Microsoft NLB on a Port Channel
Hi people,
I read that static entry ARP is necessary to ensure the VIP created in Microsoft NLB cluster work properly with the network switch.
However, each of the two VM in my NLB cluster is connected to a vDS configured with tagging VLAN. I have several VLANs on a channel of the VDS service port.
Use of VLAN tagging/Port Channel make a difference in the procedure for setting up the static ARP entry?
Thank you
Michael
As long as your NLB nodes are on the same vlan, you should be fine.

Hello
I have a pair of Nexus 5 K in an area of the VPC and few 2960's as members of the VPC, with a port to the domain channel.
Topology is:
5K 1 and 5 K 2 in the area of the VPC
VPC 5 1 K and 5 K 2 to 2960
2960 a gi0/1 and gi0/2 in 1 port channel
Gi0/1 5 k 1, gi0/2 5 k 2
I know what I'm going to ask can be completely against the purpose of the VPC, but I'm looking for a way to promote gi0/1 for traffic, rather than balancing on gi0/1 and gi0/2. The reaon for this is I want to take advantage of the absence of loop that provides mail ORDER, but would also like to have a link primary and secondary, as the majority of traffic should in fact go through 5K 1, rather than 5 K 2.
Any suggestion is welcome.
Thanks in advance
Anthony
Hi Anthony,.
The Cisco NX - OS software load balance traffic across all operational interfaces in a portchannel by chopping the addresses in a numeric value that selects one of the links in the channel. Port channels provides default load balancing. It uses IP addresses, MAC addresses or layer port numbers 4 to select the port-channel-balancing link of the load. The port-channel load balancing uses the source or destination or port addresses, or both the source and ports or destination addresses.
You can configure the mode of load balancing to be applied to all port channels that are configured on all of the device, or the specified modules. Each module configuration takes precedence over the configuration of load balancing for the entire device. You can configure a single mode of load balancing for the whole device, a different mode for specified
modules and another mode of the other specified modules. You can not configure the port-channel load balancing method.
You can configure the type of balancing algorithm used. You can choose the balancing algorithm that determines which Member port to select for the evacuation traffic by looking at the fields of the frame.
Note: The mode of load balancing by default for layer 3 interfaces is the IP source and destination address, and the mode of the load balancing by default for non - IP interfaces is the source MAC address and destination.
The configuration mode, you can try different method of load-balancing,
port-channel - the balance of the load {dest-ip-port | dest-ip-port-vlan |}
destination-ip-vlan. destination-mac | destination-port | source-dest-ip-port | source-dest-ip-port-vlan. source-dest-ip-vlan. source-dest-mac | source-dest-port | Source-ip-port | Source-ip-port-vlan. Source-ip-vlan. source-mac | source-port} [number of the module]
To sum up: I can't tell which port would be chosen, it depends purely on image type you send with the combination method of load balancing.
After you change you know also from the command which link takes the traffic.
NEXUS2-SPAN # show the port-channel - the balance of the charge-transfer port-channel 71 src - ip 1.1.1.1 route dst - ip 2.2.2.2 VLANs 51 2 interface module
Module 2: Missing params will be substituted by 0.
Load balancing algorithm: src - dst ip-l4port
RBH: port id out 0xb0: Ethernet8/8
We can try also to rework the same NLB on the 2960 also. Is it purely depends on the algorithm of load balancing. Below is for 2960 balancing tweaking,
Even after doing this that I wouldn't say 100 percent, he would choose a link.
I hope this helps!
Thank you
Richard.

See the bandwidth for the Port-Channel on Powerconnect &; Force10
Reference Dell dear community,
Y at - it a command CLI or GUI to see how much bandwidth result after having done a port channel in some port Powerconnect and Force10? Suppose we have 4 port 1 Gb and do 4 ports with 1 port-channel. So actually in this channel port have a bandwidth of 4 GB.
In Cisco, with the command show interface port-channel 1, we get the result

The PowerConnect switches do not have the ability to show as much detail as the Force10 can. The RMON tables have an interface use %, what may be the closest we can do on the PowerConnect switch.
#show rmon statistics
I've seen some monitoring software which was able to question the switch via SNMP and get some information of bandwidth. However, this can be a bit inconsistent, according to which switch and what software is used.
The MIBs/OID can be downloaded with the software switch.

