Teaming or Port-channel support on NCS appliance

Hi, we have purchased one NCS PRIME-NCS-APL-K9 appliance. We are looking at connecting this box to two more swicthes configured in HSRP for the VLAN on which this box will be place. Can i configure active/stand-by teaming of both the ethernet ports available on this box.
If its possible, can you share with the relevant link on the Cisco website for the same.
Thanks in advance!

Have you gotten an answer to this question from any other source? Trying to find the same answer for a client.

Cisco Nexus 9300 Virtual Port Channel Support

Hi,
As I am new to Nexus 9300 and I was wondering if the switch may support virtual port channel (VPC)? I was wondering if there may be any feature matrix to compare it against the 9500/N7Ks/N5Ks
Any suggestion is appreciated.
Thanks.

Hi Marvin,
Appreciate for the information. I believe the customer is in the process of moving to ACI gradually however the setup I will be making will be classical ethernet setup which is similar to VSS setup whereby the N9300 would make use of VPC to connect to catalyst 3K/6K switch. I have illustrated it below for reference:
      Catalyst 6500 Non-VSS (Core)
      |----(VPC)---|
N9300 ----- N9300   (Aggregation/Distribution)
      |----(VPC)---|
Catalyst 3K switch (Access)
Appreciate for clarrifiying the support for VPC for Nexus 9300 as I made a search on feature navigator for "Virtual Port Channel" which only listed the N7K platforms.
Thanks.

Port channels across slots on a 6500

Hi experts,
we have 2 x 6509-E chassis NOT doing VSS, having a 10g module ( WS-X6708-10GE ) in each chassis. We plan to get another 10g module (same as existing) for each chassis. I was planning to move some ports from the existing module to the new module.
Question - Is a port channel supported across 2 modules on the same switch?
thnx

Hey,
Cross module etherchannel is supported as long as physical characteristics of ports match. Do check the QoS properties as well.
Also check the restrictions section as well:

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> 
            <port>8088</port>
        </socket-address>
    </well-known-addresses>
    <address>1.2.3.260</address> 
    <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,

"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.

Port channel failure / lacp_switch_get_new_agg_id: secondary l3 agg are not supported

hi,
hope that someone can help.
I ran into port channel issue when trying to add 4 port Quantum Dxi server into a port channel in 3750 stack.
Configs looks ok:
interface Port-channel6
description qdx-server
switchport access vlan 3
switchport mode access

end
all ports joined the channel except Gi 1/0/5 - it got suspended once joined the port channel

Port Channel Best Practice

Hi All,
I have a MDS9509 with port channels going to my Cisco blade switches on my HP Proliant blade enclosure.
I have NO ports left on my MDS9509, but DO have some remaining on the blade enclosure.
The question is, can i port channel from the blade enclosure to another edge switch (MDS9148)?
Is that a supported configuration/Best Practice and what are the ramifications if I do that?
So I'm going from Core, to edge and then to edge switch with port channel.
Thanks,
Matt

Hi Matthew,
Sorry for the misunderstanding, your to-be diagram cleared up a lot for me :-)
First off, yes, it will work. There's no reason it shouldn't and if you have the external ports free on your 9124e, you can hook up a new switch.
It's far from a conventional design, because blade switches are supposed to go in the Edge. It's not a best practice.
What I would recommend is that you move some of the storage from your edge to the 9148, and treat it as a collapsed core, sharing an edge switch (the blade switch). You can then ISL the 9148 and the 9509 together into a somewhat sensible topology.
So for one fabric this would be
(disk)---9148 --- 9509 -- (disks) (some moved to the left to free up space for ISLs)
9124e
Or you can contact your sales team and look to swap some Linecards with higher port density ones.
Lastly I would like to note that, however you link up the switches, most combinations available to you will 'work'. So as a temp solution you can go ahead with the (core - blade - edge) scenario. Just know that you'll be introducing bottlenecks and potential weak points into your network.

