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.

Sultan,
This is a recently found issue and is fixed in UCSM 2.0.3a version .
http://tools.cisco.com/Support/BugToolKit/search/getBugDetails.do?method=fetchBugDetails&bugId=CSCua88227
which got duped to CSCtz21585
It happens only when following conditions are met
FI in End host mode
FC uplinks are configured for portchannel + trunking
Certain link event failures ( such abrupt power loss by upstream MDS switch )

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
JoseHi 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

Port-channel Problem between Fabric Interconnect and N7K vPC
Dear all,
I have a problem with Port-channel Uplink between Fabric Interconnect with N7K using vPC
This is my network topology for UCS Deployment
In N7K I has configured vPC for red link and green link, at Fabric Interconnect A I has configured Port-Channel with member is Port 1 and Port 2, uplink is red link. At Fabric Interconnect B, I has configured Port-Channel with member is Port 1 and Port 2, uplink is green link.
The show interface port-channel on N7K is good, every port-channel is up and have all member. But At Fabric Interconnnect, when I see on UCS Manager, the status of Port-Channel on Fabic A and Fabric B is fault with Additional Info: No operational member. Although all link is link up and I has status of Port-Channel is enable on UCS Manager. When I see the Properties of Port 1, Port 2 on Port-channel, I see the membership status is : individual. This mean port-channel is not up and no membership in this configuration. I want to using port-channel for load balance and plus more bandwidth for uplink to 20Gig. I don't understand why ?
Please help me resolve this problem, I has send the capture screen of UCS Manager when I show status of Port-channel and Port-member in port-channel in attach items.
Anyone can help me to resolve this, thanks you very much. Please reference attach items for more detail about fault.
Thanks,
Trung.Thanks Matthew very much,
I has resolved this problem. The reason of problem is miss match protocol of port-channel between N7K and Fabric Interconnect. The Fabric Interconnect always use LACP protocol, but N7K using Port-channel mode on, that why the port-channel failed. I has configured LACP for port-channel in N7K, it has resolved the problems.
Thanks,
Trung. -
Routing issue between Cisco device and Virtual machine
Hi Guys,
We have two local subnets in a virtualized environment, subnet 1 has a VM operating as a firewall, we would like all traffic for subnet 2 to go via VM on subnet 1, this will police traffic on subnet 2 and then reroute.
The infrastructure involved comprises,
Internet Edge Switch -> ASA -> Core Switch -> IBM Flex chassis
The Internet edge switch is directly connected between the ISP routers and the Cisco ASA firewall pair (A/S). The ASA is then connected to the Core switch. Connected from the core switch is an IBM Flex chassis, via a port channel (all vlans allowed)
The local subnets in question are as follows:
Vlan 101 (10.1.1.0/24)
Vlan 102 (10.2.1.0/24)
The VM in question has two NIC cards having IP address of both subnets.
NIC 1: 10.1.1.1
NIC 2: 10.2.1.1
We would like packets destined for 10.2.1.1 to land on 10.1.1.1 IP address. At the moment traffic for each vlan routes from the outside to their respective local subnets successfully, what we are having difficulty with is directing traffic for subnet 2 via subnet 1 VM firewall.
At the moment we have tried adding a static route on the core switch but it didn’t work
ip route 10.2.0.0 255.255.255.0 10.1.1.1
I will appreciate if you could share your knowledge and guide me how to achieve this goal.
Thanks in advance :-)Hi,
I think for this to work you need a transit vlan between the VMs and the core switch. So, if you have 2 vlans on the VM (101 and 102) you use the VM switch to route between the vlans and in order to go outside the local vlans you would use the core switch. In this scenario you would not have an SVI (layer-3) interface on the core. The only thing that core will have is the layer-2 vlans (101 and102). You would than need a static route on the core switch to point to the transit vlan on the VM side.
so, for example, if the transit vlan is vlan 110 and the ip is 192.168.1.0/24
on the core you have static routes:
ip route 10.1.1.0/24 192.168.1.2 (VM side)
ip route 10.1.2.0/24 192.168.1.2 (VM side)
You also need an SVI for vlan 110 with ip address 192.168.1.1/24 on the core.
on the VM you need a default route to point to the core (192.168.1.1).
Is this what you are trying to do?

