Bandwidth Allocation To Vpn Interface Under Physical Eth0?
Feb 15, 2012
I have my wan connection on the eth0. The bandwidth is 2mbps. I am running qos on that interface saying 192.168.200.0/24 can use 80% of the bandwidth and 192.168.201.0/24 can use 20% of the bandwidth. I Also have vtun VPN inteface to our branch office. I also wan to run some qos on that interface. How do i go about allocating the bandwidth on this interface? it is actually going via the eth0 interface, but the system actually see's it a an independent interface on its own right, so it requires it's own qos policy.

I'm having trouble getting my Ubuntu 10.04 machine (Sony Vaio VGN-SR490) to connect to the Internet by way of an Ethernet cable connected directly to my router.
I'm able to connect to the Internet using this same cable using a Windows machine, way Linux is configured. [code] It looks like the network adapters list is empty. I will now install both Windows XP and Ubuntu Linux dual-boot. I'm still not able to access the internet, even through Windows. I'm wonder if this could be a hardware problem with the computer or a problem with the router itself. Other computers can connect to this same router, and work fine.

Here are my network settings on Linux:

I am trying to find out wether it is possible to allocate bandwidth on a per-vlan basis.
We have multiple satellite connections coming into our infrastructure over a single gig ethernet cable from another service provider. The provider provides the connectivity on layer 2 and we are responsible for layer 3 connectivity for the clients on the other side of the satellite connections. The single gig ethernet cable is currently plugging into a Mikrotik 1100 router on our side, setup with VLAN ID and IP Addresses and everything works perfectly. The challenge now is that whilst we only have the one satellite client connecting, we can limit the bandwidth on the ethernet port to 512k for example which limits the client to only have 512k internet breakout. In the future, we need to be able to limit bandwidth as multiple VLAN IDs will be coming over that single ethernet cable and I'm not sure if one can do this at all.

I have an internet connection (landline and wifi modem) at my parent's summerhouse as I need it for work. Nobody else does around here so I get constant nagging from neighbours to give them the password. I can't say no however I'm afraid they may use up too much of my bandwith connection which could lead to alot of money being lost from my part. Constant and stable internet is a must for my work. how can I limit the bandwith I give to them? Can I create a second public network with limited bandwith or something like that?

We have a DSL line at work which a few people share for Internet access.Sometimes if someone is doing a Windows Update or big download etc, the connection is maxed out and slow for everyone else.Is there a way to give everyone a set amount of bandwidth via a Cisco router (2811) or will I need to use something like a packeteer?

I have a cisco ASA firewall 5510.Just i have configurd for 1st port as nameif ouside witch public ip, 2nd port as a nameif inside with local ip, and done the nating, dhcp and dns. now i am able to get internet from inside port, which is getting dhcp.up to that it is ok.
And I want to restrict bandwidh 1Mbps for local port (2nd port) how to config 1Mbps banwidth allocation for port no 2, I mean nameif inside should have 1Mbps limet.

limit the bandwidth used by certain wireless devices on my network. The problem I'm having is of priority. For some reason when someone is watching Netflix on my laptop (wireless) no other device has any bandwith available to it, so while someone is watching Netflix my hard wired desktop can barely load Google.com much less do anything useful.I'm using a Cisco ValetPlus M20 wireless N router.allocating at least a minimum amount of bandwidth to wired devices?

I have five 877 routers connected to ADSL circuits provided by Vodafone. Each has a VPN tunnel back to a PIX.
Occasionally one of the sites will lose it's connection to the PIX.
When we check the log, we find entries like these:-
Apr 5 01:31:54.085 UTC: %LINEPROTO-5-UPDOWN: Line protocol on Interface Virtual-Access2, changed state to downApr 5 01:33:19.344 UTC: %CRYPTO-
[Code].....
As you can see, the physical interface (ATM0) is not being reported as changing state to down, neither is the Dialer interface.
When the router is in this state we have to SSL to the public IP address of it and manually restart the ISAKMP SA.
When the router sees the ATM interface go down and subsequently come back up, the VPN connection to the PIX also recovers.
So - in a long winded way I think I'm asking....why does the Virtual interface go down and is there anything I can do to stop it happening?

