PoE works fine with C 1131/1141 Access Points and C-7975 IP phone but PoE does not seem to work on 7960 Phones nor on the C-1121 Access points
All devices work properly with the Cisco power injectors or on a Cisco Cat-29XX switch
Is there a trick to make PoE work for older devices ?
I have a Cisco 6500 which has two VLANs defined
VLAN 30 for Data VLAN
VLAN 31 for Voice VLAN
I have two Cisco 3750 switches.both switches are connected to IP Phones.the configuration of Cisco 6500 Trunk Port to Cisco 3750 is [code] On Cisco 3750, the trunk port to 6500 has the configuration [code].The IP Phones connected to the Cisco 3750 are 7911,7979, 7940, 7961.
All phone are working fine, the phones get their ip address from voice vlan, and systems connected to phones get from data vlan, except 7940/7960.
These two models of IP Phones remain on Configuring IP, and when you check the IP Settings, it gives Data VLAN IP, which does not have a TFTP.once you manually enter TFTP address in the field, it registers instantly, due to ip routing in the network.
these phones were working fine before, but suddenly few days back they went out of the network, and still are in Configuring IP state.I also tried to convert these ports connected to 7940/7960 to access ports [code] but still the IP is taken from the Access Vlan (30). Even If you configure a single VLAN on these ports, the IP phones then never get the IP.
I am looking into the possibility of using private vlan's for some dmz implementations however I do have what may be some very rudimentary questions. It seems straightforward how to configure the primary/secondary vlan configuration as well as associating them. However in my case I would be looking to configure the PVLAN on a 6500-vss platform acting as the router while all of the hosts which I would desire to have in the isolated vlan would be spread out across a number of older Cisco switches which only support "protected port" setup or Procurve switches all of which I do not have budget to replace with something newer. So in my scenario I would have a 6500 connected by trunk to multiple switches which only support a protected port setup such as a Procurve (top of rack) or a Cisco 2950. As the Procurve or 2950 would not support Private VLAN setup, do I then just configure the secondary vlan to be allowed across the trunk from the 6500, configure that vlan on the Procurve or 2950 (as vtp will not foward the info for the secondary vlan) and assign that vlan to the host port as well as setting it as a protected port and this will communicate just fine across the trunk to the router as well as stopping the protected port in top of rack switch 1 from being able to communicate to a protected port in top of rack 2,3,etc? If the above scenario is what needs to be done, do I just use a regular trunk or do I have to use a PVLAN trunk?
View 2 Replies View RelatedI have a new install with 3 SF300 switches, setup as vlan 2, the switch connected directly to the 2901 router has no problems, plug in a phone and it gets an IP, but if connected to either of the two swtiches behind the first switch, they do not get an IP. I am seeing the DHCP request hitting the router, and the router sending the IP to the phone, but it never gets the IP.

All ports are setup as trunk on vlan 2 including the ports that connect the switches together. Not sure what the problem is, but they are going live tomorrow and only have 48 out of 120 phones.
I want to connect a 6911 IP Phone to a SG 300 switch. This is my scenario: vlan 3 data, vlan 9 voice, vlan 10 admin.I have a trunk on port 10 of the SG 300 (vlan 1 untagged, vlan 3,9,10 tagged) and it is connected to a switch 3560, this switch has all the L3 configuration of the vlans and the SG 300 switch has an IP on the admin vlan (10).Also i added the OUI of my IP phones an created an LLDP Policy. Right now I have a 7941 IP Phone working but 6911 is not working. Iam using the new version 1.1.0.73 that supports CDP.
Also I noticed that even when my PC and IP phone receive IP address they can not ping each other nor the SG 300. They only can ping the default gateway or IP addresses in diferent vlans but connected on 3560 switch.
I have a question regard to switch SFE2010P, i have 2 vlan ( data and voice) and we want to configure Ip phones SPA502G, the question here is how can i make to suport 2 vlans on the same switch port, like the catalyst IOS switch port acces vlan x and switch port voice vlan x, if i set up the switch with the voice vlan like tagged doesn't work, but if i set up the voice vlan like untagged vlan its works but the PC attached to the data port on the SPA502G doesn't work?
View 1 Replies View RelatedI have 2 (and maybe soon 5 more) 7940G phones to add to my network, which already has a Netgear POE capable switch. I've since discovered that early Cisco POE isn't the same thing as current POE, and the switch doesn't power the phones.
I was looking at adding a Cisco SD208P 8-port switch to power the phones, but I soon discovered it only has 4 POE ports, and I'm not sure that this switch will even power the 7940G phones. And if the other 5 phones show up, I'll need two of those switches with no room for expansion on the voice network.
Will this switch power those phones?Is there another small switch available so I don't have to replace my existing switch infrastructure to get these phones to work? Or do I need to scrap the phones and get something newer that will work with the current POE standards?
i am looking at quoting the SF302-08P for a client which will have three small offices interconnected via single mode fiber. I am planning on connecting them to a 3560 switch. Each office will have no more than 3 - 7942 phones. I reviewed the notes on this switch and it seems it should support this phone type without any issues.
View 8 Replies View RelatedI have an ESW-500, a SPA525G (also tried 504G), Polycom IP330/670 phones, and a Switchvox (Asterisk-based IP-PBX) and CDP causes some issues.Both the SPA5xx and Polycom phones support CDP but it appears to operate differently between the phones. And, surprisingly, worst of all on the SPA's.
In short:
* Switch - CDP enabled (VLAN 100), DHCP disabled (Option 82 enabled) which is basically how it comes out of the box
* Polycom phones - CDP enabled (default)
* Cisco phones - CDP enabled (default)
* DHCP/TFTP server on port 1
* Phones on ports 7,15,19 - default as smartports for Desktop & Phone
* Switchvox on port 17 - port configured as General (not Trunk) with 1U & 100U VLANs. This was required to get Polycom phones to appear in Switchvox config
With that configuration the Polycom phones work perfectly. They appear in the switch web-GUI under CDP, they present in Switchvox and can be configured.But with that configuration although the Cisco phones appear in the CDP screen they do not get DHCP. My DHCP server can see 'DHCP Discover' messages but it just goes around in circles. Disabling CDP on the switch will allow the phone to get an IP but disabling CDP on the phone still has the same problem. When I saw "around in circles" this is what I mean....
Rcvd DHCP Discover Msg for IP 0.0.0.0, Mac 00:25:84:06:12:46 [10/08 13:51:27.031]

