About MDS 9222i config port-channel

dear everyone~
in project ,i need config MDS 9222i use 4 FCIP interface connect to 7606S 4 GE port for port-channel feature,but in MDS9222i i use port-channel commad ,cannot run。
how can i config it？

Hi Sun,
Ethernet PortChannels are not supported on MSM-18/4 modules and 9222i IPS modules.
You can place the fcip interfaces in a fibre channel port-channel instead.

MDS configuration for port channel

I've tried to set up the new FC port channel upload to a pair of MDS 9124s, but as I don't know enough about the MDS side I can't get the link to come up. Are there any references available anywhere that tell you blow by blow exactly how to configure the MDS side of the port channel? Or perhaps a sample working config?
Thanks

Simon,
A few items:
1) You are on 1.4.1i Balboa code
2) FI's are in FC switch mode as MDS 9124's don't support F-port channel (NPV/NPIV)
3) It's a lot easier the first time if you have matched speed sfp+ all around. Although, with the correct configs, unmatched speeds can be made to work.
If the FIs are in switch mode and your MDS is running a minimum 3.3 here are some configs that may help:
MDS side interfaces 4/11 and 4/12 are plugged into the UCS fc ports. First setup and ensure ISLs are working properly between UCS and MDS, then configure the port-channels
interface fc4/11
switchport rate-mode dedicated
switchport mode E
switchport trunk mode auto
no shutdown
interface fc4/12
switchport rate-mode dedicated
switchport mode E
switchport trunk mode auto
no shutdown
The UCS GUI Equipment -> Fabric Interconnects -> FI-A -> Set FC Switching Mode. This will cause both FI's to reboot into FC switch mode. This is VERY DISRUPTIVE, both FI's will reboot.
On the UCS CLI you should see this on the UCS fc ports connected to the MDS
cae-sj-ca3-A(nxos)# show running-config interface fc 2/1-2
!Command: show running-config interface fc2/1-2
!Time: Wed Oct 20 16:49:39 2010

interface fc2/1
switchport mode E

interface fc2/2

Until you have VSAN trunks enabled, make sure the ports on the UCS and MDS are in the same VSAN. VSAN 1 for example.
Once you have working ISLs, then proceed to turn them into port-channels and enable VSAN trunking. Start with the MDS
Create a channel group, it should look like this
cae-sj-9506-1# show run interface port-channel 3
!Command: show running-config interface port-channel 3
!Time: Wed Oct 20 17:06:01 2010
version 5.0(1a)
interface port-channel 3
channel mode active
switchport mode E
switchport rate-mode dedicated
switchport trunk mode auto <-- VSAN trunking
Enable VSAN trunking on the MDS ISL interfaces, it'll look like this:
cae-sj-9506-1# show run interface fc 4/11-12
!Command: show running-config interface fc4/11-12
!Time: Wed Oct 20 17:07:05 2010
version 5.0(1a)
interface fc4/11
switchport rate-mode dedicated
switchport mode E
switchport trunk mode auto
no shutdown
interface fc4/12
switchport rate-mode dedicated
switchport mode E
switchport trunk mode auto
no shutdown
Add the channel group information to the MDS ISL interfaces:
Enter configuration commands, one per line. End with CNTL/Z.
cae-sj-9506-1(config)# interface fc 4/11-12
cae-sj-9506-1(config-if)# channel-group 3 force
fc4/11 fc4/12 added to port-channel 3 and disabled
please do the same operation on the switch at the other end of the port-channel,
then do "no shutdown" at both ends to bring it up
cae-sj-9506-1(config-if)# show run interface fc 4/11-12
!Command: show running-config interface fc4/11-12

Create the SAN port channel on the UCS side
SAN -> SAN Cloud -> Fabric A -> FC Port Channels -> Create Port Channel
After you create the SAN port channel in UCS, make sure and enable it. I also bounce the MDS port channel at this point.
If all is correct, in a few agonizing minutes, the port-channel will be formed and passing data.

Again, make sure you have the ISLs up an running first before configuring the port-channels. It makes troubleshooting much easier.
Let me know if you need any help.