I have a network with Two 3800 Cisco Routers as Central and many Cisco 2811 Router as Branches. Now I set two Tunnel on each router connection Interface FastEthernet from each 2811 to SubInterface Fastethernet on 3800. I set OSPF as Routing Protocol and I configure QOS on Tunnel connections. Then I have a safe connection with backup connection between 3800 Router and each 2811 Router. Now I want to set VPN with IPSEC and Certification Authentication with CA Server for Security all connection. I set IPSEC and ISAKMP and Certificate on each Router and Set Dynamic VPN on Cisco 3800 Router and Static VPN on each Cisco 2811 Router. Now when if I configure tunnel with Crypto map, it works correct and all packets are encrypt. But if I try to set crypto on physical Interface(because I want to set qos on tunnel then protect packets on physical interface) however all packets are routed but crypto and encrypt d o not work. Set qos on tunnels and crypto on fastethernet interface.

I am preparing configuration (currently in lab) for Per-Tunnel QoS in DMVPN on ASR 1002F for one of our customers, and I came across one issue. According to restrictions for this feature, I cannot apply per-tunnel QoS in conjunction with interface based QoS. This means, I can provide shaping with hierarchical CBWFQ for each spoke, but I cannot guarantee anything on physical interface! What if there are services in native MPLS? I am also unable give reservations for BGP which is used on PE-CE link! How about monitoring spoke PE-CE links natively? I can only apply policy-map with class-default on physical interface. When I add anything related to queuing for that class (or any other non-default class) I get the message:
R1(config- pmap)class routing
R1(config- pmap-c)#bandwidth 16
service-policy with queuing features on sessions is not allowed in conjunction with interface based

We have to enable FIPS 140-2 on our ASA5520's for all our IPSEC VPN connections. We currently have failover on our 5520's. I found a lot of information out there but some seems to conflict one another.What are the things I need to look out for - caveats? Does the clients that connect to the VPN had to use different clients once the FIPS was enabled.Do we need to recreate logical interfaces for each physical interface we have?

What are the pros and cons of configuring a Switch Virtual Interface (SVI) versus a routed physical port between layer 3 switches?For example, if I have two 4506s and have a need to run HSRP and route between them which feature is better and why?
switch_a
!
interface vlan 25
ip address 10.10.10.1 255.255.255.0
!
interface fa0/1

how to configure this. I did it in the past but kind of forgot how I did it.I have a stacked 3750 (two physical switches) connecting to a 2960.
I am creating trunk ports with limited access to VLAN 300, 600, and 700.
There is two interfaces connected from the 3750's(one on each physical stack member) to the 2960.I have the physical interfaces configured exactly the same.
3750 Config:
interface Port-channel2
!
interface FastEthernet1/0/46
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 1, 300,600,700
switchport mode trunk
speed 100
[code]....
Should I keep the configuration on the physical ports and not configure the Port-Channel Interfaces? Do I need to configure port-channel load balancing? Is the channel-group mode sufficient? Goal is to basically create 2 links to the 2960 to double the bandwidth and provide redundancy.

On the ATM0 interface on a 877 do you have to configure the bandwidth or will the router automatically negotiate this ? Also is the bandwidth command in relation to the upstream or downstream bandwidth?. We currently specify bandwidth 448 which matches the upstream.

I have a requirement where 3 Branch locations of an organization is connected to their hub location via MPLS.They have an internet connection only at HUB as shown in the diagram (Attached)Now all spoke locations should access internet via hub.At spoke locations is there a way that I can have Cisco 2900 router and dedicate only 30% of the WAN bandwidth for internet browsing traffic.Remaining 70% should be used for accessing applications at hub.
For example if i have 5 Mbps Mpls port at spoke I want to dedicate only 1 Mbps for internet browsing traffic remaining should be dedicated for accessing the application at hub.How can we acheive this? Can it be done by using PBR and rate limiting?

