can send traffic on the voice VLAN after a supplicant is authenticated on the PVID. When multiple-hosts mode is enabled, the supplicant authentication affects both the PVID and the VVID.
A voice VLAN port becomes active when there is a link, and the device MAC address appears after the first CDP message from the IP phone. Cisco IP phones do not relay CDP messages from other devices. As a result, if several Cisco IP phones are connected in series, the switch recognizes only the one directly connected to it. When IEEE 802.1x authentication is enabled on a voice VLAN port, the switch drops packets from unrecognized Cisco IP phones more than one hop away.
When IEEE 802.1x authentication is enabled on a port, you cannot configure a port VLAN that is equal to a voice VLAN.
Waht kind of switch do you have? In 3550 I can configure the port for both vvid and pvid:
interface FastEthernet0/1
switchport access vlan 3
switchport mode access
switchport voice vlan 2
no ip address
dot1x port-control auto
spanning-tree portfast
end
Nevertheless, as the statement above indicates, the port will need to be configured for multi-host in order the PC behind the phone get autehntication:
under the interface configure "dot1x host-mode multi-host"
Nevermind, I just realized that you might have a 5600 running native, checking the configuration guide and realese notes it does not looks like dot1x and vvlan can play together in that platform.

Cat 3750 with Voice VLAN and Dynamic VLANs

Morning,
Has anyone had any success with configuring a Catalyst 3750 with a Voice VLAN (Cisco phones) and 802.1x dynamic VLANs?
Is a RADIUS server able to provide values to change the native vlan?
Is there a decent tech note knocking about for configuring 'dynamic VLAN assignment through MAC addresses'?
Thanks,

Voice VLAN's don't require trunk ports to be configured (unless you are talkling about 2900XL/3500XL switches). Cisco added the ability to trunk a single 802.1q VLAN down an access port in addition to the access vlan - so in 2950 or above the only config you need is:
interface FastEthernet0/1
switchport
switchport mode access
switchport access vlan 10
switchport voice vlan 100
This is effectively the same as:
interface FastEthernet0/1
switchport
switchport trunk encapsulation dot1q
switchport mode trunk
switchport trunk native vlan 10
switchport trunk allowed vlan 10,100
The only difference is the CDP message with the first config will advertise the Voice VLAN capability and the tag.
With the older 2900XL/3500XL switches you had to configure the interfaces like the second example (plus adding the command switchport voice vlan xx for CDP to inform the IP Phone of the voice vlan).
QoS is not detailed anywhere here and that obviously plays an important role with voice.
In your scenario I am not sure ACS can do what you describe as this will require 802.1x supplicants on the client PC's (I may be wrong here and I do remember someone talking about switches being able to do an 802.1x 'proxy' using the MAC address on behalf of non 802.1x capable devices). This seems to me more of a VMPS application.
Personally I would reconfigure the network each time and charge the occupants a small fee for network setup.....

SRW224G4P : voice vlan problem

Hi guys ,
i've a problem with tagged vlan with my SRW224G4P.
I,ve got following scenario:
one cisco 2801-CCME/k9 router
one cisco small business SRW224G4P layer 2 managed switch
ten cisco IP phone 7940 and 7931
ten personal computer
I need to use the embedded switch on the phone to connect computer . I need to
have 2 separated vlan for data and voice traffic.
I configured srw224g4p first 12 ports as follows
interface ethernet 1/x
switchport allowed vlan add 199 untagged
switchport native vlan 199
switchport allowed vlan remove 1
switchport mode hybrid
switchport allowed vlan add 150 tagged
spanning-tree cost 100000
spanning-tree edge-port
where vlan 199 is for data and vlan 150 is for voice .
I set following dhcp pool on 2801
ip dhcp pool phones
network 192.168.150.0 255.255.255.0
default-router 192.168.150.1
domain-name cmedeis.local
option 150 ip 192.168.150.1
ip dhcp pool PC
network 192.168.199.0 255.255.255.0
default-router 1982.168.199.1
and configured router on a stick as follows
interface FastEthernet0/0.150
description CME interface
encapsulation dot1Q 150
ip address 192.168.150.1 255.255.255.0
interface FastEthernet0/0.199
encapsulation dot1Q 199
ip address 192.168.199.1 255.255.255.0
My problem is that phones connected to the switch ports doesn't recognize tagged
traffic and doesn't take ip of the corrected dhcp pool of 150 vlan.
With a cisco 2960 poe switch i configured switchport voice vlan 150 and
switchport access vlan 199 and all is fine but this small business switch don't
handle switchport voice attribute and i can't separate voice and data vlan .
Someone have idea how to avoid this problem?
Need some help , please.
Bye

