2960 dual purpose uplink ports

Hello folks, I just need to confirm the uplink ports for the 2960.
The Data sheet shows.....
WS-C2960-24TC-L
â¢ 24 Ethernet 10/100 ports and 2 dual-purpose uplinks (each dual-purpose uplink port has one 10/100/1000 Ethernet port and 1 SFP-based Gigabit Ethernet port, 1 port active)
â¢ 1 RU fixed-configuration
â¢ LAN Base Image installed
Does this mean that I can only have 1 active uplink port (interface) at a time?
Or
Does it mean that I can use either Copper or Fiber at a time?
Thanks in advance I appreciate your help.
Regards,
JP

Or one port as copper and one port as SFP.
Basically, the a copper and SFP port are paired, either of the pair can be used, but not both of the same pair at the same time.
As you have two uplinks, you have two pairs.

Catalyst 2960 uplink ports

Hi,
is there any difference between uplink ports (using 1Gbps SFP) and any another 10/100/1000 port on Catalyst 2960X ? What I mean is: if uplink port has a 1Gbps SFP and considering that standard port are 10/100/1000, is there a reason, for example related to Catalyst internal hardware and bus architecture, that should make me connect a server to the uplink port instead to any another port ?
Thank you a lot,
enrico.

Although you can purchase Copper SFP's, people generally use the SFP ports on a switch to connect fibre cables to which means they they get the full 12/24/48 ports for their hosts.
Using one or more of the standard ports for uplinks means there are less for hosts but if you have spare and don't want the cost of running fibre and purchasing additional SFP's then use the normal ports.

Best QOS Practice for a congested Uplink Port?

I have an MPLS uplink port to a carrier that carries both voice and data.
For example, Customer 3750 Switch 100MB Uplink--->100MB Uplink Carrier Router---Carrier Router 6MB MLPP Voice/Data MPLS Uplink with QOS configured for Voice subnet on carrier side too.
The port occasionally suffers from overutilizition and spikes to the full 6MB
I have a centralized CUCM that has phones that occasionally reset due to TCP 2000 timeouts (usually during the period of high utilization)
So that I can avoid most phone resets during high utilization I have prioritized all voice traffic (signalling and RTP streams) to EF
My question: What is best practice configuration for a congested uplink port? I'm going to assume the answer is it depends (the all great technical answer )
Here are my thoughts on how to configure the 3750 uplink port so far:
apply mls qos trust dscp
apply priority-queue out
(Here's where I'm looking for help)
apply some sort of policing or bandwidth statement on the interface to protect the voice traffic: What are the recommendations and what would those configurations look like?
I would apply these these configurations to the uplink ports at the edge site as well as the central site.
Any thoughts as to the best way to accomplish this?

You want to prioritize VoIP traffic at congestion points, which for you, looks to be whenever your LAN bandwidth hits your 6 Mbps WAN.
If the carrier takes your 100 Mbps, and doesn't just generally police all traffic to 6 Mbps, but instead has different priority queues for the 6 Mbps, all you should need to do, is insure you traffic is correctly processed by your WAN vendor. This, though, might require marking your traffic for the WAN provider.
If you carrier first polices all your traffic at 6 Mbps (many do), then you need to shape the traffic (with you own prioritization) before the provider "sees" it. If you need to "shape" on the 3750, there's a command to limit a port's bandwidth utilization, as a percentage. However it's not exact, so you may need to "shape" slower than 6 Mbps to insure 6 Mbps won't be exceeded. (BTW, for 6 Mbps, if you need to do QoS, you would be better off with an ISR.)
You also mention 6 MLPPP, but it's unlclear what your device is for that.
How to configure 3750 QoS is involved. Basically when you enable QoS, each port has four dedicated egress queues. By default, different traffic markings go into one of the four queues, each queue has same share of the bandwidth, and almost same share of the buffers. The PQ command you noted, enables the first queue to always transmit its packets first. Normally, you'll want to do that for VoIP bearer packets, which you've (insured are) directed to that queue. You also want to insure that VoIP signally packets are not likley to be dropped and, more or less, are forwarded quickly.
Cisco has multiple papers on QoS configurations, including papers for 3750s, so instead of my trying to present that, the above is intended as an overview. Feel free to post additional questions, the more specific, the more likely you'll get an answer.