We have a new 100MB internet service, but we only pay for 10MB and above that is a per/MB fee and not cheap. I want to limit all traffic inbound and outbound only to use up to 10MB on the outside interface of our Cisco 3825.

Is there a way I can find out the amount of bandwidth i'm using on a particular interface on a 4507 cisco multi-layer switch? It is a gig port and I have it setup for monitoring (spanning) and I see packets being dropped in the "Total Output Drops" area. To me it looks like it must be exceeding the 1gig limit but I don't know a way to check to make sure. I also have the queueing strategy set to FIFO.

CBWFQ kicks in when the interface becomes congested and there is no available space in the queue but I need to find a solution to the scenario below:Im using a Gigabit interface on the 3945 Router that connects to the ISP. The ISP limits bandwidth to 60Mb so I need to make sure when I reach the limit of the 60Mb the router starts using the BW percentages defined in the policy-map using classes. any kind of traffic go out as it wants but as soon as the 60Mb limit is reached, the priorities defined by the traffic classes will kick in just as if the interface ran out of queues (as CBWFQ usually works).

The other day 3rd party supplier ran some stats on our Gigabit link between 2 Cisco catalyst 3750Gs.now the graphs produced showed only a Maximum output of about 100Mbps ( 5 minute intervals) yet when I do a show interface it shows a lot more always 150Mbps and more. So I did my own Perl script doing an "sh interface" every minute and then graphed it, and the results were a lot different to the MRTG results.Questions: I know MRTG uses SNMP to get the traffic is there a bug in the SNMP, what OID does it use?does the "sh interface" give the correct results?

Starting a project where they customer has ASA 5585X with SSP40 with 10K SSL Premium Lic and ACS5.1.The cust wants IPSec, and Anyconnect Client terminations. The number of users will be close to 6000 and will scale.Due to the huge scale of users, i am not able to finalize a design. Have the following doubts.
1. Will ACS have any issues in supporting a database this huge. OR is it better to go with the AD/LDAP integration.
2. What is the best way to allocation IP address. Does ACS 5.1 support dynamic allocation form an IP pool.
I have been browsing through the forum, couldnt find anything concrete.

We have a WLC 5500 connected to a 2960 acting as core switch. there is a server attached to the switch , bearing all dhcp pools for lan and wireless users. Can the wlc or the switch be configured in such a way that the wireless users associating to the wlc get their ip addresses from the dhcp pool configured on the server. Can the configuration can be shared for such a setup.

I am using a Pix515E with 8.0(3) and 128MB RAM. It ran OK for months but has recently had several episodes during which it produced streams of memory allocation failures (syslog 211001). When in this condition I could not log into the VPN. It was still operating but some users were having problems and I eventually had to restart it.
The traffic load is typically 10Mbps, and the max number of connections is around 10,000 but typically 5,000. The CPU usage is 10%-20%. There is 1 VPN with normally 1 client. The memory usage is always high, between 115MB and 120MB but during these problems it creeps higher.
Why might the memory usage be so high when my network load is quite light for the 515E? What circumstances cause the memory usage to increase during operation? Is there anything I can do to prevent the memory usage increasing to the point where the PIX crashes?
I have a second 515E with 8.0(4)32 and 64MB RAM, loaded with the same config. I have not had this one in service, but off-line it is using 53MB of memory. If the spare pix needs 53MB to load the firmware and my config, why does the other one use 115MB?

using ACS 4.2 and I can't find a way to bind an incoming NAS port to a specifc IP Pool:
When a user connects the request to auth comes from 2 possible NAS ports randomly (this cannot change). Depending on which NAS makes the requests determines the IP range required, so I need 2 IP Pools. There is no way to say 'if request comes from NAS1 give IP from Pool1 and if request comes from NAS2 give IP from Pool2'
I have gone around and around with NAFs and NARs, but cannot do this.I can create 2 ACS groups with the specific NAS and specific IP pool within, but then I cannot have a single username bound to both groups.
I moved the auth to an AD group in the hope that I could bind that single AD group to the 2 ACS groups; and so have a single username, but no joy.
