Interface Port Channel
My port channel is not coming up can you review my port channel configuration.

Hello,
how are your participating interfaces configured ? They should look like this (assuming you use interfaces FastEthernet0/1 and FastEthernet0/2 for your channel on both devices):
3550-1#
interface FastEthernet0/1
switchport access vlan 513
switchport mode access
channel-group 12 mode on
interface FastEthernet0/2
switchport access vlan 513
switchport mode access
channel-group 12 mode on
interface Port-channel12
switchport access vlan 513
switchport mode access
3550-2#
interface FastEthernet0/1
switchport access vlan 513
switchport mode access
channel-group 12 mode on
interface FastEthernet0/2
switchport access vlan 513
switchport mode access
channel-group 12 mode on
interface Port-channel12
switchport access vlan 513
switchport mode access
Do you have physical connectivity at all ?
Regards,
GP

Interface port-channel btw N2K and Brocade VDX
Dear all,
I tried to configure a port-channel between a nexus 2K (2FEX) and a brocade VDX (VDX6710).
As you seen below, my configuration :
N2K
Po10
switchport access vlan 200
Eth101/1/6
switchport access vlan 200
channel-group 10 mode active (used LACP)
Eth102/1/6
switchport access vlan 200
channel-group 10 mode active (used LACP)
VDX
interface Port-channel 27
vlag ignore-split
speed 1000
switchport
switchport mode access
switchport access vlan 200
spanning-tree shutdown
no shutdown
interface GigabitEthernet 21/0/31
channel-group 27 mode active type standard
lacp timeout long
no shutdown
interface GigabitEthernet 22/0/31
channel-group 27 mode active type standard
lacp timeout long
no shutdown
Unfortunately, we can't up the link for interfaces and so the port-channel.
We have the next message from the N5K for FEX :
%ETHPORT-5-IF_ADMIN_UP: Interface Ethernet101/1/6 is admin up .
%ETHPORT-5-SPEED: Interface Ethernet101/1/6, operational speed changed to 1 Gbps

%ETHPORT-5-IF_DOWN_ERROR_DISABLED: Interface Ethernet101/1/6 is down (Error disabled. Reason:BPDUGuard)
Any idea about the configuration ?
Thanks for your help.
MatthieuFexes are really made to connect hosts and not switches . So the ports should not see bpdu's so bpduguard is err-disabling the ports.
Spanning Tree Protocol
HIFs go down with the BPDUGuard errDisable message
HIFs go down accompanied with the message, BPDUGuard errDisable.
Possible Cause
By default, the HIFs are in STP edge mode with the BPDU guard enabled. This means that the HIFs are supposed to be connected to hosts or non-switching devices. If they are connected to a non-host device/switch that is sending BPDUs, the HIFs become error-disabled upon receiving a BPDU.
Solution
Enable the BPDU filter on the HIF and on the peer connecting device. With the filter enabled, the HIFs do not send or receive any BPDUs. Use the following commands to confirm the details of the STP port state for the port: -
Nexus 1010v interfaces, port-channel, Catalyst 6500E VSS
I'm installing a pair of 1010v-X appliances using flexible network option 5 on version 4.2(1)SP1(5.1).
I have all interfaces grouped into a single port channel 6. All interfaces uplink to a pair of Catalyst 6506Es in a VSS (Sup2T).
My question relates to the VSS configuration.
For example, do I set up one port-channel on the VSS and put all 12 interfaces in it? Or, do I set up two port-channels on the VSS and put the active 1010v-X in one port-channel and the standby into another port-channel?
Do I set dot1q trunking up on the port-channel(s) on the VSS?
Thanks.Hi,
What version of IOS are you running on the ASAs?
see table-12-3 in this link:
http://www.cisco.com/c/en/us/td/docs/security/asa/asa84/configuration/guide/asa_84_cli_config/interface_start.html
Also, since the 4500x are in VSS mode, you need to bundle one link from each switch and use LACP.

