Connect 2 phones to one switch port

Could anyone tell me if it is possible to connect two phones (7911 and 7940) on the same switch port(2950)?
Thank you

it will work. just remember that both phones will share that port. Plug another switch into the 2950 port and put both phones in the new switch.
Or plug 7940 into the 2950 (powered locally using power cord). Daisy chain the 7940 to the 7911 using a cross cable. (7911 powered locally using power cord)
Again these type of connections are not recommended.

Two VLANs on one switch port?

Currently we have the following
Cat 4003 with VLAN trunking turned on to multiple switches. Each port in those exterior switches is assigned to a vlan(we have about 60 different vlans).
What I would like to do is on those exterior switches have two vlans assigned to it.
We'd like to create a single IP Phone VLAN(let's call it 999) that can span our entire enterprise and would have dhcp deployed on it.
Each port is connected to an IP phone which has a 2 port switch in them. One port to the wall, one to the pc.
The switch ports on those phones support vlan tagging
How would setup an exterior switch to access 2 vlans that connect to 2 port switch on an IP phone?

To facilitate ease of deployment, use VTP so that you can centrally create the vlans and propagate to each exterior switch. Now I believe you already do have a layer 3 engine or router that does routing between all these vlans. What switches are used on teh exterior ? This is to find out if voice vlan support is available.
In cat switches, voice vlan is created using command,
set port auxiliaryvlan vlan
In IOS based switches,
int fa0/1
switchport mode trunk
switchport trunk encap dot1q
switchport trunk native vlan
switchport voice vlan
switchport priority cos extend 0
or
int fa0/1
switchport mode access
switchport access vlan
switchport voice vlan
I am not sure about support of voice/aux vlan in 4003. We will have check your other switch models/ software versions to determine support for this command.

Find IP address/machine connected to a cisco switch port

hello,
I need to know which IP/device is connecetd to a cisco Switch port.
I can get the mac-address of that switch port using sh mac-add command, but with the mac address how can i find that which ip belongs to this mac.
is there way i can do this, i know i can do the other way meaning with IP i can find to which port its connected ,but dont know how to find this MAC to IP with switch without the need for additional tools

Hey Anantha ,
Hop u r doing good,
If u dont know ip address of devices present on specific vlan and wanted to track end device ip address please try
follow this below
steps 1:ping it to brodcast ip address of subnet
for ex
R1--SW1--SW2--(H1
                             --H2
R1..1.1.1.1/24
H1..1.1.1.2/24
H2.1.1.1.3/24
So u r brodacast ip is 1.1.1.255
ping 1.1.1.255
Sending 1000, 100-byte ICMP Echos to 1.1.1.255, timeout is 2 seconds:
Reply to request 8 from 1.1.1.2, 28 ms
Reply to request 9 from 1.1.1.3, 64 ms
u will get reply from all host present on that segment and ur arp table will get flood with ip and respective mac on
your L3 device...(R1 in this example)
Step2: then u can use command
sh ip arp ..to see ip and respective mac associate with it
R1#sh ip arp
Protocol Address          Age (min) Hardware Addr   Type   Interface
Internet 1.1.1.1                 -   c000.2498.0000 ARPA   Vlan2
Internet 1.1.1.2                 0   c003.2498.0000 ARPA   Vlan2
Step3: see the mac learned from specific port
R1#sh mac address c003.2498.0000
Destination Address Address Type VLAN Destination Port
c003.2498.0000          Dynamic       2     FastEthernet1/1
Step4:If u have all cisco devices then u can use CDP
to check wht device connect to ur interface
R1#sh cdp ne fa1/1 detail
Device ID: SW1.lab.local
Follow this way, hop u will trace devices present on ur network
Hop this informative,

How to provide access to multiple users connected to a Dumb switch? (multi-auth/multi-domain)

