802.1Q Tagging Over SONET

Hi there,
I have two Catalyst 6500 switch with sup2/msfc2 with IOS 12.1.20E Enterprise W/VIP and a PA-POS-OC3SMI card on a FlexWAN module.
We have two sites which are connected over OC3-SONET. Both sites have multiple VLANs and inter-VLAN routing.
Is there any way to configure OC3-SONET like a 802.1Q trunk and transmit 802.1q-tagged packets over OC3-SONET.
I thought, I can use Bridging Control Protocol (BCP), but I could not enable BCP on the POS interface.
I appreciate any help.
Thanks

is your sonet private line or some sort of metro ethernet services ? Heres a link to creating an 802.1q tunnel. It might help

Can 802.1q Tag IP instead of Vlan ID ???

Can 802.1q Tag IP instead of Vlan ID ???
Using 3550 and 4507

Hi! William,
Since 802.1q is used only for L2 purposes, it wouldnt be possible tagging IP with it. It is purely used for transferring info about multiple Vlans over a 'trunked' link.
Hope it helped.

Transport dot1q vlan tagging over wan link

Hi,
I would like to transport 802.1Q vlan tagging over a wan link, is it possible ?
I heard about l2tp V3...
Best regards

Hi,
You would have to use a technology such as Ethernet over MPLS (EoMPLS) or VPLS. This technology is referred to as Layer 2 VPNs. You can get more info on this at the following locations:
EoMPLS (part of the Cisco Any Transport over ATM suite):

Configure ce interface to accept all frames (regardless of 802.1q tag)?

On Solaris 9,
is it possible to configure a ce interface so it accepts
all Ethernet frames it receives, regardless of the presence,
absence, or value of an 802.1q tag?
I'm trying to run packet sniffing software on a ce interface
(I'm not using the interface for IP). The Ethernet switch
I'm attached to forwards to me copies of traffic from many
different VLANs, via a port mirroring function. Most of
this traffic is tagged with various 802.1q VLAN tags.
Some of this traffic may be untagged.
My difficulty is that since the Sun Gigaswift 'ce' interface
supports 802.1q, if I configure the interface so it
doesn't "do" VLANs (e.g. 'ifconfig ce5 plumb'), the ce interface
discards any incoming frames that have 802.1q tags.
Alternatively, if I configure the ce interface so it "does"
VLANs (e.g. 'ifconfig ce10005 plumb'), I end up having to
configure dozens of logical ce interfaces (one per VLAN) each
of which will only receive frames tagged for one particular VLAN;
I don't end up with an interface that receives all VLAN frames.
I want one logical interface that receives all the frames,
so I can point my sniffing software at it.
There's no problem doing this with a card that doesn't support
802.1q, since that card will happily accept all frames and pass
them up. So I can do this on qfe or bge interfaces. But I need
to do this using interfaces available on a PCI card
(my V880 has several port mirrors coming from various Ethernet switches),
the interfaces need to be 1000 Mbps (which rules out the qfe card), and
I'd like to stay with copper (which rules out the bge card).
That's why I'm trying to do it with the quad ce card, but I'm
stymied by it support for 802.1q. (If there were just some way
I could turn off 802.1q support for specific ce instances.)
Is there a way I can accomplish this with the
copper Gigaswift interface (Cassini driver) in Solaris 9?
If not, is there another 1000 Mbps copper interface (provided on PCI card)
that can do this?
Or does this become possible in Solaris 10?

Oops, when I wrote "bge" above, I meant "ge", of course.
(ge is fiber gigagbit ethernet interface and doesn't know about 802.1q.)

GigE over SONET

We have a situation where some equipment did not come in and we are trying to bring up a circuit that was going to be GigE over SONET end to end but isn't possible at this time. What we are going to try is to have a 7200 router with a GigE interface and a OC3 POS interface. On the other ende is a SONET Optical switch (Lucent LambdaUnite) with a OC3 and a GigE interface. The Lucent is bridging the ethernet traffic into a VT for of the OC3. This is standard operations there. On the router I was going to set up a bridge group between the GigE and the POS interface, hoping this will accomplish the same thing. Now will the framing of these devices make this totally incompatiable or is there a chance to make the C2 bytes match up or anything. I am guessing the the ethernet traffic will be messed up going into a POS interface when it tries to come out the other end. Thanks for the help.
Jason Smith
www.smif101.com

Hello.
I'm affraid it will not gonna work unless you insert another LambdaUnite to decapsulate the GE from teh SONET stream.
I'm not sure how the LambdaUnite is encapsulating the GE but most probably using GFP/LCAS/VCAT or a proprietary method.
In turn I know that the 7200 doesn't know any of the above mentioned protocol.
Hope this help.