Routing issue between Cisco Nexus and Cisco 4510 R+E Chassis
We have configured Cisco Nexus 7K9 as core and Cisco 4510 R+E as access switches for Server connectivity.
We are experiencing problem in terms of ARP learning and Ping issues between Cisco Nexus and end hosts.Hi,
So you have N7k acting as L3 with servers connected to 4510?.
Do you see the MAC associated with failing ARP in 4510?. Is it happening with all or few servers?. Just to verify if it is connectivity issue between N7k and 4510, you can configure an SVI on 4510 and assign address from same raneg (server/core range) and perform a ping.
This will help narrow down if issue is between server to 4510 or 4510 to N7k.
Thanks,

Score Issues between Captivate 4 and 5
Hi Everyone,
We are noticing an issue between Captivate 4 and 5 and we can't seem to figure out what is going on, this issue is with Captivate modules that have no quiz and the completion status is based only on a % of slide views. We publish as SCORM with complete/incomplete and report percent.
With these types of modules created in Captivate 4, the LMS would record a completion and a N/A score. Now, for those created in Captivate 5, the LMS receives a 0% score and the completion. Our end users are really confused as to why they see a 0%. Any ideas on what may be causing this? The LMS is Taleo Learn, formerly Learn.com's LearnCenter.
Any assitance would be greatly appreciated.
Thanks,
ConnorIf you can't download any old versions by logging into your account then clearly these have been discontinued. Your best bet is ask somebody to lend you their CD/DVD which you can copy for your safe keeping.
Old products are always discontinued and that is why you should always buy them on a CD/DVD so that they can installed whenever you have a new system or you have a system crash.
Good luck. -
What is the difference between AK Repository and MDS repository?
HI all,
I am pretty new to OA framework . Can anyone let me know the difference between AK Repository and MDS repository?
Thanks
-ChackoAK Repository stores the page flows developed using the AK Developer. This is outdated and Oracle only supports for backwards compatibility.
is correct only if looked at from OAF perspective, for many other products/modules, AK dictionary is still the source the truth for metadata.Thanks

Interoperability issues between Nexus 5k and HP storageworks (8/20q)
Hello community,
I am trying to get a VM host and a windows server to connect to their storage across a nexus and HP (Qlogic) fabric switch. This is currently having issues with the VM host unable to see the datastores, possibly due to interoperability between Cisco and HP (Qlogic)
I have configured and tested the connectivity using only the cisco nexus and this worked, I then tested it using only the HP fabric switch (HP 8/20q) and this also worked.
However, when using the HP and Cisco Nexus as shown in the attached diagram, things stop working.
The connection is using Native Fibre channel, On the Cisco side I performed the following steps
Configured the Nexus with Domain ID 10 and the HP with Domain ID 20.
Connected the 2 fabric switches on fc1/48 (Cisco) and port 0 (HP) and confirmed that the ISL came up (E_port 8G), I confirmed connectivity using fcping both ways.
I connected the SAN to the Nexus and the servers to the HP
Configured VSAN 10
Added interfaces fc1/41 to 48 in VSAN 10
Created 2 zones ( ESXI and Windows)
Added the PWWN for the ESXI server and the MSA2040 to the ESXI zone
Added the PWWN for the Windows 2k8 server and MS2040 to the Windows zones
Created zoneset (Fabric-A) and added both the above zones in it
Activated the FABRIC-A zoneset
The result is that the zones and zoneset are synchronised to the HP switch .I confirmed that I was able to see the servers and SAN WWN in the correct zones on the HP.
From the 8/20q switch I am able to fcping the SAN, Nexus and servers, however the Nexus is only able to fcping the SAN and the HP, it returns a “no response from destination” when pinging the servers.
I have added the FCID for all the units in the same zones to see if it makes any difference to no avail the result seem to be the same. I have gone through various Nexus/MDS/HP/Qlogic user guides and forums; unfortunately I have not come across any that shows this specific topology.
source for HP user guide is here: http://h20565.www2.hp.com/hpsc/doc/public/display?docId=emr_na-c02256394
I’m attaching the nexus config and partial view of the “show interface brief” showing the fibre channel port status