With the difference being there's a 'DHCP Inform Msg' which there never is from the Cisco.I have tried many options regarding DHCP Relay, DHCP Server addresses, DHCP VLAN Interfaces, smartport settings etc but with CDP enabled the Cisco phone just will not get DHCP.
According to the documentation, the Switches SFE2010P and SGE2010P have a maximun total power output of 360W. Using only SPA500 series IP Phones that have 10W maximun input, how many SPA500 IP Phones could be connected safely to this switches? 36 ? or 48 ?

This sounds like a routing issue to me. How to get AnyConnect clients to be able to reach each other?
I am trying to hook up a SF300 switch to a cable modem and then plug some phones into the switch that are configured with static IPs. I am able to access the switch without an issue, but need it to pass traffic from the phones to the network and it is not doing so. We cannot do trunking because we are not using BSoD modems yet (next phase). For now, we just need the switches to pass everything from the phones to the network as is. Any ideas?
View 4 Replies View RelatedI am having problem setting up SGE2000P switches to work with my default data VLAN and additional voice VLAN. I am configuring it to pick IP address for phones from voice VLAN which is working fine but when I connect a PC on phone port it is also picking up an IP from Voice VLAN while default VLAN is data with different scope of IP.
I pack these switches and purchase ESW 500 series. I have ESW 500 at another client and they are working fine out of the box but this guy is giving me hard time.
I am new to VLANs although I generally understand the concept. I have a small office with 25 desktop/laptops and 15 VoIP phones connected with a SG200-50 switch and on Port 1 I have the Cisco SRP541W router for DHCP and Internet access. My goal is simple: 1) Segregate the VoIP phones (voice) from the computers (data) and 2) Prioritize the VoIP phones traffic.
I believe this can be accomplished by setting up a second VLAN and maybe a third (if the default should not be used) and then identifying those ports as Voice VLAN ports. I guess I just need to know how to flag each interface and each port so that they all can talk to the router on Port 1 yet the voice and data will be in different broadcast domains. Also, do I need a management VLAN??
Is this setup correct? VLAN 1 - default (data) Port 1 (Trunk) (Tagged)Port 2 - 30 (Access) (Untagged)VLAN 2 - voice Port 1 (Trunk) (Tagged)Port 31 - 48 (Access) (Untagged) What should the interface settings be on each port (General, Access or Trunk)? What should the port VLAN membership be on each port (Tagged or Untagged)??
I have a small business SD208p P.O.E switch that will not power a 7960 VoIP phone over P.O.E. It currently is powering a 7965 VoIP phone and a WiFI access point. what's wrong? I have tried several different VoIP phone's & port combo's.
View 1 Replies View RelatedSo, I have a bit of a problem getting out Natted Cisco 7960 working with our external SIP providers behind NAT.
We have a block of IPs available to us, however when I asign a static NAT rule for the internal phone, outgoing calls are fine but incoming provides no audio.
We have no ACL blocking or anything, it's fully open to the outside world with the IP assigned to it via NAT.
Our static NAT rule for the phone:
ip nat inside source static 192.168.0.250 xxx.xxx.xxx.xxx
NAT is configured on the phone, with the external IP set correctly.
Also, after a while, it seems as the the registration times out or something because incoming calls no longer work.
I thought a static NAT rule would just allow full access to incoming connections to the internal IP specified? Our main router config (with unnecessary information removed):
version 15.1
no service pad
service timestamps debug datetime msec

Captcha is now gone (I read it was flawed anyway), and no option to turn it back on (I'd do anyway).So I'm looking for the older firmware that I was using for a year or so, which was 4.11. I found it and downgraded to it (actually, this was on another DIR615 rev.D), and guess what? No catpcha in that either!As far as I remember, I was using 4.11-B04 (but not sure, really), whatever it means, and now I only find 4.11-B02 everywhere.Is it possible that those FWs with buggy captcha have been removed from FTP servers worldwide?

I have some legacy (read: old) audio equipment that used leased lines to run, no way to convert them to IP internally. They have x.21 and v.35 interfaces on them.
Is there a way i could use something like an old 2600 series router and run it in reverse, like just using them as a media converter to shove the v.35 over into IP land?
I'm not interested in buying newest latest greatest (these audio codecs are upwards of $5k a pop to replace, x2 for a complete link), i'm just curious if i can turn a WIC-1T into the interface for these boxes and do a direct route to another 2600 on the other end with the same configuration.
This would essentially turn the WIC portion into the local side and the ethernet into the WAN side.