Uplink ports and actual switches sfp usages (please help~~)

Dear all,
I am reading around to see the differences between uplink ports and normal ethernet ports. It seems to be uplink port just reverse the rx,tx pins and remove the needs of using a crossover cable.
I have done a simple representation of using the below (normal ethernet ports)

I assumed that the SWITCH ethernet port pins are naturally arranged as opposite from the PC so that a straight cable can be used and the same applies to a router port.
Q1) Hence from PC to Router ethernet port, I will need a cross cable, am I right ?
============================================================
Then I chance upon this website http://duxcw.com/faq/network/uplink.htm which states "A PC can be connected to an uplink port with a crossover cable"
As per my assumption above, a router has normal ethernet ports and uplink ports (for connecting to the wan/modem), since the normal ethernet ports of a router are in the order of (RX,RX,TX,TX) as shown above, I assumed the uplink port is (TX,TX,RX,RX).

An uplink port doesn't necessarily run at wire speed but it is more likely to.
But this doesn't mean you don't get oversubscription from the switch to other switches.
It's quite a big subject to cover but i'll try and keep it brief.
Internally within a switch there is a crossbar switch fabric which I think we covered before. Think of it of as pathways between ports. On any switch there are a number of ports that are capable of certain speeds.
Put simply if you take the number of ports on the switch and multiply that by the fastest speed the ports can operate at, if that number is greater than the switch fabric then the switch is said to be oversubscribed.
It doesn't mean in practice it will be oversubscribed but the potential is there.
What can happen though with oversubscribed switches is that the uplinks ports are guaranteed not to be oversubscribed ie. they do not need to contend with the other ports on the switch. It's complicated but it is to do with the connectors per port group etc. to the switch fabric.
But even though the uplinks ports can run at wire speed so they are not oversubscribed, if they are uplinks to other switches there may very well be more traffic combined from the other ports on the switch to that uplink port so you still get an oversubscription ratio.
But what would make it a whole lot worse was if your uplink port was oversubscribed within the switch as well.
So there is oversubscription within the switch and this is where we talk about ports running at wire speed or not and then there is oversubscription between different layers of the network eg. access to distribution for example.

Hi Noob,
On some kit like netgear hubs etc, you may find a little button or
slider switch which may be labelled MDI or MDI(X) this allows a
straight cable to be used between 2 Hubs or switches (Both DCEs).
Some Cisco switches/routers will allow you to do the same but in software
interface fastethernet 1/0/1
mdix auto
====================================
DTE devices like say your laptop PC NIC card has an MDI (Medium Dependant Interface).
Physically this wires out as ( For 10/100M):-
RJ45 PIN
1 -- TRANSMIT +ve
2 -- TRANSMIT -ve
3 -- RECEIVE +ve
6 -- RECEIVE -ve
DCE devices like hubs & swiches have MDI-X (Medium Dependant Interface - Crossedover).
Physically this wires out as ( For 10/100M):-
RJ45 PIN
1 -- RECEIVE +ve
2 -- RECEIVE -ve
3 -- TRANSMIT +ve
6 -- TRANSMIT -ve
So lets connect the device together with a STRAIGHT cable ( Function DTE to DCE)
PC/NIC = DTE = MDI                                SWITCH = DCE = MDI(X)
RJ45 PIN                                           RJ45 PIN
1 -- TRANSMIT +ve -------------------------------- 1 -- RECEIVE +ve
2 -- TRANSMIT -ve -------------------------------- 2 -- RECEIVE -ve
3 -- RECEIVE +ve --------------------------------- 3 -- TRANSMIT +ve
6 -- RECEIVE -ve --------------------------------- 6 -- TRANSMIT -ve
So we transmit from the DTE and receive on the DCE and vice versa (BINGO).
Remember Routers are regarded as DTEs
=================================
So lets connect 2 switches together with a CROSSOVER cable ( Function DCE to DCE)
UPLINK to UPLINK
SWITCH = DCE = MDI(X)                           SWITCH = DCE = MDI(X)
RJ45 PIN                                           RJ45 PIN
1 -- RECEIVE +ve -------------------------------- 3 -- TRANSMIT +ve
2 -- RECEIVE -ve --------------------------------- 6 -- TRANSMIT -ve
3 -- TRANSMIT +ve ------------------------------ 1 -- RECEIVE +ve
6 -- TRANSMIT -ve ------------------------------- 2 -- RECEIVE -ve
So we transmit from the DCE and receive on the DCE and vice versa (BINGO).