Storm Control on Port-Channel Interfaces (6500 platform)

Hello.
I cannot find it anywhere in the documentation for the Cisco 6500 platform (IOS). The question is this: When calculating the percentage of broadcast passing through a Port-Channel interface, which total bandwidth figure is used by the switch? For example:
a. If we have a bundle of 4 Gig interfaces in a PortChannel with Storm-Control applied, the threshold will be calculated over 4Gb/s or 1Gb/s?
b. If the same PortChannel for some reason loses 2 of the uplinks in the Bundle, will the calculation be made over 4Gb/s, 2Gb/s or 1Gb/s?
Thanks!

Hi Leo,
I can't find any reference to this at the moment, but my thoughts are that it will be based on a single member port of the port-channel.
Remember that a port-channel is logically a single link and so a broadcast is only sent on one of the links of the port-channel and not all of them. The decision as to which link is used will be the same as for any other frame i.e., the broadcast address is used within the hashing calculation to choose the physical port.
If the storm-control values are determined based upon the aggregate bandwidth, and changes as links are added/removed from the agregate, then the suppression threshold values for link carrying the broadcasts is never going to be correct.

Determine NIF port used by VIF when configured in a port-channel

I have recently just watched an excellent Cisco Live video on UCS performance troubleshooting which demonstrated how to trace network traffic within Cisco UCS. The speaker made a comment though, in order to determine which NIF is used by a VIF when port-channels are used between the FEX and FI there are different commands to run. Have to review the hash result or something he said. Unfortunately he never went into what these commands were.
So when we have veths pinned to port-channels instead of HIFs and NIFs, what commands will show which path is being used?

Can I join Layer 2 MEC port channel with 10G SR and LR together?
We are thinking of using VSS setup.
VSS with Server Farm switches.
VSS sw1 and sw2 are in different building.
in order to save cost..
Server farm 1 with VSS sw1 will use 10G SR.
Server farm 1 with VSS sw2 will use 10G LR.
But I need to bundle that 10G SR and LR together to form L2 MEC..
Thanks,

hi John,
yes you can
one thing you need to check is that the qos scheduling match on the interfaces , they can differ depending on what cards they are on .....ie below (in bold)
even if they dont match -- there is a command to ignore this in etherchannel formation -- i can dig up if you need.

Configure 2801 for 15 channel PRI

I'm new to configuring PRI's so excuse me if there is an obvious answer to my question. I recently purchased CUCM Business Edition and a 2801 router. I've configured the CM and the router and now have outbound calling working but cannot call in to any of the DID's. On the controller I did
pri-group timeslots 1-15 service mgcp

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.

WAAS Port Channel Configuration

In the recent weeks we got some reports that CIFS writing performance to NETAPP OnTap 7.3 filer was degraded for WAAS accelerated connections. NETAPP OnTAP 7.2 and native Microsoft filers were running fine. In our Testlab we could correlate this issue with the port channel setup on our WAAS devices. With round robin (standard setting) the CIFS writing perforamce was poor. By switching the port channel loadbalancing to src-dst-ip-port the performance was excellent.
Is there any known best practices recommendation for port channel configuration on WAAS devices?
Many thanks in advance, Peter.

The best practice depends on your network. Most deployments are fine with the default round robin configuration for port channel on the WAE. But I have encountered some installations where the configuration had to be changed in order to avoid out of order packets causing slow performance (like, if there is a firewall between the WAE and the server).

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.

Are there any ristrictions with shaping on Port-channel interfaces?

Hi,
Traditional QoS will not work for etherchannels. Please read to find suitable config for your case.

"The `Inline' mode also supports `Port-Channel'" ?

Referring to this document:
http://www.cisco.com/en/US/solutions/collateral/ns340/ns517/ns224/ns377/deployment_guide_c07-490578.html
it states:
"The `Inline' mode also supports `Port-Channel', which enables load-balancing and `high-availability' should one of the physical link fails"
is this true? I have a WAVE-474 which comes with 1 onboard port and 2 inline ports. Can you configure those 2 inline ports in a port channel and then use it with WCCP? I don't believe you can. Not sure what the document is referring too.
I also have WAVE-574's and that one can do port-channel using two onboard GIG interfaces + WCCP.

