Dynamic WDS Discovery over VLAN-Trunk
Hi i have two wds ap each connected to a trunk-port. each has its bvi 1 interface connected to int f0.201 which is mapped to vlan 201. i can access the accesspoint by telnet, but the either do not exchange wlccp information, so everyone ends up as Standalone WDS. If i send updates on f0.201 they exchange wlccp information, but they stock in INIT-Phase. Here my config and the sh wlccp wds:
dot11 vlan-name SVL-WDSC24 vlan 201
interface FastEthernet0
no ip address
no ip route-cache
duplex auto
speed auto
interface FastEthernet0.201
encapsulation dot1Q 201
no ip route-cache
bridge-group 1
no bridge-group 1 source-learning
bridge-group 1 spanning-disabled
interface BVI1
ip address 10.0.201.2 255.255.255.0
no ip route-cache
wlccp wds priority 2 interface f0.201
WDSP57-1U-11-03#sh wlccp wd
MAC: 0013.7f24.36e2, IP-ADDR: - , Priority: 2
Interface FastEthernet0, State: INITIALIZATION
Does anyone have a guess?
thanks, regards dave
Unfortunately the Aironet's Cisco IOS supports BVI interface only on native VLANs.
You have to configure "encapsulation dot1Q 201 native" on the FastEthernet0.201 subinterface and then you should modify coherently the configuration on the switching infrastructure.

Implementing MPLS over VLAN trunk
We are investigation the options of running MPLS between our two core switches (C6509 with dual Sup720s) with the aim of introducing MPLS VPNs. These two core switches are linked via a Layer 2 trunk in a collapsed backbone topology.
Is it possible to create a point-to-point MPLS-enabled link between these switches on a VLAN interface between these switches, rather than an a dedicated physical port? It is anticipated that these two core switches will be PE routers (also acting as RRs, if required).Its possible to run MPLS on any media with IP configurable for it. So till you have IP reachbility on a media, you can run MPLS.
As in your case you can very well run MPLS on an SVI reachable both sides over a trunk.
But as a after thought, why do you want to do this, although its possible, why do you want to carry other vlans on the same trunk which also carrier the internconnect vlan for the PE's.

SG200-08 VLAN-trunk setting ignored after reboot
Hi all,
The ports on my SG200-08 are configured as follows:
Port 1; VLAN 1+4; trunk
Port 2; VLAN 4; access
Port3-8; VLAN 1; access
The config for Port 1 looks as follows: "switchport trunk allowed vlan add 1,4". The problem I want to point out here arises right after rebooting the switch; in the running config, the aforementioned line is now present as "switchport trunk allowed vlan add 4", i.e., VLAN 1 is missing in the trunk. The problem is reproducible every time I reboot the switch. At this moment, I assume it to be a bug in the firmware. This is a problem for me, since the switch's management VLAN is 1 and it gets its IP address (DHCP) over VLAN 1 as well.
I have attached my startup config to this thread, as well as the running config exported right after reboot. In both of them, I've sanitized the rows on user accounts.
Does anyone recognize this problem? Any suggestions on how to fix it?Hi chrebert,
Thanks for your answer. You're right in concluding the VLAN 1 is my default VLAN. The problem is that the switch should contact my DHCP server over VLAN 1 and since the traffic on port 1 is not tagged, the traffic DHCP request will never reach my DHCP server. As a consequence, the switch always ends up with its factory default IP address (192.168.1.254) instead of the IP address assigned by the DHCP server. And yes, that's a problem
So to summarize, when I configure tagged access for VLAN 1 on port 1 and write this to the startup config, it is indeed present in the startup config afterwards. However, the switch ignores this upon reboot, causing VLAN 1 on port 1 to feature untagged access.
By the way, I completely set up the switch from scratch after restoring the config to factory defaults. It would be great if you could try to reproduce the issue and hopefully come with a fix. In case you need more information, please don't hesitate to contact me. -
Is it possible to run a VLAN trunk (DOT1Q) from a Central site to a remote over a MPLS connection?
You can do that either by using dot1q tunnelling or port based EoMPLS. For a description of these two features, please refer to the following document:

I have a packet tracer lab that i am using to learn my CCNA on.
I have 2 sites connected together by layer 3 switches and i cannot ping between the sites.
The trunk is vlan10 with addresses on each side of 1.1.1.1/30 and 1.1.1.2/30
From each switch i can ping the other side.
I have some machines on 192.168.100.0/24 in Vlan 20
and machines on the other switch on 10.0.10.0/25 Vlan 30
From Vlan20 i can ping the local side of Vlan 10 and the same from Vlan 30 but i cant ping over the trunk.
Can anyone give me a hint as to why not?

