HSRP group question

If you have multiples VLAN SVIs configured with the same HSRP group, does changing the priority on one SVI to failover to another router cause all the SVIs in that group to switch to the other router or do the individual priority settings keep that from happening?

I would think that since you configure the priority in interface config mode (not in global config) that it would affect only the SVI on which you configure it.

  • Can multi-interfaces share the same hsrp group id on the c6500?

    case:
    c6509A+msfc2 and C6509B+msfc3
    configurating hsrp...
    question:
    msfc2 supports total 16 hsrp group id,however msfc3 256.How hsrp group Can configurate?How vlans can configurate inside the same group id?

    Hi,
    MSFC2 supports only 16 HSRP group duw to the limitaion on PFC2.The new MSFC3 supports 256 HSRP groups as you mentioned above.
    The workaround to get over this problem is to use multiple Vlan interface to a single HSRP group like
    Vlan1,3,5,7 in HSRP group 1
    Vlan 2,4,6,8 in HSRP group 2.
    It works perfectly as already pointed out by Glen.

  • Multiple members of HSRP group - implications?

    I've got a group of 6509's that support a couple dozen IP networks. Recently we ran into the "16 HSRP groups" limitation.
    My question is, if I assign multiple VLAN's to a single HSRP group, and one of the member interfaces becomes unavailable, do *all* members of that group go from active to standby? Or just the affected IP/VLAN?

    Hi,
    it effects on that particular Vlan not the entire HSRP group.

  • HSRP Group Limitation Problem

    Dear All,
    I have 2 3750 switches on which I need to configure HSRP for 26 VLANS.
    I have tried configuring one group for vlan 1 - 16 & second group next 16 VLANS. But i still get the error 'platform does not support more than 32 hsrp groups'
    What seems to be the problem?
    Thanks in advance.
    Sridhar.

    Have you tried to assign unique HSRP group numbers to the 26 different groups you need?
    32 HSRP groups is an HW limitation of the 3750 with no workaround available, unlike the 3550 where you could get creative with clumping groups of vlans and re use HSRP group numbers as outlined in:
    http://www.cisco.com/en/US/products/hw/switches/ps646/products_qanda_item09186a00801cb707.shtml
    The other thing to consider would be version of IOS.

  • NATing to the virtual MAC address of an HSRP group problems...

    Hello
    I have a problem where I need to NAT various IP addresses, and need the NATd addresses to carry the virtual MAC address of the HSRP group on the onward travels..
    By default, with the Cisco 871's I'm using, the packets are NATd, but carry the MAC address of the external interface.. not the virtual MAC address.
    The problem is that when I failover to the standby 871, the packets will then have the MAC address of the standby (new active) 871. This causes problems because my next hop doesn't update its ARP tables (very infrequent updates).
    The next hop will accept packets NATd by the standby (now live), but will continue to send reply (eg ICMP) to the live (now standby) because it hasn't updated its ARP table.
    I know that I can create a NAT pool with the virtual IP address as the only member of the pool. Packets will then have the virtual MAC address, and the problem will be fixed, but if I need to NAT IP addresses to *different* NATd addresses, then I would have to create multiple HSRP groups, with different virtual IP's and MAC's, and then create multiple NAT pools...
    If I can't get my next hop (which I have minimal control over) to refresh/update it's ARP table, then I will consider the multiple HSRP group config, but before I try that I would like to know whether I would be able to have multiple virtual IP's and MAC's on a single interface. Apparently there was a problem with the Catalyst 2500/4500 series where the same MAC address would be used for all HSRP groups, and you had to use burned-in MAC addresses for HSRP groups.. which wouldn't provide a solution in this case..
    Any ideas on how to fix this would be greatly appreciated. BTW I have proxy-arp on external interface, and gratuitous arp.
    My software version is:
    Cisco IOS Software, C870 Software (C870-ADVSECURITYK9-M), Version 12.3(8)YI1, RELEASE SOFTWARE (fc1)
    Synched to technology version 12.3(10.3)T2

  • HSRP groups / Limit of 32 reached

    Hi there,
    Sorry in advance, I speak English with difficulty...
    I have a problem with my network core: The limit of 32 groups is reached.
    But I have only 32 standby IP address in the group 0...
    The message "% More than 32 standby groups not supported in this platform" appeared...
    At the moment, I'll create the others groups on others network core, but this solution is temporary.
    My network cores: WS-C3750G-12S-S
    iOS : 12.2(35)SE5 IPBase
    So, I have two questions for you please :
    Actually in IPBase version, if I will upgrade my switchs with IPService version, is it solved the problem ? is the iOS "IPService" support more than 32 groups ?
    Is there an other solution to ensure failover that works like HSRP ? (VRRP ? how many groups are supported ?)
    Any other issue or idea is welcome...
    Thank you for all

    Hi,
    The maximum amount of 32 instances is the same for HSRP, VRRP and GLBP this is a hardware limitation not a matter of a IOS feature set. That said even if you upgrade to ipservices the amount of groups will not be higher.