Implementing IEEE 802.1X Standard over wired Ethernet LAN

I'm trying to implement the 802.1X Standard on a wired LAN. Basically it is the EAP authentication mechanisms (like EAP-TLS, PEAP-MSCHAPv2) over the LAN(EAPOL). I've included the EAP Catalog items into my project but found out that the api's exposed by the
eap DLL's are used by RAS. Remote Access service(RAS) I believe uses the Point to Point protocol which is different from EAPOL.
Comparing to wireless, it seems there is a 802.1x Authentication module within the
Native 802.11(Wireless) framework(http://msdn.microsoft.com/en-us/library/gg158436.aspx)
I would just like to know if any Platform\BSP changes or implementations can be made to support EAP Authentications over Wired LAN?
Thank You

Aironet 1100 / 802.3af Power Over Ethernet (POE) Support

I was under the impression that the Aironet 1100 supports 802.3af POE. I purchased a NetGear FS108P POE switch, however, when I plug in the 1100, it does not receive any power.
I have seen references in the documentation to a Cisco inline power injector and a Cisco Catalyst switch that can provide POE to the 1100 and maybe they will work, however, will the 1100 only work with those devices?? If so, it would seem that the 1100 really doesn't support the 802.3af standard and that Cisco's implementation of POE is proprietary.
Any input would be appreciated.
Thanks,
Michael

Hi Michael,
As you have discovered (unfortunately) is that the 1100 only supports Cisco Pre-standard PoE :( Have a look;
Single 802.11g radio offering 54 Mbps of capacity
2.4 GHz integrated diversity dipole antennas
Available in an autonomous version only
16 MB of memory with 8 MB of storage
Operating temperature range of 32 to 104?F (0 to 40?C)
**Inline power support (Cisco pre-standard)**
From this doc;
http://www.cisco.com/en/US/products/hw/wireless/ps4570/prod_brochure0900aecd8035a015.html
The good news is that either of the options you listed will work just fine. I would go for the power injector probably just for neatness sake.
POWERING OPTIONS
The Cisco Aironet 1100 Series can be powered either locally using the AC-DC power adapter, or over the Ethernet cable when coupled with a device capable of delivering in-line power, such as an in-line power-capable Cisco Catalyst? switch, Catalyst in-line power patch panel, or Cisco Aironet Power Injector.
The AC-DC power adapter is included with the access point and can also be ordered as a spare part. The Cisco Aironet Power Injector can either be configured to the order or can be ordered separately.
You can use either;
AIR-PWR-A= Cisco Aironet Power Supply-Input 110-240VAC, Output 48VDC, 380 mA-for 1100 and 1200 Series
AIR-PWRINJ3= Cisco Aironet Power Injector for the 1100 and 1200 Series Access Points

VLAN tags over Pseudowire

I have an existing MPLS Pseudowire connection that I need to rework to be able to carry vlan tags instead of just plain L2 frames.
Existing setup:
ME3400 <-> 7206VXR <-> 7206VXR <-> ME3400
The ME3400's customer facing int tags incoming frames, which go over a trunk interface to a 7206VXR subint. The subint is conf'd for pseudowire p2p to the remote 7206VXR which has an identical setup. Subint on a trunk int to a ME3400, cust facing int tied to a matching vlan.
My thought is use QinQ on the switches, with the question being will the 7206s correctly strip off one vlan tag layer, encapsulate the remaining vlan tagged L2 frame for psuedowire, and on the remote end take the pesuedowire packet, decapsulate it, add on the QinQ tag, and shove it back out to the switch? I won't know ahead of time what vlan tags the customer will be looking to pass, so I need to be able to support whatever they try to throw across this link.

Hi,
You can definitely do that, The pseudowire has 2 labels , the outer label represent the (tunnel label), the inner label represent the (Vc label).
The egress 7206Vxr performs lookup at Vc label and forward the frames un labeled to the ME3400.
On the other hand, with QinQ, the customer vlan access port is tunneled across the Service provider Network, this has no affect in your MPLS Forwarding which done at the vxr7206, The outer vlan tag(tagged by the service provider) is stripped out when the frames forwarded firstly unlabeled to the ME3400 at the egress tunnel interface , the inner vlan tag (customer tag) is forwarded untouched (preserved) to the ingress ME3400 interface.
So, from different point,the MPLS provider is transparent for the Customer Vlan traffic even within the MPLS forwarding LSRs, The Only vlan that is binded to the inner label (Vc label) is the service provider access vlan provided to each customer.

