Setting up Cisco SLM248GT-NA switch for VoIP

Hello Everyone,
We have a Cisco slm248gt-na smart switch in our office that I am trying to configure to support and optimize for VoIP. We have desktops hooked up off the phones in most cases. Are there any config guidelines to optimize the switch so it has proper QOS set and VoIP gets higher priority over data.
Thanks, Kind Regards

Hello Tom,
Thanks for your reply.
We have a pretty straight forward setup. We have 15 Cisco SPA303 phones hooked up to switch and the desktop are connoted via the phone. We have a wireless LAN and a corporate server that servers as a file sharing/vpn type setup. Other than that there are no devices hooked up. We had to implement auto voice vlan feature but were still running into issues like occasional poor voice quality and one way audio type issues. However I did notice something in the configuration menu "Telephone OUI", could you please help us on how to implement that. We are trying to implement best practice to avoid voip related issues that we have been having.
We also see all the ports in trunk mode. Is that the recommended setting or should we change it to access mode?
Thanks, Kind Regards

Cisco 3550 SMI switch for security setup ?

I have a 3550 SMI IOS 12.2 switch, I want to setup http, https, dns services for internet. I do not need to set up any mail or web server.
The connection as follows:
Internet ---------Modem----------3550-----------Computer
Modem has no security function, all the security setting will be on 3550 switch. So what is the best approach ?
Is it layer 2 or layer 3 security ? and can I run VPN for the internet surf ? Please kindly advise.
Thanks,
Susan

Thanks for the Reply.
When I config the switch I find out some interesting things, I am no sure if the
configuration is correct or I miss something ? Please help take a look.

Using Cisco MDS 9148 switch for switching and routing

Hi Gurus,
Can you please advice me! Can i configure interface trunking, routing and dhcp services on the Cisco MDS 9148 switch?
Thanks for your response!!

Tommy,
MDS9148 is a Storage SAN Fibre Channel switch, it doesn't support Ethernet, IP, VLANs, VLAN trunking, 802.1Q, IP routing, DHCP. It's meant for Fibre Channel connectivity between Fibre Channel server HBAs and Fibre Channel storage.

Best practice power setting when doing a Site Survey for VOIP

Hi Team,
Can someone please confirm or correct me. When doing a Wireless Active Site Survey for Cisco VOIP, I should be setting the Test AP to local power of 14, which is 25mW? Is this correct, or should it be another value? I asked the customer for the power of their weakest client and they do not know, but they claim there's a high probably that they will go with Cisco VOIP clients.
Thanks...

When you check the signal coverage, make sure the AP's radio transmit power does not use a transmit power greater than what the client devices can support. For example, by default, the Cisco Unified Wireless IP Phone 7925G uses the highest available transmit power by default (17 dBm / 50 mW for 2.4 GHz and 16 dBm / 40 mW for 5 GHz). It is possible to have a survey report that shows good coverage in all areas; however, if you have APs that operate at the highest transmit power, you might still experience uplink issues where the client devices do not support the same transmit power. For areas where there is deficient coverage, and you increase the AP transmit power to levels that the client devices cannot support, this only increases coverage on the downlink.

Switching for Cisco IPT

Here is a question a customer emailed me today
" so im looking at the Cisco IPT solution and its impressive. after noticing the costing, i see no way of justifying the switching infrastructure. our entire organization is based on dell switching and Cisco routers.
we intend to stay with this as our switches are new has QOS and POE enabled as well as IEE power compliant as i understand and will work with the Cisco Phone models. we can also acheive the same measure of redundancy as proposed in the 3-layer model that Cisco applies. please advise as to if there are any limitations of these switches as i cannot see any at this point in time"
from a pre-sales prospective how do you justify changing to Cisco, and more importantly, from a TECHNICAL prospective do we convince the customer to change or leave?

In terms of implementation and operation: if you follow the separate VLANs for voice and data model - which you probably should - you will have to manually set the correct VLAN on every phone in the phone settings. phones use CDP to discover voice VLAN. I've done a deployment with non-Cisco switches such as this, and it definately slows things down. Of course you don't want to hurt any feelings, but... there is a reason Dell was giving away their switches for free a few years back. I like to save money too, but I wouldn't stake my business on running critical infrastructure this level of switch.

Does cisco MDS 9000 switch by default set a little higher R_T_TOV?

Hi, All:
Not sure anyone has done LOS for cisco MDS 9000 switch before. I tried to insert code violation which is equal to 103ms but only see link reset but not NOS/OLS. is it because that Cisco MDS has default higher ? Or can we set R_T_TOV on switch?

Hi Larry - [this|http://lists.apple.com/archives/usb/2008/Oct/msg00021.html] was the only thing I could find about transactions timing out, but since you don't have anything plugged in, it really doesn't apply. Have you tried resetting your SMU?
If that doesn't work, run Disk Utility from your install disc and see what it comes up with. Your suspicion that the MB may be faulty is probably correct, and if you are still within the 90 day warrant period, you should call the repair place and have them replace it yet again.

Set up cisco SGE2010 combined with Dell 6248 switch

Hi, I have currently a Dell powerconnect 6248 switch combined with a netgear UTM router. I have a basic understanding on how things should work but I don't have the knowledge to apply it as I'm new to setting up vlan and the person before me did the basic configuration like this:
defined 5 VLAN in the netgear router
defined the same 5 VLAN in the dell 6248
connected the dell switch to the netgear router via a trunk port.
Right now all the inter vlan traffic pass thru the netgear router as the dell switch as a trunk port connected to the netgear box who then give dhcp and set himself as the default inter vlan route. I would like to stop that since I would like the cisco switch to handle all the vlan routing for both switch and those switch to send their dhcp request to my win2k8 server.
I did set the sge2010 in layer 3 mode from the small business telnet interface. I then setup the same 5 vlan in the cisco switch.
If I understand this well I need to define an IP address for each vlan interface on the cisco switch for it to be able to route things, I have set them all as x.x.x.3 (x.x1.3 vlan 1, x.x.2.3 vlan2, etc) Then I need both swtich to forward all dhcp request to my dhcp box wich is in vlan 2. My DHCP server will have 5 range of IP address to hand out. my server are connected directly to the dell switch on vlan 2. I have set up a port in the dell switch in trunk mode and did the same thing in the cisco switch and connected them togheter to send all vlan packet. The current setup doesn't work so I need some help to finalize that setup so that everything works.
If you need detail that I might have forgot to mention I wll gladly provide them.
Thanks !