  • Multiple Artwork Covers Issue & Grouping Question

    My favorite band is The Smashing Pumpkins. Their latest album +Teargarden by Kaleidyscope+ is being released one song at a time online for free and in 11 different limited EPs that will compose the whole album. My problem here is that there a two artwork covers, one for the entire album and a second for each EP (only one EP has been released, the first song for the second EP is out). The first EP displays with the EP cover but the one song from the second EP only displays the overall album cover. How do I get my Classic to display only one cover instead of picking randomly (as it seems)?
    The following question deals with the same album. I want to group the EPs that are to be released in the future so that on my Classic I see only one big album instead of multiple EPs. Unlike their Machina II these EPs have subtitles for them. What I am wanting is one album cover to display (the overall album artwork), the name to display as +Teargarden by Kaleidyscope+ not +Teargarden by Kaleidyscope Vol. 1: Songs for a Sailor+ which is the name of the first EP in the album section of my Classic. Is all of this possible?

  • Authenticated Users Group Question

    I have a quick question regarding the Authenticated Users "group". I used to be a systems administrator, but I'm a bit rusty since I've been a software developer for the last 10 years. A conflict with data center operations (DCO) group
    at work lead me to get another opinion.
    The question is this... is the authenticated users group a domain-level group or is there a local authenticated users group that would allow only users authenticated locally? We have a share that permits the authenticated users group access.
    My opinion is that all domain users who have authenticated successfully have access to this share. The DCO group is telling me that this is the local (to the server containing the share of course) authenticated users group only.
    Is there such a thing as a local-only authenticated users group? To me this doesn't even make sense, but I could very well be wrong.

    I apologize. I don't think I explained myself correctly. Let's consider the following...
    SERVER: SERVER1
    DOMAIN: DOMAIN1
    SHARE: \\SERVER1\SHARE1
    SHARE PERMISSIONS: Authenticated Users - Full Control
    Given the above information, is it possible that the Authenticated Users group will allow ONLY users that are defined on SERVER1 to access \\SERVER1\SHARE1?
    My understanding is that's not possible. There's one defined Authenticated Users group and that represents ALL users that are authenticated against DOMAIN1, whether added to local groups, shares, etc.
    What I'm being told however is that SHARE1 having Authenticated Users assigned is okay since only those user accounts defined on SERVER1 will be able to access it. All the users in the domain will NOT be able to access it. I think this is bogus. Am I wrong?

  • A few SQL related protection group Questions - DPM 2012 R2

    Hi - Here is my environment: DPM 2012 R2 backing up SQL 2012 DBs. Some of the DBs are simple recovery model, some are full recovery model in the same protection group.
    1) Regarding the fact that DPM only looks to the recovery model when the DB is first added to the protection group, if I ever changed the recovery model in the future, would stepping through the "Modify Protection Group" wizard without changing
    anything be the solution for DPM not changing its methodology on the backing up or not backing up the log files? Or would I have to remove the affected databases from the protection group and add them back in?
    2) I have disk protection configured for 30 Days, sync every 15 minutes, and application recovery points once per day. Online protection is configured for 90 Days. Does this mean my disk consumption on the DPM side for full model databases will be the full
    size of the databases, plus the amount of changes observed over 30 days? OR does it mean it will keep 30 full copies of the DB? I am fairly sure the former.
    3) If I do decide to reduce the retention range on the disk side of this protection group to say 14 days, are there any specific issues with changing that after the PG has been working for some time?
    4) My former backup solution had an option to run consistency checks after every SQL job. Is that still considered best practice? Would the "Run a daily consistency check" be a better choice than the "Only run if a replica becomes inconsistent"
    option that I currently have in place? Would there be any ramifications to enabling this now after this PG has been in place for some time?
    Thanks very much!