802.1x/PEAP over Ethernet

I am trying to setup 802.1x PEAP in my home lab. I have:
a windows 2003 enterprise server with SP2 and latest patches running as
Active Directory, DHCP, DNS, WINS. The AD domain name is LAB.
The windows 2003 is also running Cisco ACS 4.0.1 with a self-signed
certififcate. I can log into the box https://PEAP8021x:2002 so the cert
works. I also configure the ACS so that it can also use AD accounts for
authentication
Cisco Catalyst 2960 running IOS version flash:c2960-lanbase-mz.122-25.SEE2.bin.
This version supports 802.1x
A couple of WindowsXP with Service Pack 2 and latest patches that will act as
clients for the domain LAB.
Everything is connected to the Catalyst switch 2960 via CAT-5 cables.
I would like to accomplish something very simple. Before user(s) on
WinXP can even access the domain LAB, the winXP machine must be
authenticated with Cisco ACS with username/password on the AD Server
so that the machine can be placed in the correct VLAN(s). If this is just
a visitor and their machine is plugged into my network, authentication will
fail and they will be put in a guest VLAN where the only connection they have
will be acess to the Internet and that will be it. All the information will be pushed
out to the catalyst from the Cisco ACS
Can someone help me out on how to get this done? Thanks.

Hi,
You would need to do following :
- Machine authentication with user authentication( This part is tricky on WinXP, you may get intermittent results)
Something to help you:
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\EAPOL\Parameters\General\Global]
"SupplicantMode"=dword:00000003
"AuthMode"=dword:00000001
- Machine Access Restriction (MAR)(its on ACS)
- guest vlan or auth-fail-vlan

REMOTE RECORDINGS OVER THE WAN IN CCX 7

We have a customer
with CCX 7 local agents and recording services ( BUT NO QUALITY MONITORING)
Normally records all local agents calls ( colocated with CCX.
Now customer has remote agents via WAN and needs to record their conversations.
According specifications and PDI case the sutiationis:
"This deployment model can support silent monitoring and recording for agents at any WAN-connected site by using desktop monitoring. (Refer the Cisco Unified CCX Software and Hardware Compatibility Guide for a list of phones that support desktop monitoring). It can also support SPAN port monitoring for agents on the VLAN segment local to Cisco Unified CCX server. This deployment model does not incorporate additional remote Monitoring components, so silent monitoring and recording is not possible for agents who are using the Cisco IP Phone Agent at remote sites. Similarly, silent monitoring and recording is not possible for agents at remote sites who are using phones that do not support desktop monitoring."
http://www.cisco.com/en/US/docs/voice_ip_comm/cust_contact/contact_center/crs/express_7_0/design/guide/uccx70srnd.pdf
page 4-6
The list of phones not supported for desktop monitoring is listed in the compatibility guide.
http://www.cisco.com/en/US/docs/voice_ip_comm/cust_contact/contact_center/crs/express_compatibility/matrix/crscomtx.pdf
In other words CCX can support "silent monitoring and recording for agents at any WAN-connected site by using desktop monitoring"
But assume you use an IP Phone that supports desktop monitoring
AS RECORDING OPTION WITHOUT QUALITY MONITORING NEEDS MAC ADRESS OF AGENT how can CCX record agent calls taking into accoutn that MAC address is lost when traversing the WAN ...
So the question for this dsicussion is :
IS QUALITY MONITORING THE ONLY WAY TO RECORD REMOTE AGENTS OVER THE WAN OR ARE TEHRE OTHER OPTIONS WITHOUT IT??
Pease reply to [email protected]

It is possible without QM. When using desktop monitoring, the phone is configured to Span to PC port. The agent must be running CAD and the PC running it must be attached to the PC port on the phone. CAD sees the spanned packets from the phone and then forwards them to the recording service on the CCX server. The big gotcha is that the NIC in the PC must not discard 802.1q-tagged packets. If the NIC discards them instead of forwarding them into the NDIS stack, CAD will never see them. Sometimes this takes a Google search and a registry setting change to fix if it doesn't work at first.

Can the AEBS untag a VLAN (802.1q) on the WAN port?

My modem (actually a fibre optical network terminal) provides a DHCP ethernet port. I would like to use my airport extreme for routing and wireless. Normally this would be a very simple setup, except the the modem requires all traffic to go over a specific VLAN (802.1q tagged). So, for this to work I would need the Airport to be able to untag/tag a specific VLAN on its WAN port. Is this possible?

