Configure port channel between IO Module and FI

Hi,
I have the current setup
UCS chassis (4 uplinks) --> FI --> (Port channel) --> N5K --> (port channel) --> VSS 6500
I configure port channel between IO Module and the FI by changing to policy to "Port Channel" and set the link to 4
FI has created a portchannel under "Internal" containing all the FI interfaces that are connected to the IO module.
I have installed ESXI on a blade but i was unable to reach it, even the esx was unable to ping the gateway.
VLAN tagging is enabled from the ESX server.
I have issued the command "show mac address-table | inc <mac address of the vnic assigned from thre service profile> on both the N5K and thr 6500 and the mac is there.
I have allowed all the vlans on the vNIC from the service profile.
am I missing anything?
thanks

Hello,
Can you please check whether your ESXi vmkernel interface ip address learned on right VLAN on FI / upstream switch or not.
connect nxos
show mac-address-table | inc

Create port channel between UCS-FI and MDS 9124 (F Mode)

Dear Team,
We were trying to create port channel between UCS FI and MDS 9124
But the port channel not getting active in F mode on MDS 9124
FI is in FC End Host Mode
We have enabled FC uplink trunking on FI
We have enabled NPIV on MDS
We have enabled trunk on MDS
FI and MDS in default VSAN
To check we changed the FI mode to FC Switching mode and port channels became active but in E mode
when we enabled FC uplink trunking on FI and FC Switching mode port channels became active in TE mode
but in both the above cases showflogi database shows WWPN of SAN alone not showing any from FI.
How to achive this?
Have read that no need to change the swicthing mode to FC Switching mode and keep as FC Endhost mode
SO how to achieve Port channel with F mode in MDS and FI ( Mode showing as NProxy)
Does it has to do anything with MDS NX-OS version? (https://supportforums.cisco.com/thread/2179129)
If yes how to upgrade as license for ports came along with Device and we do not have any PAC/PAK or license file as it came
with license
Also we have seen 2 files availabe for download (m9100-s2ek9-kickstart-mz.5.2.8b.bin and m9100-s2ek9-mz.5.2.8b.bin) which to use
Thanks and Regards

Hi Jo Bo,
what version of software if your MDS running?
On your UCS do connect nxos and show inteface brieft and look at the mac address.
it is possible that you might be hitting the bug below. if this is the case you might need to upgrade the firmware on your MDS.
Add MAC OUI "002a6a", "8c604f", "00defb" for 5k/UCS-FI

SAN Port-Channel between Nexus 5000 and Brocade 5100

I have a Nexus 5000 running in NPV mode connected to a Brocade 5100 FC switch using two FC ports on a native FC module in the Nexus 5000. I would like to configure these two physical links as one logical link using a SAN Port-Channel/ISL-Trunk. An ISL trunking license is already installed on the Brocade 5100. The Nexus 5000 is running NX-OS 4.2(1), the Brocade 5100 Fabric OS 6.20. Does anybody know if this is a supported configuration? If so, how can this be configured on the Nexus 5000 and the Brocade 5100? Thank you in advance for any comments.
Best regards,
Florian

I tried that and I could see the status light on the ports come on but it still showed not connected.
I configured another switch (a 3560) with the same config and the same layout with the fiber and I got the connection up on it. I just cant seem to get it on the 4506, would it be something with the supervisor? Could it be wanting to use the 10gb port instead of the 1gb ports?

Issues with a port-channel between Nexus 5K and 4506

FC Port Channel between UCS and MDS.

Hi All,
I am new to Cisco Fabric Concepts. In my enviornment i have a F port channel(8 Port Group) created on MDS 9513 switch and this Fport
channel is connected to Cisco UCS 6296 FI. The Cisco UCS Blade servers are connected to the Fabric Interconnect .
On MDS NPIV is enabled.
Can anyone explain the below questions.
1. Why do we create an F port Channel Group and connect it to the UCS FI? Is this something similar to Brocade Edge to AG Switch Connectivity.
2. How to configure F port Channel Group in MDS . Can anyone explain with an example.
3. Do we need to make any Configuration on UCS FI ports for server connectivity and Channel port Connectivity if yes what are the steps required to
do the same.Does the WWPN shows up in the FLOGI Database if the connectivity and configuration looks good in UCS FI and MDS.
4. What happens when a VSAN on MDS switch is added to the Port Channel.
Thanks and Regards,
Santosh surya

1. Why do we create an F port Channel Group and connect it to the UCS FI? Is this something similar to Brocade Edge to AG Switch Connectivity.
F port channel is proprietary; therefore any such F port channel between UCS FI and Brocade doesn't work.
2. How to configure F port Channel Group in MDS . Can anyone explain with an example.

flogi database is on the MDS, not FI; there are however UCS CLI commands, like "show npv ...."
4. What happens when a VSAN on MDS switch is added to the Port Channel.
If its not created on UCS, it will just not become the status "up"

LACP port channel between 6509 and Nexus 7K

We are in the process of migrating from dual 6509's to dual 7010's. We have moved our 5k/2K's behind the 7K and have layer 2 up between the 6509 and 7K. This link is configured as a port channel with 2 1gig links using LACP. The port channel is up and working and traffic is passing but it doesn't appear the load it equally distributed between the links. Both the 7K and 6K are setup for src-dst-ip for the load balancing. The links have been in place for over 12 hours and I would have expected them to "equal" out. Has anyone had this issue in or is this to be expected? For clarification there is not VPC inolved in this configuration it is simply a port-channel between one 6509 and a 7010.
Thanks,
Joe

how many ports are you using in this port channel.
can you paste the configuration of the channel ports and the interface.
check the sh log if you are getting any log related to the port channeling.