    Hi
    Q1) Regarding the fact that DPM only looks to the recovery model when the DB is first added to the protection group, if I ever changed the recovery model in the future, would stepping through the "Modify Protection Group" wizard without changing
    anything be the solution for DPM not changing its methodology on the backing up or not backing up the log files? Or would I have to remove the affected databases from the protection group and add them back in?
    A1)
    Changing the Recovery Model of a Database
    To change the recovery model of a protected database to the simple recovery model
    Stop protection of the database, selecting the retain replica option.
    Change the recovery model on the SQL Server database.
    Add the database to a protection group.
    Q2) I have disk protection configured for 30 Days, sync every 15 minutes, and application recovery points once per day. Online protection is configured for 90 Days. Does this mean my disk consumption on the DPM side for full model databases will be the full
    size of the databases, plus the amount of changes observed over 30 days? OR does it mean it will keep 30 full copies of the DB? I am fairly sure the former.
    A2) Your disk consumption on the DPM will be for size of model databases plus the amount of changes observed over 30 days.
    Q3) If I do decide to reduce the retention range on the disk side of this protection group to say 14 days, are there any specific issues with changing that after the PG has been working for some time?
    A4) Not really, but to gain back the potential extra space allocated for the original 30 day retention - you can try shrinking the recovery point volume once the retention range is reduced and the older recovery points are pruned.  I would wait until
    after midnight to be sure the old RP's are deleted, then try to shrink.
    Q4) My former backup solution had an option to run consistency checks after every SQL job. Is that still considered best practice? Would the "Run a daily consistency check" be a better choice than the "Only run if a replica becomes inconsistent"
    option that I currently have in place? Would there be any ramifications to enabling this now after this PG has been in place for some time?
    A4)  A consistency check will only run if DPM detects the replica is inconsistent.  Even if you have the option selected to run nightly, if the replica is already consistent a consistency check will be skipped.

  • Hierarchical Tree Data Query/Record Group Question

    I need help with Hierarchical Forms right now. I'm currently trying to implement a hierarchical tree to display the different items in different categories. I have been reading up on it for the past few days, and i do not understand a few things.
    What is the difference between a data query and record group? they seem the same to me.
    How does the XX = prior XXX work? i understand that this is what connects the parent to the child.
    How do you determine what depth the node is? its done in the record group/data query, but how do i decide what level it is dynamically?
    Thanks a lot in advance!

    Thanks! I am unable to create a table specifically for the tree because i am using tables that have been ported live and are in use. My question about levels is how do I know which depth the node is. For example, i have a category called Information Technology and a category item called Business Informatics. I want to know how to decide that the Category(information technology) is on level 1 and the Item(business informatics) is on level 2.
    Information Technology
    |_
    Business Informatics
    And i do know how the Connect By XX = prior XXX works in the data query/record group.
    Thanks for your help!

  • Address Book Smart Group question

    Hello all,
    I want to create a Smart Group in Address Book that compiles people according to their job title.
    For example a group of everyone whose job title is 'Manager', i.e. Job Title contains Manager. But for some reason Job Title is not in the list of options when creating a Smart Group.
    Is there a way to make it work?
    Also, (a question for all the Snow Leopard users) is the option for Job Title there in OSX 10.6?
    I'm using Tiger 10.4.11.
    Thanks all.

    There is no such field for Job Title by default. If you select the Add Field item from the Card menu you can add that field to a card. However, I do not see Job Title as a search field for a Smart Group. I assume this is a bug which you can report here: Feedback.

  • PCNS Inclusion Group question

    Hi,
    To ensure PCNS works correctly, I assume you have to be part of the Inclusion Group at the time of your password change?
    The scenario I am thinking of is where FIM manages the membership of the Inclusion Group...and the user changes their password before a FIM export updates their Group membership...I guess PCNS won't magically start working once they enter the correct Inclusion
    Group?
    just some wishful thinking ;)

    Yes, you understand it correctly - password would be changed only in the user's domain and would not be propagated to other directories.

  • Advanced filtering/grouping question (pivot-table?)