Good posts as always Christopher!
As Christopher mentions you will need to hard code the voice vlan on all of the phones. The phones will send the voice traffic via this vlan, and the PCs will send untagged traffic.
I hope you do not mind a tangent and I hope this is not too great of a distraction, but the thought of QoS and security came to my mind as I read this post.
Besides the vlan problems, which I am sure we can get through, there is also a concern.
Any chance you would consider a 3560 for this deployment? You have quite a few Cisco phones, a Cisco router, and many PCs. The Cisco switch would give you CDP, which would be useful for the voice vlan and power settings, as well as the important automatic QoS and security settings.
On my 3560, I applied a smart port macro. A smart port macro is a series of best practices / command sets put into a simple to use command. The one I applied is called cisco-phone. Here is the output before and after:
c3560(config)#do sho run int f0/18
interface FastEthernet0/18
end
c3560(config)#int f0/18
c3560(config-if)#macr app cisco-phone
c3560(config-if)#sw voice vlan 5
c3560(config-if)#sw ac vl 1
c3560(config-if)#do sho run int f0/18
interface FastEthernet0/18
switchport mode access
switchport voice vlan 5
switchport port-security maximum 2
switchport port-security
switchport port-security aging time 2
switchport port-security violation restrict
switchport port-security aging type inactivity
srr-queue bandwidth share 10 10 60 20
srr-queue bandwidth shape 10 0 0 0
mls qos trust device cisco-phone
mls qos trust cos
macro description cisco-phone
auto qos voip cisco-phone
spanning-tree portfast
spanning-tree bpduguard enable
end
The switch automatically globally enabled mls qos and configured the many class-maps, policy-maps, and applied them all accordingly. As you know, it is important to establish the trust boundaries when doing voice and QoS. These switches also uses SRR which is a very good way of applying shaping.
Does this help? I hope so. Please fire back any thoughts or questions you may have.

802.1x / dot1x Authentication, including Voice-Vlan and Guest-Vlan

Hello,
i have tried to configure a dot1x based Authentication.
With an single host including guest-vlan, everything works fine.
But i want to use an IP-Phone (wich is every times authenticated) and behind the Phone an Client.
Is there a possible solution? And unfortunately IP-Phones are Avaya-Phones.
i have just tried so...
interface GigabitEthernet0/4
switchport access vlan 121
switchport mode access
switchport voice vlan 200
authentication event fail action authorize vlan 99
authentication event server dead action authorize vlan 121
authentication event server alive action reinitialize
authentication host-mode multi-host
authentication order dot1x
authentication port-control auto
authentication periodic
authentication violation restrict
dot1x pae authenticator
dot1x timeout quiet-period 10
dot1x timeout tx-period 1
spanning-tree portfast
Thanks, for any possible solution!

unfortunately because they are Avaya phones, the easy answer CDP-Bypass fails in this instance. When you plug in the phone, the switch will assume it's the 'single host' for this port, and restrict the port due to the authentication for the phone failing. Maybe you can just hard-code the voice-vlans on each phone, but that could get tedious depending on the amount of phones.
I believe there is a DHCP option you can pass back that indicates the phone should be running on vlan 200, but for this to work you'd also need to set up a pre-auth ACL that would allow DHCP to work in the unauthorized state. I think it's 147 off the top of my head.
Another solution (which isn't what you originally wanted, but it would work) is to just use multi-domain instead of single-host, and authenticate both the phone and the PC. The raduis server should be able to distinguish between what is configured as a phone and what is a host, and will send back the appropriate vlan if configured correctly.
What are using for a radius server?

Phone 7961 solution without implementing "switchport voice" immediately at switch port

Is there any
Phone 7961 solution without implementing "switchport voice" immediately at switch port but at the switch before the switch which is directly connected to the phone?
(Please see attached diagram. )

No. "switchport voice vlan" works only if configured on the swtch directly connected to the phone.

Dude, look at your DHCP exclude on your router.
It is supposed to be low/high IP.
So basicly you told the router to exclude IP address from 10.146.54.1 to 10.146.89.5.
This means that DHCP will not hand out 10.146.54.1 through 10.146.89.5
try
ip dhcp excluded-address 10.146.54.1 10.146.54.15
Hope this helps.
Also, I know this is years ago but thought I would throw that out there.

Problen Creating Voice VLAN on 2800

Added VLANs to vlan database. Created separate VLAN i/f for voice (vlan12) and data (vlan7)on 2800 w/ip addresses.
[sh ip int brief]: vlan 7 is up&up, vlan12 is up&down.
On fa0/0/1:
interface FastEthernet0/1/0
switchport access vlan 7
switchport voice vlan 12
spanning-tree portfast
Cannot bring vlan12 to up&up.