UK-LON-FW(config-if)#Hi Marvin,
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).
https://tools.cisco.com/bugsearch/bug/CSCtq62715/?reffering_site=dumpcr
Also, you can see the 8.4 release notes were you can see that it is not supported:

EtherChannel support (ASA 5510 and higher)
You can configure up to 48 802.3ad EtherChannels of eight active interfaces each.
Note 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.
We introduced the following commands: channel-group , lacp port-priority , interface port-channel , lacp max-bundle , port-channel min-bundle , port-channel load-balance , lacp system-priority , clear lacp counters , show lacp , show port-channel . -
Policy maps on port-channel sub-interfaces
We're trying to implement an enterprise QoS policy and I'm wondering how we can apply our QoS policy maps to several different sub-interfaces on a port-channel. In our case, we have both LAN and WAN connections that connect as VLANs on a switch and terminate as sub-interfaces on a port-channel that combines two Gigabit Ethernet interfaces on our router. The LAN connection will need to have a ingress service-policy to classify traffic as it comes from a customer LAN, and the WAN connections will have to have an egress service-policy to place the traffic classes into LLQ and CBWFQ queues as it leaves the router. Could I put both the ingress and egress service-policies on the physical router interface, or should I put them on the port-channel interface? Or should I apply them to the individual sub-interfaces? For example, I could put the ingress classification service-policy on the LAN sub-interface connection.
Any thoughts or insight would be helpful. Thanks.I can't put it as input because :
gw-a(config-subif)#service-policy input policy_upload
Traffic Shaping feature not supported in input policy.
Here's a show during a bandwidth test. You can see the offered rate is properly measured and is _way_ above the target shape rate.

hey I have a question about port-channel.
we have a port-channel 10 which contains 4 interfaces as below.
my question is how the port-channel associated with the servers? I mean the output "sh flogi database" as below........
do we need to add port-channel as a zone member ? I think the answer is no since I don;t see the port-channel as a zone member....

Design help related to ACE to Switch connectivity using Port-Channel
Hi,
I have a Cisco ACE 4710 configured in One-Arm mode. This ACE is getting connected with 2 3750 switches. These 2 3750 switches connected in trunk mode.
ACE is connected to these 3750 switches using Port-channel.

===========================================================
The problem is that 3750 switches are not stacked.
Application is working fine. But i am getting a lot of MAC flapping messages..
kindly suggest whether this design is OK or something needs to be done to rectify it...
Attached a small diagram..Hello acharyr123,
I don't think this design is ok, and it would cause mac flapping since the two indepedendent 3750 switches will learn the ace mac addresses off of two different interfaces. The 3750s would have to be stacked so that they would act as one switch then this should work correctly.
Thanks

Can you share us the status about interfaces 1/5 - 6 & 3/45, 4/45 of 7k?
Do you have configured per Ethernet interfaces or on the Po ? -
ACE - Port-channel High Availability
We have configured two ACEs with high Availability. ACEs link with our cores, switches cat6500, through a port-channel, ACE’s ports G1/1 and G1/2. High availability works fine if some vlan down but it doesn’t work if an interface down, only if both interfaces get down because then, all vlans of the channel port get down two.
If possible get an interface port-channel high availability?
Thanks for your help in advance.Thanks for your answer. I have two Cat6500, no VSS possibility. I have two ACEs so each one has configured a port-channel with one Cat6500 (two ports). It works fine. Any problem with that. My issue is when one port-channel of both port is down, failover doesn’t works then, only if both ports are down or vlans are down. I think high availability is only possible in vlan interfaces, not in physical interfaces.

Nexus 6K: Port-Channel Load-Balance
Hi all,
I configured "port-channel load-balance ethernet source-dest-mac" on Nexus 6001. But when I use "show run all | in load-balance", it displays module 1 and module 2 are still using source-dest-ip for port-channel load-balance. And for command "show port-channel load-balance" and "show port-channel load-balance forwarding-path interface", it still shows switch using MAC for hash algorithm. The NXOS is 6.0(2)N1(2a).
Does anybody know:
- What is the function of "port-channel load-balance ethernet source-dest-ip module" and in which situation this command will be effective?
- It shows "port-channel load-balance ethernet source-dest-ip module" command for both module 1 and 2. Module 1 is N6K Supervisor and module 2 is 4xQSFP Ethernet Module. Is it possible to set different load-balance algorithm to these 2 modules?