Fa0/24 1You have no routing protocol running so the L3 switches only know about connected and static routes. The only static route you have is the default:
ip route 0.0.0.0 0.0.0.0 FastEthernet0/24
The interface you tell it to use is a L2 interface, so you're effectively not routing with that default. If you create an SVI (Layer 3 switched virtual interface) for each VLAN on all the switches (i.e. add interfaces for VLAN 20 on switch 1 and VLAN 30 on switch 2), it will work. also if you made the default route on each switch be the other switch's VLAN 10 L3 interface, that would also work.
You could also setup actual routing like OSPF or EIGRP but that's outside the scope for CCNA practice. -
AirPlay discovery over Bluetooth in AppleTV 6.1?
Has anyone got AirPlay discovery over Bluetooth, supposedly added to, AppleTV 6.1, working?
Does it requires an iPhone 5 and/or an AppleTV (3rd generation)?
I'm using an iPhone 4s with iOS 7.1 and an Apple TV (2nd gen) with 6.1:
• AirPlay works fine if I put these two devices on the same Wi-Fi network
But if I switch them to different networks (which are still IP connected though), the Airplay button does not get appear on my iPhone.
• Bluetooth is enabled on both the iPhone and Apple TV 2.
Several sites report AirPlay discovery over Bluetooth working between iOS 7.1 and AppleTV 6.1:
• http://gadgets.ndtv.com/tv/news/apple-tv-61-update-brings-airplay-security-optio n-discovery-over-bluetooth-and-more-494249
• http://forums.macrumors.com/showthread.php?t=1715142
• http://www.iclarified.com/38998/you-can-now-airplay-to-the-apple-tv-in-environme nts-where-bonjour-is-blocked
• https://jamfnation.jamfsoftware.com/discussion.html?id=9969Saito,
• AirPlay mirroring works fine for me when both devices, AppleTV & iOS device, are on the same wireless network.
• We are not trying to do AirPlay mirroring over Bluetooth.
But my institutional network blocks the multicats used by the Bonjour protocol to disocver AirPlay receivers. To use AirPlay here, I must therefor set up an ad-hoc WiFI network and connect both the AppleTV and the iOS device to this network, for the Bonjour protocol to be successful and the AirPlay link to be displayed on the iOS device.
The links I provided suggested that with iOS 7.1 and AppleTV 6.1, one could use bluetooth for discovery of the AirPlay receiver (and hence it's IP address.) The actual AirPlay session would then routed from your iOS device to the IP address of the AppleTV. Bluetooth would not be used for the AirPlay traffic, just for the Bonjour discovery phase.
However, I, like Randall G. Black - TIS, was unable to discover my AppleTV (2nd generation) over Bluetooth. I, like Randall G. Black - TIS, wonder if AirPlay-discovery-over-Bluetooth, in addition to requiring iOS 7.1 and AppleTV 6.1, may have other requirements? Perhaps it only works with the AppleTV (3rd generation)? -
Does the 8540 support VLAN Trunking
I would like to VLAN trunk four VLANs(8540 bridge-groups) from an 8540 switch router to a Cat 5000. I have not seen in Cisco's documentation anything that indicates that the 8540 supports VLAN trunking.
8540 supports both ISL and 802.1q VLAN trunking

Encrypting vlan-trunk traffic between switches
Hi,
Can anyone guide me to some papers or other resources on how to encrypt traffic between 2 switches. The switchces will be connected with fiber and use dot-1q tagging. And I wan't to encrypt all of the trunked traffic.
I was thinking of L2TP, but I haven't found any good description on how to implement this. I have two 3750 switches I thought I might use.
Thanks for any input,