Hi,
For vlan12 to be up/up, there needs to be at least one interface in that vlan that is up/up.
Secondly, fa0/0/1 has a small misconfiguration that may be related. You need to configure the interface explicitly as a trunk on etherswitch modules. This is similar to the 2900/3500XL switches, and different from the 2950/3550/3750 switches.
See:
http://www.cisco.com/en/US/products/sw/iosswrel/ps5207/products_feature_guide09186a00802c6bb6.html#wp1049866
An example config would look like:
interface FastEthernet0/1/0
switchport access vlan 7
switchport mode trunk
switchport voice vlan 12
spanning-tree portfast

Cisco Layer 3, Voice, & VLAN

I have a vSphere 5.5 install and I'm in the process of a network upgrade in preparation for a VOIP implementation. The Switch hardware I'm using is a stack of Cisco 3850 Layer 3 switches and I've been going in circles on getting vlan traffic to work correctly. Hopefully someone can point me in the right direction.
I have one NIC connected to the switch (10GB fiber) that will handle all traffic for the esxi host (except for management). VLAN ID is set to None (0) and load balancing is set to Route based on originating virtual port.
I have 2 subnets, 10.1.0.0/16 (data & management, VLAN 1) and 10.10.1.0/24 (Voice, VLAN 10)
On the host I have a Win 2012 R2 server that will be a VOIP PBX host. It must be able to communicate with the IP phones (VLAN 10) and other servers (VLAN 1).
The switches will do the intervlan routing.
Finally my question - Can anyone give me some hints on how to set up the interface on the Cisco for the 10GB fiber connection from my host? Actual port settings would be extremely helpful. Anything I'm doing at the vmware end that I should be doing differently?

In case anyone comes across this in a search, here's what I ended up with, 1st the Cisco switch:
switchport trunk allowed vlan 1,10
switchport mode trunk
switchport nonegotiate
switchport voice vlan 10
macro description cisco-switch
spanning-tree portfast
spanning-tree link-type point-to-point
The virtual switch I set to all vlan IDs and Route based on originating virtual port.

Cisco voice vlans w/ nortel VOIP system

Hello everyone,
I am going to segment a network with a Nortel VOIP system. Right now, the network is completely flat with PCs plugged into the back of the nortel phones. I would like to set up a voice vlan for the nortel phones but am not sure if voice vlans will work w/ non-cisco phones (cdp). Please provide me some insight if you can. Thanks!

If your are Using Recent Cisco Switches it is quite easy.
Using 4006 SUP III core switches or 3560 PSE's should be okay.
If you have Nortel Phase II phones they can also be powered by the 802.3 cisco switches with no probs.
Anyway set the switchport mode to switchport voice vlan. Set spanning tree portfast and configure qos as you see fit on the port. Configure the voice vlan on the switch eg switchport voice vlan 111. You may need to configure the port to switchport mode dynamic desriable as well. Some older switches may have problems but you can enable trunking to cheat and then a default vlan for the pc on the switchport
As regards to the phones when the phone reboots and you enter the configuration mode via flipping the 4 soft keys. You should then see the vlan option and configure the same vlan number on the phone as the cisco switch eg 111.
The phone should then register again without any problems. All i2002/i2004 firmware for last 2 years has the vlan option. I looked after about 400 nortel phones all on cisco switches of various ages with only minor setting up issues.

Window DHCP Server is not allocting IP to Voice Vlan

Hi,
I HAVE 3560 Switch, Over that two vlan configure Data & Voice respectively. Voice id Vlan 1 and Data Id Vlan 2.Routing is done on this switch and work as L3
DHCP Server is member of Data Vlan which is connected to another 3560 Switch L2. DHCP Server is reachable.On that both vlan configured.
Switch Port configure fr both Vlan ( Switchport access vlan 2 , Switchport voice vlan 1, Switchport mode access)
WHILE Connect any pc to port DHCP server assign ip frm Data Pool while Cisco Ip phones are not getting IP. OPTION 150 is configured in DHCP.
Over both interface IP Helper is configured and pointing to DHCP Server.
For testing point configure DHCP service on switch with voice pool range ;at that moment Cisco IP phone got the IP fron switch DHCP.
Now not able to understand why window dhcp server not assigning ip for Voice.
Both Vlan are in different subnet and having / 24.
Please guide

Hi,
Checked all configuration in network,apply packet tracer and found DHCP not responding on DHCP Req.
Replace DHCP server and now working fine. :)

There is no "Switchport Voice Vlan" command on SF300-24P !!!
