Vlan tag issue with Nexus 4001 in IBM Blade Centre

Hi
I have a DC architecture with a pair of Nexus 7010's running 3 VDC's (Core/Aggregation/Enterprise). I have at the edge Nexus 5548's which connect to back to the Aggregation VDC. Also connecting back to the Aggregation VDC is an IBM Blade Chassis which has a Nexus 4001i in slots 7 and slot 9. These blade servers are running ESXi 4.0 and are mapped to the Nexus 4001 blade switch.
I had set up the Native VLAN as VLAN 999 which connects up to the ESXi host and I am trunking up multiple VLANS for the Virtual Machines.
The problem I have is that VM's in all VLANS except the ESXi host VLAN (VLAN 10) cannot see their default gateway, and I suspect that there is an issue with the VLAN tag going up to the ESXi host. I have read enough documentation to suggest that this is where the issue is.
My Nexus 4001 interface configuration is below
interface Ethernet1/1
switchport mode trunk
switchport trunk native vlan 999
switchport trunk allowed vlan 10,30,40-41,60-62,90,96,999
spanning-tree port type edge trunk
speed auto
The Aggregation VDC on the Nexus 7010 is the default gateway for all these VLANS.
I also noted that the Nexus 5000 and Nexus 7000 supports the command vlan dot1q tag native command yet the Nexus 4000 doesn't seem to support this. Any assistance would be useful
Thanks
Greg

Your configuration on the N4K looks correct. You shouldn't use vlan dot1q tag native commands on your N7Ks and N5Ks. Native VLAN tagging is really for QinQ (dot1q tunneling).
My only suggestion is check your configuration of the vSwitch in the ESXi host and the host network profile.

jerry

Mesh Ethernet Bridging with VLAN Tagging Issue

Hi all.
I'm a little stuck with a 4400 7.0.220.0 + RAP 1550 + MAP 1260 Ethernet bridging issue. I'm using the VLAN tagging functionality and I'm finding that periodically a VLAN that I've tagged on the MAP will deregister from the backhaul and stop passing traffic. If I go into the Mesh tab on the MAP, select the wired interface, remove the VLAN from the list of tagged VLAN IDs and then add it right back to the list, its starts passing traffic again.
Has anyone else seen this? I can't find any relevant bugs.
Justin

Hi Saravanan,
It is one RAP and three MAPs. After a TAC call and 30 hours of monitoring, my VLANs have remained registered. I think the issue was mismatched VLANs to bridge groups an it looks like the mesh bridge may be stable for now. Here is what I was seeing on the RAP and MAPs when the VLANs were deregistering unexpectedly. Notice how VLANs 2 and 10 are mapped to opposite bridge groups on the RAP and MAP:
After I removed all the VLAN IDs from the Trunk configuration on the MAPs (through each AP's Mesh tab -- Ethernet Bridging config) and then rebuilt the VLAN IDs, I ran the same commands and now see this:
My very unscientific theory here is that the mismatching was causing consistency checks to fail, so the RAP was just tearing down the registrations after getting bogus or non- responses from the MAPs during the periodic VLAN registration maintenance checks (debug mesh ethernet registration).
If I have continued issues, I'll post back with updates.
Thanks for the response!

Continuing font encoding and tag issues with snow leopard and CS4oI

I am looking for help with a font handling issue with snow leopard and cs4 Indesign. Despite numerous calls and hours on the phone neither Apple nor Adobe has been helpful. I have had this issue open with Adobe since oct 5 but they remain totally unresponsive to date. I need to be able to use Type 1 fonts and do the following , export a pdf from Indesign with the following attributes: 1) xml tags for stories and objects. 2) have the fonts encoded as ansi and embedded.
Some additional information - exporting to ps is not an option as it destroys the xml tags. and doesn't guarantee that the fonts won't become CID or some other odd encoding.
As it stands now,
Leopard (10.5.8) and CS3 creates ansi encoded fonts with xml tags.
Leopard (10.5.8) and CS4 creates ansi encoded fonts with xml tags.
Snow leopard and CS3 creates ansi encoded fonts and xml tags
Snow leopard and CS4 creates custom subsetted fonts and some xml tags.
If any one has any advice on how to force specific font encodings from CS4 pdf exports so that i can preserve the tags and get the correct fonts I would be grateful.