Any help and advice would be greatly appreciated. thanks in advanceHi all, after much reading, Walter Dey provided the hint to put me on the right track.
By default the Nexus 5k is in interop mode 1. However, one of the requirement for this to be "interoperable" with other vendor the FCDomain ID in the entire fabric needs to be between 97 and 127 as stated in the Cisco website.
http://www.cisco.com/en/US/docs/storage/san_switches/mds9000/interoperability/guide/ICG_test.html
Another issue that had me and my colleague scratching our heads, was that we were seeing high level of CRC errors on the ISL interfaces. This was caused by ARBFF settings mismatch between the Nexus and the HP. This was resolved by ensuring that the ARBFF setting on the HP was set to false and the command "switchport fill-pattern ARBFF speed 8000" is configured on the ISL interface linking the 2 switches. (note that Cisco's default setting for the ports is IDLE, until this is changed the link will not stabilise)
Thanks for all your help guys. -
Etherchannel issue between 3750 stack and WS-CBS3012 for IBM blade centre
Hi,
We are trying to configure Etherchannel between four ports of cisco 3750 stack(2ports from one switch of stack and two ports from another switch of same stack). We are facing issues with this setup. The ports in WS-CBS3012 are going to err disable mode.
Is there any limitations associated with such a cross-stack etherchannel configuration. Please suggest if there is any particular sequence of configuration involved.
Switch1 in stack
int gi 3/0/3
switchport mo trunk
switchport trunk allowed vlan 10-30
sw tr en dot1q
channel-group 1 mode on
spanning-tree guard root
switch 2 in stack
int gi 3/0/3
switchport mode trunk
switchport trunk allowed vlan 10-30
sw tr en dot1q
channel-group 1 mode on
spanning-tree guard root
int port-channel 1
switchport mode trunk
switchport trunk allowed vlan 10-30
sw tr en dot1q
channel-group 1 mode on
spanning-tree guard root
in WS-CBS3012 ports are configured with trunk,allowed vlan and etherchannel configuration with mode on.
With Regards,
Madhan kumar GHi,
The commnad "no spanning-tree etherchannel guard misconfig" on WS-CBS3012 resolved the issue.

Port-channel issue over Ciena DWDM
Hi all,
I'm currently working on an issue encountered on a DC.
We currently use 2 3750 stacks (1 in each DC), connected with a Po.
We use dark fiber between each DC, so we have a Ciena DWDM transponder on each side.
The problem is that, if we have an issue on the inter-DC fiber, the Ciena interface on the 3750 side is still up. Using LACP on the Po, the issue can be detected in about 3 X 30 sec = 90 sec.
Before the issue is detected by LACP, the impacted port-channel interface is still used by the Po, which can cause big issues.
I thought use an EEM applet in order to monitor the CDP neighbor on each interface, and exclude the interface from the Po till the CDP neighbor is down, but the CDP timers are even bigger (180 sec hold-time).
Is there any way to address this problem, other than UDLD ?
In our others DC, we have two NX7K on each side, and we are able to use LACP with fast-rate, but this is not available on 3750...
Thank you very much !the best way to use pair of transponders on each side in protection group.

We have two Cisco ASA 55XX Firewalls and both are in HA (Active/Standy). Two ports from each Firewall is connecting two ports of Nexus 5K Switch and running port channel between Firewall & Nexus Switch and port-channel is UP. And Switches having back to back connection with allowed all VLAN trunk port.
FW01 ----------------- SW01 (Two ports with Port channel)
FW02 ----------------- SW02 (Two ports with Port channel)
I have VLAN 10 with IP Subnet 10.10.10.0/28
SW01 : 10.10.10.2
SW02 : 10.10.10.3
HSRP IP : 10.10.10.1
FWs : 10.10.10.4 & 10.10.10.5
Firewall Default Gateway : 10.10.10.1
Problem : I am not able Ping Firewall IPs from Nexus Switches. When I checked ARP table in Nexus Switch; I have observed that Firealls two IPs having same MAC address; when I checked that MAC address in the Firewall; that MAC address is Port channel interface MAC address.
This is issue (two IPs learing same MAC address) from ASA.
How to fix this issue ?
Thanks
VenkatHi,
What version of IOS are you running on the ASAs?
see table-12-3 in this link:
http://www.cisco.com/c/en/us/td/docs/security/asa/asa84/configuration/guide/asa_84_cli_config/interface_start.html
Also, since the 4500x are in VSS mode, you need to bundle one link from each switch and use LACP.

