Why AP Management Address is Untagged

Anyone want to venture a guess as to why Cisco doesn't allow a management address on an AP on a tagged interface?  I believe that it has to do with 'bridge 1 route ip' and that if you were to place a management address on another VLAN you'd be restricted by the 'bridge 1 route ip' command to only being able to manage it from that same VLAN.  I don't think it's possible to change the route ip statement to any other VLAN.  I'm in an environment where I have autonomous APs and VLAN 1 is shut down.  Need to manage the APs and can't think of a way to do it.
Regards,
Scott

The 1 in the bridge 1 route ip command is a bridge group number not a VLAN ID.
The BVI 1 interface is configured with the management IP address of the AP on bridge group 1 not VLAN 1.
Since the BVI1 interface is assigned to bridge group 1, management of the AP must be on bridge group 1.
The Ethernet Interface that bridge group 1 is configured on determines the VLAN using the encapsulation dot1q command.
The necessary VLAN tagging takes place by adding the native keyword option to the encapsulation dot1q statement on the Ethernet sub-interface for the management VLAN.
The switch port that the AP is connected to must be configured with this native VLAN.
The VLAN can be changed to any VLAN ID but not the bridge group which must be bridge group 1.
Here is an example for using VLAN 99 for management of the AP.
AP
interface FastEthernet0.99
bridge group 1
encapsulation dot1Q 99 native
interface BVI1
Ip address 10.10.10.10 255.255.255.0
SWITCH
Interface fa0/1
switchport mode trunk
switchport trunk encapsulation dot1q
switchport trunk native vlan 99
switchport trunk allowed vlan 10,20,99
The switch defaults to switch port trunk native VLAN 1 which is not shown in the switch configuration.
The VLAN 10 and 20 in the switchport trunk allowed vlan command are for two wireless SSIDs configured on the AP.

  • Why assign IP addresses to router/switch interfaces?

    I get why I would ever want to assign a IP address to a router or switch, for remote login and IP for hosts to reach it. But why assign IP addresses to the interfaces? Is it so the router/switch knows which port to send the packet out? Route summation? But I thought they do that through the routing table, like " that address is out this port".
    So why would we ever need to assign IP addresses to specific port interfaces?

    You normally assign IP addresses to L3 interfaces so other L3 devices have an IP address to forward traffic to.  (L2 IP address are generally only used for management.)
    Suppose you had Host (192.168.1.5/24) <> R1 <> R2 <> (192.168.2.8/24) Host, and you want the two hosts to intercommunicate.  How would you get this to work?
    You might started by providing interface IPs on the router interfaces facing the host, such as:
    Host (192.168.1.5/24) <> (192.168.1.1/24) R1 <> R2 (192.168.2.1/24) <> (192.168.2.8/24) Host
    You then configure "gateway" IPs on both hosts:
    Host (192.168.1.5/24 - GW 192.168.1.1) <> (192.168.1.1/24) R1 <> R2 (192.168.2.1/24) <> (192.168.2.8/24 - GW 192.168.2.1) Host
    Now each hosts "knows" to send all its off local subnet, traffic physically to the GW IP.  So, for example, if 192.168.1.5 want to sent to 192.168.2.8, it would forward the traffic to the GW IP, 192.168.1.1.  This is a example of why you want an IP on the router's L3 interface.
    Next we want R1 to forward the packet to R2, but it too needs a "next hop" IP address, so we assign addresses on the link between the two router, e.g.:
    Host (192.168.1.5/24 - GW 192.168.1.1) <> (192.168.1.1/24) R1 (192.168.3.1/24) <> (192.168.3.2/24) R2 (192.168.2.1/24) <> (192.168.2.8/24 - GW 192.168.2.1) Host
    R1 then needs to "know" where to send packets with an destination IP network of 192.168.2.0/24, in this case, it need to "know" to send the to IP 192.168.3.2.  When it does, R2, having and interface with 192.168.2.1, will also know 192.168.2.8 can be reached by sending the packet out that interface.
    Hopefully, the above will show why IP addresses on router L3 interfaces are needed.
    BTW, normally for the R1<>R2 link, you would assign a /30 or /31 network or you might use "unnumbered" interfaces (which "borrow" IPs from another interface).

  • Why Solution Manager is needed?

    Hello
    I just want to know why Solution Manager is needed? especially for SAP BI project

    Hi,
    First, Solution Manager is absolutely necessary to generate installation key for SAP product (i.e.ECC). Second, the new level of SP (released after Feb)  needs approval from saposs before downloading from ur download basket, so you always have to ask them to approve ur request. Using Solman, u can download the package automatically.
    The rest is, Solman offers many functionality to manage your systems easily by making it centralized, such as change / transport management, monitoring, document repository, configuration, and many more...

  • HT3952 Why can't Address Book allow me to add "spouse" to the print job?

    I can add "spouse" to a card, so why can't Address Book allow me to print the name on the card plus the spouse name? So if I try to print "Ravi" I have the option in the print dialogue to add "Mei"? Seems simple, even Word can do it.

