Channel-group limit per router

Can someone make clear statement about limit of channel-groups (from VWIC2-2MFT-T1/E1) per router (i.e. 2811) ? I have 2 controllers with total of 4 E1 lines, but it sounds that I can ONLY have 4 channel-groups of any combination in a time per router.

Two channel groups can be supported per VWIC2 module. When a 2 port VWIC2 is used, only 1 channel group is supported per por

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.

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.

Per VRF label or Per route label

Folks,
A few weeks back I saw on some study group somewhere that im on a decent conversation on the downfalls of per vrf labels (juniper) compared to per route label (cisco). Now per route label obviously has its limitations in label consumption but per vrf label threw up a few issues - one of which was something to do with sub optimal routing. Anyone know any downfalls of using per vrf label space?

Rob,
One of the disadvantages of per VRF label scheme is that it requires an IP lookup on the edge router. This is due to the fact that if the label is shared among all CEs on a given PE, an IP lookup needs to be done in the VRF to determine which CE we should send the label to.
Another disavantage would be that you couldn't support CsC using a per VRF label since an IP table lookup is required on the PE, which breaks the end to end LSP.
On the other hand, you are absolutely right about the increase resources comsumption when a per route label scheme is used. This affects some vendors more than others though.
Hope this helps,

(This is of course only an excerpt. There may be more blocks and there will be more size channels and more channel groups...)
Now, I want to store the dN values in one channel group, the dN/N in the next group etc. There should be 10 channels, one for each size class, and the data from the various blocks as sequential values in these channels. (I hope I wa able to explain this in a comprehensoble way...)
I can generate the groups and the respective channels:
set oChn = ochngrp.Channels(2) 'Der Kanal mit den mittleren Dm wird für die Kanalnamen der Gruppen weiterverwendet
for i = 1 to 25
sMyLine = file.getnextline
aChnData = split(sMyLine,vbTab,-1,vbTextCompare)           'Read one line and parse it into an array
if not Root.ChannelGroups.Exists(aChnData(0)) then          'test if a group named like array(0) exists
    Set oChnGrp = Root.ChannelGroups.Add(aChnData(0)) ' and create one if necessary.
    for j = 1 to oChn.Size
      call oChnGrp.Channels.Add("" & oChn(j),eR64)                'add empty channels
    next
end if
next
How would I read the data?
With a lot of nested i,j-for..next loops, I could read a line via
for j = 1 to root.channelgroups.count
         aValue = split(file.getnextline)
         for i = 1 to 10
                root.channelgroups(j).values(i) = aValue(i)
         next
next
' then jump to timestamp of next data block with some skiplines, read timestamp and reiterate
or I could try to read all values for one channel group and use skiplines, e.g.
for i = 1 to root.channelgroups.count
   while file.position <> file.size
         aValue(j) = split(file.getnextline)
         file.skiplines(as many as are between the blocks)
   wend
' now I have a 2dim array aValue to transfer into data channels.But how?
file.position = 1
next
Could file.GetStringBlock be of any help?
Has anybody tackled a similar file structure and could give me a clue or some code sniplet?
Thank you...
Michael

Hi Michael,
I would just go line by line in the data file and send the array channel values (one value at a time) to the Channel.Values() property of the matching channel name. It's not going to be fast any way you do it in VBScript.

Group and Group counter in Routing

Hi all,
what is group and group counter in routing , how these are used in routing , please explain.
Regards,
Joseph.

Dear Joseph,
1.Each routing is stored against a group and group counter no.
2.When we create routing without respect to any material and only by giving the plant,the set of operations gets saved under one
group counter and group no.
4.Many materials can be assigned to this same group and group counter no,so that the routing is valid for all the materials included.
5.When you create a routing for material specific,the set of operation gets saved in a group no and group counter no as 01,when
you create another routing with another set of operations for the same material,plant and task list combination now the group no
remains same and the group counter gets saved under 02.
6.This data can be further helpful in assigning the routing data in the production version,.
Check and revert

BUG: Record Limit per Document doesn't work for PDF in CS4 - does it work in CS5?

Hey all - I'm attempting to export 100 data merged documents to pdf. I know i can use "Record Limit per Document" set to 1 to create 100 InDesign files, which isn't what i want to do. When you select "Export to PDF" in the data merge window, the "record limit per document" option exists, but no matter what, it will always create one giant pdf file - it will NOT separate into 100 different pdf files. This is a bug in CS4.
I am wondering if the bug has been fixed in CS5 or if there is a workaround in CS4 to generate the pdfs.
All I found is this ancient thread in which people say the only workaround is to batch convert the pdf files later, and then degenerates into unrelated discussion:
http://forums.adobe.com/message/1110826

g'day there
has there been any follow-up to this or workarounds?
i constantly have VDP jobs which have tens of thousands of records, but the chaps printing it only want the PDFs in lots of 500 or so. being able to do ONE merge which splits the merge into bite-size PDFs for our printing section would be preferable to making them through the dialog box in the appropriate lots.

How do I check to see if a channel group exists in the data portal?

I have a list of channel groups in the data portal but sometimes some channel groups are not created all the time. How do I check using a script if a channel group exists or was created.

Hello jreynolds!
With the command 'GroupIndexGet'. It returns 0 if the group does not exist.

Error -2500 while writing new channel groups / channels to tdm-file

I'm creating a tdm-file using the express vis provided by LabView. Everything goes fine in opening the file and setting the file parameters.
When i'm using the write data-express vi to create a new channel group and setting it's parameters i receive an "error -2500" accompanied with the call chain of the vi.
I'm setting the parameters by using a terminal on the express vi and by using the value setting in the express vi configuration. Any ideas what might cause this error?

I solved it. I made the error to begine some of the properties names with a number, eg. 1s for 1 sigma. I renamed them to sigma_1s and it works.

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. ;)

Cost Per hour, Costs per route not updating in S114 structure

Dear PM Guru's,
i am using MET unit system for vehicle consumption analysis. After completion of measurement documents and material issuance through IFCU, i checked the MCIZ report , but there i could not find the value of Costs per Hour, Costs per route information. I am requesting you all please guide me where i did the mistake either in "Configure measurement document updation" or calculation method?
I am eagerly waiting for replies.

Its not possible to give any specific section where it might have gone wrong. Suggest you to check the complete configuration under Settings for Fleet Management. Also check the configuration in IMG - PM & CS - Information Systems - Configure Measurement document update

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.

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.
#show interfaces gigabitEthernet 1/0/22 etherchannel
Port state = Up Mstr Assoc In-Bndl
Channel group = 2 Mode = Active Gcchange = -
Port-channel = Po2 GC = - Pseudo port-channel = Po2
Port index = 0 Load = 0x00 Protocol = LACP
Flags: S - Device is sending Slow LACPDUs F - Device is sending fast LACPDUs.
A - Device is in active mode. P - Device is in passive mode.
Local information:
LACP port Admin Oper Port Port
Port Flags State Priority Key Key Number State
Gi1/0/22 SA bndl 32768 0x2 0x2 0x117 0x3D
Partner's information:
LACP port Admin Oper Port Port

Gi1/0/22 SA 32768 0817.35e4.2c80 26s 0x0 0x2 0x118 0x3D
Age of the port in the current state: 164d:21h:32m:44s
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?

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
