Uplink ports on 6506E and UCS FI 6248's

Hello, I am trying to get my UCS on line with two uplink ports in an ether channel connected to a single 6506E switch with dup sup's. I have FI-A in PO100 and FI-B in PO200 on the 6500 and FI's.
The problem I am having is that only one member of each port-channel will come up, I have swapped the TWIN-AX cables with not luck. I have opened a TAC they suggested replacing the 10GB line card in the 6500. which I did this morning and still only one member of each channel will come up. These are the port setting from 6506E side, if anybody can see a reason why they might not be configured correctly please let me know.

Hello John,
Please SSH into UCS FI and provide output of following commands
connect nxos a
show port-channel summary
show lacp system-identifier
show lacp counters
show tech-support lacp all | no-more
You can also share above information with TAC engineer . If could collect similar info from Cat 6K , that would also be helpful.
You can turn debugs on FI and bounce the port-channel and stop the debugs to further investigate the issue.
connect nxos a
debug lacp all

Port-Channel issue between UCS FI and MDS 9222i switch

Hi
I have a problem between UCS FI and MDS switch port-channel. When MDS-A is powered down the port-channel fails but UCS blade vHBA does not detect the failure of the port-chanel on UCS-FI and leaves the vHBA online. However, if there is no port-channel between FI-->MDS it works fine.

FC port channels between MDS and UCS FI best practice?

Hi,
We would like to create FC port channels between our UCS FI's and MDS9250 switches.
At the moment we have 2 separate 8Gbps links to the FI's.
Are there any disadvantages or reasons to NOT do this?
Is it a best practice?
Thanks.

As Walter said, having port-channels is best practice. Here is a little more information on why.
Let's take your example of two 8Gbps links, not in a port-channel ( and no static pinning ) for Fibre Channel connectivity:
Hosts on the UCS get automatically assigned ( pinned ) to the individual uplinks in a round-robin fashion.
(1)If you have some hosts that are transferring a lot of data, to and from storage, these hosts can end up pinned to the same uplink and could hurt their performance.
In a port-channel, the hosts are pinned to the port-channel and not individual links.
(2)Since hosts are assigned to an individual link, if that link goes down, the hosts now have to log back into the fabric over the existing working link. Now you would have all hosts sharing a single link. The hosts will not get re-pinned to a link until they leave and rejoin the fabric. To get them load balanced again would require taking them out of the fabric and adding them back, again via log out, power off, reload, etc...
If the links are in a port-channel, the loss of one link will reduce the bandwidth of course, but when the link is restored, no hosts have to be logged out to regain the bandwidth.
Best regards,
Jim

UCS FI 6248 to Nexus 5548 San port-channel - not working

Hi all,
I'm sure I am missing something fairly obvious and stupid but I need several sets of eyes and help.
Here is the scenario:

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.

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)

RX

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).

Q2) So how can the PC connect to the Router's Uplink port using a crossover cable ? Shouldn't it be using straight cable instead if it is trying to connect to a router's uplink port ?

Q5) If i connect a switch Uplink port to another switch Uplink port, does it means that I have to use a crossover cable ? does SFP fiber come with "crossover" type too ?
============================================================
Q6) If an uplink port in a switch is use to connect to a router (can we?), do i need to use a crossover cable then ? since a normal switch ethernet port will use a straight cable to connect to a router port ? as shown below

Q7) Last but not least, if a design connect two switches using SFP uplink ports on both side, what would be the main purpose ? to increase the amount of ports ? Why not stack them then ?
Sorry for the lengthy post, will really appreciate if some gurus can shed some light on the above.
Thanks a million.

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).