The font encoding is not a function of the OS version, but rather of how a font is internally encoded and the content you are representing with the font.
If you are seeing a difference between MacOS 10.5 and 10.6 with the same Adobe software, it probably has something to do with use of a system font that is somehow different from one version of the OS to another. InDesign does not use any of the OS' font handling software.
Assuming that the fonts are embedded, subset or not, what is your issue with whether a font is ANSI-encoded, custom-encoded, or CID-encoded? It should make no difference for purposes of workflow beyond InDesign for software that adheres to the PDF specification (including all versions of PDF from 1.3 and up to 1.7 plus ISO 32000-1 PDF and all versions of PDF/X and PDF/A).
Neither InDesign or any other Adobe application provides user choices for the encoding since it shouldn't make a difference. The encodings chosen by Adobe's core technology components are for a combination of optimization and to support proper text search, copy, etc.

Multiple vlans configuration issue with RV016 router and SG 300-10MP witch

Hi,
I have to configure multiple vlans served with a unique DCHP server . As first step, I just will The DHCP server to serve 2 vlans. The following is the hardware and configuration that I implemented :
Router (RV016 10/100 16-Port VPN Router) as gateway mode:
IP : 172.16.0.1/24
DHCP Server :
IP : 172.16.0.2/24 GW: 172.16.0.1
2 subnets :
172.16.1.0/24 GW: 172.16.1.1 to serve vlan 1
172.16.2.0/24 GW:172.16.2.1 to serve vlan 2
Switch (SG 300-10MP 10-Port Gigabit PoE Managed Switch) as layer 3 mode:
IP 172.16.0.254 (vlan 8 default)
Vlan 1 : 172.16.1.1
Vlan 2 : 172.16.2.1
1 device connected on each vlan
a workstation on the vlan 1
a laptop on the vlan 2
In this scenario (see the attached pdf file) the DHCP server is connected on a router, hosts on vlans dont receive any IP address.
But If I connect the DHCP server on a trunked switch port and adapt the DHCP server gateway 172.16.0.1 to 172.16.0.254, hosts receive ip address properly.
I have to connect the DHCP server directly to the router. How can I do that, what is wrong in the configuration ?
I hope the explanations are clear enough and my English too
Any help will be highly appreciated,
Zoubeir

Hi Eric, the small business group doesn't support the ASA config, but I can help with the switch.
A couple things I notice in your description-
48 port (192.168.1.254) and the other 24P (192.168.1.253) we have a second vlan 20 set up on the 24P switch (192.168.2.253) we have ports 1-12 set for vlan20 (untagged and trunk), the remaining ports on on the default vlan 1.
The connection between the switches, is it 1u, 2t?
The link between the switches should be 1u, 2t, the switches support the trunking and vlan tagging, meaning all communication will work fine.
We have the 24p and 48p switches connect using GE1 and GE1. We are unable to ping a device on vlan 20 ( on the 24p switch
The 24p switch should be in layer 2 mode, if you have the 48 port l3 switch upstream. Additionally, you need to have the default gateway set on the 24p switch.
We have a static route set on the 24p switch (0.0.0.0 192.168.1.0).
Between the switches, it shouldn't require any static routes, assuming you correctly trunk / tag your ge1 ports, with both switches operating in l3, the ip route table dynamically builds the connected routes, therefore a static route is redundant.

