Xconnect 20Gb Port-channel over MPLS Possible?

Can anybody confirm if you can establish an Xconnect between two 20Gb port-channels (2x 10Gig bundle).  The core is 40Gig and running MPLS.  We have many gigabit pseudowires running over it already.
Our intention is to terminate 10Gig server traffic on 4900M's and then have a 20Gb Port channel trunk link into a 6500 (which is part of the MPLS cloud).   We would then issue the xconnect directly on the 20Gig port channel in order to traverse the MPLS Core.
Has anyone configured this before?  Are there any caveats to watch out for?  What sort of performance hit (if any does) xconnect functionality have on 10Gig Traffic.

Hi,
Yes it's supported but test it first (as always ;-) )

  • Port Channel over L2 MPLS links

    Hello.
    I was hoping that someone could over some suggestions on best practice or recommendations for configuring port channel to bundle to layer 2 MPLS links that we have.
    We have racks in two geographically separated data centres, each rack has a stack of Cisco 3850 switches, and there are two 100Mbps layer 2 connections linking these stacks together.  The links are provided by our supplier and runs over their core network (I can get more info on their setup if need be).
    I had initially just configured a simple port channel bundling the two ports on "Switch A", and the same on "Switch B".  However I have since noticed that one of the ports was put into error disabled state, and I have my doubts that we ever had 200Mbps throughput over the portchannel.
    The logs showed:
    UDLD-4-UDLD_PORT_DISABLED: UDLD disabled interface Gix/x/x, aggressive mode failure detected
    %PM-4-ERR_DISABLE: udld error detected on Gix/x/x, putting Gix/x/x in err-disable state
    How I understand is that one of ports recieved an unexpected (or incorrect) BPDU packet, and shut the port down as part of spanning tree process to stop a loop forming.
    For the time being I have removed the port channel config and re-opened all the ports, so I believe one of the ports is now in blocking state.
    Whilst redundancy for these links is great, ideally I would like to have the links bundled so I also get the benefit of higher throughput.
    Any thoughts are greatly appreciated.
    Thank you

    Hi,
    Thank you for your reply and suggestions.  I have been reading up on layer 2 protocol tunnelling and I'm not sure if this will work for us.  According to these guidelines for the catalyst 3550 (http://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst3550/software/release/12-1_19_ea1/configuration/guide/3550scg/swtunnel.html#wp1006657) it states:
    •If you enable PAgP or LACP tunneling, we recommend that you also enable UDLD on the interface for faster link-failure detection.
    •Tunneling is not supported on trunk ports. If you enter the l2protocol-tunnel interface configuration command on a trunk port, the command is accepted, but Layer 2 tunneling does not take affect unless you change the port to a tunnel port or an access port.
    •EtherChannel port groups are compatible with tunnel ports when the 802.1Q configuration is consistent within an EtherChannel port group.
    (maybe its a different and is supported on 3850's)
    Also, I cant use layer 3 over this link as I am looking to extend VLANs over the link so devices and virtual machines in each of the datacentre are in the same subnet and broadcast domain.
    I will speak with the supplier to see what they are willing to do.
    Thanks again.

  • UCS - san-port-channel over vpc

    Hi,
    I'm hoping someone can help out with this,
    I have a setup with 2 Nexus 5548's connected over a vpc peer link and a keepalive, These two nexus switch's have a standard VPC connection to an upstream 6500. this is working fine,
    Then there are multiple native FC connections from the 5548's to 6248's. I know there is the option to configure FC port-channel's on the UCS 2.0 but is it possible to put fc interfaces of the nexus 5548 into a san port-channel across a vpc between the the nexus 5548's.
    so for example, can i port-channel the following across a vpc or is a san port-channel restricted to ports on the same nexus switch only.
    Fabric A  fc1/31 & fc1/32    uplinked to  -> NX5K-1  Port fc1/31 & NX5K-2 Port fc1/32 (san port-channel 10 over a VPC)
    Fabric B  fc1/31 & fc1/32    uplinked to  -> NX5K-1  Port fc1/32 & NXFK-2 Port fc1/31 (san port-channel 11 over a VPC)
    Thanks,
    Ray.

    This is not possible. Vpc is layer 2 only ethernet port channel. San port channel cannot be built accross vpc

  • Does Solaris 10 support cisco Virtual Port Channels over IP?

    Does anyone know if Solaris 10 support cisco Virtual Port Channels open IP?