Configuring RSTP on Uplink Ports

I have Two Catalyst 2950 Switches, I connected both Switches through their Two Uplink Ports. Now I Want to run RSTP b/w these ports by doing this:
Config t>int gi 0/1> spanning-tree mode rapid-pvst
But this command not works and shown as "Unrecognised command?"
So how I can run RSTP on switch specific ports?
Regards to everyone...Shahid

Thanks for helping me
As you told that RSTP is a global function and it cant run on specific port, so it means when I run spanning-tree mode rapid-pvst command then it enables RSTP on all 24 ports but will it also enable RSTP on Gigabit/uplink ports?
Lastly I want to discuss my Network topology on which I will run RSTPI have Six 2955T-12 Industrial Grade Switches. Two of them are Core Switches (using Two switches to provide redundancy in case of one Switch failure) and Four Switches are Access Switches for LAN1 and LAN2 (Again for LAN1 we using two switches for redundancy and same for LAN2). We will connect all Switches to each other with their Uplink Gigabit ports.
But remember we will test this topology in Tree as well as in Ring topology to find the lowest RSTP re-convergence time. One more important thing is that both LANs Computers (i.e. LAN1 and LAN2) have Dual LAN cards so that they will be connected with their both access Two Switches with Two LAN cards (we using Two LAN cards in Computers b/c of redundancy)
Now can you tell configuration of RSTP (also we should run on whole switch or on specific ports) and on which switch I should run RSTP in case of Tree topology and if possible in case of Ring topology (actually we want to test to find which topology will give the lowest RSTP reconvergence time)? Also I want to know that how we can run/enable RSTP on only Uplink Gigabit ports?
Also can I create Two or three VLANs in Catalyst 2955T-12 Switches but all VLANs should be Up?

Shahid

Please help with a new dual purpose PC build

Hi everybody in AdobeLand!
I've been reading various boards and hardware sites and have started piecing together a dual purpose computer system. It will be used for both video editing (of pre-shot hacked, high bitrate I-Frame Panasonic GH2 DSLR and camcorder footage using the AVCHD codec @ 1080p 24 and 30 fps) and webcasting/streaming purposes. I would build two computers for each task, but it's just not in the budget right now. I'm already stretching things as is.
I'm still not sure if I will be using Adobe Premiere or Sony Vegas Pro 12 yet, though it seems like they organize their folders and file structures about the same. Adobe's cloud service has me a bit scared off right now. This new scheme feels like they have their hand purpetually in your wallet, which does not sit well with me. I may still go with Vegas 12 just to avoid that hassle right now. Help guide me here, experts! Telestream's Wirecast is being used for multi-cam switching and graphics for live and pre-recorded material being compressed and streamed.
Back on topic:
Here's the build as of right now...
OS: Windows 7 64-Bit Professional (Windows 8 absolutely sucks!)
CPU: Intel i7-4930k 6-Core Ivy Bridge (own)
Motherboard: Asus P9X79 Pro (own)
Memory: Crucial Ballistix 1.35v Sport DDR3L @ 32 GB (own)
GPU: EVGA GTX 770 FTW w/ 4 GB (will buy another HD monitor at a later date, hence the 4GB memory)
Case: Fractal Design XL R2 Full Tower
CPU Cooling: Noctua NH-D14 w/ SE2011 Bracket
PSU: Corsair RM1000 Quiet Series / 80 Plus Gold / 1000 Watts
Monitor: Dell U2412M Ultrasharp 24 inch / 1920x1200
Optical Drive: LG Blu-ray Writer
Keyboard: Microsoft 4000 Ergonomic
HDMI capture cards: Blackmagic Designs Decklink Mini (x2)
Storage:
I bought two Samsung 840 Pro SSD drives: one 128 GB and one 256 GB
Thinking about possibly 2 (maybe 3-4 if I really stretch) Seagate ST3000DM001 3TB HDD's.
I could sure use your help with any advise on arranging the storage to get the best bang vs. buck in speed and storage utilization (Wirecast can be setup to record live webcast sessions at 720p or 1080p in compressed files... probably no more than 120 minute webcasts... so that comes into play as well). Just don't have the funds for an uber-expensive RAID controller card right now.
Any opinions overall on the parts for the current build? I still have time to send back and exchange anything already purchased.
Thank you for your time and consideration.

