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 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 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?
I 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.
I 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] DHCP: proposed address 192.168.100.16 [10/08 13:51:29.000] 4064 Request 2 not processed [10/08 13:51:29.062] Rcvd DHCP Discover Msg for IP 0.0.0.0, Mac 00:25:84:06:12:46 [10/08 13:51:30.093] DHCP: proposed address 192.168.100.16 [10/08 13:51:31.593] 4064 Request 2 not processed [10/08 13:51:31.656]
[code]....
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 ?
I have a CUCM BE environment with a number of remote users with 8961 phones connecting to an ASA 5501 via AnyConnect. The phones register fine and can make inbound/outbound calls as well as four digit dialing to other users at the corporate site.
The problem is when a remote user tries to four digit dial another remote phone. The called phone will ring but there is dead air once answered and then the line goes dead.
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?
I 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 7 POE switches that have ESI IP phones attached. I have two VLANS, 1 and 2. VLAN 2 is used for voice and is defined in each switch.The ESI IP phones connect to my POE switch ports and the pc attaches through the ESI IP phone.
I have had voice quality issue between floors in my building. Talking to others on my floor via the IP phone, there are no voice quality issues. [code]
We are using Linksys SRW248G4 in our network as Layer 2 Device. We have configured QoS policy for Voice and Video Priority over Data. On Layer 3 we are using CISCO SGE 2000, on that we have also configured QoS Policy and that is working, if we are connecting two IP Phones on L3 Switch but when we are connecting IP Phones on L2 Linksys we are not getting Voice and Video quality over Data.P2P link is of 10MB.I am Putting Whole configuration of that switch in TEXT FILE. [code]
We just purchased 8 managed switches POE to swap out our existing in preparation for our new phone system. We installed them all after configuring with static IP. Deployed... and all but two work fine. Any tips for troubleshooting why two of them do not work? There are a couple other switches in the building. Could it be that a switch "upstream" from the two non-functioning switches is causing an issue? If so, how do I find out? When we put back the two "dumb" switches all was fine.
We have two Web Servers and configured as Network Load Balancing in a cluster for failover.
WEB1 IP: 192.168.1.50 WEB2 IP: 192.168.1.51 Both configured with Cluster IP: 192.168.1.100 on Multicast mode.
TEST ON LAB USING ORDINARY 10/100 UNMANAGED SWITCH I can ping all the IP addresses on the LAN and when I http://192.168.1.110 on any PC on the LAN works no problem.
TEST ON PRODUCTION USING CISCO SG200 50/50 PORT SWITCH I can ping all the IP addresse on the LAN and when I http://192.168.1.110 on a different machine i did not work, but on the server itself will work as expected.
NOTE: Both tests are on LAN only.
I wonder if this is something to do with the switch because of Cluster IP MAC address. Do I need to configure something on the switch?
We have a single SGE2010 in layer 3 mode switch with a Server 2008 DHCP server.
We will be implimenting a Voip netowork where the PC's connect to the voip phone. I would like to create another vlan - 10. I have created the vlan and assigned the IP on the swtich.
Routing seems to be working. I can ping both IP addresses of the switch on either vlan.
I cannot get DHCP working. In the SGE switch I have enabled DHCP Relay, enabled option 82, set my DHCP Interface as VLan1, and specified the DHCP servers IP address. On the ports I have set the port where the DHCP server connects to as a trunk port with Vlan 1 untagged and vlan 10 tagged. I have set the ports where the phones connect as a trunk port with vlan1 untagged and vlan 10 tagged.
The modem Time Warner gave me several years ago was dying, I took it in, they gave me a Cisco modem, I plugged it into the computer, works fine, so then I plugged it into my airlink 101 wireless router, the computer recognizes the router but says there is no internet access, i.e. the modem and router are not communicating. Why would change of modem cause lack of communication with the router, is there something different about modems now compared with roughly 5 years ago? And what can i do to fix it so i can have wireless access again? If it matters, I have no protection on my wireless (because I never figured out how).
I am setting up a 3 host ESXi cluster. I am using a pair of stacked SG500-28 switches for switching redundancy. Each host has 8 NICs. 4 to each switch. I have successfully setup a 3 NIC LAG with 1 path to one switch and 2 paths to the other. These LAGs work. When I setup a 2NIC LAG via the console for management, and the associated ports on the switches, I lose managment communication with the host. Before setting up the LAG in the ESXi console, I set that vswitch properties to us IPHASH as instructed here bit.ly/VLaTEt I have attempted to follow those instructions as closely as possible. The one thing that I am wondering is whether the SG series supports etherchannel. I can't find any reference. Either way, it works on the other vswitch that is for vMotion. I can vmkping between the hosts over that LAG. But setting up a LAG on the management vSwitch doesn't?
We recently purchsed a SG200-26 and have several SPA303 with the 2 ports. The other component is a Sonicwall NSA3500.The SG200-26 is on an interface of the Sonicwall that interface has a primary of 172.20.3.x and the sub interface is 172.20.5.x. I labed the VLAN as 5?I went to the "Create VLAN" in the SG200-26 and also created VLAN 5 and under Voice VLAN the ID is 5.Then I went to the SmartPort and assigned GE24 as IP Phone + Desktop. That was OK. But when I go to the SPA303 and Enable VLAN and VLAN ID 5 I get Initializing Network. I am able to ping the 172.20.5.1 which is the gateway for the VLAN but still pull no IP. I also have an DHCP range assinged the subinterface.I also am using Cisco Configuration Assistant. I can see the switch SG200-26 and my IP set but it shows no IP. So I know that the CDP from the phone to the switch is working.