NorwayHi,
Thanks for the response. I had a look at MACsec and it looks good. I would have liked to employ something P2P though, to also limit the ammount of MAC addresses broadcasted on the "wire". But let me first give you an understanding of the task:
We have two sites, connected via fibre and we want to create a VLAN trunk across and order to expand the broadcast domains to te other site.
The IDIOT carrier, has a limitation on the number of MAC addresses they allow on the fibre service, 100.
We also need to encrypt the datatraversing this connectivity.
MACsec wuold work 100% exept the source and dstination MAC addresses are still sent (at least according to https://docs.google.com/viewer?a=v&q=cache:LEf2qOmYZyYJ:www.ieee802.org/1/files/public/docs2011/bn-hutchison-macsec-sample-packets-0511.pdf+&hl=en&gl=za&pid=bl&srcid=ADGEESgmAHXpDOY0RBAE-Rv1HDpu_C_gkeSPN4cv6NGgyP0M1aXVu0UqzCfxo8t_P41ep6J37k4OLKnjfp1M9hoTDHxY22WGz2h7yB7YRLyPvRUbGS8TICzvEMlG92xqbhy6RWFugmnj&sig=AHIEtbTfu0LQIJejdYidE6yzq4lpPifxjQ
And that would cause me to eat into the 100 MAC limit.
Ridiculous I know, but we are looking for an out-of-the-norm plan...

Cisco VLAN Trunking Protocol Vulnerability
I have got a cisco 2821 model router with a c2800nm-advipservicesk9-mz.151-2.T4 IOS, and was reported with 'Cisco VLAN Trunking Protocol Vulnerability'.
Though the device is in server mode, I do not have any domain name or trunk port configured.
Is my device really vulnerable? If yes, whats next?Hi Alex,
for the trunk port on Catalyst on port GE 1/0/45, we need to enable the trunk and for on encapsulation dot1q because this catalyst model is ISL capable also and the SF300 working only with Dot1q Encapsultion
The configuration on catalyst should :
#config terminal
#interface Gi 1/0/45
# switchport encapsulation
#switchport trunk encapsulation dot1q
#switchport mode trunk
#switchport trunk allowed vlan 101-103
#spanning-tree portfast
For SF300 the port trunk it looks fine but for the port where the PC should receive an IP address
#interface fastethernet29
#switchport mode access
#switchport ccess vlan 103
Please let me know after this configuration
Thanks

Decided we'd give the Cisco 300 series switches a try and see
what we think about them compared to our Cisco Catalyst 2960 switches.
I'm already stumped on setting up VLAN trunking between 4 switches. Do I have to manually setup all the VLAN's on each switch? I set them up on the first switch and was expecting GVRP would propagate them to the others like VTP.

How many VLANs supported via MACsec VLAN-trunk link?
Hi,
Any one know how many VLANs maximum allowed across a MACsec link between two C6500 with Sup2Ts or between two N7K respectively?
As far as I know, C3750X has limitation of 8 VLANs, according to
•Cisco TrustSec enforcement is supported only on up to eight VLANs on a VLAN-trunk link. If there are more than eight VLANs configured on a VLAN-trunk link and Cisco TrustSec enforcement is enabled on those VLANs, the switch ports on those VLAN-trunk links will be error-disabled.

WRVS4400N VLAN trunking question
Hi all,
I just got a SRW224G4 today my main objective is to trunk 30 VLAN(s) to my WRVS4400N for interVLAN communication. So far I set G1 on my SRW as a trunk port and linked it to port 2 on my WRVS4400N (which is also set as a trunk).
So far no good when I go into LAN settings I do not see an option wheree I can set DHCP addresses or gateways for these VLAN(s). Is this even possible with the WRVS4400N I meen if Linksys is going to provide a small business solution atleast their equipment should support VLAN trunking with each other.
If anybody knows the solution to this please let me know.
CheersFrom what I know, although the WRVS4400N has support for port based VLAN setup, it does not give you the option to set different DHCP addresses for each of the 4 VLANS.

