Srp521w ethernet sub interfaces on WAN

Hi there,
Have followed the admin guide, and can setup this up fine, however what we're wanting is to turn off any IP connection for the main wan ethernet interface and only have the sub-interface have an IP connection method.
I can't see how you can turn this off, which is causing a double-up of dhcp requests being sent when using both the main/sub ethernet interfaces to use dhcp.
This has been tested on the 521w and 521w-u versions, and I've just used the latest firmware 1.2.4 on the u version.
How can this be configured so that there is only 1 WAN interface that is using IP (the sub interface)
Setting default routes to point to the sub interface doesn't make a difference.
Thanks in advance.
Chaz

Hi Chaz,
Configuring a static IP address on the main interface would be the only way to make it passive. The address to use here could be the same for all routers, as technically it will never be used.
Ensure that you set the interface default route for the WAN interface to the new sub interface.
See the following as an example (I use private 192.168.. addressing in my lab.)
Cheers

Policy maps on port-channel sub-interfaces

We're trying to implement an enterprise QoS policy and I'm wondering how we can apply our QoS policy maps to several different sub-interfaces on a port-channel. In our case, we have both LAN and WAN connections that connect as VLANs on a switch and terminate as sub-interfaces on a port-channel that combines two Gigabit Ethernet interfaces on our router. The LAN connection will need to have a ingress service-policy to classify traffic as it comes from a customer LAN, and the WAN connections will have to have an egress service-policy to place the traffic classes into LLQ and CBWFQ queues as it leaves the router. Could I put both the ingress and egress service-policies on the physical router interface, or should I put them on the port-channel interface? Or should I apply them to the individual sub-interfaces? For example, I could put the ingress classification service-policy on the LAN sub-interface connection.
Any thoughts or insight would be helpful. Thanks.

I can't put it as input because :
gw-a(config-subif)#service-policy input policy_upload
Traffic Shaping feature not supported in input policy.
Here's a show during a bandwidth test. You can see the offered rate is properly measured and is _way_ above the target shape rate.

The difference between IEEE802.1Q Native VLAN sub-interface and Physical interface?

Hello
I think the following topologies are supported for Cisco Routers
And the Physical interface also can be using as Native VLAN interface right?
Topology 1.
R1 Gi0.1 ------ IEEE802.1Q Tunneling L2SW ------ Gi0 R2
R1 - configuration
interface GigabitEthernet0.1
encapsulation dot1Q 1 native
ip address 10.0.0.1 255.255.255.0
Topology 2.
R1 Gi0 ------ IEEE802.1Q Tunneling L2SW ------ Gi0 R2
interface GigabitEthernet0
ip address 10.0.0.1 255.255.255.0
And is it ok to use the physical interface and sub-interface with dynamic routing such as EIGRP or OSPF etc?
R1 Gi 0 ---- Point to Multipoint EIGRP or OSPF ---- Gi0 R2 / R3
Gi 0.20--- Point to Point EIGRP or OSPF --- Gi0.10 R4 (same VLAN-ID)
R1 - configuration
interface GigabitEthernet0
ip address 10.0.0.1 255.255.255.0
interface GigabitEthernet8.20
encapsulation dot1Q 20
ip address 20.0.0.1 255.255.255.0
Any information is very appreciated. but if there is any CCO document please let me know.
Thank you very much and regards,