Good morning everybody,
I am writing on behalf of not being able to implement a desired outcome in our company network. In fact the situation is as follows:
What I want to do is to be able to authenticate users (802.1x authentication) in our company radius server and authorize them access by having a dynamic VLAN assignment in a multi-user environment on one and the same port of a Cisco 2960 switch. So far, the authentication and authorization has been working completely smoothly (there are no problems with itself). The concept involves the configuration of both DATA and VOICE VLANs as I there is also phone authentication implemented. In order to simulate this environment I introduce a Dumb switch connected to my Cisco 2960 Catalyst.
What I have successfully managed to get to work so far is this:
1) On one switch port I have tried the “authentication host-mode multi-domain” and it worked perfectly for a PC behind a telephone, or with one PC connected to a the dumb switch + the telephone connected to another port of the dumb switch. Logically it is the same situation as there is a separation in two domains – DATA and VOICE. Bellow is an output from show authentication sessions for this scenario.
Interface MAC Address Method Domain Status Session ID
Fa0/23 0021.9b62.b79b dot1x DATA Authz Success C0A8FF69000000F3008E (user1)
Fa0/23 0015.655c.b912 dot1x VOICE Authz Success C0A8FF69000000F9009F (phone)
2) On the other hand, when I try the same scenario with the “authentication host-mode multi-auth”, the switch still separates the traffic in two domains and is able to authenticate all users, AS LONG AS they are in the same VLAN.
show authentication sessions:
Interface MAC Address Method Domain Status Session ID
Fa0/23 0021.9b62.b79b dot1x DATA Authz Success C0A8FF69000000F3008E (user1)
Fa0/23 b888.e3eb.ebac dot1x DATA Authz Success C0A8FF69000000F8008C (user2)
Fa0/23 0015.655c.b912 dot1x VOICE Authz Success C0A8FF69000000F9009F (phone)
However, I cannot succeed authentication of many users from DIFFERENT VLANs, neither in multi-auth nor in multi-domain modes.
What I want to get is an output like this:
Interface MAC Address Method Domain Status Session ID
Fa0/23 0021.9b62.b79b dot1x DATA Authz Success C0A8FF69000000F3008E (user1)
Fa0/23 b888.e3eb.ebac dot1x DATA Authz Success C0A8FF69000000F8008C (user2)
Fa0/23 0015.655c.b912 dot1x VOICE Authz Success C0A8FF69000000F9009F (phone)
I want the switch to authenticate the users anytime they connect to itself and for them to have an instant access to the network. (I tell this because I tried scenario 1) with multi-domain mode and authentication violation replace, and it worked but, two users never had access to the “Internet” simultaneously!!!
The configuration of the interface connected to the Dumb switch is as follows.
interface FastEthernet0/x
description Connection to DUMBswitch
switchport mode access
switchport voice vlan XXX
switchport port-security maximum 10
switchport port-security
switchport port-security violation protect
authentication host-mode multi-auth
authentication priority dot1x
authentication port-control auto
authentication timer reauthenticate 4000
authentication violation replace
dot1x pae authenticator
dot1x timeout tx-period 10
spanning-tree portfast
The way I see it is explained in the following steps:
- PC1 connects to the Dumb switch. This causes the Cisco switch to authenticate user1. This creates an auth. session with its MAC address linked to a domain DATA.
- When PC2 connects to the Dumb switch, this causes the violation replace which replaces the recent authenticated MAC address with the MAC of PC2. I would like it once authenticated to appear in the authentication sessions with a link to a new DATA domain linked to the VLAN assigned from the RADIUS server.
Is this possible? I think (in theory) this is the only way to provide authenticated access to multiple users connecting through Dumb switch to the network.
Has anybody ever succeeded in such a configuration example and if yes, I would be love to get some help in doing so?
Thank you
Stoimen Hristov

Hi Stoimen,
I have done a setup similar to yours with the only exception being VLAN assignment. When I used dACLs only, it makes things somewhat easier as the VLAN no longer matters. Remember that the switchport is in access mode and will only allow a single VLAN across it (with the exception of the voice VLAN). I think that is the real cause of your problem.
From what I can see, you have 2 options available to you:
1) Use dACLs instead of VLAN assignment. This means that an access list will be downloaded from the radius server straight to the authenticated user's session. I have tested this and it works perfectly. Just Google Cisco IBNS quick reference guide and look for the section that deals with Low Impact mode.
2) Get rid of the dumb switches and use managed switches throughout your network. Dumb switches will always be a point of weakness in your network because they have no intelligence to do advanced security features like port security, 802.1x, DHCP snooping, etc.
Hopefully someone else will chime in with another option.