    Hi,
    It doesn't look like the "Country" field on the cards need to match.  I changed one of the spouses to a different country and the label (as shown in the print dialogue panel as you suggested) still shows "John Smith and Jane Doe."  Most of my country fields are blank.
    It does matter that the Country Code be the same for both.  After selecting the card and clicking on edit, the Country Code can be checked or changed by clicking on the address label (home, work, etc.) and moving the mouse down to "Change Address Format..."  You'll see a long list of countries.  If the cards for Jane and John don't have the same country code, the label won't show both names.
    The lines of code like:
         <key>us</key>
         <true/>
    in the ABRelatedNamesConfig.plist file determine which countries the related names functionality will work in.  Using the plist shown in an earlier post, they need to live in ca (Canada), uk (United Kingdom), us (United States), or fr (France) and both need be be in the same one.  Adding other country codes to the plist file should enable that country to work as well (I haven't tried it).
    The related names functionality was removed with the release of Snow Leopard (10.6) so I've editied the plist file in 10.6, 10.7 and 10.8.  All have worked.
    The only other thing I noticed is that the following two lines shown in the earlier post are really one line in the plist file.
    As shown in the earlier post, the code:
         
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
    is really all on one line.  Here is a screen shot of my plist file as viewed in TextWrangler:
    The good news is we have 358 days to figure this out before Christmas.

  • Why is my address book not syncing with my icloud contacts

    Why is my address book not syncing with my icloud contacts?
    I have my desk top and I have an iphone. I seem to have 2 different contacts list, 1 from my mac and the other icloud. If i add adress on my iphone to contact it does not sync to "my mac"

    thank you very much that worked.first i thought if i restored then I would lose everything but of course I could re-sync so everything good now!!

  • Why does my address book not sync to iCloud?

    Why does my address book not sync to iCloud?

    I believe the duplicate address book accounts stems from the move from MobileMe to iCloud and both accounts still being active.
    This is how I merged the two address books:
    1) To make sure all the contacts are in both:
    a) I selected On My Mac account - clicked on any address - Command A to select all - drag the contacts to the iCloud account - answered OK to merge and resolve duplicates.
    b) same in reverse: select the iCloud account - click on an address - click Command A to select all - drag the contacts to the On My Mac account - answer OK to merge and resolve duplicates.
    In system preferences I found an iCloud icon and also a MobileMe icon. I was logged in under both.
    1)  In the Address Book preferences I selected iCloud and unchecked Enable this account.
    2)  In the Address Book I selected iCloud and clicked on the minus “-” to remove that account – leaving only the local Mac address book.
    3)  I went into system preferences and logged out of MobileMe
    4)  In system preferences I opened iCloud and the “Contacts” was not selected (from above) and I selected it.
    I got a dialog box asking if I wanted to merge the iCloud contact with the local contacts – clicked YES.
    … spinning wheel for a minute … voila – only one address book account – iCloud with syncing to iCloud and my iPhone.

  • Why does management VLAN ID matter in Cisco AP541n configuration?

    is working on configure AP541n AP,  is able to connect to the AP wired, assign AP static IP with proper subnet mask & default gateway,
    when it's done, everything looks perfectly, but since I changed the management VLAN ID from 1 to 2, I can't even connect to the AP wired from the PC, why does the change matter?
    thanks.

    Hi,
    When working with access points in IOS mode also known as autonomous the access point requiers that you configure an Ip address on the BVI1 which is linked to the bridge group 1 and set us untagged.
    Now when working with VLANS if the access point has an ip address on vlan x then you will need to confiugre this as the native vlan and with the bridgroup 1.
    If you do not do this then you will see the issue you are reporting.
    In other words if the access point will have an ip address for vlan 30 the the native vlan on the ap will need to be vlan 30 and vlan or the subnet for vlan one linked to the bridge group 1

  • Why is my address bar no longer retaining past sites that I have visited?

    My address bar used to save frequently used web addresses in a dropdown menu accessed by clicking on the down arrow at the very right of the address bar. Without warning, it now only retains the addresses I visit during a specific session. At the end of each session, the Dropdown memory is wiped clean. Why did this happen and how do I repair this huge inconvenience???

    -> click '''Firefox''' button and click '''Options''' -> Privacy -> History section -> '''Firefox will: select "Use Custom Settings for History"''' -> REMOVE Checkmark from '''Permanent Private Browsing mode''' -> place Checkmarks on:

  • Why is my address bar no longer using "predictive" (don't know the proper term) text anymore?

    For example, if I type in a letter such as "f," in the address bar, why does it no longer bring up the options of websites that are saved in my history and bookmarks?
    == I'm not sure, but I think it happened after I chose my new skin.

  • Why is the address bar not allowing search anymore?

    I have always searched on Firefox by just typing what I want into the address bar. It would bring up the Google results automatically. It just suddenly stopped working-like I did it while searching for one thing and ten minutes later opened a different tab and it didn't work anymore. When I do try to search from the address bar the screen says "Unable to Connect...Firefox can't establish a connection to the server at 'search term'. The site could be temporarily unavailable or too busy. Try again in a few moments. If you are unable to load any pages, check your computer's network connection. If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web."

  • Why did my Address Book disappear and how can I get it back?

    The Address Book application has simply disappeared on two of my MacBook Pros. I thought the first one (work laptop) was a fluke but now that it's happened on my own MacBook I think something is wrong.
    The app is no longer available anywhere on my hard drive. It's as if I threw it away, but I didn't. I can't open any associated files, so I don't even know if the data has been preserved.
    Can anyone help me figure out why it disappeared, where it went, and how to get it back, short of reinstalling OS X 10.5.8 (the version I'm currently using)? I want to upgrade to Snow Leopard (not Lion -- no one seems to like it), but I'd like to fix this problem first. And I can't upgrade on the work MacBook because I have to use the enterprise-approved OS version.
    Thanks!

    Amy, is there a chance they could both be Syncing to another device that has the data erased?
    What are the sizes & modification dates on the files you found?
    Could be many things, we should start with this to be safe, though 2 different ones would seem unlikely to be this problem...