Hello,
The diagram is helpful.
If I am getting you correctly, you have three routers interconnected by a switch, and you want them to operate in a hub-and-spoke fashion even though the switch is capable of allowing direct communication between any of these routers.
Your first scenario is concerned with all three routers being in the same VLAN, and by using neighbor commands, you force these routers to establish targeted EIGRP adjacencies R1-R2 and R1-R3, with R1 being the hub.
Your second scenario is concerned with creating one VLAN per spoke, having subinterfaces for each spoke VLAN created on R1 as the router, and putting each spoke just in its own VLAN.
Your scenarios are not really concerned with the concept of native VLAN or the way it is configured, to be honest. Whether you use a native VLAN in either of your scenarios, or whether you configure the native VLAN on a subinterface or on the physical interface makes no difference. There is simply no difference to using or not using a native VLAN in any of your scenarios, and there is no difference to the native VLAN configuration being placed on a physical interface or a subinterface. It's as plain as that. Both your scenarios will work.
My personal opinion, though, is that forcing routers on a broadcast multi-access segment such as Ethernet to operate in a hub-and-spoke fashion is somewhat artificial. Why would you want to do this? Both scenarios have drawbacks: in the first scenario, you need to add a neighbor statement for each spoke to the hub, limiting the scalability. In the second scenario, you waste VLANs and IP subnets if there are many spokes. The primary question is, though: why would you want an Ethernet segment to operate as a hub-and-spoke network? Sure, these things are done but they are motivated by specific needs so I would like to know if you have any.
Even if you needed your network to operate in a hub-and-spoke mode, there are more efficient means of achieving that: Cisco switches support so-called protected ports that are prevented from talking to each other. By configuring the switch ports to spokes as protected, you will prevent the spokes from seeing each other. You would not need, then, to configure static neighbors in EIGRP, or to waste VLANs for individual spokes. What you would need to do would be deactivating the split horizon on R1's interface, and using the ip next-hop-self eigrp command on R1 to tweak the next hop information to point to R1 so that the spokes do not attempt to route packets to each other directly but rather route them over R1.
I do not believe I have seen any special CCO documents regarding the use of physical interfaces or subinterfaces for native VLAN or for your scenarios.
Best regards,
Peter

How to make ASR9000 bridge domain forward traffic between sub interfaces of same physical interface?

Hi,
I regularly use bridge domains to connect sub interfaces on different vlans using this sort of configuration:
interface GigabitEthernet0/0/0/5.21 l2transport
description CUSTOMER A WAN
encapsulation dot1q 21
rewrite ingress tag pop 1 symmetric
interface GigabitEthernet0/0/0/10.3122 l2transport
description CUSTOMER A CORE
encapsulation dot1q 3122
rewrite ingress tag pop 1 symmetric
l2vpn
bridge group WANLINKS
bridge-domain CUSTOMERA
   interface GigabitEthernet0/0/0/5.21
   interface GigabitEthernet0/0/0/10.3122
When I try to use the same method to bridge two sub interfaces on the same physical interface so as to create a L2 VPN no data flows:
interface GigabitEthernet0/0/0/5.21 l2transport
description CUSTOMER A WAN
encapsulation dot1q 21
rewrite ingress tag pop 1 symmetric
interface GigabitEthernet0/0/0/5.22 l2transport
description CUSTOMER A WAN2
encapsulation dot1q 22
rewrite ingress tag pop 1 symmetric
l2vpn
bridge group WANLINKS
bridge-domain CUSTOMERA
   interface GigabitEthernet0/0/0/5.21
   interface GigabitEthernet0/0/0/5.22
If I add a BVI interface to the bridge domain then the CE devices at the remote end of the WAN interface can both ping the BVI IP but they remain unable to ping each other.
Is this because tag rewrites are not happening since packets don't leave the physical interface?
How can I work around this and establish a L2 connection between the two subinterfaces?
Thank you

a vlan is usually the equivalent of an l3 subnet, so linking 2 vlans together in the same bridge domain, likely needs to come with some sort of routing (eg a BVI interface).
If these 2 vlans are still in the same subnet, then there is still arp going on, from one host to the other that traverses the bD.
you will need to verify the state of the AC, the forwarding in the BD and see if something gets dropped somewhere and follow the generic packet troubleshooting guides (see support forums for that also).
that might give a hint to what the precise issue in your forwarding is.