Issues between power, usb and airport?
Well, after having my new MacBook Pro for only a couple of weeks, I've come to the conclusion that there are some pretty weird issues between the power manager, usb bus and airport (and from what I've read here, are pretty widespread issues). First, every time I charge the battery, my Logitech MX laser mouse stutters and jumps all over the screen (trackpad works smoothly though). If I turn off airport, the mouse works smoothly again. When the battery is done charging, the mouse will work smoothly again. Second, every now and then (when the mouse isn't connected) the trackpad will start to stutter and jump all over the screen. When this happens, I've noticed that the graphics card is running slowly as well (expose stutters). Both of these issues can then be remedied by one of two actions, either plug something into a usb port, or turn off airport. I am also suffering from the missing first letter issue, which also seems to go away by disabling airport... So, since disabling airport most of the time is not an option, anyone care to take a guess as to how long it will take Apple to come up with a fix to these issues?
TM does not backup to a networked drive in the same way as a directly connected drive. A networked drive requires the creation of a .sparsebundle disc image file that holds the actual backed up files. So when you shift from direct to networked connection TM actually makes a different backup. This is unrelated to the actual type of port connection. So there's really nothing you can do to have TM use one backup for each type of connection used in your situation.

Port Channel Issue on Cisco 2960s-24ts
Hi All
Last week at a customer site we installed a 2nd 2960s 24 port switch to form a stack using flexstack cables, and the switch stack is working as expected as I can see a master switch and 2nd switch as a member.
For redundancy / resilience we decided to use port 24 on each switch over copper for trunk uplinks to our core switch. The issue that we're having is I can't ping the switch management address. I can however see the address in the arp table and the edge switch is visible when I run show cdp nei. As a work around I've shutdown one of the ports to the downlink from core to edge in order to ping the management address of the switch which is in vlan 1. I'd like to get the port-channel working on both sides for resilience.
ANY HELP IS APPRECIATED...
Core switch is a WS-C3750G-24TS-1U running software version C3750 Boot Loader (C3750-HBOOT-M) Version 12.2(25r)SEE4, C3750 Software (C3750-IPBASE-M)
Edge switch is a WS-C2960S-24TS-L running software version C2960S Boot Loader (C2960S-HBOOT-M) Version 12.2(53r)SE,C2960S Software (C2960S-UNIVERSALK9-M)
The config on the edge switch which goes to the core is :
interface GigabitEthernet1/0/24
description *****
switchport mode trunk
channel-group 6 mode on
end
interface GigabitEthernet2/0/24
description *****
switchport mode trunk
channel-group 6 mode on
end
interface Port-channel6
description ******
switchport mode trunk
end
The config on the downlink ports from the core to the edge:
interface GigabitEthernet1/0/20
description Edge
switchport trunk encapsulation dot1q
switchport mode trunk
channel-group 20 mode on
end
interface GigabitEthernet2/0/20
description Edge

switchport mode trunk
shutdown
channel-group 20 mode on
end
interface Port-channel20

endwhen using channel-group # on mode you must make sure the ports are on same duplex and speed setting
what happens when you use active mode? -
Connectivity issues between Cisco 2901 and Cisco SG300-52
Hello,
I am having some serious connectivity issues between the hosts in my LAN.
My LAN is based on a Cisco 2901 router and a Cisco SG300-52 port switch.
The issue that has been happening is that connections between hosts on the LAN (remote desktop, extended ping, etc) is very unstable, at some point I can see a 35% lost packets on an extended ping. This happens at any time of the day and from any host.
All hosts are on the same Vlan(default Vlan) and on the same subnet. Some hosts have fixed IP addresses (servers and network equipment) and others obtain their IP address trough a DHCP reservation established on the router (reserved with the MAC address of every host).
I can provide further details if needed, because this issue is very serious and I would really appreciate any insight or support.
Many thanks in advanced.
Sair Amer
EDIT: After doing every test we could think of, we finally found the reason behind this problem.
It turns out that the switch has problems handling communications between clients at different speeds, because most of the hosts connected were working at 100 Mbps but the servers were working at 1000 Mbps (and the communication between host and servers wasn't stable).
After manually setting the speed on all ports to 100 Mbps the problems have stopped.
Many thanks for you help on this issue.Building configuration...

Port-Channel Issue: SP-5-CANNOT_BUNDLE_LACP
I'm having an issue with the port-channel coming up. Right now it's "down down". I'm not really sure why. All other port-channels on the 6500's in VSS work fine. This one seems to be giving me an issue though.
