Channel-group mode for VSS MEC link to WLC

Hello
I have a Cisco 5508 WLC with LAG enabled - this LAG connects to a single VSS chassis (VSS etherchannel mode is "on" as per the WLC documentation)
I'm looking to spread this LAG across both the VSS chassis - Cisco's VSS best practice document below states that for Multi Chassis Etherchannel "Do not use on and off options with PAgP or LACP or Trunk protocol negotiation"
http://www.cisco.com/c/en/us/support/docs/switches/catalyst-6500-virtual-switching-system-1440/109547-vss-best-practices.html
Is anyone else connecting a WLC LAG to a VSS MEC and if so what channel-group mode are they using?
Thanks
Andy

Hi,
I have never connected a WLC to VSS, but WLC should be threaded just as an access switch and use LACP or PAgP to connect to both VSS switches.

Change channel group mode without down time.

Hi All,
I'm trying to find a way to change the channel group mode on our access switch from mode on to mode active.
The port on access switch and core switch are configured like this : channel group X mode on
The goal is to change this config to channel group X mode active with no down time of the switch.
Please let me know if you have any ideas to do that.
Fabien.

I don't think its possible to change a Channel Group Mode without downtime.
Changing from On to Active will cause the port to start sending LACP messages in order to form an LACP Port-Channel.
As you are taking a link down, I suspect spanning-tree will also try and reconverge.
The downtime should be fairly minimal though, do you have a maintenance window?

Channel-group command

Could someone point me to a link about information about this command besides its options and such. If you dont know of a link but know the command, some of the questions I'm having include:
(1) what are the benefits of this command and why would you use this configuration?
(2) What platforms will this work for?
(3) If using between two switches and lets say you have four fiber links between the two, can you put three of the links into a channel-group and leave the other link out of the channel-group?
(4) Do the interfaces in the channel-group have to be in the same slot (same switching module) to be in a channel-group?
(5) Again, if you have two switches connected by four fiber links and you put each side of interfaces in a channel-group, do both sides have to be the same channel-group number?
(6) Neglecting that it is a hardware or line problem, what might be the reason for some of the interfaces in a channel-group to come up while others dont assuming that all the interfaces are configured exactly the same?

(1) what are the benefits of this command and why would you use this configuration?
>> channel-group x mode is an interface configuration to group identical interfaces in a combined logical interface, think of it as small pipes being combined to create a bigger pipe so that you can have more flows.
(2) What platforms will this work for?
>> channel-group is specific to catalyst running IOS like 2950, 2955, 2960, 2970, 3550, 3560, 3750, cat4000 with sup II+ or above, cat6000 with sups running Native IOS. For catalyst running it will be "port channel" command.
(3) If using between two switches and lets say you have four fiber links between the two, can you put three of the links into a channel-group and leave the other link out of the channel-group?
>> yes, by virtue of channel it will have a lower cost than the single interface therefore STP will block the single interface because it has a higher path cost to the root (STP can be discuss in a separate discussion).
(4) Do the interfaces in the channel-group have to be in the same slot (same switching module) to be in a channel-group?
>> No it does not have to be but they have to be identical. You cannot channel two ports where one is 100 MB and the other is a gig port.
(5) Again, if you have two switches connected by four fiber links and you put each side of interfaces in a channel-group, do both sides have to be the same channel-group number?
>> NO, channel group have local significance. If on switch A port 1 and 2 are in channel-group 1 and port 1 and 2 are connecting to port 3 and 4 of switch B. In switch B port 3 and 4 can be in channel-group 2 or 3 or 1 if you want to keep them the same for administrative sanity.
(6) Neglecting that it is a hardware or line problem, what might be the reason for some of the interfaces in a channel-group to come up while others dont assuming that all the interfaces are configured exactly the same?
>> cabling not right, interfaces in the same channel group are not alike, problem with the other end, or bug but this seldom is the case.

Why don't channel-group numbers match on a VSS port-channel link?