We just got many 3560x switches for a project. Curiously and in a very rate event (at least for me ) 4 of them died after workijg normally. 3 for some days and the last one for 3 weeks.Power supplies are ok and light up, they work on other switches, fans dont start kn the damagdd switch but work in ither switches.Syslog server doesnt show anything. It just goes puff. They are brand new switches biught one month ago from official channek distributor.
I setup switch in layer 3 mode. I have a access port in vlan 10 and a access port in vlan 20. I am able to ping form vlan 10 client to vlan20 default gateway (192.168.20.1) I am able to ping form vlan 20 client to vlan10 default gateway (192.168.10.1) However, I am unable to ping from vlan 10 to vlan 20 client. If both the ports are in same vlan, then clients are able to ping each other. Proxy Arp in enabled.
access-list <#> permit/deny <protocol> <sourceAddress> <sourceMask> <destinationAdd> <destinationMask>Say I applied an ACL inbound on Fa0/0, would the source address be the outside the LAN?So if took the same ACL and applied it as outbound, would the source need to be change to an IP inside the LAN?I am a bit confused by the data flow I'm seeing in packet tracer simulation mode to. I set up an ACL for testing purposes "access-list 199 permit ip 193.20.30.0 0.0.0.63 any" set as inbound, the idea being it permits any traffic from the .0 subnet.When I watch the packet in the simulation, it makes it to the destination address then is dropped by the router on it's way back out to the sender.
I'm trying to set up 2 separate networks in my home, both of which have access to the internet through a single ISP.I have set up my networks using 2 routers as described in the "Version 2" scenario found here: url...The problem is, a computer connected to the LAN side of Router 2 is able to ping and map shared folders on computers connected to the LAN side of Router 1. According to the writeup (last paragraph), this should not be the case.I have been over the setup multiple times to ensure it is per the writeup but each time, I am able to ping and map.Is there some additional router/computer settings that I may be missing?FWIW, here's my take on what is happening (with the ping): When a computer on the LAN side of Router 2 (submet 192.168.1.x) does a ping to a computer on the LAN side of Router 1 (subnet 192.168.0.x), Router 2 sends the request to its Default Gateway (since it's a different subnet).Router 1 however, recognizes this as its LAN side subnet and forwards the request to that computer. The ping response is then routed back from Router 1 to Router 2.
My office pc internet ADSL router is connected on USB port and office intranet router is connected to LAN post throuh a CAT-5 cable.Both have different gateways.I have manually configured both USB and LAN but internet and intranet does nt work together.I am required to disable one connection to connect the othet one.I want to remotely connect to my office pc and work on intranet( oracle database) .i connect through team viewer but as internet is on,intranet does nt open.i tried to add intranet gateway throuh command line also but it did nt work.office pc is xp ..home pc is vista..
ive been having some issues with my internet, i had an attack on my pc recently by some american orginization, ive reinstalled new windows on my pc, reset my modem, and nothign seems to work, i have too many tunnel adapters in cmd ip config i think, bell canada hooked up my internet lines and they actually joined two or more wires together and strung them up on the neighbours fence and mine and even wrapped it around a tree branch, god knows why they would even do that, maybe they think when the tree grows it will cost me money to fix it and theyll earn from thier mistakes instead of learn from them... anyway this is my ipconfig test results as explained in previous post from someone.Windows IP Configuration[CODE]
I have Windows 7 x64 and I'm using ICS to share my internet connection (cable-modem router from Comcast) with another 4 computers in my LAN.Today I decided to install a VPN free program called HOTSPOT SHIELD, and after installing it I can browse fine the Internet with this main computer, but the others in the LAN lost internet connection, although File-sharing still works fine and I can see the Networked computer in Windows Explorer or access them remotely with Remote Desktop Connection.I noticed that the Hotspot Shield program added several routes to my routing table, most of them in the IP-Range 10.31.X.X with a Mask of 255.255.248.0so this virtual Network-card that is created has a VARIABLE IP address 10.31.X.X, the first time I monitored it was 10.31.40.20.
Is this known bug that you cannot backup (export) full running or startup config from this switch? Will this be fixed in next firmware? (btw, still no new firmware with CDP support for this script altough sales literature mentions that it should have already been available...)Switch does let you backup configuration as text file (which looks similar to normal IOS config syntax), but it doesn't contain all settings so the file is pretty much useless to restoring the config to another switch.At least following settings are missing from the file:
- management interface config (including DNS settings) - passwords - remote syslog server config - SNTP server config - IGMP config - LLDP config
I am in the process of trying to replace a modem/router,the switch does not work with the new modem/router although if I connect the modem/router directly to my computer it works fine,so its not a router issue.I suspect that the settings need to be changed in the switch to allow the new router to work ?
How to get vlans working properly between sub-interfaces on a ASA and a trunk port on a switch.There seems to be issue with the VLAN's being assigned to the correct VLAN and this information being properly sent to the ASA over the trunk.
We seem to be unable to ping most of the interfaces except for one on the switch. Sometimes if we are lucky we are able to ping a host on a different vlan that is on the switch. This seems sparadic at best.
Logs on the ASA show traffic does not seem to be assigned properly to the correct sub interface. We have access rules on the ASA disallowing traffic not part of the same vlan. For example you will see networkA blocked on networkB when it really should be directed through networkA's sub interface.
Any example commands for the ASA and Switch for at least the basic requirements to enable all the VLAN's to communicate properly with the ASA?
I'm having troubles with this firmware in a SG300-28 switch. Actually the DHCP server, a new feature in this firmware release, doesn't work correctly. DHCP static reservations are not working: CLient ID and MAC address are not recognized correctly, and the DHCP server assigns the first free IP in the pool, rather than the reserved one.If Cisco engineers read this, plese correct the issue.