    Hi user11114413,
    The issue you are seeing actually has little to do with VIP, and more to do with there being multiple IP addresses for us to choose from on your box. For such multi-IP boxes, you'll want to tell us the IP to use, and in your case you want to tell as a VIP. This can be done either by editing your operational configuration file, and including an <address> element within the <unicast-listener> element, or via the tangosol.coherence.localhost system property. For example:
    <unicast-listener>
        <well-known-addresses>
            <socket-address id="1">
                <address>1.2.3.260</address> <!--virtual ip -->
                <port>8088</port>
            </socket-address>
        </well-known-addresses>
        <address>1.2.3.260</address> <!--virtual ip -->
        <port>8088</port>
    </unicast-listener>or
    java ... -Dtangosol.coherence.localhost=1.2.3.260If you are using the same operational configuration on all nodes in your cluster then the system property approach is likely preferable, and would only be necessary on the two machines sharing the VIP.
    As for using VIP or an extended WKA list, the choice is yours, either will work. If you do go the VIP route, it would obviously be a very bad idea to simultaneously use the same VIP and port at the same time from the two machines.
    thanks,

  • WLC Port Channel Host Flapping

    Hello,
    I have setup LAG for one of our 5508 controllers and have connected 4 of the 8 ethernet ports to a 4507 switch. After configuring 2 port channels on the switch we are receiving a host flapping error between the port channels and it seems to be causing a serious slowdown on the switch. When I shutdown one of the port channels the error goes away and traffic returns to normal. I have the same configuration at other locations with the only difference being the switches used are 3750G-12S and I do not see the host flapping error. It appears to only be a problem with modular switches.
    One other thing of note: I read a Cisco white paper on LAG and it suggested creating the port channels over 2 different modules. For example, put ports G4/24 and G5/24 in port channel 1 and G4/25 and G5/25 in port channel 2. I tried this but I still got the host flapping error.
    I searched the forum and found a few threads on the subject but no resolution. Any insight on a fix will be greatly appreciated.
    Thanks
    Mark

    Mark,
         Just to double check.  You configured two port channels on the switch, and connected these to the WLC?
    If that is the case, that is currently not a supported config.  You can split the ports across the modules, but you can't link two different etherchannels to the WLC.
    HTH,

  • MPLS-TE over Port-channel on 7206

    Hi Guys,
    I need an information: on a 7206vxr (ios 15.2S) I tried to configure an mpls-te over an etherchannel link but it doesn't seems to work (the TE tunnel never go up and the "show mpls traffic-eng tunnel tunnel 0 det" show the reason as "invalid path" but I guarantee that it's absolutely valid).
    I tried to search into feature navigator but I don't found any of that: It figure out as 7206 don't support it, it's right?
    Thanks in advance

    Hi Giulio, can you please confirm that to me?
      In the IOS feature navigator the feature "MPLS TE - Bundled interface support (EtherChannel and MLP)" seems to be available only in 7600 platform and not in 7200 series. And with 7200 series I have had some difficulty with MPLS TE in a port-channel interface.

  • Multiple vsan traffic over single port-channel

    Hi -
    Scenario - 2 interface uplink (port-channel - Po10 ) from NetApp FAS-A to N5548-A & B. Po10 is currently configured with vPC10 and vFC10 at N5k end. single vfc currently mapped with a single vsan (vfc10 with vsan 1011).
    Q - Is it possible to make the Port-channel to pass multiple vsan (vsan 1011 & 1012). If yes, then how (over same vfc or by separate vfc on same port-channel)
    Subhankar      

    This router’s capability is only limited and dependent on the services that your ISP has given or allowed for you to use. I think it really has to be a one is to one configuration, not only with this router because I haven’t noticed any router that has this feature so far. This is really another idea for Linksys can work on.

  • Pppoe over port-channels on ios xe

    has the ability to do pppoe and QinQ over port-channels been added to IOS XE? as of 2.6 it was not but I cannot find any documentation on 3.1-3.3 to say that it has or hasn't
    Does any one use a asr1000 as a BRAS and if so how do you handle redundancy in case of the loss of a primary interface handling your pppoe sessions?

    Does it matter what switch I start first?
    Thanks!

    Hi,
    Because you are using layer 2 interfaces - there is no fragmentation support at layer 2, and interfaces receiving frames which have an unsupported size will be dropped.
    I think the best way for you to proceed is to lab this up; and verify what happens - it may be that you need to make changes on switches at either end of the channel within a very short time frame to prevent too large an outage.
     When you are ready to maike your change - think the best way to do this is to use the interface range command, and apply the 'mtu' command to all the interfaces in this range. I don't think it matters which switch you apply this change to first, and I don't believe if you are hinting at the 802.3ad (controlled by system-priority) decision maker, that it makes any difference.

  • FCoE Port Channels on Single Nexus 5K - possible?

    I'm looking for information regarding FCoE on a single Nexus 5548. I'm trying to set up a port channel from a Netapp filer's CNA adapters (2 twinax cables). I was told that for some reason port channels do not work on a single Nexus 5K design (i.e. no vPC), but I didn't know if that meant simply without the use of LACP. I've configured it in both fashions, and it seems that the VFCs do not want to come up, meaning that my filers cannot log in to the SAN. This behavior is what was described to me as what would happen if I tried doing a port channel in this way - basically I've bound the VFCs to the port channels, and since the port channels are composed of ports on the same switch, it just doesn't work. Seems odd that this would bet the case, though it would normally force me to simply buy a second N5K (sneaky sneaky).
    Any tips?