Create port channel between UCS-FI and MDS 9124 (F Mode)

Dear Team,
We were trying to create port channel between UCS FI and MDS 9124
But the port channel not getting active in F mode on MDS 9124
FI is in FC End Host Mode
We have enabled FC uplink trunking on FI
We have enabled NPIV on MDS
We have enabled trunk on MDS
FI and MDS in default VSAN
To check we changed the FI mode to FC Switching mode and port channels became active but in E mode
when we enabled FC uplink trunking on FI and FC Switching mode port channels became active in TE mode
but in both the above cases showflogi database shows WWPN of SAN alone not showing any from FI.
How to achive this?
Have read that no need to change the swicthing mode to FC Switching mode and keep as FC Endhost mode
SO how to achieve Port channel with F mode in MDS and FI ( Mode showing as NProxy)
Does it has to do anything with MDS NX-OS version? (https://supportforums.cisco.com/thread/2179129)
If yes how to upgrade as license for ports came along with Device and we do not have any PAC/PAK or license file as it came
with license
Also we have seen 2 files availabe for download (m9100-s2ek9-kickstart-mz.5.2.8b.bin and m9100-s2ek9-mz.5.2.8b.bin) which to use
Thanks and Regards
Jose

Hi Jo Bo,
what version of software if your MDS running?
On your UCS do connect nxos and show inteface brieft and look at the mac address.
it is possible that you might be hitting the bug below. if this is the case you might need to upgrade the firmware on your MDS.
Add MAC OUI "002a6a", "8c604f", "00defb" for 5k/UCS-FI

SG500x Port-channel limited bandwidth

Good Day All,
I have 2 Cisco SG500X-48 setup as Master/Slave using SFP-H10GB-CU1M (10GB Twinax cable).
First question is with the twinax cables
Since on the SG500x's you can not configure the 2*10GE Stacking Combo ports. If I put two cables in for redundancy will this cause a network loop, or will STP/RSTP catch this?
Next question is limited bandwidth.
I setup 4 Interfaces to Port channel with LACP. On the Server(HP Proliant Gen8 server(s)) end have the NIC Team with 4 NICs. When I run a network stress tool, it seems to cap at around 68MBs. Each port should being 1Gb, shouldn't I be getting closer to 4 GB?
My Configuration would read much like this:
VLANs setup:
##1-RF System
##2-VOIP
##3-LAN
interface Port-channel 3
spanning-tree portfast
switchport trunk allowed vlan add ##1,##2
switchport trunk native vlan ##3
interface gigabitethernet2/1/5
spanning-tree portfast
channel-group 3 mode auto
switchport mode access
interface gigabitethernet2/1/6
spanning-tree portfast
channel-group 3 mode auto
switchport mode access
interface gigabitethernet2/1/7
spanning-tree portfast
channel-group 3 mode auto
switchport mode access
interface gigabitethernet2/1/8
spanning-tree portfast
channel-group 3 mode auto
switchport mode access
I dont have much under standing on QOS yet, I assuming this would be based on setting up this?
Any direction or help would be greatly appreciated
Chris,

Hello Chris,
The way the stacking cables works is it detects when you are using two of them and switches over to what is called 'ring' mode. It doesn't use both links at once, but if one of those links fails it will immediately use the second one, usually not even dropping one packet. STP isn't an issue on the stack ports because it doesn't really use it, the stacking is a proprietary protocol that handles all of this for you. So go ahead and plug up your second set of cables, you should see a log message saying you have moved from 'chain' to 'ring'.
As for LAGs, this is a common misconception with link aggregation. I understand the logic, you have 4 gig links, why can't you get 4 gigs of throughput? It has to do with how LAGs actually work.
When a packet arrives at the switch and needs to go out the LAG the switch runs a calculation on the source and destination IP (or source and destiantion MAC depending on your settings). From this calculation it comes up with a number, in your case from 1-4. That determines the link that it uses to get across that LAG. There is no way to make one conversation use more than one link, it just isn't how it works. So when you run a speed test from one IP to one other IP, the result of the switch's calculation will always be the same number, hence all the traffic for that stream goes down the same link in the LAG.
There isn't any spillover, so even if one link is much busier then the rest it doesn't move them over to one of the other links.
On some enterprise switches you can use a load balancing algorithm that uses source and destination port, which can result in multiple conversations between the same two clients to use multiple links, but on the Small Business switches we only have IP or MAC.
Basically any one conversation will always be limited to whatever the speed of 1 link in the LAG is.
It is possible to utilize the link more, but you would need several different computers talking to the server to really see that. QoS would not change this.
As for your speed, it is a bit low, the max for a gigabit link is about 118MB/s (lab max, your mileage may vary) if you are using normal sized frames. This is assuming two devices directly connected to the with no routing required. How are you testing the speed? I like to use a program called Tamosoft throughput tester for this, which is available free on the web.
Hope that helps a bit,