Hi Roman,
Your judgement was right. You can not configure inline interface in a port channel configuraiton.
Here is the output from wae-612 running 4.1.5c . You will see that there is no option for port channel / channel-group with inline interface.

Nexus 1000v port-channels questions

Hi,
I’m running vCenter 4.1 and Nexus 1000v and about 30 ESX Hosts.
I’m using one system uplink port profile for all 30 ESX Host; On each of the ESX host I have 2 NICs going to a Catalyst 3750 switch stack (Switch A), and another 2 NICs going to another Catalyst 3750 switch stack (Switch B).
The Nexus is configured with the “sub-group CDP” command on the system uplink port profile like the following:
port-profile type ethernet uplink
vmware port-group
switchport mode trunk
switchport trunk allowed vlan 1,800,802,900,988-991,996-997,999
switchport trunk native vlan 500
mtu 1500
channel-group auto mode on sub-group cdp
no shutdown
system vlan 988-989
description System-Uplink
state enabled
And the port channel on the Catalyst 3750 are configured like the following:
interface Port-channel11
description ESX-10(Virtual Machine)
switchport trunk encapsulation dot1q
switchport trunk native vlan 500
switchport trunk allowed vlan 800,802,900,988-991
switchport mode trunk
switchport nonegotiate
spanning-tree portfast trunk
end
interface GigabitEthernet1/0/18
description ESX-10(Virtual Machine)
switchport trunk encapsulation dot1q
switchport trunk native vlan 500
switchport trunk allowed vlan 800,802,900,988-991
switchport mode trunk
switchport nonegotiate
channel-group 11 mode on
spanning-tree portfast trunk
spanning-tree guard root
end
interface GigabitEthernet1/0/1
description ESX-10(Virtual Machine)
switchport trunk encapsulation dot1q
switchport trunk native vlan 500
switchport trunk allowed vlan 800,802,900,988-991
switchport mode trunk
switchport nonegotiate
channel-group 11 mode on
spanning-tree portfast trunk
spanning-tree guard root
end
Now Cisco is telling me that I should be using MAC pinning when doing a trunk to two different stacks , and that each interface on 3750 should not be configured in a port-channel like above, but should be configured as individual trunks.
First question: Is the above statement correct, are my uplinks configured wrong? Should they be configured individually in trunks instead of a port-channel?
Second questions: If I need to add the MAC pinning configuration on my system uplink port-profile can I create a new system uplink port profile with the MAC pinning configuration and then move one ESX host (with no VM on them) one at a time to that new system uplink port profile? This way, I could migrate one ESX host at a time without outages to my VMs. Or is there an easier way to move 30 ESX hosts to a new system uplink profile with the MAC Pinning configuration.
Thanks.

Hello,
From what I understood, you have the following setup:
     - Each ESX host has 4 NICS
     - 2 of them go to a 3750 stack and the other 2 go to a different 3750 stack
     - all 4 vmnics on the ESX host use the same Ethernet port-profile
          - this has 'channel-group auto mode on sub-group cdp'
     - The 2 interfaces on each 3750 stack are in a port-channel (just 'mode on')
If yes, then this sort of a setup is correct. The only problem with this is the dependance on CDP. With CDP loss, the port-channels would go down.
'mac-pinning' is the recommended option for this sort of a setup. You don't have to bundle the interfaces on the 3750 for this and these can be just regular trunk ports. If all your ports are on the same stack, then you can look at LACP. The CDP option would not be supported in the future releases. In fact, it is supposed to be removed from 4.2(1)SV1(2.1) but I still see the command available (ignore 4.2(1)SV1(4) next to it) - I'll follow up on this internally:
http://www.cisco.com/en/US/docs/switches/datacenter/nexus1000/sw/4_2_1_s_v_2_1_1/interface/configuration/guide/b_Cisco_Nexus_1000V_Interface_Configuration_Guide_Release_4_2_1_SV_2_1_1_chapter_01.html
For migrating, the best option would be as you suggested. Create a new port-profile with mac-pinning and move one host at a time. You can migrate VMs off the host before you change the port-profile and can remove the upstream port-channel config as well.
Thanks,
Shankar