Etherchannel issue between 3750 stack and WS-CBS3012 for IBM blade centre

Hi,
We are trying to configure Etherchannel between four ports of cisco 3750 stack(2ports from one switch of stack and two ports from another switch of same stack). We are facing issues with this setup. The ports in WS-CBS3012 are going to err disable mode.
Is there any limitations associated with such a cross-stack etherchannel configuration. Please suggest if there is any particular sequence of configuration involved.
Switch1 in stack
int gi 3/0/3
switchport mo trunk
switchport trunk allowed vlan 10-30
sw tr en dot1q
channel-group 1 mode on
spanning-tree guard root
switch 2 in stack
int gi 3/0/3
switchport mode trunk
switchport trunk allowed vlan 10-30
sw tr en dot1q
channel-group 1 mode on
spanning-tree guard root
int port-channel 1
switchport mode trunk
switchport trunk allowed vlan 10-30
sw tr en dot1q
channel-group 1 mode on
spanning-tree guard root
in WS-CBS3012 ports are configured with trunk,allowed vlan and etherchannel configuration with mode on.

Hi,
The commnad "no spanning-tree etherchannel guard misconfig" on WS-CBS3012 resolved the issue.

Mutt new tags issue with Gmail via IMAP

Hi all,
I've been using Mutt for a while and I very much like it.
However, Gmail's IMAP implementation is a bit weird and causing me some troubles. I'm accessing my Gmail account directly via Mutt (NO offlineimap and NO trash patch). In particular, I'm getting lots of emails marked as new in my All Mail folder that I've already read.
I've realized that if I receive an email, then read it (or remove the new tag), mark it as deleted and then sync-mailbox, when I go to the All Mails mailbox it's still tagged as new.
If I read the message, sync-mailbox (note this additional sync), mark it as deleted and then sync-mailbox once again, then it doesn't appear marked as new on the All Mails mailbox.
Any clues? This is really driving me crazy. I must be doing something really wrong but I can't figure out what. I've already tried setting delete_untag without luck.
Thanks in advance.
For the record, I'm using Mutt 1.5.20 (with IMAP support but no trash patch). Here's my .muttrc:
set realname = "..."
set from = "..."
set imap_user = $from
set imap_pass = "..."
set folder = imaps://imap.gmail.com/
set spoolfile = +INBOX
set postponed = +[Gmail]/Borradores
set smtp_url = smtp://[email protected]:587/
set smtp_pass = $imap_pass
set copy = no
set certificate_file = ~/.mutt/certificates
set header_cache = ~/.mutt/cache/headers
set message_cachedir = ~/.mutt/cache/bodies
set sort = threads
set sort_aux = reverse-last-date-received
set pager_index_lines = 6
set markers = no
set timeout = 120
set delete = yes
set beep_new = yes
bind index y imap-fetch-mail
macro index pr "<change-folder>=INBOX<enter>"
macro index pe "<change-folder>=[Gmail]/Enviados<enter>"
macro index pb "<change-folder>=[Gmail]/Borradores<enter>"
macro index pt "<change-folder>=[Gmail]/Todos<enter>"
macro index ps "<change-folder>=[Gmail]/Spam<enter>"
macro index pp "<change-folder>=[Gmail]/Papelera<enter>"

I have this same issue using gmail with offlineimap -- because of the multiple tags, removing the INBOX tag (deleting from the inbox) doesn't remove the Unread status from the version stored in the All Mail (or archive) folder. I think we'd need a macro that detected the duplicate mail and marked both as read -- not sure if that'd work or not.
I'd also like to figure out how to tell if an incoming message was automatically tagged with another label by my gmail filter (display what other labels are assigned to a message in any view).
Anyone got any ideas?