What do you not understand from:
With all the reading and writing going on, on the boot disk, it is understandable you need a (number of) dedicated disk(s) for video editing, especially with the bandwidths required when the clip duration is short and the number of tracks exceeds one and uses a codec more complex than DV. The kind of files used during editing are, in order of their need for speed:
Media cache & Media cache database files, created on importing media into a project. They contain indexed, conformed audio and peak files for waveform display.
Typically small files, but lots of them, so in the end they still occupy lots of disk space.
Preview (rendered) files, created when the time-line is rendered for preview purposes, the red bar turned to green. Read all the time when previewing the time-line.
Project files, including project auto-save files, that are constantly being read and saved as auto-save files and written when saving your edits.
Media files, the original video material ingested from tape or card based cameras. Typically long files, only used for reading, since PR is a non-destructive editor.
Export files, created when the time-line is exported to its final delivery format. These files are typically only written once and often vary in size from several hundred KB to tens of GB.
When you are doubting which category of files to put on which kind of disk, especially when using both SSD's and HDD's, keep in mind that the speed advantage of SSD's over HDD's is most noteworthy with the Media cache & Media cache database. These files are frequently accessed, are small and there are many, so reducing latency and seek times and increasing transfer rates pays off by putting these on a SSD, rather than on a HDD, even if it is a raid0. Export files can go to the slowest volume on your system, since you only export once. To help you decide, I have added priority rank-numbers for speed, with 1 for the fastest volume and 5 for the least speed-demanding category.
and
Well, in the benchmark tests we have not seen any noticeable difference between SSD and HDD in terms of performance, but logic dictates that there should be a small difference in performance when the volume used for media cache is a SSD, because of the much faster access time and lower latency compared to a conventional disk. If it is noticeable, it is specifically on this volume with the media cache and media cache database, due to the large amount of small files that need to be accessed and written. This argument does not apply to the media volume with a limited number of files, that are very big in size.

Why the Fibre uplink ports are down state even after giving no shutdown command at the interface

Hi
My Predecessors brought 2 CISCO 3750 switches and implemented LACP on these core switches. Due to looping in the network the Fibre uplink ports GigabitEthernet1/1/3 and GigabitEthernet2/1/3 are down (I think these uplink ports are mirrored in the LACP concept)
Please see below from the configuration.
I logged into the core switch and went to this particular interface GigabitEthernet1/1/3 and I gave the following command and still the port is in the down state after I gave no shutdown command. Do I need to give the same no shutdown command at interface GigabitEthernet2/1/3 as well ?
Switch-Core1(config) interface GigabitEthernet1/1/3
Switch-Core1(config-if)#no shutdown
Switch-Core1(config-if)#

It is possible you are overloading that little 4215. If that is the case you should also be seeing "missed packet percentage" messages in your events.
How much traffic is your 4215 getting? Those sensors will start to drop packets for inspection at about 30 Mb/s.