Hi All,
I have two 6509's that are VSS'd together via four 10gig links on each side. The configuration was done before I started this job, but in reviewing the configs I see that the 10gbps VSS heartbeat links are port-channeled together on each side, but one side is channel-group 2, while the other end of the bundle is channel-group 1.
I thought that channel-group numbers needed to match on both ends of the port-channel for it to form correctly?
I'm guessing that this has to happen because the switches are virtually one, so you can't put all 8 links into the same channel-group number or there would be nothing to connect to on the other side. Therefore, the "switch virtual link #" command is the real code that tells the switch where the other end of the link is, regardless of channel-group number, correct?

Dean,
The channel-group number does not have to be the same on each end. The four ports on switch A have to be in the same channel-group, and the four ports on switch B have to be in the same channel-group, but there's no communication across that line about what the channel-group is called. It's just a name. From a design standpoint it is nice to have them the same on both sides, but it's not always simple to allow for that in the design of a network.

Channel-group on 2 switches

I have 2 Catalyst 3560 24-port switches (call them switch-a and switch-b). They are linked together with a patch cable and not stacked (the c3750 is stackable but not the c3560). Is it possible to have a port-channel group with 2 ports, where one port is on switch-A and the other one is on switch-B? If not, is it possible if the 2 switches were stackable like the c3750 switches? Many thanks in advance. -Sam

As Jody already noted, 3560 (not stackable) no, 3750 (stackable) yes.
Other Cisco stackables, such as the 3650 series, 3850 series and 2960S (and later) series, also allow port channels across multiple physical switches (when stacked).
But, beyond stackables, you could also have a port-channel across two Cisco physical switches, if they were a VSS pair (one logical device, so much like a stackable) or Nexus pair (two logical devices). The latter's vPC (virtual port channel), is the "interesting variant", as, in theory (?) it could be implemented on something like a 3560 or other non-stackable switches, but don't hold your breath. ;)

4500-E vss MEC

Hi all,
I was reading today that Cisco Release IOS XE 3.4.0SG does not support Layer 3 MEC on the 4500 platform.
I would like to configure my MEC and run OSPF on my UPLINK. I would also like to prioritise 1 uplink over the other.
Would something like this work or can someone recommend a better solution not too sure abut the ospf cost.
thank you

So you are having two etherchannels to the same device ?
I'm just not sure why you are using two etherchannels as one should give you the redundancy ie. if one of the 4500s goes down you still have the connection from the 3550 to the other 4500.
Again though, like i say it could be due to may lack of knowledge in terms of VSS.
Hopefully Reza can add to this.

Re: Primay IDE channel Transfer mode is set to PIO mode - Enabling DMA Stat

Hi
I have installed Xp Professional Recently on my desktop ...
My Primay IDE channel Transfer mode is set to PIO mode...even if i try to change to DME if available its not changing....
I tried a option to run a VB script to change the DMA status but no luck..
Can anyone help me know if any option is available to change the DMA status

Hello suneel
Sorry to interrupt this discussion but I feel it goes somehow in wrong direction.
If I understand you right you just want to install WXP on your Satellite A300. Am I right about that?
On this forum you can find, I believe, hundreds of threads with precise description how to do this.
What you need is WXP installations CD with integrated SATA driver.
Check please this page . There you can find nice description how to find SATA drivers. At the end you can also find link to guide for "Slipstreaming SATA driver into WinXp boot cd using nLite".
When the WXP is installed just continue with WXp driver installation. If your notebook is WXP supported you can find them on Toshiba download page.
Hope this helps.
Good luck!

Removing port from channel-group

I've run into an odd issue with port aggregation where I decided to remove a port from a port channel and put it into another but in my SNMP tool it still belongs to the old port channel and the new simultaneously.
The port channel was created by using:
(config)#interface gigabitEthernet 1/0/22
(config-if)#switchport mode trunk
(config-if)#channel-group 1 mode active
And then changed through
(config)#interface gigabitEthernet 1/0/22
(config-if)#no channel-group 1 mode active
(config-if)#channel-group 2 mode active
I also get this when I pull information on etherchannel.