Dynamic VLAN assignment issue with ACS & WLC

I have configured an ACS (v4.2) & a WLC 4402 (5.2.193.0) according to the document listed at: http://www.cisco.com/en/US/tech/tk722/tk809/technologies_configuration_example09186a008076317c.shtml
When I attempt to authenticate a user in the ACS local user database, I receive an auth failure. I have enabled debugging in the WLC's CLI and I see that I get an authentication failure from the ACS. Upon reviewing the ACS's 'failed attempts' log, I see the username I attempt to authenticare with but it reports 'CN user unknown' even though this user is the local database.
During troubleshooting, I discovered that if I modify the AAA client for the WLC and change it to 'Cisco Aironet' rather than 'Cisco Airespace', authentication works perfectly, the proper user is authenticated to the local database and I am able to connect to the SSID. The only issue is that because I'm now using Aironet instead of Airespace, the IETF attributes 064, 065, and 081 (VLAN, 802, and the VLAN ID respectively) do not properly assign the VLAN that the user needs to be on.
Am I missing something?

I determined that a NAP was blocking my authentication using Airespace and can successfully authenticate with both Aironet and Airespace now. I also reviewed the debug output of both types of connections and I can see the proper attributes coming through, but the wireless clients just won't assign to the right VLAN interface.
I've reviewed all of the configuration settings per the document about 40 or 50 times now and I am certain I'm not missing anything. I do indeed have override enabled but the configured interface 'management' is still the one the user is assigned to every time, even in the client connection details under the monitor tab. ARGH!!

IEEE 802.1Q-in-Q VLAN Tagging support on Nexus 5548UP ?

Hi,
Is Q-in-Q tunneling supported on the N5K platform ? I can not find any document that says it is.
I am currently running code version 5.1(3)N1(1) and am not able to configure it.
I can however find documents that say it is supported on the N7K platform -->
http://www.cisco.com/en/US/docs/switches/datacenter/sw/5_x/nx-os/interfaces/configuration/guide/if_qinq_tunnel.html
and
http://www.cisco.com/en/US/docs/ios/lanswitch/configuration/guide/lsw_ieee_802.1q.html#wp1049541
If it is not supported on the N5K platform, what are the alternatives on this platform, if any ?
Thx !

Hi,
Curently q-in-q support is not included into nexus 5000 hardware. Nexus 7000 has different hardware base that's why some supported feature list may differ.
HTH,

VN-Tag with Nexus 1000v and Blades

Hi folks,
A while ago there was a discussion on this forum regarding the use of Catalyst 3020/3120 blades switches in conjunction with VN-tag. Specifically, you can't do VN-Tag with that Catalyst blade switch sitting inbetween the Nexus 1000V and the Nexus 5000. I know there's a Blade switch for the IBM blade servers, but will there be a similar version for the HP C-class blades? My guess is NO, since Cisco just kicked HP to the curb. But if that's the case, what are my options? Pass-through switches? (ugh!)

C2504 with LAG and VLAN tagging

Having issues with setting up LAG on a Cisco 2504 WLC and implementing VLAN tagging on the different SSID´s.
Without LAG I had this up and running by using dynamic interfaces and assigning the different SSID´s to a perticular interface which was then assigned a specific VLAN.
However once I enabled LAG on the 2504, the dynamic interfaces became disabled and im unable to find documentation on how to configure VLAN tagging on SSID´s when using LAG.
Relevant info:
Cisco 2504 WLC running 7.4.100.0 (FUS 1.8.0)
Cisco 2602 APs
Cisco 3560 switch running IOS 15 (c3560-ipbasek9-mz.150-2.SE3)
Switch output:
C3560-PoE8#show etherchannel 1 summary
Flags: D - down        P - bundled in port-channel
        I - stand-alone s - suspended

        U - in use      f - failed to allocate aggregator
        M - not in use, minimum links not met
        u - unsuitable for bundling
        w - waiting to be aggregated
        d - default port

                                 Fa0/4(P)
WLC output:
(Cisco Controller) >show lag summary
LAG Enabled
So basically what im trying to achieve is to implement LAG, use 2 SSID´s which are tagged in VLAN 300 and 400 respectively and keep management traffic untagged.