    That's not my issue. I'm using only one Nexus 5K, meaning that if I want to have a port channel running between the 5K and the Netapp filers, I have to bind the virtual fibre channel interfaces to that port channel. I believe that in doing so, when there are more than one links as a member of that port channel, the VFCs simply go down by design and will not come up. For some reason VFCs require to be bound to a single physical interface, whether that interfaces is a single phyiscal port or a port channel that's only configured to have one port in it.
    Either way, I had to configure the Netapp side to be active/passive. I've bound the VFCs to each port (total of 4, so 4 VFCs as well). No port channels are being used on the Nexus side. This is not ideal but it works.
    I would still like to see some documentation regarding the behavior of the VFCs when presented with multiple links in this way. Has anyone seen any documentation regarding this?

  • 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 !

  • HSRP over L3 port-channel, switches do not ping each other

    Hello guys, 
    I have a L3 port-channel between 2 gigabit ethernet interfaces (one per switch Catalyst 6509), towards two giga interfaces in another two Catalyst 6509 in the other end. The port-channel is configured as follows in one of the ends (the first pair of 6509): 
    interface GigabitEthernet3/37
     description Conexion 
     no ip address
     channel-group 8 mode on
    interface GigabitEthernet3/38
     description Conexion 
     no ip address
     channel-group 8 mode on
    For each Catalyst 6509, the port-channel 8 has a HSRP group, 254. In one of the Catalyst (Central-1) the IP assigned is 192.168.254.253/24 and in the other (Central-2), 192.168.254.254/24. Here is the conf for one Catalyst 6509 (Central-1): 
    interface Port-channel8
     description CENTRALES
     ip address 192.168.254.253 255.255.255.0
     no ip redirects
     no ip unreachables
     no ip proxy-arp
     no ip route-cache
     load-interval 30
     standby delay minimum 20 reload 300
     standby preempt delay minimum 120
     standby 254 ip 192.168.254.254
     standby 254 timers 1 3
    As you can see, HSRP group 254 is defined and it is answering from L3, (from any host or switch, for the 3 IPs), but my doubt is about the HSRP behaviour between both Catalyst. They can't find which one is the master and in fact, they can't ping each other. The status of the group defined for po 8 is: 
    CENTRAL-1#sh standby port-channel 8
    Port-channel8 - Group 254
      Local state is Active, priority 100
      Hellotime 1 sec, holdtime 3 sec
      Next hello sent in 0.865
      Virtual IP address is 192.168.254.254 configured
      Active router is local
      Standby router is unknown
      Virtual mac address is 0000.0c07.acfe
      5 state changes, last state change 2w3d
      IP redundancy name is "hsrp-Po8-254" (default)
    CENTRAL-2#sh standby port-channel 8
    Port-channel8 - Group 254
      Local state is Active, priority 110
      Hellotime 1 sec, holdtime 3 sec
      Next hello sent in 0.645
      Virtual IP address is 192.168.254.254 configured
      Active router is local
      Standby router is unknown
      Virtual mac address is 0000.0c07.acfe
      5 state changes, last state change 6w1d
      IP redundancy name is "hsrp-Po8-254" (default)
    A "sh standby br" shows each switch considers itself the master and does not know the standby. 
    The thing is both switches have not an interface to connect L3 from network 192.168.254.0/24 directly. I mean, they only have one interface connected to the other end of the etherchannel, but not between them. Is this the reason why they can't ping each other, and consequently, they can't properly use HSRP group? 
    Could you tell me which could be a solution to this issue? I can't guess what can be done since the physical interfaces gi3/37 and gi3/38 exist and I think no any other interface should be configured in this network (192.168.254.0/24). 
    Thank you very much in advance. 

    Hello Jon, 
    Thank you very much for your answer. For the 3 possibilities, I answer you: 
    1) The pair are interconnected with a L2 trunk but the thing is this network, 192.168.254.0/24, is not associated to a vlan, but to a L3 etherchannel, so there is no way to associate it to a VLAN, am I right? 
    2) The other end of connections I think is configured at L3 too. 
    3) I am pending to know about the other end, but I think it is L3 too. 
    Anyway, although you have been very clear, try to imagine just 2 switches connected towards another 2 by one interface per each: 
    Central-1: gi3/37 ---> Ext1: gi1/20
    Central-2: gi3/38 ---> Ext2: gi1/30
    If etherchannel from Central is L3, I do not know how to include this traffic in vlan 2.... 
    Well, I keep on thinking. Thank you very much.