Hello
I need help, I'm setup CF port-channel between 9148 MDS and Cisco fabric Interconnect 6248 and the port-channel does not work. He said no operational members.
For the MDS, see configuration below:
NPIV #feature SW (config)
SW (config) #feature fport-channel-trunk
SW (config) #interface fc1/17-18
SW(config-f) force Group-channel mode # 63

SW (config) #no close
SW (config) #interface 63 port channel
SW(Config-if) F #switchport mode
SW(config-f) #switchport trunk-allowed vsan 1-2
SW (config) - #no close
Note: the ports are assigned to vsan 2
See the attached screenshots for interconnection fabric config
On the fabric of interconnections switchport mode are defined E. What I have to change to F. If yes where can I change since the option is not there in the UCS Manager?
have you added the VSANS on the UCSM as well?

MDS configuration for port channel
I tried to put in place the new download FC port channel to a pair of 9124 s MDS, but as I don't know enough on the side MDS, I can't the link to come. Are there references available anywhere say you blow by blow exactly how to set up the side MDS of the channel of the port? Or maybe an example of configuration work?
Thank you
I don't think it's possible to configure the fabric of interconnections, FC switch mode that only VAN is based on those. The only mode of switch that is taken in charge and possible to configure is the local network Ethernet switching mode.
I have configured the week last on a pair of 9124 s MDS and needed to activate the F port trunking and channeling Protocol feature by using this command
"feature fport-channel-trunk.

Configuration port-channel, DTP, disabling
Hi all
I had a problem on the day where I wanted to attach a pile of 3750 x 2 to the network, the core is a 6500.
There was a link configured for the core of the 3750 he had the configuration necessary trunk with BPDUFILTER active
at the end of the base he had the standard configuration of trunk. The link is on the rise and work.
Went to get a second battery for the heart link. Decided that DTC must be turned off at the end of the SWITCHPORT NONEGOTIATE battery
the normal chest on the port configuration on the port channel port joined. Then suddenly the newspapers went crazy and right now, I need
Spanning tree went crazy and started blocking areas of the network to avoid loops. There is STDS running in the network
I had similar errors to this % SW_MATM-4-MACFLAP_NOTIF
I pulled the battery cables and all services affected later came back.
I know that enable the BPDUFILTER option stops at the port to participate in STP.
Please could someone confirm due to the incompatibility of the config on these ports it has this problem or is there something I missed here
Thank you mnay
The BPDU filter is the root of the problem.
You can't have two active rising running without creating a loop, unless they run into a PaGP/LACP-EtherChannel configuration. By having one or two links running with a filter BPDU, spanning Protocol tree on the 6500 didn't know that a link had to be in a deadlock state and he was panicked when MAC addresses on the stack of 3750 began to stir between interfaces.
3750 cross media - stack EtherChannel using LACP, so if you want the resilience of two connections without having to factor in the covering tree branches, it is a good idea to combine the two in a group of channels and have both the 3750 and 6500 treat them as a single logical connection.
If you want to keep them separated, you will need to remove the filters BPDU these ports and leave spanning tree figure things out properly.

Port-channel problem between fabric Interconnect and vPC N7K
Hi all
I have a problem with the Port Uplink channel between fabric interconnect with N7K using vPC
It's my network for the UCS deployment topology
N7K I configured vPC for red link and green linkto the fabric Interconnect A I has configured the Port-Channel with Member is Port 1 and Port 2, uplink is red link. Interconnection fabric B, I have configured the Port-Channel with Member's Port 1 and Port 2, uplink's green link.
The interface port-channel on N7K show is good, each port-channel upwards and have all members. But the fabric Interconnnect, when I see in the UCS Manager, the status of the Port-Channel on Fabic A and fabric B dysfunction not more info: no operational Member. Although all the link is a link to the top and I've got the status of the Port Channel is enabled in the UCS Manager. When I see the properties Port 1, Port to Port-Channel 2, I see the number of members status is: individual. This means channel port is not up and no member in this configuration. I want to using the port-channel load balance and more bandwidth for the uplink of 20Gig. I don't understand why?
Please help me solve this problem, I have to send the screenshot of UCS Manager when I show the status of the Port-Channel and Port-member in port-channel to reach items.
Can someone help me solve this problem, thanks a lot. References, please include elements for more details on the fault.

