We are facing problem with Cisco IP phones which are connected to module WS-X4248-RJ45V.Phones are getting restarted and sometimes phones will not take power.Initially we suspected issue with power consumption, but we have enough power in the module.
View 3 RepliesWe currently have around 150 2975 switches and have had problems with it them not handing out PoE power to the cisco phones and access points at random times. There is plenty of power left for the switch to use. We have at least 15 that will be running fine for about a week and then all of the devices that use PoE power will shut off and will not come back on until we reload the switch. If you console in there aren't any messages that pop up and if you look at the port it just shows on connected or will show IeeePD in the power inline. We have contacted Cisco TAC and they just RMA them.
View 6 Replies View RelatedI have two C4506 switches and I would like to create two L3 links between them by using only one physical link. I will then assign each L3 link to a different VRF.
I think I have two choices but I'm not sure however that the second one is possible...

1st choice: creating two VLANs and two SVIs on each switch

I have a 6500 chassis with 2 power supplies. At the moment I am using the default configuration:
power-redudancy mode redundant
The problem is that an inserted module is in "power deny" state due too insufficient power.
I know, that It's not a good idea to change into combined mode (loss of redundancy), but my customers requested this anyway.
So I will change to combined mode. So here's the 1 million dollar question: "Which modules will go into power deny, if one of my power supplies fails?"
The 6500 config guide states:
"Power supply is removed withredundancy disabled
• System log and syslog messages are generated.
• System power is decreased to the power capability of one supply.
• If there is not enough power for all previously powered-up modules, some modulesare powered down and marked as power-deny in the show power oper state field."
Well, do you know if there's any way to configure some kind of priority? E.g. I definetly don't want by 10Gig Module or WiSM module to be in power deny. Can i statically make sure, those module will be powered on for sure? Like: "power enable module slot_number" How is this calculated? Or is random?
In a stand alone 3750x switch configuration, can the secondary power supply only act as a redundant power supply (active/standby), or can it become a "pool" of power similar to power sharing mode for StackPower (somewhat active/active)? I understand there is no stack involved here but I'm curious if this functionality is possible.
View 1 Replies View RelatedI am working in Private IT company. The facility is having 4000 users and it is a high resliency site having two core switches and nearly 40 access switches. All core and access switches are 4506E switches and odd vlan is taking core-1 and even vlan is core-2. We are having cisco ip phones 6921 connected as daisy chain.( Phone is connected to access switch and the desktop is connected to ip phones). The Ip phone are getting registered cisco call maneger server. The call manager one leg is connected to one core switch and another one is core 2 same like my DHCP server.
For all vlans the the default gateway is my firwall. The voice needs to hit the call manager, hence we have implemented a source routing to call manager for the voice vlans. the problem is once we down the Core-1 some of the IP phones are not getting registered no matterit is on odd or even vlan. The same issue for Core-2. We suspect that there might be some issue in the DHCP server for voice vlan routing. But server team is saying that there is no issue with the DHCP server.Now network is vulnerable that if any core switch is down my voice ip phones will be down.
I have some Catalyst 3560 PoE switches running the latest 12.2(50)SE1 image. I have a working configuration for STP, QoS, Voice & Access VLANs, Port-Security & IGMP snooping - I stress this is working PERFECTLY. Now I have been playing with wired 802.1x port authentication for a while which again I have sucessfully deployed on ports without IP Phones. I did some more testing with 802.1x clients behind some Cisco IP Phones and after understanding the issues and workarounds I thought I had a working environment. The environment is XP SP3 with the new separate wired 802.1x supplicant, workstations are all in a 2003 AD Domain and the wired 802.1x settings are configured through group policy. I had issues with Windows Server 2003 SP2 not working behind IP Phones but this I put down to the supplicant being different from the new one in XP SP3. MS don't have any plans for Server 2003 SP3 (or XP x64 SP3?) nor can I find any hotfixes to resolve this so it's a 'caveat'.Anyway I have tested this many times and with XP SP3 and the new supplicant it all seems to work well (only the access VLAN is using 802.1x Authentication, I am not authenticating the IP Phones via 802.1x).
Now today it stopped working and 802.1x clients behind the 7970 IP Phones no longer authenticate. I have spent an hour or so looking at this and the IOS is the same, as is the configuration on the IAS (Radius) server, as are the XP clients. I was scratching my head a bit and then looked at the IP Phone - the software on the phone has been upgraded to 8.5(2) - previously it was 8.4(4). I managed tp downgrade the software via CUCM to 8.4(4) and it now works. I have retested it several times so this is obviously an issue (either a new feature or a bug?) with the latest code for the 7970. I have checked and it's the same codebase for all the latest IP Phones - 7906, 7911, 7931, 7941, 7942, 7945, 7961, 7962, 7965, 7970, 7971 & 7975 which was released on 1st June. I have looked through the release notes and EAP-FAST has been added but this is an update to the EAP supplicant on the phone and not a feature of the 802.1x pass-thru from the attached device. I can find no other 802.1x or EAP references.
I just installed a refurb'd 3560 48 port POE switch and configured all ports on VLAN100. All Polycom IP 430 phones (with power adapter and without power adapter) constantly reboot every couple minutes. Any Cisco 7960 phone does not constantly reboot and works correctly. When I plug a small unmanaged switch into a 3560 port and then plug the Polycom phone into the unmanaged switch powering the phone with a power adapter, the phone works correctly. So it seems that the 3560 is causing the Polycom to reboot.
View 3 Replies View RelatedI would like to know if there an specific configuration in order to apply QoS configuration in Switches 3750X for Polycoms Phones.I was reviewing the information from Cisco but mostly of them apply only for cisco phones, and just some or basic for non cisco phones.
View 1 Replies View RelatedI have a Catalyst 2960-S switch and a pre-standard IP Phone (Cisco 7960). When I connect the phone to the switch the switch recognizes the phone and supplies power. I would like to prevent this behaviour. ie. I would like to disable detection of pre-standard equipment. Is there a command I can issue on the 2960-S to do this? For example, on a switch from a different vendor I can issue the command: no power pre-std-detect to prevent it from detecting the 7960 phone, is there an equivalent command on the Catalyst 2960-S ?