    Ahoy. I have come across a few flies in the final varnish of an image database I'm working on. I don't yet know the best way to ask the question. I think what I am looking for is some kind of pivot-table like grouping capability. I think I could do this with nest-able Smart Albums -- but you can't nest Smart Albums in Aperture. (Journler, for those who used it, had, imho, a brilliant implementation of nest-able filters.)
    Let me give what should be able to serve as a good generic example: a Library of dog images. These are organized into Projects based on shoots. The images are keyworded with the dogs' breeds, their type, their coat type and color, their individual names (when known), and other "normal" dog characteristics (gender, age when known, etc.). There are also some special keywords, such as a set for expressions (Relaxed, Angry, Teeth Bared, Questioning, Attentive), and, where needed, details of ailments (Sore, Rash, Teeth, Gums, Wound).
    I have set up Smart Albums to show many of these, e.g.:
    . Spaniels
    . Huskies
    . Retrievers
    . Cocker Spaniels
    . Labrado Retrievers
    . Details of Angry expressions
    etc.
    The database problem I am trying to resolve is: how best to narrow selections of groups of Smart Albums? Using the example above, for instance, I have Smart Albums to show me all the detail images of expressions:
    . Dog is Angry
    . Dog is Attentive
    . Dog is Asleep
    . Dog is Tired
    . Dog is Questioning
    . Dog is Relaxed
    How best to narrow those to, for instance, just Huskies? or just Working Dogs? or just the individual dog known as "Nanook's Shadow"?
    Clearly, if each of those is a keyword (or a keyword container), I can simply add the keyword to the Filter. But I want much greater functionality than that.
    By "best" I mean to include the ability to change the variable -- to chose not just "Huskies", but also "Retrievers", and not just "Working Dogs" but also "Hounds". And I want to change this at once -- not individually for each Smart Album.
    What I've come with is clever and borders on elegant (imho - ), but remains a kludge.
    Smart Albums can be subordinate to only Projects and Folders. Subordinating them to Projects does me some, but little, good. (Subordinating them to other Smart Albums, or to regular Albums, would do me more good, but is not allowed.) I therefore created a new parent Folder for each set of Smart Albums I wanted to be able to readily filter as a group, and copied a set of Smart Albums into it. I then set each Smart Album's "Source" to the containing Folder rather than to "Library". At this point, the Smart Albums show no images, which is good. Now, all I have to do is create an Album of images I want the Smart Albums to operate on, and drag that Album into the containing Folder. So I go to my "Hounds" Smart Album, select all images, create new Album with selected images, and drag that into my Folder "Dog Expressions". The Album filters the universe of my Library to just "Hounds" and the Smart Folders filter from that narrowed group.
    This is relatively flexible: If I want to include "Retrievers" as well as "Hounds", I just make another Album and drag it into the "Dog Expressions" Folder. If I want to see only Retrievers, I drag the "Hounds" Album out of the "Dog Expressions" Folder. (So I made a holder Folder called "Sets for Smart Albums" and I keep Albums such as "Retrievers" and "Hounds" there.) I now have a relatively supple drag-and-drop method of filtering groups of Smart Albums all at once.
    But you can already see the problems. First among them is that the Albums are static. I will need to create new Albums in order to include any new images or Versions or whenever I get around to keywording, etc.
    Still with me? Can you help me do better?
    Is there any reason one couldn't have a pivot table based on metadata? One which not only filters but also groups, so that I could have a view showing (for instance) details of Huskies expressions grouped by expression?
    Thanks in advance. If this catches you on Friday, enjoy the weekend.

  • Terminal: "open -e/t" question.  Windows group question

    2 questions regarding Terminal
    1. Is it possible to make it so the open -e, or open -t command, instead of opening TextEdit, opens a different text editor?
    2. Is it possible to open a Windows group, and have JUST 1 of the windows execute an ssh command?

    1. Is it possible to make it so the open -e, or open -t command, instead of opening TextEdit, opens a different text editor?
    Sure. 'open -t' uses the default text editor application, as defined by LaunchServices. On a standard system this is TextEdit.
    If you want to have 'open -t' use a different TextEditor then you need to specify an alternative application as the default text editor.
    This is easiest done by selecting a plain text (.txt) file in the Finder and choosing File -> Get Info. In the 'Open with' pane you can choose an alternative text editor and clicking the 'Change All' button will update the LaunchServices database with the specified application as the default.
    Now any .txt file you open will launch in this application, whether it's opened in the Finder, or via 'open -t'.

    Hi,
    Can anybody answer below questions?
    1) Once assigned to a group how can you see the group from the delivery; it’s not in the document flow. I am struggling making this connection.
    2)If multiple deliveries are put into the same delivery group, can they be split into multiple shipments? This seems to be posslble but I am unsure of the
    3)Is there a delivery group monitor to track open (unshipped) delivery groups?
    4) Is there any T-code to group deliveries at IM level. i am sure abt LT45 and VG01 but both of them are at WM level.
    Thanks,

    Hi Bhairav,
               There is transaction code VL06o, I think this will help you out. Go to this transaction and click "List out bound Deliveries" it will take you in to next screen in that screen you go to Doc.Data there you can find Group field selection there you enter your delivery group and execute the report.