HP 3800 switch port-security one mac in two VLAN for Cisco IP Phone

Hellow all!
I'm want use port-security for ports on my HP 3800. But PC connected
to network via PC port on Cisco ip phone. For phone used 10 voice VLAN,
for data - 1 VLAN (native). Cisco phone add self mac-address in these
two VLAN. On Cisco Switch 2960 i resolve this for 4 command:
switchport port-security maximum 3
switchport port-security mac-address pc_mac
switchport port-security mac-address ip_phone_mac
switchport port-security mac-address ip_phone_mac vlan voice
How i can add one mac in two VLAN's on HP 3800 Switch?
Sorry for my English, please ^_^

I will be using a HDMI cable to connect an Apple TV box and a Comcast cable TV box to my TV. My TV has only one HDMI port.

I will be using a HDMI cable to connect an Apple TV box and a Comcast cable TV box to my TV. My TV has only one HDMI port.
To do this I will need a 2x1 HDMI splitter or a 2x1 HDMI auto switch (preferred).
?Is there any Apple TV HDMI port voltage?
When using a HDMI auto switch to connect two devices to a HDMI TV, the
Auto switch cable box only works for components that do not output continuous voltage over HDMI port when turned off.
Do you know of any other solutions? Componets? Actual expierances?
Full text below.
Cable : HDMI switches expand the number of available HDMI ports on a high definition television allowing connection of cable boxes, Blu-ray players, and game consoles. A side benefit is that cable clutter is also eliminated by running a single HDMI cable to your HDTV from a switch and relocating the HDMI ports to a concealed location. The problem with most HDMI switches is that you have to either get up to push a button, or hunt for the remote control, to switch sources. The true mark of any great switching component is an ability to perform its function and remain transparent in its operation. This automatic HDMI switch is a plug-and-play away from offering everything you are looking for in an HDMI switch. Select a single output from up to three devices for signal delivery to your HDTV. Smart operation provides complete control for connect-and-forget operation. Powering on a device gives it output priority over the other devices. By powering down the device in use, output priority is returned to the last powered on device. Note: Auto switch function only works for components that do not output continuous voltage over HDMI port when turned off.

Hi Erico,
I tried what you said again but without success. I even updated the driver so that that audio driver is the same as the graphics driver i.e.. NVIDIA but this has not helped either:
Do you have any other ideas?

Failed while creating virtual Ethernet switch. Failed to connect Ethernet switch port

Hello Folks
I am completely stuck with the configuration of my virtual networks. I have one logical switch left to add to one of my Hyper-V 2012 R2 hosts when I started getting the error below when I try to add logical switches to either Hyper-V Host. I have been using
the document. 'Hybrid Cloud with NVGRE (Cloud OS)' to implement the virtual networking. Basically using the exact configuration that is in the document. I have added the PA Logical Network and the Network adapters and added the logical switch for it to my
hyper-v 2012 R2 host and everything was fine. I am now trying to add my ISCSI Logical Switch to the host and this is the error I get. My other Hyper-V host I get this error for any logical switch I am trying to add. Can someone help me with this error. I haven't
been able to find any information about it.
Also a some quick info on tracing an error like this so I can figure out what is causing it.
Thsi is my configuration so far
So as far as I know everything is peachy untill the error below. Dead stop now

notice your GUID? you may want to consider ensuring that is the same GUID associated in your database. Sometimes during data corruption theres a smidge of a chance your sql database kind of either pulls old guids esp if this was reverted to snapshot
without it being powered off etc.
I would try that first. then i would consider if you get to configure that with your current liscense associated with the host. I would need way more info to help any further

I have a mac book pro that both USB ports have stopped working one about a year ago and one recently. Is it possible to connect to another one of the other MBP's ports with a cord that ends with a USB port?