View 0 Replies View RelatedWe are experiencing two of our layer 3 switches (3560 PoE and 3750 PoE) switches giving us problems with giving power to IP phones. These switches have an embedded PoE module and would previously give power to all IP phones on all its ports. Now all of a sudden over the past few months 6 of these ports have stopped powering phones. The phones are the same ie. 7911 and they take less than 15.4 W. We believe that the PoE module has started malfunctioning and has stopped giving power to all the ports. The port 'grants' power and then removes it. Below is a link showing all the messaged we receive on the terminal session. It is NOT a hardware fault with the PoE: [code]

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'm having some trouble with a 4510 Switch Line Card. I need some recomendations for troubleshooting it.We have some PoE phones connected to the card number 3. When those phones were restarted, they did not go up again. In order to discard wiring issues, we connected the phone directly to the card 3, and the phone did not go up. If the phone is connected to a different card, it goes up correctly.
Additionally, to restore the service, these phones were migrated to other cards, but when we disconnect the equipment, ports in line card 3 remain in an up / up state (and nothing is connected to those ports!!), and only reflect the actual state after restarting the port.What steps could I do in order to troubleshoot this issue?. What should I look for, or how do I discriminate the problem? Might it be a hardware issue, a PoE issue?
All of our VoIP phones bounced (re-registered) in the middle of the work day and we do not know why. There is no maintenance going on at this time. The phones came back up right away. Upon further investigation, I only found one error message on our core switch (WS-6509 running IOS ver. 12.2(18)SXF13) and I'm wondering if that was the cause:
