F-port-channel-trunk disruptive or not?
Hi,
We have a N5K with NPIV configured and and MDS9148 we're gonna setup a port channel and have come to the conclusion that we need the F-port-channel-trunk feature enabled on the MDS side.
Question: Is enabling the F-port-channel-trunk feature on the MDS disruptive or non-disruptive?
--M
It's too late; I would say it is disruptive; however, the disruption is so short, that you didn't notice it. Similar without non F-port trunking channeling: using a link: the lost sessions are simply redistributed over the remaining links; new flogi is necessary.

Fabric Interconnect To MDS 9148 FC Port Channel/Trunks
Is it possible to create both a Port Channel and Trunk on a Cisco MDS 9148? Yes correct?
Or can I only trunk between the 2 MDS switches and not the MDS to Fabric Interconnect?
These FC links would be connected to a 2248XP Fabric Interconnect carrying multiple VSANs from the MDS to the Fabric Interconnect.
ThanksHello,
Yes, you can have trunk links grouped into port channel ( F port-channel trunking ) between FI and MDS.

Hi, Cisco Experts:
Can I have a definitive answer to the following?
q1.
EMC mentioned that they do not support FC Port Channel & Trunking with regard to our UCS Fabric Interconnects/MDS/VNX5300?
Is that any truth in that?
We are trying a Cisco UCS solutions with MDS and EMC VNX in the mix-SAN Boot basically, ESXi 5.1 and all others.
q2.
From MDS all the ways up to EMC VNX, is there such concept too-FC Port Channel & Trunking, assuming we are doing FC Port Channel & Trunking from FInterconnect to MDS?
Please let me know.
Appreciate it.
SiMHi Sim,
We support FC port channel and trunking between UCS FI and MDS.
Is EMC saying about the port channel between the MDS and VNX? Is there any document EMC pointed out?
With respect to booting from SAN, yes, you can boot from SAN with MDS and EMC VNX as long as the OS is supported in the UCS system. You can refer to
http://www.cisco.com/en/US/products/ps10477/prod_technical_reference_list.html for the supported OS versions.
Hope this answers your question.

MDS Code Level for UCS FC Port Channel/Trunking
What is the required MDS code level needed to support FC Port-Channeling/Trunking on a 9222i, 9148, or 9509/9513 w/ Gen2 line cards to UCS 1.4(3)?
I know the fport-channel-trunk feature is needed and was released in MDS 4.2 code but I have seen documents that this level of code wont support these features when used to connect to Cisco UCS.
Can someone confirm? Is NXOS 5.0(4) or higher required?Doug,
I wrote the doc almost a year ago and it doesn't have the latest interop matrix support information. The current MDS NX-OS support is located in this doc: http://www.cisco.com/en/US/docs/switches/datacenter/mds9000/interoperability/matrix/intmatrx.html
While, I wish this was also duplicated in UCS docs, they are more or less taking the stance that 3rd party (Cisco MDS is this case) interop is maintained by the 3rd party. EMC, Netapp, or even Cisco.
It would be a nightmare updating UCS docs with 3rd party qualifications and support.
The short answer to your question is:
UCS 1.4(1), 1.4(2), 1.4(3) Is supported by MDS9000: 3.3(4a), 3.3(5), 4.2(1a), 4.2(1b), 4.2(3a), 4.2(5), 5.0(1a), 5.0(4), 5.0(4c)
NPV was introduced in MDS 3.3. f port-channel/trunk was introduced in MDS 4.2.
As Ram mentioned above, 4.2(5) is what I would recommend if I wanted to implement f port-channel and/or f port-trunk. I have also had recent experience with 4.2(5) and it worked great with a large UCS f port-channel/trunk implementation
The specific switch limitations I mentioned in my doc still exist. Only certain models of MDS will support f port-trunk. Almost all models will support f port-channel.

Thank you for your answer. I did everything but it did not work. Turn out it is a bug ver 8.45 will let you created the sub logical interface but actually it did not work right. Verson 9.x doesn't let you create more than 2 port channel (limitation of ASA5550 hardware).

Port-channel / Trunking / VSAN
Hi all,
I have a quick question...
I enabled trunking for all vsans and created a port-channel. I want to use this port-channel for all my vsans.
Does it matter in which vsan I add my port-channel?
If it doesn't matter why can I assign a port-channel to a vsan?
Cheers,
MikeMike,
It should be the same configuration on both sides for the port-channel to come up. The reason why you can assign a port-channel to a VSAN is that if you are using an E port then it depends on the matching port-channel VSAN to come up.
TE Port functionality is specific to MDS for enhanced ISL capabilities. E ports can be used for non-cisco switches to make the trunk work seamlessly as an E port.
You can refer to the following for more info:

SGE2010 port-channel and trunking config question
I have port-channels configured and working for the native VLAN on multiple SGE2010s. I now want to add multiple VLANs and enable trunking for the port-channel. I am not clear on the appropriate way to enable trunking as it can be enabled on the port and on the port-channel. The ports and port-channel are currently in access mode. If anyone can provide the correct configuration, I would appreciate the guidance. I also need to get the port-channels and trunking working with 3Com 4500 & 4200s. If you know of any configuration issues, again any guidance would be appreciated
Hi Jacqueline,
Sorry Juans answer needs some correction, but I am grateful for Juans participation.
The SGE2010 does not support a CLI.
There is a unsupported CLI, that someone plastered somehwere on this community, but i must admit i still like to use the GUI.
The software on the SGE2XXX was recently updated so you can find that on the cisco.com website.
I have created a link below to a recording i just made, regarding Link aggregation on the SGE2XXXX, i thnk if you see the 11 minute recording a couple of times, maybe pause it, play with your switch, it will start to make sense.
you can't breat the switch by configuring it

FC Port Channel between UCS and MDS.
Hi All,
I am new to Cisco Fabric Concepts. In my enviornment i have a F port channel(8 Port Group) created on MDS 9513 switch and this Fport
channel is connected to Cisco UCS 6296 FI. The Cisco UCS Blade servers are connected to the Fabric Interconnect .
On MDS NPIV is enabled.
Can anyone explain the below questions.
1. Why do we create an F port Channel Group and connect it to the UCS FI? Is this something similar to Brocade Edge to AG Switch Connectivity.
2. How to configure F port Channel Group in MDS . Can anyone explain with an example.
3. Do we need to make any Configuration on UCS FI ports for server connectivity and Channel port Connectivity if yes what are the steps required to
do the same.Does the WWPN shows up in the FLOGI Database if the connectivity and configuration looks good in UCS FI and MDS.
4. What happens when a VSAN on MDS switch is added to the Port Channel.
Thanks and Regards,

F port channel is proprietary; therefore any such F port channel between UCS FI and Brocade doesn't work.

flogi database is on the MDS, not FI; there are however UCS CLI commands, like "show npv ...."

Hello,
Once in production, when adding cables in a Fabric PortChannel between an IOM and a FI, ¿is it needed to re-ack the chassis? (so that, we'll have downtime of the whole chassis). Or rather, as it is a Port-Channel the cables are detected automatically, so that it is not needed to re-ack, and so there's no downtime at all...which one is the correct statement?
Thanks,Hello,
Let us consider following scenario on adding or removing links to existing deployment.
Initial deployment
UCSM 2.0, FI 62XX ,2208 IOM and 2 physical links with port channel configuration ( 2 link discovery policy )
Change
1) If additional links are added and if they need to be utilized and part of port channel, we need to re-ack the chassis.
2) If a link goes down,traffic is distributed across other links in port channel and does not require re-ack. Parameters like bandwidth, VIF ports that are calculated based on initial configuration remains the same.
3) If we physically remove the additional links between IOM / FI, re-acknowledment would create port-channel with original two links.Failure to re-ack will create over subscription ( bandwidth, available VIF ports ) of the network links.Re-ack is not mandatory but it creates appropriate configuration that matches required design criteria.
Caution
Adding or removing links from a fabric port channel is disruptive and may affect the available amount of VIF namespace.