For future reference, I finally succeeded in setting up everything the way I wanted it to be. I enabled layer 3 routing on the sge2010 switch, defined IP for each vlan interface, defined DHCP scope with vlan interface ip as the gateway. Added the ip-helper ip of the dhcp server on the sge2010, I defined 1 of the port on the cisco to trunk mode and added all vlan to it. I then defined all the same vlan on the Dell swith, added the ip helper address of the dhcp server for each vlan on the dell switch, defined a port on the dell swith in trunk mode and added all the vlan to it, connected both swith with an ethernet cable via the trunk port on each side and voilà all is working good. I finally had to define a static route in the cisco switch of 0.0.0.0 mask 0.0.0.0 with the ip of my internet firewall to gain internet access on both switch.

Cisco Nexus 1000v Virtual Switch for Hyper-V Availability

Hi,
Does anyone have any information on the availability of the Cisco Nexus 1000v virtual switch for Hyper-V. Is it available to download from Cisco yet? If not when will it be released? Are there any Beta programs etc?
I can download the 1000v for VmWare but cannot find any downloads for the Hyper-V version.
Microsoft Partner

Any updates on the Cisco Nexus 1000v virtual switch for Hyper-V? Just checked on the Cisco site, however still only the download for VMware and no trace of any beta version. Also posted the same question at:
http://blogs.technet.com/b/schadinio/archive/2012/06/09/windows-server-2012-hyper-v-extensible-switch-cisco-nexus-1000v.aspx
"Hyper-V support isn't out yet. We are looking at a beta for Hyper-V starting at the end of February or the begining of March. "

I have a problem for cisco catos 4232 switch.

i have entered the enable mode in cisco catos 4232 switch,but always there have been a remarks appearing all the time as follows:
2006 Feb 23 14:23:34 %SYS-4-P2_WARN: 1/Host 02:01:00:00:00:00 is flapping betwee
n port 3/34 and port 3/33
why?
thank you!
Best Respects!

Hi Friend,
The message indicates that your Catalyst 4500/4000 switch has learned a MAC address that already exists in the content-addressable memory (CAM) table, on a port other than the original one. This behavior repeatedly occurs over short periods of time, which means that there is address flapping between ports.
If the message appears for multiple MAC addresses, the behavior is not normal
If the error message appears for one or two MAC addresses, locate these MAC addresses in order to determine the cause. Issue the show cam mac_addr command in order to identify from where these MAC addresses have been learned. In this command, mac_addr is the MAC address that the error reports as flapping.
After you determine between which ports this MAC address is flapping, track down the MAC address. Connect to the intermediate devices between your Catalyst 4500/4000 and the device that has the problem MAC address. Do this until you are able to identify the source and how this device connects to the network.
Note: Because the MAC address is flapping between two ports, track down both of the paths.
These are other issues that can cause this message to appear
1) Server NIC redundancy problem
2) HSRP
3) EtherChannel misconfiguration
4) Host reflects packets back onto the network

Cisco PoE switch for WAP321

Could someone please point me to a Cisco small business switch that would be capable of powering five WAP321's?
I don't know the power profile on these APs but have noticed that the PoE injectors pump out 16.8 MAX watts. I can't find anywhere what the power profile is on WAP321 APs but ~17 WATTS seems to me to be quite high.
In fact, I was interested in the SF100D-16P which has a power budget of 64W over 8 ports... the price range is in my budget.
Could anybody tell my if the SF100D-16P can power 5-6 WAP321's sufficiently? Thank you.

The WAP support 802.3 AF. Although I don't know specific detail for the power profile I can assure it should not exceed 15.4 WATT. Typically the small business power draw is less than 8 watt per port. Devices which support CDP will also have a min/max draw that optimizes the POE functions.
However, the datasheet and admin guide does not make mention of any CDP

Snow and setting priority for voip voice packets?

I have an engine Voice Box 2 connected to my dual ethernet base station, for voip phone calls using a 1500kbps broadband connection. It all works fine, except sometimes the voice quality of phone calls isn't good - drop-outs occur. Engin support tells me there is a way to configure an airport BS to give priority to voice packet data over other internet data data, and this will improve the voice quality.
Is this possible with a snow BS, and if so how do I do it?

OK, Duane and anyone else. My question has been answered via telephone from Apple Australia, on Thursday 22 Feb 2007 at local time 9.01 pm. The answer is: There is no way that any version of an Airport BS can be set to prioritize voip voice packets over other internet packets of data.
Apple Supporters in other countries may disagree (not a surprise). I've been a Mac user since the first 1984 64K Mac, and I've not been too impressed with Apple phone service during the last 20+ years, so if another Apple tech elsewhere comes up with a different answer I would not be at all surprised.
So, first premise is my voip provider gave me incorrect info. Second one is maybe someone else gave them the incorrect info. One guess and no prizes as to whom this may have been.
Bigger surprise is that Apple seems oblivious to how popular voip phone is going to be in the immediate future, and that Mac users are likely to receive inferior quality voice quality and have no way to improve this by tweaking their Airports.

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!