Once in production, when the addition of cables in a PortChannel from fabric between the IOM and a FI, first had to be re - ack frame? (so that we will have the chassis package downtime). Or rather, as is a Port-Channel cables are detected automatically, so that it is not necessary to re - ack, and so there is no downtime in all... one that is the correct statement?

Hello
I hope someone can help with this,
I have a Setup with 2 Nexus of 5548 connected via a link of vpc peers and a keepalive, these two nexus switch have a link of standard VPC to a 6500 upstream. It works fine,
Then, there are several native FC connections of the 5548 to of 6248. I know that there is the possibility to configure the channel port of CF on the UCS 2.0 but it is possible to link 5548 CF interfaces in a port channel san through a vpc between the nexus of 5548.
so, for example, I can port-channel which follows through a vpc or is a channel of port san, limited to the same nexus only switch ports.
Fc1/31 & fc1/32 fabric sent to-> NX5K - 1 Port fc1/31 & NX5K - 2 Port fc1/32 (san port-channel 10 on a VPC)
Fabric B fc1/31 & fc1/32 passed to-> NX5K - 1 Port fc1/32 & NXFK - 2 Port fc1/31 (san port-channel 11 on a VPC)
Thank you

It is not possible. VPC is the only Layer 2 ethernet port channel. Port channel San cannot be built through vpc

IPS Inline Mode Interface - you can use a port channel?
Hello
I am trying to determine if you have a 2-gig Layer 3 Port channel through a 4260 IPS appliance. See the attached diagram. Is this possible?
The customer, I work with would prefer not to enter this cost equal to Port-Channel 1 gig of links (I don't think that there is a difference in performance...) However, I think that if they want the device inline, as the diagram shows - they will have to break the port-channel. Is this a correct assumption?
Thank you
Brad
Asymmetric traffic will prevent the sensor works best, he is capable. There is a configuration that can be done to allow the detector deployed in an asymmetrical environment, BUT it can affect the ability of the sensor to detect attacks, allows through evasions which would have been prevented and will not affect general performance of the sensor.
If running in unbalanced mode should be avoided if possible. BT in cases where it cannot then the sensor always allows with degraded functionality.
Traffic spikes above what the sensor can manipulate at will cause ignored packets. There is no help for too much traffic.
The relief you talk I guess is the bypass function. The bypass feature does not affect during the subscription of the sensor. The bypass feature will only kick if the analytical engine crashes due to a bug.

Setting port channel between UCS - FI and MDS 9124 (Mode F)
Dear team,
We tried to create the channel of port between UCS FI and MDS 9124
But the port channel do not take action in mode F on MDS 9124
FI is in host FC end Mode
We have allowed FC uplink on FI trunking
We have activated NPIV on MDS
We have activated the MDS trunk
FI and MDS in default VSAN
To check that we have changed the way FI FC channels mode and switch port became active, but in E mode
When we enabled CF trunking of uplink on the port mode FI channels and FC Switching became active in mode TE
but in both cases above, showflogi database shows WWPN of SAN alone does not have the any fi.
How to achieve this?
Have read that no need to change the mode switching mode of CF swicthing and keep FC Endhost way
SO how to channel ports with mode F MDS and FI (Display Mode as NProxy)
What is it has nothing to do with the MDS NX - OS version? (https://supportforums.cisco.com/thread/2179129)
If yes how to put as license for ports came with the camera and we don't have any CAP/PAK or license file as she came
with license
Also, we saw 2 files available for download (m9100-s2ek9-kickstart - mz.5.2.8 .bin and m9100-s2ek9 - mz.5.2.8 .bin b b) to use
Thanks and greetings

Hi Jo Bo.
What version of the software if your MDS race?
On your UCS do connect nxos and show ficelleStringString ficelleT inteface and find the mac address.
It is possible that you could be hitting the bug below. If this is the case, you may need to update the firmware on your MDS.

However, you will notice that the two ports Gigabit (1 channel Port on this switch) are ORANGE... which means BLOCKED... .and this has been verified when I ran see the spanning tree on this switch
If it's supposed to happen?
Yes, even if these links were green in your portchannel LACP always would play you a loop, for this purpose, he blocked because of the fact that you have more links (aggregate bandwidth) between other switches so it is allowing more transmission between.