I have a mac book pro that both USB ports have stopped working one about a year ago and one recently. Is it possible to connect to another one of the other MBP's ports with a cord that ends with a USB port?

Thank you For your time and thoughts!
I went by the Apple Store and they told me that there was a "Flat Rate" repair service for this particular part where they would replace the logic board along with the USB ports for $350. Seems like best avenue. All of this would have been moot but my wifi in the computer also doesn't work so I was using my phone as a hot spot and tethering it to the computer for Internet access when the last port quit. This left me with no internet and no printing capabilities on the computer I use for my business. Basically became a nice paperweight. lol
They will ship it off Monday and I should have it back Thursday!
Again, thank you!

Connecting through an HDMI connector that has two HDMI inputs ports and one output port

I have an LCD TV with only one HDMI port which connects to the digital cable box. I bought a HDMI switching device, but have not been able to get the Apple TV to display on the TV. Has anyone encountered a similar problem?

AppleTV has always been fickle about HDMI connections - it is likely a compatability issue with the switch.
Presumably the other device connected works ok?

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.

Challenge: Spanning Tree Control Between 2 links from Switch DELL M6220 to 2 links towards 2 switches CISCO 3750 connected with an stack (behavior like one switch for redundancy)

Hello,
I have an Spanning tree problem when i conect 2 links from Switch DELL M6220 (there are blades to virtual machines too) to 2 links towards 2 switches CISCO 3750 connected with an stack (behavior like one switch for redundancy, with one IP of management)
In dell virtual machine is Spanning tree rapid stp, and in 3750 is Spanning tree mode pvst, cisco says that this is not important, only is longer time to create the tree.
I dont know but do you like this solutions i want to try on sunday?:
Could Spanning tree needs to work to send one native vlan to negociate the bdpus? switchport trunk native vlan 250
Is it better to put spanning-tree guard root in both 3750 in the ports to mitigate DELL to be root in Spanning Tree?
Is it better to put spanning- tree port-priority in the ports of Swicht Dell?
¿could you help me to control the root? ¿Do you think its better another solution? thanks!

Multiple interfaces connected to one switch. Sol8 OK, Sol10 NOT.

Hello,
finally we got our T5220s and I connected everything as it should be mirroring our V880 with four QFE cards.
I connected 14 gigabit ports to one switch and configured the interfaces.
On our Solaris 8 system on the v880 with the 15 connected qfe ports there were no problems.
Now on the Solaris 10 system, I can only configure one (1) interface and run packets to it. When I activate a second one, this is not seen from our application.
The application waits for multicasts and creates a connection based on port numbers.
I tried ip_forwarding per routeadm and directly on the interfaces. I reduced my interface to two. I can see traffic passing by the second interface, but the application does not.
What I can see, is, that there are some new attributes coming with Solaris 10:

What is blocking the communication?
Kind regards. Oliver

hi, perhaps you have to do some configuration with routeadm ? and enable ip_forwarding ? (man routeadm)

How do I add an airport extreme to a cable modem with only one ethernet port, while keeping that port connected to my Mac?

I have a mac pro connected by ethernet to a cable modem via ethernet. There is only one ethernet port on the modem.
I want to keep the Mac connected via ethernet for speed. Is there a way that I can add an airport extreme to this set up - for my ipad and roku, and for guests to use - or do I need to buy a router to put between the modem and the mac?
If I need a router, what kind?
Thanks.

The modem connects to the WAN "O" port on an AirPort Extreme router.
The Mac Pro connects to one of the three LAN <-> ports on the AirPort Extreme router.
Or if you do not need the ability to connect a hard drive to the USB port on the router, you can save a bit by using an AirPort Express.
The modem connects to the WAN "O" port, the Mac Pro connects to the LAN <-> port
Either the AirPort Extreme router or AirPort Express router will allow up to 50 wireless device to connect.
There are many other wireless modems offered by other manufacturers as well.