I found this site too which shows how to configure it: http://lachlanmiskin.com/blog/2012/08/01/cisco-sg-200-08-trunking/
Cisco's datasheet says it supports tagging 802.1q.

VLAN trunking newbie SRW208MP to SRW2008MP
Hello All,
Just need a simple setup - 2 VLANs, a few ports each, on each unit, trunked together (ultimately on SFP module). Tried what seems to be right but (natch) not working. Just need simple guidelines to see where am going wrong. Thanks!OK, well, using that example, as well as another thread here (Cisco SLM224P
VLAN TRUNKING), I reset and redid all the VLAN related settings.
There are 2 subnets in play here -
10.51.0.0/255.255.252.0 - VLAN 1 - Used as the Management VLAN.
10.51.4.0/255.255.255.0 - VLAN 5 - A subnet for Wireless LAN POE connection and management.
And 2 switches -
198 is a SRW208MP, remote unit. will have single WAP and various devices.
199 is a SRW2008MP, at head end near subnet(s) source. Will have up to 4 WAPs and the
connections required to provide for both subnets.
For purposes of discussion, the planned fiber SFP interconnect is being played by a copper trunk.
Setups follow:
198 VLANs-
198 Port Setting-
198 Ports to VLAN 1-
198 Ports to VLAN 5-
198 VLAN to Ports-
Unit 2 - 199
199 VLANs-
199 Port Settings-
199 Ports to VLAN 1-
199 Ports to VLAN 5-
199 VLAN to Ports-
The configuration as posted does not provide the expected results.
I am convinced I am overlooking something simple. Usually is!
The net results are that the Management VLAN (1) is present and accounted for on both switches, but that could even be because they are acting as switches do.
The VLAN 5, however, does not function at either end. The 'Local' switch, 199, shows traffic on the WAP ports but no traffic of any consequence is traversing and the WAPs are nonresponsive.
Ditto Remote switch. Management VLAN yes, 5 VLAN no.
Any suggestions greatly appreciated. -

interface GigabitEthernet1/0/24
switchport trunk native vlan 10
switchport trunk allowed vlan 10,20,30,40
switchport mode trunk
end
But my AP doesn't seem the get an IP. Where as if I plug it in on Switch 1 it does with the same settings.
So I am assuming there is something wrong with my trunk. What am I doing wrong?
Thank you,
MichaelHere are a couple of observations:
1. The switchport trunk encap dot1q command was not applied on the 2960 because 802.1q trunking is the default. The 2960 series switches do not support ISL encapsulation, as the OP observed. There is, therefore, no need to manually specify the trunking protocol. The show int g1/0/24 switchport command confirmed that trunking is working. I find the show int g1/0/24 trunk command to be more informative in this context. It tells you what VLANs are active and trunking between the connection.
2. You do need to define VLANS 2-30 on your second switch. You can do so manually or you can configure VLAN Trunking Protocol (VTP). VTP is your easiest bet. Example config:
Switch 1
sw1(config)# vtp mode server
sw1(config)# vtp version 2
sw1(config)# vtp domain MY_DOMAIN
sw1(config)# vtp password MySecret
Issue a show vtp status in priv exce mode to very your settings.
Switch 2
sw2# show vtp status
Do this command FIRST and make sure that the configuration revision number is smaller than the revision number of SW1.
VTP Operating Mode : Client
Maximum VLANs supported locally : 255
Number of existing VLANs : 25
Configuration Revision : 174
If config revision on SW2 is greater than config revision of SW1, then issue following command:
SW2(config)# vtp domain bogus
SW2(config)# vtp domain MY_Domain
SW2(config)# do show vtp status
Your config revision should go back to zero.
Now issue the same commands on SW2.
SW2(config)# vtp version 2 (pretty sure that is default, but I issue it anyway)
SW2(config)# vtp mode client (means you cannot define VLANs on this switch. Most admins prefer that only one switch be capable of creating VLANs).
SW2(config)# do sh vtp status
The config revision was important because injecting a switch into your network that has a higher VTP revision can overwrite your existing VLAN database. If that happens, chances are that most of your network traffic will cease to function as all of your access ports will be in a VLAN mismatch mode.