Configuring 9222i for Port-Channels to 6500

Hi
I was trying to configure two 6800x switches as a VSS pair, Ive done this on 4500x switches before and worked a treat. when setting up a L2 port-channel, for some reason it puts the ports into routed mode and does not allow me to build a L2 port-channel.
So I add the following config for the port-channel
Interface port-channel 10
Description VSL_Link
switchport
switch virtual link 2
no shut
Interface range Tengig 1/1 – 1/2
Description VSL_Link
switchport mode trunk
channel-group 10 mode on
Now as soon as I type the channel-group 10 mode on, it gives an error
"Command rejected (Port-channel10): Either port is L2 and port-channel is L3, or vice-versa"
I managed to create a L2 port-channel on a 4500x, will the 6800x only allow me to create a l3 port channel.Hi
I tried this config on the 4500x and it worked, now I have also added the switchport mode trunk command to both the port-channel and interface and still getting the same error.
When I do sh int status, the ports are showing as routed
I cleared the config and first set both interface as trunks, then when I do the channel-group 10 mode on command, it accepts the command an automatically creates the port-channel, but the interfaces show as routed.
This is my first time using a 6880x, when i logged into it, the default hostname is set to Router. I was expecting it to be named Switch, not that the hostname affects the config but makes me wonder, is the config different for the 6880x as opposed to other L3 switches -
Port-channel Problem between Fabric Interconnect and N7K vPC
Dear all,
I have a problem with Port-channel Uplink between Fabric Interconnect with N7K using vPC
This is my network topology for UCS Deployment
In N7K I has configured vPC for red link and green link, at Fabric Interconnect A I has configured Port-Channel with member is Port 1 and Port 2, uplink is red link. At Fabric Interconnect B, I has configured Port-Channel with member is Port 1 and Port 2, uplink is green link.
The show interface port-channel on N7K is good, every port-channel is up and have all member. But At Fabric Interconnnect, when I see on UCS Manager, the status of Port-Channel on Fabic A and Fabric B is fault with Additional Info: No operational member. Although all link is link up and I has status of Port-Channel is enable on UCS Manager. When I see the Properties of Port 1, Port 2 on Port-channel, I see the membership status is : individual. This mean port-channel is not up and no membership in this configuration. I want to using port-channel for load balance and plus more bandwidth for uplink to 20Gig. I don't understand why ?
Please help me resolve this problem, I has send the capture screen of UCS Manager when I show status of Port-channel and Port-member in port-channel in attach items.
Anyone can help me to resolve this, thanks you very much. Please reference attach items for more detail about fault.
Thanks,
Trung.Thanks Matthew very much,
I has resolved this problem. The reason of problem is miss match protocol of port-channel between N7K and Fabric Interconnect. The Fabric Interconnect always use LACP protocol, but N7K using Port-channel mode on, that why the port-channel failed. I has configured LACP for port-channel in N7K, it has resolved the problems.
Thanks,
Trung. -
Catalyst 3750G and WLC 440x - Port Channel - Configuration - Best Pactice
What is the best practice to use when configuring port channel between Catalystr 3750G switch stack and WLC 4402 / 4404 Wireless Lan Controllers:
a) Negotiate to LACP
b) Negotiate to PAgP
or
c) Hard-code to Port Channel without any negotiation.
Any pointers to any useful links - much appreciated and configuration example as well.Answer is 'C'... channel-mode on
Configuring Neighbor Devices to Support LAG
The controller's neighbor devices must also be properly configured to support LAG.
â¢Each neighbor port to which the controller is connected should be configured as follows:
interface GigabitEthernet
switchport
channel-group mode on
no shutdown
â¢The port channel on the neighbor switch should be configured as follows:
interface port-channel
switchport
switchport trunk encapsulation dot1q
switchport trunk native vlan
switchport trunk allowed vlan
switchport mode trunk
no shutdown
Here is a link that explains it. Hope this answers your question:

MDS configuration for port channel
I've tried to set up the new FC port channel upload to a pair of MDS 9124s, but as I don't know enough about the MDS side I can't get the link to come up. Are there any references available anywhere that tell you blow by blow exactly how to configure the MDS side of the port channel? Or perhaps a sample working config?
ThanksSimon,
A few items:
1) You are on 1.4.1i Balboa code
2) FI's are in FC switch mode as MDS 9124's don't support F-port channel (NPV/NPIV)
3) It's a lot easier the first time if you have matched speed sfp+ all around. Although, with the correct configs, unmatched speeds can be made to work.
If the FIs are in switch mode and your MDS is running a minimum 3.3 here are some configs that may help:
MDS side interfaces 4/11 and 4/12 are plugged into the UCS fc ports. First setup and ensure ISLs are working properly between UCS and MDS, then configure the port-channels
interface fc4/11
switchport rate-mode dedicated
switchport mode E
switchport trunk mode auto
no shutdown
interface fc4/12
switchport rate-mode dedicated
switchport mode E
switchport trunk mode auto
no shutdown
The UCS GUI Equipment -> Fabric Interconnects -> FI-A -> Set FC Switching Mode. This will cause both FI's to reboot into FC switch mode. This is VERY DISRUPTIVE, both FI's will reboot.
On the UCS CLI you should see this on the UCS fc ports connected to the MDS
cae-sj-ca3-A(nxos)# show running-config interface fc 2/1-2
!Command: show running-config interface fc2/1-2
!Time: Wed Oct 20 16:49:39 2010
version 4.2(1)N1(1.4)
interface fc2/1
switchport mode E
no shutdown
interface fc2/2
switchport mode E
no shutdown
Until you have VSAN trunks enabled, make sure the ports on the UCS and MDS are in the same VSAN. VSAN 1 for example.
Once you have working ISLs, then proceed to turn them into port-channels and enable VSAN trunking. Start with the MDS
Create a channel group, it should look like this
cae-sj-9506-1# show run interface port-channel 3
!Command: show running-config interface port-channel 3
!Time: Wed Oct 20 17:06:01 2010
version 5.0(1a)
interface port-channel 3
channel mode active
switchport mode E
switchport rate-mode dedicated
switchport trunk mode auto <-- VSAN trunking
Enable VSAN trunking on the MDS ISL interfaces, it'll look like this:
cae-sj-9506-1# show run interface fc 4/11-12
!Command: show running-config interface fc4/11-12
!Time: Wed Oct 20 17:07:05 2010
version 5.0(1a)
interface fc4/11
switchport rate-mode dedicated
switchport mode E
switchport trunk mode auto
no shutdown
interface fc4/12
switchport rate-mode dedicated
switchport mode E
switchport trunk mode auto
no shutdown
Add the channel group information to the MDS ISL interfaces:
Enter configuration commands, one per line. End with CNTL/Z.
cae-sj-9506-1(config)# interface fc 4/11-12
cae-sj-9506-1(config-if)# channel-group 3 force
fc4/11 fc4/12 added to port-channel 3 and disabled
please do the same operation on the switch at the other end of the port-channel,
then do "no shutdown" at both ends to bring it up
cae-sj-9506-1(config-if)# show run interface fc 4/11-12
!Command: show running-config interface fc4/11-12
!Time: Wed Oct 20 17:07:39 2010
version 5.0(1a)
interface fc4/11
switchport rate-mode dedicated
switchport mode E
switchport trunk mode auto
channel-group 3 force
no shutdown
interface fc4/12
switchport rate-mode dedicated
switchport mode E
switchport trunk mode auto
channel-group 3 force
no shutdown
Create the SAN port channel on the UCS side
SAN -> SAN Cloud -> Fabric A -> FC Port Channels -> Create Port Channel
After you create the SAN port channel in UCS, make sure and enable it. I also bounce the MDS port channel at this point.
If all is correct, in a few agonizing minutes, the port-channel will be formed and passing data.
cae-sj-ca3-A(nxos)# show interface san-port-channel 1
san-port-channel 1 is trunking
Hardware is Fibre Channel
Port WWN is 24:01:00:0d:ec:d3:5d:c0
Admin port mode is E, trunk mode is on
snmp link state traps are enabled
Port mode is TE
Port vsan is 1
Speed is 8 Gbps
Trunk vsans (admin allowed and active) (1,10,26,50,66,100-101,103,123,222,24

Trunk vsans (up) (1,10,50,100,103)
Trunk vsans (isolated) (26,66,101,123,222,240)
Trunk vsans (initializing) ()
5 minute input rate 2312 bits/sec, 289 bytes/sec, 2 frames/sec

Again, make sure you have the ISLs up an running first before configuring the port-channels. It makes troubleshooting much easier.
