• 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.

• 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.

• 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.

• vPC and VSS port-channel uplinks

  Hello Forum team!

  Currently I have a configuration of a couple of Nexus 5548UP in a field of vPC with a couple of Nexus 2248TP aircraft in a double scenario hosted for the access layer (FEX in a vPC also). Core/distribution, there are a pair of 6509 cluster VSS. Now I configured a regular port-channel every 5K to the VSS functionality and works as expected. My question is this: given that in the vPC a 5K is the main and the other is secondary, a configurable vPC for the uplinks to the VSS instead of a channel of regular port of each 5 K?

  In addition, configurations must be replicated manually on both Nexus 5 K? I'm in denial about this. I'm used to how VSS works.

  Thanks to the advanced guys!

  Hello

  You can use a vPC of the pair of Nexus 5 K to the VSS cluster. There is a white paper Cisco Catalyst 6500 VSS and Cisco Nexus 7000 vPC of interoperability and best practices that will in this. While the white paper is for Nexus 7000 are you interested to do probably is the configuration shown in Figure 2 and so the scenario and considerations are the same.

  On the Nexus switches with vPC there are still two control i.e. plans, the primary and secondary that you mention. For all the configurations that should be applied at the primary and secondary, you can manually configure on the two switches or use the synchronization of Configuration characteristic Nexus (see Configuration synchronization Operations for more details).

  He was 15-months we have looked at the function so probably things have changed, but following issues with our tests, and we were see reported here in the forum at this time, we decided not to use the config Sync feature. Outside all bugs, there are some operational changes to consider and then make sure that you are comfortable with how config-sync works before putting it in a production environment.

  Hi Joris,

  It is a known problem and is documented as a cosmetic bug internal. Logically speaking, CDP is not supported on etherchannel interfaces and 'sh cdp port-channel' command should not be available.

  The platform of 6500, although the "port channel show cdp neighbor" returns the result, it's just for convenience and does not mean that the CDP is supported on the port channels. In fact, if you try to enable CDP on port-channel on 6500, it generates an error:

  PO1 #int 6500 (config)

  6500(Config-if) #cdp en

  % CDP is not supported on this interface, or for this encapsulation

  If you run "debug cdp events", you can see the packets exchanged on the physical interface rather than on the port-channel. Correct way is to check the neighborship of the cdp on the physical interfaces.

  See you soon,.

• IOS NXOS VPC PORT channel

  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,

  http://www.Cisco.com/en/us/docs/switches/LAN/catalyst2960/software/release/12.2_53_se/configuration/guide/swethchl.html

  Even after doing this that I wouldn't say 100 percent, he would choose a link.

  I hope this helps!

  Thank you

• 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.

  http://KB.VMware.com/selfservice/microsites/search.do?cmd=displayKC & docType = kc & docTypeID = DT_KB_1_1 & externalId = 1006525

  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?

  As long as your NLB nodes are on the same vlan, you should be fine.

  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.