SAN Port Channel between 6120 and Brocade

Has anyone setup or know how to setup a SAN Port Channel between 6120s and a Brocade FC switch? I know that it requires UCS firmware 1.4 but I don't know what the Brocade requirements are.

The SAN port channel is Cisco proprietory. You cannot setup SAN port channel with Brocade. Sorry

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

Port-channel between ACE4710 and switch

Hi all,
I have configured port-channels on ACE and switch. Full-duplex and speed 1000Mbps are set on both sides. The configurations of port-channel on both sides is same. But there are output drops on the switch. See:
Last clearing of "show interface" counters 00:31:24
Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 536
Why there are output drops on the switch? There is no half-duplex and both sides have the same speeds.
Thank you
Roman

Hi Roman,
Please paste the configuration of the ACE and Switch

What can be the max difference in cable lengths that we can have between the ISLs in a port-channel between MDS switches?

Hello All
What can be the max difference in cable lengths that we can have between the ISLs in a port-channel between MDS switches? Do we have any documentation?
Thanks
Chetan

competitive solution instead recommends a distance variance of 30 meters or less among ISLs within a trunk. If the distance variance is greater than 30 meters, undesired and degraded performance will occur. For example, if a trunk has a distance of 100 kilometers, the competitive trunking solution allows a cable length variance of only 0.03 percent!

Could I configure local switching between sub-interface and global interface on ASR9k?

Could I configure local switching between sub-interface and global interface on ASR9k?

For 2 interfaces it is probably best to use an xconnect. It is faster and saves system resources (eg mac learning doesnt apply to xconnect).
Config example:
l2vpn
xconnect group link
p2p link
interface Bundle-Ether100.4321
interface Bundle-Ether500.4321
EFP config:
interface Bundle-Ether100.4321 l2transport
encapsulation dot1q 4000
rewrite ingress tag pop 1 symmetric
interface Bundle-Ether500.4321 l2transport
encapsulation dot1q 2000
rewrite ingress tag pop 1 symmetric
This example shows that you can link 2 EFP's with different vlan's together if you'd pop the tags.
If the EFP's are of the same vlan, then popping the tag can be done but not a must. In general it is recommended to always pop vlan tags so there is a standard EFP design, but not for any technical reasons.
When you use a bridge domain and using a BVI, you MUST pop the tags as the BVI has no notion of a vlan tag and wants to see "plain ethernet".

Difference between ACE module and ACE appliance

Hi All,
Can someone help to understand the difference between ACE module and ACE appliance, as i am observing ACE module is providing more throughput when compared the ACE appliance, Is the only advantage we getting with contexts ....
thanks inadvance,
Narayana Mallidi

Hi Narayan,
Apart from providing throughput, ACE module has more to offer ,
http://docwiki.cisco.com/wiki/Cisco_Application_Control_Engine_%28ACE%29_Troubleshooting_Guide_--_ACE_Resource_Limits
The above link will provide a comparision of ACE module and Ace appliance interms of scalability. Apart from that legacy modules wont support compression, but ACE 30 module can support compression.
The major advantage of ACE 30 module is with resepct to SSL throughput, SSL TPS, L4 & L7 CPS, & Concurent Connections per second, apart from the increased contexts

Diff between Function Module and subroutine

sir,
explain the difference between Function Module and Subroutine.

Hi Sandeep,
Subroutines:
Subroutines are procedures that you can define in any ABAP program and also call from any program. Subroutines are normally called internally, that is, they contain sections of code or algorithms that are used frequently locally. If you want a function to be reusable throughout the system, use a function module.
Function Modules:
Function modules are procedures that are defined in function groups (special ABAP programs with type F) and can be called from any ABAP program. Function groups act as containers for function modules that logically belong together. You create function groups and function modules in the ABAP Workbench using the Function Builder.
Function modules allow you to encapsulate and reuse global functions in the R/3 System. They are stored in a central library.
Unlike subroutines, you do not define function modules in the source code of your program. Instead, you use the Function Builder.
Regards,
Sunil

How to configure a port channel with VLAN trunking (and make it work..)

We're trying to configure a port channel group with trunked ports to connect a NetApp HA pair. We want to create two data LIFs and connect them to the switch stack. We are trying to create 2 data lifs, one for cifs and one for nfs that are on different vlans.
We want the same ports to be able to allow multiple vlans to communicate. (trunked)
These data lifs should be able to fail over to different nodes in the HA pair and still be able to communicate on the network.
What this means is that we have to connect 4 ports each for each node in the NetApp HA Pair to the switches and create a port channel of some type that allows for trunked vlans. When we configure the ports, the configuration is as follows (below):
We are only able to configure an IP on one of the vlans.
When we configure an IP from another vlan for the data lif, it does not respond to a ping.
Does anyone have any idea what I'm doing wrong on the Cisco switch?

Our problem was fixed by the storage people. They changed the server end to trunk, and the encapsulation / etherchannel.
I like all the suggestions, and they probably helped out with the configuration getting this to work.