Could this be an issue with my snmp tool (observium) or are there any additional steps for removing a port from a channel-group? Switch restart?
System image file is "flash:c2960s-universalk9-mz.150-2.SE4.bin"

Hi,
I would say that this is related to the snmp tool, once you remove the port from the previous channel and added to the new it will belong to that one only, there is no way that an interface will below to 2 different port channels.
Also there is no need to restart the switch or anything like that, you can use the following commands to confirm that the interface is now part of the new channel group:
Show etherchannel summary
Show run interface gi1/0/22
With those commands you will see that the interface belongs to channel group 2, and the command you attached above shows that the interface belongs to po2.
Hope this helps

Channel grouping or stereo downmix

a bit confused about the differeence between channel grouping or stereo downmix in the audio settings of the sequence settings. i've used channel grouping forever but it came up that maybe i should be using stereo downmix sice the ultimate output is stereo. for example in my current project i'm using using 4 channels on the timeline. channels 1 & 2 are stereo, panned left & right (though not linked since levels are different for each). channels 3 & 4 are centered. would there be a difference in the outputed audio. tried it both ways and sounds the same.

Hi,
If Express features the "grouping" feature for
channel tracks, then you can use it.
(Pro)Manual, page 276, subheading "Groups"
Cheers
Hi and thanks for the reply,
Search as I may it appears Logic Express has no Grouping feature and there is nothing in the Express manual regarding grouping. I guess it's one of the reduced features compared with Pro.
Thanks

Disable Cache mode for a specific Mailbox

Hi
Is it posibble disable cache mode for a specific mailbox ??

As per the information and details provided by you, to disable Cache Mode for a specific mailbox, please follow these steps: -
The information provided by
Amy.Wang is correct, Exchange has no built in function to disable cached mode for a specific mailbox. And to
configure Cached Exchange mode setting by using Group Ploicy, please follow these steps: -
To do this, first you need to download
custom administrative template.
Download and extract the templates to your domain controller.
Start > Admistrative tools > Group Policy Management Console > either create a new policy and link it to your
USERS or edit an existing policy.
Navigate to:
User Configuration > Policies > Administartive Templates
Right click >
Add/Remove Templates.
Add > Navigate to the folder where you extracted the templates >
ADM Folder > en-us folder (change depending on your locale) > Outlk14.adm > Open.
Now Navigate to:
User Configuration > Policies > Administrative Templates > Classic Administartive Templates > Microsoft Outlook 2010 > Account Settings > Exchange > Cached Exchange Mode.
Locate “Use Cached Exchange Mode for new and existing Outlook profiles”
Set the policy to
Disabled > Apply OK > Close the policy editor. Locate “Use Cached Exchange Mode for new and existing Outlook Profiles”
Then get the clients to log off and back on again, wait a couple of hours, or manually run
“gpupdate/ force” on them.
I hope this information will be helpful for you.
Thanks and regards

Channel-Group on 5508 Controller

Ok .. I have an odd question regarding creating channel groups to connect 5508 controllers to my network.
Today I have a single 5508 Controller and it is attached to the network using two interfaces configured as a channel group. I am in the process of adding a second controller to be an HA for the existing controller. Here is my question. Do I simply add the interfaces of the new controller to the existing channel group or do I need to create a unique channel group for the new secondary controller? I am thinking that the channel groups are basically a point to point type connection and are basically connection specific right?

Assuming you aren't doing VSS. I keep the channel numbers the same on both side.
See below:

ASR - IPSEC, GRE, channel group, and MTU Questions

I have an ASR1004 and am trying to load-balance a 1.5G data rate over two 1-Gig ports using IPSEC ports, but I have a few questions.
1. Can GRE support a 9K mtu
2. Can you run IPSEC on a channel-group
3. Can the ASR load-balance per- S&D on a channel-group?
I currently have two separate tunnels, one on each outbound gig link with OSPF running. However, I can't get a 7000 mtu w/ the DF bit set through to the distant end. I am guessing this is because of the GRE interface.
So is it possible to run IPSEC on a channel-group and have this load balance per S&D? I need to use the BW of both ports.
Thanks for the help!

The ASR1004 router we can only send packets with a maximum MTU size of 1438 Bytes over the encrypted tunnel.