I'll probably try to find the most minimal device that I can get to do transparent untagging of VLAN traffic. Not really sure where I might find that, but will start researching. I'd like to avoid using the current buggy router supplied by my ISP if at all possible!
I would suggest that you look at the various products provided by Cisco. FWIW I use a Cisco RVS4000 as my "main" router and have set up a number of VLANs for my home network with it.

Wireless QoS - DSCP to 802.11e translation

Hi,
Would appreciate some advice, I am using a 5508 controller, I have an SSID that has WMM enabled and platinum QoS profile applied, with default settings. I have 802.11p set to none as we are not doing layer 2 QoS on the switches.
I found that when pinging a wireless client with DSCP set to EF the packets (all packets in fact) are being sent from the AP to the client with 802.11e set to zero. I verified this via AirPCAP.
Can someone confirm why the AP is not taking the DSCP marking from the outer LWAPP IP header and translating it to an 802.11e value?
My best guess is that I need to enable 802.11p on the QoS profile in order for the AP to start translating DSCP to 802.11e. The thing is that I don't particularly want to mark 802.11p as we will not be enabling QoS on the switches, and my understanding is that it's not really required in order for DSCP to be translated from the outer LWAPP IP header to the 802.11e field.
I've reviewed the Cisco documentation on wireless QoS, including the diagram showing the packet flow and copying of QoS markings at each step....
Thanks in advance,
Pete

Hi Pete,
If you are not enable QoS & disable re-write of DSCP on your switches, pretty much you will get the incoming packet DSCP when it leaves any switchport. Therefore WLC should get DSCP EF packets & outer CAPWAP should have DSCP EF. I have done a quick test to simulate your issue. WLAN configured for platinum QoS profile with 802.1p set to none. Wired PC - RTP traffic mark to EF in my case (as windows 7 does not correctly classify traffic).
1. Wired PC (IPCommunicator) ->Switch with no QoS -> AP -> Wireless client (7921 phone)
2. Wired PC (IPCommunicator) ->Switch with no QoS -> AP -> Wireless client (Laptop with IPC)
When I capture traffic for Cisco wireless phone I can see wireless frame is having UP value of "6-Voice". But when I do the testing for wirless laptop client I observed wireless frame are having UP of "0 - Best Effort" (as you observed as well). I would expected in both cases wireless frame UP to be zero. Not sure why behaviour differnt for Cisco 7921 phone.
Then I enabled QoS on the switch & trust DSCP on AP & wired PC connected port & CoS on WLC connected switch port. But left QoS profile 802.1p tag as " None". This time in both scenarios I have observed WMM_UP value "0-Best Effort" in wireless frames even though the AP received outer CAPWAP as EF. This is normal behaviour as QoS profile set to 802.1p to none & therefore outer CAPWAP will not translate to UP=6 as it is. It will cap to max of 802.1p configured (presumed none mean 0)
Finally when I set 802.1p tag to 6 on QoS profile & conduct the same test. I expected in both scenarios UP=6 for EF marked traffic to wireless client (cisco phone or wireless laptop). As expected Cisco phone received wireless frame had UP=6 Voice, but wireless laptop received frame had UP=0 best effort.
I am geussing this due to some kind of WMM incompatibility of different devices (not sure though). I will try to do this with some other clients ( jabber in iPhone & Galaxy SIII) & see any common behaviour.
As per the VoWLAN 4.1 design guide (page 2-18,19) 802.1p classification in QoS profile controll two behaviours
1. Determine what class of service (CoS) value is used for packets initiated from the WLC.
2. Determine the maximum CoS value that can be used by clients connected to that WLAN.
Regarding the QoS profile & traffic mapping, If you set your QoS profile to "Silver with 802.1p Tag of 3" & your wilreless clients' EF marked traffic (ie WMM_UP of 6) will translate into outer CAPWAP DSCP value of AF21 by AP. Same applicable to any video traffic from wireless clients (as it comes with WMM_UP of 4 or 5). But original packet's inner DSCP value remain as it is because of CAPWAP encapsulation from AP -> WLC. Due to this within wired network (at least from AP to WLC) you cannot differentiate Voice , Video packets as all having same DSCP value (AF21). Anyway in your case this won't matter as you do not do any prioratization of your traffic within your switch network.
Just for curiosity why do not you use qos on your switches ? is there any reason ? How do you prioratize your voice traffic over any other type of traffic in your network ?
I am running WLC 4402 with code 7.0.116. What is the software version you are running on your WLC ?
When it comes to software version 7.4 code, cisco introduced "Application Visibilty & Control" feature where you can classify traffic at the WLC as you normally do in wired switches. This will allow reclassify, markdown, drop traffic according to traffic categories.