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 ;-) )

Hello,
We have two Catalyst 4006 as core switchs in our network. Other access layer and server layer switchs (also Catalyst 4006) connect to the two core switchs; two Gigabit Ethernet links between one layer switch and one core switch form a port channel.
Now I add one Catalyst 4507 switch in the backbone, Il connects to each core switch by two GE links formed a port channel. The show spanning-tree command presente different port-channel type for the older(P2P Peer STP and the new port-channel (PO31, only P2P, not peer STP).

Jessie DongHi Jessie,
You are running RSTP, which sends version 2 BPDUs. If the switch receives on a port version 0 BPDU (i.e. regular STP BPDUs), it will go to an STP compatibility mode and will start sending version 0 BPDUs on this port.
So basically, what you are seeing is that all your neighbors are running STP, except the one connected to Po31 who is running RSTP.

How to configure a port channel with VLAN trunking (and make it work..)
We're trying to configure a port channel group with trunked ports to connect a NetApp HA pair. We want to create two data LIFs and connect them to the switch stack. We are trying to create 2 data lifs, one for cifs and one for nfs that are on different vlans.
We want the same ports to be able to allow multiple vlans to communicate. (trunked)
These data lifs should be able to fail over to different nodes in the HA pair and still be able to communicate on the network.
What this means is that we have to connect 4 ports each for each node in the NetApp HA Pair to the switches and create a port channel of some type that allows for trunked vlans. When we configure the ports, the configuration is as follows (below):
We are only able to configure an IP on one of the vlans.
When we configure an IP from another vlan for the data lif, it does not respond to a ping.
Does anyone have any idea what I'm doing wrong on the Cisco switch?

Difference between Trunk links and port channel

As the other posters have already described, in Cisco parlance, a "trunk" is a link that carries VLAN tagged frames. (Note, Cisco has two technologies for these, ISL [old/proprietary] and IEEE 802.1Q [vendor independent].) An Etherchannel (also called a port-channel) is one logical link that includes one or more physical links. (Note, although Etherchannel can run across just one link, normally more than one link is configured. Older and most Cisco implementations support up to 8 links in one channel bundle. There's also multiple Cisco technologies that support Etherchannels, such as manual/PAgP[Cisco/old]/LACP[IEEE 802.3ad].)
Trunk links might also be configured on an Etherchannel link. -
Do I configure spanning-tree port type ed trunk on LACP port-channels
Hello,
Can't seem to see a clear answer and wondering if something could offer some advice please?
We are using LACP aggregation across all our 10 gig attached servers and also trunking them. We're running a VPC pair of 5596 Nexus.
For a standard trunk port I always add the spanning-tree port type edge trunk to the interface config.
However I think I should be adding this to the overiding port-channel config. At present a colleague has configured the VPC below omitting the spanning-tree port type config.
interface port-channel100
description a-server
switchport mode trunk
switchport trunk allowed vlan 100
vpc 100
The port member configs are these which do contain the spanning tree port type:
interface Ethernet1/1
description a-server(1)
switchport mode trunk
switchport trunk allowed vlan 100
spanning-tree port type edge trunk
channel-group 100 mode active
I always try to keep the overiding port channel config the same as its members and obviously for most config, you can't have disparate configs anyway.
However for the spanning tree config the NexOS allows you to have the members with spanning tree port types and not have to reflect that in the port-channel.
However I have this issue with STP:
Switch1# show spanning-tree interface po100
Vlan Role Sts Cost Prio.Nbr Type
VLAN0100 Desg BKN*200 128.4996 (vPC) Network P2p *BA_Inc
Is this due to the inconsistency with my port channel to member configs?
Any advice would be gratefully accepted.
Thanks!Hi Paul, there are some parameters you can define on individual ports and there are some of them that will be inherited from the port-channel configuration no matter what has been configured under the infidividual ports. Spanning-tree configuration is one of the inherited ones. As soon as the port joins into a port-channel, it will start to use spanning-tree settings under the port-channel. When it leaves the channel, then it can continue to use the individual configuration.
There is a nice summary here under NX-OS Interface Conf Guide > Port-Channel Conf:

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

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).

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.