WRT54G v5 Uplink Port Not Designated

Running out of ethernet ports, wanting to add a Fast Switch (SMCGS5), the back panel of this router doesn't designate which port is an uplink port, likewise the switch. Unless I went blind, my User Guide and the User Guide online for this model, has no mention of any uplink port designation, other than the 3rd paragraph of the online Product Description, for this model.
I'm currently using one laptop, two PC's, and one NAS, and want to add one more wired PC. I'm noticing intermittent stalling or freezing after I installed the switch into Port 1. So I switched over to running to the switch from Port 4, noticed no difference in wired performance. Shutdown everything to be used on the network, including doing a reset all, no change in wired performance when the switch is used, otherwise, works fine with existing router/switch ports.
Took switch to friends house to install in their network. They have no problems with this switch.
Would anyone be able to help me identify if the WRT54G v5 Router even has a uplink port? Or are "all" the ports, uplink ports? I've read the pre-posting information and have searched for similar question(s).

You can still keep your linksys router...I would recommend you to upgrade the firmware on the router , then reset and re-configure it...
Download the firmware from here ,
Follow these steps to upgrade the firmware on the device: -
Open an Internet Explorer browser page.In the address bar type - 192.168.1.1
Leave username blank & in password use admin in lower case...
Click on the 'Administration' tab- Then click on the 'Firmware Upgrade' sub tab- Here click on 'Browse' and browse the .bin firmware file and click on "Upgrade"...
Wait for few seconds until it shows that "Upgrade is successful" After the firmware upgrade, click on "Reboot" and you will be returned back to the same page OR it will say "Page cannot be displayed".
Press and hold the reset button for 30 seconds...
Then, unplug the power cable while holding down the reset button for another 30 Seconds...
Plug the power cable back in, and keep holding down the reset button for another 30 Seconds...
Release the reset button...Now re-configure your router and connect it to your switch...I hope this works...

SR-IOV Uplink Port with NIC Teaming

Hello,
I'm trying to setup my uplink port profile and logical switch with NIC Teaming and SR-IOV support. In Hyper-V this was easy, just had to create the NIC Team (which I configured as Dynamic & LACP) then check the box on the virtual switch.
I'm VMM it does not seem to like to enable NIC Teams with SR-IOV:
Can anyone advise? I'm not using any virtual ports. I just want all my VMs to connect to the physical switch though the LACP NIC Team, something which I thought would be simple.
I have a plan B - don't use Microsoft's NIC Teaming and instead use the Intel technology to present all the adapters as one to the host. I'd rather no do this.
Thanks
MrGoodBytes

Hi Sir,
"SR-IOV does have certain limitations. If you configure port access control lists (ACLs), extensions or policies in the virtual switch, SR-IOV is disabled because its traffic totally bypasses the switch.
You can’t team two SR-IOV network cards in the host. You can, however, take two physical SR-IOV NICs in the host, create separate virtual switches and team two virtual network cards within a VM. "
There is really a limitation when using NIC teaming :

Dashboard for only Monitoring uplink ports ~~~~~SCOM 2012 R2

Hi Guys,
I want to monitoring signal interface of switch like uplink port. And same i want create dashboard.
Please help me out for creating dashboard for only signal uplink interface port.

If you want to monitor the interface status on a switch, you'll have to build a custom monitor. (Unless you use supported devices e.g. Cisco Catalyst).
Go to authoring > monitors. Under the class 'Node' you can make a new monitor. Choose for SNMP and follow the wizard.
You'll need the OID to monitor. Usually you can find this OID in the MIB's (using a MIB browser) of your device.
MIB's can be found on the vendor website.

SCVMM2012r2 UR3 : Even with no Virtual switch assigned, an uplink port profile remains

Hi,
What I'm tryng to do, is to unassign an uplink set on my host, set to the wrong NIC (actually, on 3 NIC, event if I specified 2 when I added the logical switch...).
To proceed, I deleted the Logical Switch assigned in the host properties on Virtual Switches tab.
On my host, the teaming has been deleted, but unfortunately, on one of my NIC, the subnet set in my Logical Network subsit in "Logical Network Connectivity" and is greyed out.
It's said "The subnet an VLAN information is set by an uplink port profile set 'tVMNet' associated to this host an cannot be changed here".
But, if I removed the virtual switch, how can it be?
Thanks for any advice, I'm stuck

Hi all,
I did finaly remove the cluster from SCVMM and added it back, and it's working now. No more ghost config remaining.
I'm working on SCVMM from 3 days now, and I'm really not sure that's the easy to use tool we need to manage our small private cloud... It's buggy, slow, oposite of ergonomic and far too much cloud provider oriented...