Right way of configuring higher MTU over a Port Channel

Hi guys,
I have a running critical Port-Channel between two locations.
Here's the config
SW1:
interface Port-channel2
switchport
switchport trunk encapsulation dot1q
switchport mode trunk
end
interface GigabitEthernet1/45
switchport trunk encapsulation dot1q
switchport mode trunk
channel-protocol lacp
channel-group 2 mode active
end
interface GigabitEthernet1/46
switchport trunk encapsulation dot1q
switchport mode trunk
channel-protocol lacp
channel-group 2 mode active
end
SW2
interface GigabitEthernet1/1
switchport trunk encapsulation dot1q
switchport mode trunk
channel-protocol lacp
channel-group 2 mode passive
end
interface GigabitEthernet1/2
switchport trunk encapsulation dot1q
switchport mode trunk
channel-protocol lacp
channel-group 2 mode passive
end
interface Port-channel2
switchport
switchport trunk encapsulation dot1q
switchport mode trunk
end
Now I need to increase the MTU from default value to 9198. What the right way to do it and avoid any connectivity loss, PortChannel restart.
Does it matter what switch I start first?
Thanks!
L.E. both SW are WS-C4948

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.

Disappointed: ASA 8.4 Redundant using Port-channels

So I finally got all our ASAs upgrade to version 8.4 and was all sorts of excited to configure port-channels to our 6500 + SUP7203B switches. I was severally disappointed to discover that I cannot configure two port-channels and have them be members of a redundant interface pair. It would seem like a logical topology.
Port-channel1 = Gig0/0 & Gig0/1
Port-channel2 = Gig0/2 & Gig0/3
Redundant1 = Port-channel1 & Port-channel2
Port-channel1 would connect to the primary 6500
Port-channel2 would connect to the backup 6500
What would it take to make this work? Am I going to have to wait for 8.5? Will we finally get BGP then too? (Had to get that in there)
http://www.cisco.com/en/US/docs/security/asa/asa84/configuration/guide/interface_start.html#wp1329357
EtherChannel Guidelines
•You can configure up to 48 EtherChannels.
•Each channel group can have eight active interfaces. Note that you can assign up to 16 interfaces to a channel group. While only eight interfaces can be active, the remaining interfaces can act as standby links in case of interface failure.
•All interfaces in the channel group must be the same type and speed. The first interface added to the channel group determines the correct type and speed.
•The device to which you connect the ASA 5500 EtherChannel must also support 802.3ad EtherChannels; for example, you can connect to the Catalyst 6500 switch.
•All ASA configuration refers to the logical EtherChannel interface instead of the member physical interfaces.
•You cannot use a redundant interface as part of an EtherChannel, nor can you use an EtherChannel as part of a redundant interface. You cannot use the same physical interfaces in a redundant interface and an EtherChannel interface. You can, however, configure both types on the ASA if they do not use the same physical interfaces.

Hello Yaplej,
Agree with you but unfortunetly this is not supported yet,
We migh need to wait some time before this desing can be accomplish,

Nexus 7010 port-channel to ESXi host running on Dell 910 and 810

Was wondering has anyone had any experience with configuring a port-channel going back to ESXi host. My basic config is below. My issue is with what to put in the spanning-tree port type. Do I use normal, edge, network, or edge trunk?? Yes I have read most of the documentation out there but am just a lil confused. I just wanna be right.
Also if anyone has any suggestions for the Vswitch config as well that would be much appreciated.
int PO 201
desc 01_6-1
switchport mode trunk
switchport access vlan 99
switchport trunk native vlan 777
switchport trunk allowed vlan 220,300,310,320-321,350,390-391
switchport trunk allowed vlan add 420,777
spanning-tree port type normal (what should go here)
speed auto
medium p2p
no shutdown
int e8/11
desc 01_6-1
channel-group 201 force
int e10/11
desc 01_6-1
channel-group 201 force
Thanks Guys

Short answer: You could use spanning tree port type edge (trunk; if it's going to be a trunk). The vswitch isn't really a switch, it doesn't participate in spanning tree, so it's fine to make it an edge port.
In my experience, many VMware guys don't like port channels as much as the other more host-centric NIC teaming methods. I think this has to do with ESX having a less than stellar implementation of etherchannel/LACP early on.