Prime 2.0 monitor sub interface

Can you monitor a sub-interface using Prime 2.0 - TenGigabitEthernet4/7.2010? If so how? When we select Design | Management Tools | Port Grouping | Add to Group | Select Group | WAN Interfaces we do not see any sub-interfaces

Step 1 Download the appropriate point patch to a local resource in your environment:
a. With the Cisco Download Software navigator displayed in your browser, select Products > Cloud and Systems Management > Routing and Switching Management > Network Management Solutions > Cisco Prime Infrastructure .
b. Select the version of Cisco Prime Infrastructure that most closely matches the one you are currently using (e.g., Cisco Prime Infrastructure 1.2 ).
c. Click Prime Infrastructure Patches to see the list of available patches for that version of the product.
d. Next to each patch that is required, click Download , then follow the prompts to download the file.
Step 2 Open a command-line interface session with the Prime Infrastructure server (see Connecting Via CLI in the Cisco Prime Infrastructure 2.1 Administrator Guide ).
Step 3 Copy the downloaded patch file to the default local repository. For example:
admin# copy source path /defaultRepo
Where:
source is the downloaded patch file’s location and name (for example: ftp://MyFTPServer/pi_9.3.1.0_update.tar.gz).
path is the complete path to the default local backup repository, defaultRepo.
Step 4 Install the patch:
admin# patch install patchFile defaultRepo
Where patchFile is the name of the patch file you copied to defaultRepo.

Re: sub-interfaces - VLAN - Multiple contexts.

Ok so here is the scenario.
1) create 3 sub-interfaces on a physical interface.
2) create a VLAN and assign the same VLAN to sub-interfaces.
3) create 3 contexts and assign them to sub-interface.
Unfortunately I cannot assign the same VLAN to the 3 sub-interfaces as in step 2).
Therefore I am looking for an alernative solution.
Thanks, gordon

Ok I have some alternative solutions:
VLAN bridging.
seperate VRF.
Use other layer 3 device.
Vmware instance on host server.
Add Ethernet module to ASA.
The most cost effective although not standard is to use the management interface and implement VLAN bridging to overcome the conflict in step 2.

Could I configure local switching between sub-interface and global interface on ASR9k?

Could I configure local switching between sub-interface and global interface on ASR9k?

For 2 interfaces it is probably best to use an xconnect. It is faster and saves system resources (eg mac learning doesnt apply to xconnect).
Config example:
l2vpn
xconnect group link
p2p link
interface Bundle-Ether100.4321
interface Bundle-Ether500.4321
EFP config:
interface Bundle-Ether100.4321 l2transport
encapsulation dot1q 4000
rewrite ingress tag pop 1 symmetric
interface Bundle-Ether500.4321 l2transport
encapsulation dot1q 2000
rewrite ingress tag pop 1 symmetric
This example shows that you can link 2 EFP's with different vlan's together if you'd pop the tags.
If the EFP's are of the same vlan, then popping the tag can be done but not a must. In general it is recommended to always pop vlan tags so there is a standard EFP design, but not for any technical reasons.
When you use a bridge domain and using a BVI, you MUST pop the tags as the BVI has no notion of a vlan tag and wants to see "plain ethernet".

IPSec tunnel on sub-interface on ASA 5510

Hello All,
I working on a security solution using ASA firewall and need some technical advice on ASA. Is it possible to setup a IPSec tunnels on each subinterface of a physical interface on ASA 5510?
I would be greatul if someone please reply post this with some details.
Regards,
Muds

Hi Jennifer,
Thanks very much for your reply. I understand where you coming from, but the reason of using sub-interfaces is that, we have only one physical interface on the firewall connected to the MPLS cloud, and we need to setup a seperate IPSec tunnels for each client for security and integrity. In the current scenario, I have static peers and we can easily setup a static route to peer address.
Many thanks for your assistance, please feel free to to advise if you have any other suggestion.
Regards,
Muds

Asa 5505 sub interface plus ports

I have never used 5505 I gave used higher firewalls and all of them can do sub interfaces normally we make sub interfaces and vlans are assigned to them I m trying to config 5505 can someone tell me how I can create sub interfaces ? As I saw few config and it seems that you config vlans like switch ??? Secondly all interfaces have to b part of vlan ? Ie outside which is g0/0 ....can I config it as normall routed port ?