Vsan membership down on mapped FC uplink port

Hi,
since I updated Cisco UCS Manager, all Chassis and Fabric Interconnects to version 2.2(1), I get some minor faults.
I configure ports 31 and 32 as FC uplink ports and mapped each port to a vsan:
Port 31 = VSAN "blue"
Port 32 = VSAN "red"
(I know, this is not common to map two diffrent VSANs to the same fabric, but I have to )
Since the update, I get minor faults:
Port 31 --> FCoE or FC uplink is down on VSAN "red" / membership-down
Port 32 --> FCoE or FC uplink is down on VSAN "blue" / membership-down
I have no FC port channels or FC trunking mode activated. Fabric Interconnect is in EHM.
Same in the other fabric.
Can someone help me or is this the same cosmetic issue as discussed in the quote?
FCoE Uplink vsan membership fault for any vsan not configured upstream Symptom:Fabric Vsan Membership Down fault message on FCoE uplink portsSeverity: MajorCode: F1083Name: Fabric Vsan Membership DownConditions:Observed with UCSM 2.1 and when FCoE uplink port is configured on the Fabric InterconnectWorkaround:None.Error message is cosmetic.
Thanks in advance

Hi HugoStiglitz
I saw this message , after upgradet to 2.2(1d)
but In several times , Cleared this message .
Fist of all ,
I Removed All FCoE Uplink Cable whose FabricInterconnect-A
and then
I saw FCoE or FC uplink is down on VSAN Red and blue
but, FabricInterconnect-A has no VSAN blue in this port-Channel
In several times ,
FCoE or FC uplink is down on VSAN blue is clear.
I have no idea , when clear this messages .

Uplink port VLAN

Hi there:
I'm lost
I know when you have for example two uplink ports that belong at the same vlan, and two or more vNICs asociated at this vlans, pinning happen dinamically
I know how configure a VLAN and assign it to an vNIC
But I can't found how to associate the uplink port to this VLAN in UCS manager
Can anybody help me please
Thank you in advance
Al

Al,
In the end-host mode for the ethernet, once you define the vlan in the UCSM the vlan is automatically assgined / configured on all the uplink and the server ports.
Here is a chapter from the config guide:

However starting with version 2.0 there is a feature under which you can control or confiure different vlans on different uplink ports. This feature is L2-disjoint feature and here is a URL to configure it:

Management vlan with the 1000V and UCS

If I want to use VLAN 10 for management, I would have to configure the following:
1000V -VM vEthernet port profile access port with VLAN 10, Ethernet uplink profile includes VLAN 10
UCS - vNIC in Service Profile, include VLAN 10, and include VLAN 10 in uplink trunk from UCS
Upstream switch: Include VLAN 10 in trunk port.
OK?
Now, this management VLAN, can I Iuse this for everything? I mean for 1000V management VLAN, vSPhere management, FI management and switch management? Or should for instance the 1000V management be different from the others?

Hi Atle,
Yes, what you have mentioned is the correct in terms of activities you need to carry out. However i would like to add a few:
1) define the vlan on the UCS - unless you do this you will not be able to add it to the vnic. Plus once you have the vlan defined it will automatiaclly get added to the trunk list on the uplinks ports (unless you l2-disjoint configured)
You can have the same vlan for all the management, unless you have certain traffic you would not like certain device to see / reach.

Stop ethernet uplink port will cause appliance port down

Dear All,
I would like to make sure what kind of network traffic will communicate internal in FI.
I disabled the uplink port, and found appliance port was also down.
Does appliance port need to route to uplink port and then back to UCS server ?
Thank you for clarification.
Best Regards,
Dennis Dai

Expected behavior. By default, if there are no uplinks online & fwd, then all southbound links (server links and appliance ports) will also go down.
See Abi's explanation here for details how to modify this behavior.
https://supportforums.cisco.com/thread/2187144?tstart=0
In short you have to change the Network Control policy of the Appliance port from the Equipment Tab.

Robert

Bundle the uplink ports on FI ?

Hi,
Can i "bundle" two uplink ports into an Etherchannel and then statically pin the server ports to the "bundle" (portchannel) and not the individual links ?
regards,
Geert

Geert,
Yes, you absolutely can uplink the FI with a port-channel to VSS or vPC.
See this for a visual of this design:
http://www.internetworkexpert.org/2009/07/05/cisco-ucs-vmware-vswitch-design-cisco-10ge-virtual-adapter/
I think Mike Frase was referring to how the IOM (I/O Module) inside the blade enclosure uplinks to the FI -- and he is correct that port channel is not currently an option for those links.
Cheers,
Brad

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)#
Please see below After no shutdown command given still these 2 Gigabit fibre uplink ports are down.

Please let me know if I am doing something wrong .Please post me some tutorial to sort this.

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...

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.