Sg300-28 port-channel options

i have an sg300-28 running the latest firmware, and would like some insight on port-channel options. below are the port configs i have for a LAG to my router. i am currently using 802.3ad with LACP. my router is a linux machine pulling duty as a basic (no dynamic routing) router, firewall and internet gateway. the bonding options on the routers side explained at
http://docs.fedoraproject.org/en-US/Fedora/16/html/System_Administrators_Guide/sec-Using_Channel_Bonding.html. the mode is 4 or 802.3ad and the xmit_hash_policy is 2 or layer2+3. i also have 2 servers setup in a similar fashion with 2 interfaces in a LAG.
when i run a bandwidth test, iperf, between the two servers, i only get 900+ mbps which indicates that the GB ports are running fine. this also indicates to me that the traffic is not being "striped" across the port-channeled interfaces, thereby giving me the aggregated bandwidth of all interfaces in the LAG. i have found no options to use the balance-xor mode to create port-channels, which as i understand it, would aggregate the total bandwidth of all interfaces in the LAG. is the sg300 capable of creating a LAG that will combine the throughput of all the members of the LAG? for example, create a 2 GB pipe when 2 interfaces are port-channeled? is the balance-xor mode what would do this (regardless of the sg300's ability to do this)

Hi Brendan,
You said "i only get 900+ mbps which indicates that the GB ports are running fine. this also indicates to me that the traffic is not being "striped" across the port-channeled interfaces, thereby giving me the aggregated bandwidth of all interfaces in the LAG. i have found no options to use the balance-xor mode to create port-channels, which as i understand it, would aggregate the total bandwidth of all interfaces in the LAG."
As the Admin guide says on page 130, http://www.cisco.com/en/US/docs/switches/lan/csbms/sf30x_sg30x/administration_guide/78-19308-01.pdf
Load Balancing
Traffic forwarded to a LAG is load-balanced across the active member ports, thus achieving an effective bandwidth close to the aggregate bandwidth of all the active member ports of the LAG.
Traffic load balancing over the active member ports of a LAG is managed by a hash-based distribution function that distributes Unicast and Multicast traffic based on Layer 2 or Layer 3 packet header information.
The switch supports two modes of load balancing:
By MAC Addresses—Based on the destination and source MAC addresses of all packets.
By IP and MAC Addresses—Based on the destination and source IP addresses for IP packets, and destination and source MAC addresses for
non-IP packets.
   So, an IP host running running IPERF maybe checking unicast throughput between the two IP hosts. There will be a Source and Desination IP address in that test. The switch will direct the traffic over one of the LAG port members . It wont Round robin the unicast traffic over multiple LAG ports, if the Source and Desination IP address of the traffic is the same. .
If the PC running IPerf, had another concurrent IPerf session to another or different IP host, the hash algorithm on the switch may direct that stream , maybe, over a different physical LAG interface.
So your comment about achieving 900+mbps sounds normal   Yes LAG spreads the load, the benefit comes when lots of hosts on both sides of the switches.
You hay find with just two hosts on either side of a LAG, that the switch may run the traffic between two hosts over just one member of the LAG group.

Port Channels - WLC 5508 and 4510

LACP and PAgP are not supported on the controller and it appears that the 4500 series will not use LAG.

I am getting the error, "lacp not enabled on remote port..". I removed the 2nd fiber cable and removed the channel-group so I could get the WLC back online. Any help would be greatly appreciated.

In order to get the ether channel to work with the WLC you need to change your configuration from:
interface GigabitEthernet3/1
channel-group 10 mode active
interface GigabitEthernet3/2
channel-group 10 mode active
To mode ON
interface GigabitEthernet3/1
channel-group 10 mode on
interface GigabitEthernet3/2
channel-group 10 mode on
Mode ON tells the switch to do Link Aggregation Protocol and does try and negotiate using one of the two control protocols LACP or PAgP.
using mode ON is part of the configuration guide when enabling Cisco WLC LAG option.

So I have the following questions about verion 9:
1. Can I still use port-channels on a sigle ASA?
2. Should I replace port-channel by lacp command on a sigle ASA?
3. Does lacp command can be used only on clusters ?

The following is documented in the config guide for both 8.4 and 9.0:
•You cannot use interfaces on the 4GE SSM, including the integrated 4GE SSM in slot 1 on the ASA 5550, as part of an EtherChannel.
So, even with 8.4 it was probably never meant to work.
