Total speed for port-channel when config speed 1000 in nexus5548?
hi ,everyone.
now i connect cisco 6509 and nexus 5548up using two 1000M link,and i want to binding two link as port-channel,
because 5548up port is 10GE ,cisco 6509 port is 1GE,i config speed 1000 in the nexus5548 ethernet port ,and i find
that speed 1000 commade auto config in interface port-channel,so i want to know the total speed in this port-channel
is 1000M or 2000M when the port-channel speed config as 1000?i appreciate for your help!!
the topology like this:
1000M
6509 port-channel speed 1000M nexus5548UP
1000M
hi again
The speed of the links and portchannel is 1000M but the bandwith of the portchannel is 2000M

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?
ThanksSimon,
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
version 4.2(1)N1(1.4)
interface fc2/1
switchport mode E
no shutdown
interface fc2/2
switchport mode E
no shutdown
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
!Time: Wed Oct 20 17:07:39 2010

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.
cae-sj-ca3-A(nxos)# show interface san-port-channel 1
san-port-channel 1 is trunking
Hardware is Fibre Channel

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. -

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,
Johnhi 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.

Port Channel Downtime/Convergence time when adding interfaces
I am looking to add a 3rd and maybe a 4th physical port to an existing port channel as we are running out of capacity, at peak we are pushing around 1.3Gb over the 2Gb channel and we are expanding services out of this location. My question is this, what will the downtime and convergence time be on the port channel when i add in the extra interfaces. Will i drop packets, will my customers notice any service disruption ?
Currently configured as follows:
interface Port-channel2

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?
thinks~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.

My company just purchased a Nexus 5548. I've been fooling around with the configurations and just getting familiar with this equipment. I've already configured a port channel using 2 10gig ports on our 3850 and its working fine.
Now, I'm trying to configure a second port channel with our 6509 1gig ports. Ports comes up. But I cannot communicate between these 2 devices.

Nexus 6K: Port-Channel Load-Balance
Hi all,
I configured "port-channel load-balance ethernet source-dest-mac" on Nexus 6001. But when I use "show run all | in load-balance", it displays module 1 and module 2 are still using source-dest-ip for port-channel load-balance. And for command "show port-channel load-balance" and "show port-channel load-balance forwarding-path interface", it still shows switch using MAC for hash algorithm. The NXOS is 6.0(2)N1(2a).
Does anybody know:
- What is the function of "port-channel load-balance ethernet source-dest-ip module" and in which situation this command will be effective?
- It shows "port-channel load-balance ethernet source-dest-ip module" command for both module 1 and 2. Module 1 is N6K Supervisor and module 2 is 4xQSFP Ethernet Module. Is it possible to set different load-balance algorithm to these 2 modules?

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. -
"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.

i havea single FEX 2232 single homed to nexus 5020 via port-channel. at the FEX 2232, i connected a server which have 2 X CNA and running two vlans: vlan 200 for ethernet and vlan 300 for FCoE.
i connected the server to the single fex via port-channel and allowed vlan 200 & 300. at the N5K i bounded single vfc interface to this port-channel.
when i am issuing the show flogi database i see only single PWWN.
as i understand, a single vfc interface can only see single PWWN, is this correct ?
if it does, how can i have my setup running in a way that ethernet traffic will used port-channel and for fcoe traffic i will see two PWWN ?
please advise,
Avi.It is not necessary to create another FCoE Vlan if the logins are coming on the same n5k. If there is a requirement for multiple fcoe logins on the same n5k, then it will need to be single link port channels instead of multiple links in the port channel. That way we acquire the ability to bind each physical port via port-channel into a separate vfc. In your case ideally you can have two n5ks with two n2232s single homed to each n5k and the server dual homed with 1 port each connected to two separate 2232s in active-active teaming. That way you can bind the physical interfaces into single virtual port channel on the respective n5ks. at that point, you can separate the san traffic into different vsan/vlan and make sure you dont trunk the fcoe vlan over the vpc peer link.
Hope this helps, Vinayak. -
RWB - No adapter registered for this channel (JDBC)
Hi Experts,
All my JDBC communication channels have the following log in RWB:
No adapter registered for this channel
When executing an interface, SXMB_MONI shows:
Object not found in lookup of SapXIJDBCAdapterService
We have aready performed a CPACache refresh as mentioned on another threads but the problem persists.
I performed dummy changes in the CC and even created a new one but the log still remains the same.
Please advise what else can be done to solve the issue. We are using PI 7.1.
Regards,
DanielaHello,
Try checking in the Netweaver Administrator if the JDBC service is running?
There is also a dependency of modules in between the SapXIJDBCAdapterService and SapXIFileAdapterService. Please check that the File Adapter service is started also.

About n1000v with port channel
there is a n1000v connected to multiple upstream switches in the customer's production environment.
the following is from the Cisco Nexus 1000V Interface Configuration Guide, Release4.2(1)SV2(2.1).
You use vPC-HM mode to create a port channel when the switch is connected to multiple upstream switches
that are not clustered.
my question is,
can I use LACP with multiple upstream switches that are not clustered?
can I use LACP with multiple upstream switches that are stacked?
if I stack multiple upstream switches,does it mean clustered?
thanks.Hi,
See some of the guidelines:
Guidelines and Limitations
Port channeling has the following guidelines and restrictions:
•All ports in the port channel must be in the same Cisco Nexus 1000V module; you cannot configure port channels across Cisco Nexus 1000V modules.
•Port channels can be formed with multiple upstream links only when they satisfy the compatibility requirements and under the following conditions:
–The uplinks from the host are going to the same upstream switch.
–The uplinks from the host going to multiple upstream switches are configured with vPC-HM.
•You can configure multiple port channels on a device.
•After you configure a port channel, the configuration that you apply to the port channel interface affects the port channel member ports. The configuration that you apply to the member ports affects only the member port where you apply the configuration.
•You must remove the port security information from a port before you can add that port to a port channel. Similarly, you cannot apply the port security configuration to a port that is a member of a channel group.
•You can configure ports that belong to a port channel group as PVLAN ports.
•Any configuration changes that you apply to the port channel is applied to every member interface of that port channel.
•Channel member ports cannot be a source or destination SPAN port.
That said LACP should work on switches that are not clustered and meet the conditions above.
A stack is treated as one unit which means that would be like you have just one big chassis.
Stacking does not the same as clustering it works different. so if you stack them that would be a stack not a cluster

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).