Hi Scott,
Yes I did.. But it seems that after deselecting the "Interface/Interface Group(G)" under the SSID´s and then selecting the dynamic interface again that the problem is resolved.

Is there an issue with Safari in Iphones and Ipads where it does not recognize option disabled="disabled" tag properly?

Greetings everybody,
I have run into a peculiar problem with the Safari browser on mobile platforms (IPad, IPod, IPhone) which I hope I can find a solution for in this community.
I just launched a new website where I sell products with certain variations, for example please view this link: http://www.finerribbon.com/aegean-single-face-satin-ribbon.html
On this particular product, the product variants are supposed to work in such a way where:
If you select the value "1/8" from the "Choose Ribbon Width" field
THEN
The only options active and available to choose from in the "Choose Roll Size" field should be: 500 Yds, 20 Yds & Sample Swatch
Now, if we browse to the above link in Safari using a desktop or a laptop, there are no problems at all, but if we browse to the above link using an IPhone or an Ipad, then we have a problem where all the options are available regardless of the values chosen, basically the above functonality does not work.
I was told that there an issue with Safari in Iphones and Ipads where it does not recognize option disabled="disabled" tag properly, is this true? Can anyone advise me if there is a solution to this problem? I would sincerely apperciate it.
Thank you very much for your time and help!

Issue with HTML tags visible in Outlook emails

Hi everyone, I'm having an issue with a website I'm working on.
On our site, we have a page that generates emails after certain events occur. These are sent to a forwarding address on our mail server, which is then sent to several users on our mail server. These users have their accounts set up in Outlook (one in 2007,
one in Mac 2011).
We're are having an issue where these emails are displaying in Outlook with all of the HTML tags in the email visible. One of the users spoke to Microsoft support, and they remoted in and went through their Outlook settings and were not able to find any issues
there.
This issue is not global exactly. When one of the users added their email to their iPhone, the email displayed correctly. We added a Gmail account and my work account (which I also access through Outlook) to the forwarding list, and it displayed correctly in
both. When we view these emails in the server's webmail client, the emails display fine. The issue seems to be with some discrepancy between Outlook and our email server.
I spoke to our webhost about the issue, and they swore up and down the issue had nothing to do with them, and that it had to be an Outlook issue. I've had several professional web developers analyze the code that creates these emails, and they found nothing
wrong with it. Something that several of my colleagues and our webhost suggested is that the issue could be with the email headers. This is the header for the email, as viewed through Outlook:

Issue with JSTL ( c:import ) tags in Weblogic 9.2

Hi,
I'm trying to migrate a struts (1.2.9) application from Weblogic 8.1 to Weblogic 9.2. This application has JSPs with JSTL (1.0) tags.
I have a JSP page that has multiple (around 7) c:import statements. When I launch my application, only the content from the last c:import statement is being displayed and rest of the c:import tags statements is simply ignored by Weblogic.
I don't find any errors in the logs. When I comment out last c:import statement in this JSP then the content from the above c:import statement is being displayed. Only one (last one) c:import statement's content is being displayed in that whole page.
This app worked just fine Weblogic 8.1.
Any resolutions, hints, insights or workarounds on this issue is appreciated.
Thanks in advance,
Mani

Hello,
You should not need to edit the wlp-light-web-lib.war weblogic.xml file. There are many places where other classes in wlp-light-web-lib are dynamically loading classes (using Class.forName()) from "higher-level" shared library modules (such as wlp-framework-full-web-lib), so I am certain that it works in general. There may just be an issue with how your shared library is set up, or how your webapp deployment descriptors are set up.
So you mention that you have a shared library module containing your implementation of the AnalyticEventHandler; is this a .war file? And in the webapp you are trying to deploy this in, does your weblogic.xml explicitly include your shared library? If so, is your shared library being included before or after the standard WLP shared libraries?
If you would like, posting your webapp's weblogic.xml may help to find the problem.