Native vlans and tagging

Hi all, I know i have mentioned this in the other forum, but i need a bit more clarity.
If I say have a pc plugged into vlan 2, pvid of 2, i gather this means that if ant frame comes in untagged it gets put into vlan 2 right ? ok, well my confusion is what happens to this when it goes over a trunk port, it I put the trunk as member of vlan 1,2,3,etc, will my originally untagged frame that came in and got put into vlan 2 get tagged along the trunk as vlan 2 ?

Hi Carl,
I hope i understand ur question correctly :)
you are asking once farme is tagged with vlan id, what will happen to a frame as it pass through a inter switch trunk port.
then the asnwer is (using 802.1q trunking protocol)-
802.1Q does not actually encapsulate the original frame, it sets the EtherType value in the Ethernet header to Tag Protocol ID (TPID) 0x8100, identifying this frame as an 802.1Q frame. It then inserts an extra two-bytes of Tag Control Information (TCI) after the TPID, followed by another two bytes containing the frame's original EtherType. Together the four bytes of TPID and TCI are called the VLAN Tag.
The format of the TCI is
15:13 12 11:0
user_priority CFI VID
user_priority: a 3-bit field is defined in IEEE 802.1p.
Canonical format indicator (CFI): a 1-bit indicator used for compatibility between Ethernet and Token Ring networks.
VLAN ID (VID): a 12-bit field specifying the VLAN to which the frame belongs. A value of 0 means that the frame doesn't belong to any VLAN; in this case the 802.1Q tag specifies only a priority and is referred to as a priority tag. A value of hex FFF is reserved for implementation use. All other values may be used as VLAN identifiers, allowing up to 4094 VLANs. On bridges, VLAN 1 is often reserved for management.
so ur original vlan tag is retained and other end of trunk port will be able to original vlan id of frame.

802.3ad on ce-1000-4

Is it possible to do 802.3ad on a ce-1000-4 card in a cisco 15454? I have scoured the online information, and i can only find information on how to set up etherchannel or portchannel on catalyst switches and cisco routers. as it is, our entire network from the first piece of equipment past the 15454 and out is all redundant using either vrrp, 802.3ad or some other redundancy (possibly vendor specific). the only point of failure is this card in the cisco. I have messed about alittle in the java interface for the 15454 and i admit im not super familiar with it... but it didnt stick out.
a bit more information, we recently upgraded from a 15454 that supported up to oc-3 to the 10G support model, and with this upgrade came the newest software to that date (about 8 months ago). the port on the ce-1000-4 card is connected to my switch network, and interally using gfp (generic framing protocol) for ethernet over sonet to an oc12 card (i believe mrc) where we have hot standby oc-12 for redundancy. at any rate, this is something i have been fighting with, and slightly worried about for several months, and cannot find the answer. the fight is that the ad links are not only for fault tolerance, but for scalability. we arent in immediate need of more than 1gig aggregate throughput.... but the office is constantly mutating as we add equipment and aquire companies. the ad links make me able to physically move equipment without downtime... locally, but i still have full "internet" downtime when i make the final move off the equipment.
thanks in advance for any help/answers you are able to provide.
eli

If the equipment on each side of the 15454 network that is being connected through the 15454 CE card can run 802.3ad, then you could install a second CE-card in each 15454 and use 1 GE interface from the Ethergroup to CE-card #1 and one GE interface from the Ethergroup to CE-card #2 (tried to diagram below).
Switch #1 -------- GE #1 Etherchannel Group 1 -------- CE card #1 / OC-n ------------- OC-n / CE card #1 ------------- Switch #2
Switch #1 -------- GE #2 Etherchannel Group 1 -------- CE card #2 / OC-n ------------- OC-n / CE card #2 ------------- Switch #2
The 15454 CE circuits would be oblivious to the fact that the network is running Etherchannl as it creates a dumb pipe for the Ethernet link. Depending on your bandwidth requirements, the CE circuits could be carried over a single optical link, like an OC-48 or multiple OC-n circuits, using virtual concatonation (VCAT) supported by the CE card; with the option for protected or unprotected SONET circuits.
The above network would provide protection against a single CE card failure.
I hope this helps!