The 5505 is configured nearly the same a a L3-switch. You configure the Vlan-interfaces and assign these to your switch-ports. The switch ports can be configured as access- or as trunk-ports (if you have a SecPlus license).
You find more on this topic on the Config-Guide:

Can the ASR9K more or less normal balance on uneven number of links?

LMS 4.2 sub-interface not available in the instance selection window creating poller

Hi All,
I have sub-interfaces created on the switch and are in active(up/up) state,but these sub-interface not available for selection in the instance window while creating the poller, and am not able to monitor the traffic on these sub interface in the performance management.

Any Idea..??

How many Standard Ethernet Network Interface by server ?

Hi
Huh... I'd like to install a RAC configuration with 2 server but i've a doubt.
When i list all network interfaces i've:
Server1
en0 Standard Ethernet Network Interface
et0 IEEE 802.3 Ethernet Network Interface
lo0 Loopback Network Interface
Server2
en0 Standard Ethernet Network Interface
et0 IEEE 802.3 Ethernet Network Interface
lo0 Loopback Network Interface
Is it good or not ? (probably not and documentation says that en0 and en1 must be present in the configuration). OK.
I'm under AIX 5.3 and by Smit i've an option intituled "Add a Virtual IP Address Interface". Is it possible to create the second Interface as a Virtual IP adress here ?
Thanks in advance
Regards
Den

Den,
Basically, you would be needing two separate interface cards for each participating node. The first one to connect to the public network and second for the use an interconnect. Not sure, if et0 is really an network interface, if yes, you should be ok.
VIP is nothing but an un-assigned IP address (in the same subnet as your public IP address) which is expected to be inactive before you install the CRS. This should be listed in your /etc/hosts file and/or dns server (if used). Not sure if adding VIP through the SMIT makes it active, if yes, then you might not want to use SMIT to set up the VIP.
This may help you with more information - http://download.oracle.com/docs/cd/B19306_01/install.102/b14201/preaix.htm#sthref378

Issue in Sub-interface traffic on cisco 7609-s router

Hello please support,
I configured sub-interfaces and it is working properly, but some time sub-interface show traffic more then physical interface .
Like
int gi 3/32 0.13 Mbps 12:00 PM
int gi 3/32.11 855 Mbps 12:00 PM
as per my knowledge physical interface have cumulative traffic of all sub-interfaces.
interface GigabitEthernet3/32
no ip address
interface GigabitEthernet3/32.10
encapsulation dot1Q 10
ip address 172.20.128.77 255.255.255.252
ip ospf network point-to-point
ip ospf bfd
bfd interval 50 min_rx 50 multiplier 5
no bfd echo
no cdp enable
interface GigabitEthernet3/32.11

I have not that graph so I am just guessing that you are noticing the difference between policing and shaping. It seems to me you are applying these techniques on each platform on a different way. Try to shape/police in the same order or only to shape.
Hope to help

Sub-interfaces on n5k

Hi, I am trying to connect N5k (layer-3) and ASA, there is a requirement where some of the security-sensitive vlans have their layer-3 on the ASA and for those vlans who are less-sensitive have their svis on the N5k. I am doing a POC in my lab gear first. The n5k and the ASA are connected by 1 physical link having sub-interfaces on both the ends. There is a sub-int with vlan 10 (10.1.1.0/30) on both sides and the ASA injects a default-route to the N5k over this. so in case a non-secure vlan needs to talks to a secure-vlan it goes through via this path. My issue is that, if i create a sub-intf on the ASA, give it a vlan tag of 20, and on my N5k i add a port in that same vlan, i cannot ping my GW (ASA) from the laptop. I have also created a similar sub-int on the N5k side as well with tag 20, BUT still does not work.
attached visio.
Any clues??
Thnx