NCS wired MAC trace incorrectly puts MAC at uplink ports

Greetings,
I generally love the Cisco Prime NCS functionality which allows one to quickly trace a MAC address to a switch and port. However, I'm having trouble with some MACs appearing at the uplink port of a closet switch rather than it's real access port on a different. While it is true that this PC's MAC is in the CAM for that closet uplink port, it's there with hundreds of others. It is also in the CAM for the port it is actually connected to, and in that case it's the ONLY MAC for that port, as expected. Both switches are functioning within NCS, and in fact if I drill down into the switch it is connected to, the client detail shows this MAC connected to the proper port. It's just the search trace that "incorrectly" shows it out at some uplink. In fact, it moves around to different closet uplinks (per the MAC search history results). It doesn't only happen with this MAC, either. I kind of sold the customer on this functionality and it's a little embarrassing.
1. Has anyone seen it and knows of a way to get it to show correctly and/or prevent this problem?
2. What criteria does NCS use to determine where to place the item when the MAC appears in multiple places? I would think it would at least pick a port that does not have other MAC addresses on it first, under the assumption that ports with multiple MACs are uplinks (I realize that there are cases where it COULD be on a multiple MAC port, such as an uplink to an unmonitored switch...not the case here). I can tell you that in the cases I've noticed, the uplinks are not 802.1q, just access ports.
Thanks!

Had the same issue here. Here is the best solution I have found so far:
Hotspot + Pepwave Max On-The-Go (w/ Load Balancing) + Airport Extreme
I have a VZW MiFi, but I believe this set-up will work with other hotspot devices. I actually have 2 MiFi Hotspots with a monthly allowance of 20G each. They are plugged directly into the Pepwave router (aka, tethered). (Note: you have to have the right cable to do this. The one that came with my Hotspot was only for charging.) If, for some reason, you cannot tether with your Hotspot device, you want a router that offers WiFi as WAN. The Pepwave will do this. The Pepwave is connected to my Airport Extreme via ethernet cable. I have the WiFi on the MiFis and the Pepwave turned off. So the only visible network is my Airport Extreme. The Pepwave is essentially just functioning as a modem.
I used to have a Cradlepoint, but I did not find it very user friendly--too complex for home use. The Pepwave Max OTG is awesome. I got the one with Load Balancing so it allows you to connect up to 4 cellular devices. If you only need the one Hotspot, you can just get the cheaper Pepwave Max OTG. The Pepwave allows me to run off one of the MiFis until I hit my 20G/month allowance, then it automatically switches to the other one. That way I never max-out on my monthly data allowance. Additionally, it gives you a real-time, hourly, daily and monthly running tally on data usage.
The guys at the 3Gstore are excellent and can help you figure out the best solution for your situation.

Dell Optiplex 780 standard size tower PC dual monitor display port graphic cards

Yes, only my boss informed me that they have to be display ports, he didn't tell me why.
I'm unable to buy from ebay or craiglist either & my local vendor doesn't have any in stock.

Quite a mouthful I know! but I need these specific graphic cards, ideally with next day delivery:
Dell Optiplex 780 standard size tower PC (Non SFF) dual monitor display port graphic cards
Any recommendations? I can find 2 on amazon (UK) I need 3!

3560E Switches and 10G uplink ports

Hi!
Thinking of 3560E switches with 2 X2 10G uplinks, I was wondering if I can use, at the same time, 1 uplink port @ 10G and the other one @ 1G, with the proper CVR-X2-SFP converter and SFP modules.
Thanks in advance!
Regards,
Martin.

Believe if you use a TwinGig converter in one of the module slots, you can connect one or two gig SFP links to it while the other module slot is 10 gig.
