Cisco Firewall :: Bandwidth Allocation On ASA 5510
Nov 8, 2012
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.

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.

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 Cisco 2851 router & need to allocate bandwith based on IP's. eg. 192.168.1.1 should use 7 Mbps & 192.168.1.2 should use 2 Mbps & 192.168.1.3 should use 1 Mbps. Let me know the configuration on how to execute it on a router.

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 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?

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 a 20/20 MB circuit and an ASA 5510 and I am able to setup policing were the interace gets 512k down and 128k up so when I conduct a speed test with one user I get 512k and 128k and when I conduct a speed test with two users each gets 256k and 64k. [code] What I want to happen is that each user gets 512k and 128k until a saturation point is hit and then I want the ASA to slow all users down equally.

I'm working in my lab trying to do proof of concept for traffic policing on the ASA 5510 running 8.0(4). I have two laptops running Ubuntu one on the outside and one on the inside. Both laptops have 100Mbps interfaces. My tests consists of downloading a file from one laptop using HTTP. Without any QoS I can see speeds close to 100Mbps which I would expect. On a side note, try using XP and you won't come close to those speeds. Anyhow, I implement policing using the config below and expect to see the max rate on the laptops during the transfer max out close to the CIR. However, I see speeds much higher on the laptops.
When I set the CIR to 10000 bps with bc at 1500 bytes I get speeds that range from 300Kbps to 700Kbps. I would expect to see speeds max out at the CIR which would be 10Kbps.I'm having a hard time understanding why my numbers don't match.

I have some clarifications regarding ASA firewall, it can be support bandwidth management and content security at the same time. we are looking for below features in ASA5510.
IP/Policy based bandwidth management.Controll the bandwidth and allocate the bandwidth to specified users or servers.Content Security. If not, which device I need to set for Internet Bandwidth Management and content security.

In ASA 5510. How I can limit the users in (VLAN 20) to use the internet with a limited Bandwidth/speed with 3 mbps upload and 5 mbps download?
In case the outside interface (Native vlan) which is connected to the ISP and have a bandwidth/speed of 30 mbps upload and 50 mbps download.

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?

We have an ISP connection that is connected via an ethernet interface on a 5510 ASA. We are allotted 10Mbps. I have currently have the interface set to 10Mbps Full. However we want to upgrade the connection to 25Mbps. I know I can set the port speed to 100Mbps and then set a shape/police statement and shape down to 25Mbps.
Management wants to be able to call the ISP and arbitrarily adjust that speed up temporarily at any time without any user/admin intervention on our side. I can simply leave the port at 100Mbps i.e. no shape statement on my side however I will run into problems with large amounts drops, overruns, retransmissions, etc due to the ISP shaping the connection speed during normal operations. However they then could then adjust the speed at any time without needing me.
I do not know the best way to make this work. Is there some sort of dynamic/smart shaper in the ASA or another cisco device?

We have a Service Policy rule setup on our 5510 for SMTP traffic.
Problem is, this week someone sent a larger email 20+mb to dozens of recipeints and the outside interface was hitting 10mb, which is not what I would have expected with this rule in place, so I'm questioning the configuration. We know it was email because I disabled the server that receices our outbound mail to apply a signature and the traffic dropped immediately.

I matched the traffic statistics on one of my Cisco ASA site-site tunnels with the OID:1.3.6.1.4.1.9.9.171.1.4.3.1.1.25.4142 (cipSecTunHistInOctets). I was real proud of myself for a few days until I checked the history and found the OID wasnt working.After some troubleshooting I found that the last four digits (4142 in this case) change whenever the tunnel drops and re-establishes itself. Any way to collect tunnel utilization history on an ASA with SNMP? Is there a different OID I can use thats based on the endpoint IP?

Recently i had a requirement for implementing a Qos on one of my Mpls link which is of 2Mbps, the requirement was to allocate a bandwidth of 512kbps for each connect that comes in and 512 kbps for out going, and it is in ASA 5510 firewall.
So i have done the configuration successfully, now the issue is, the bandwidth is limited to 512kbps only for all the connection,how many may be the connections, it working below 512kbps,
But my requriemt was for the first connection, it should allocate 512kbps , and for the second another 512kbps so on.its not happening, the bandwith got struckup at 512kbps , all the connection are sharing this bandwidth only.

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.

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.

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.

I'm using a Catlyst 3550 to supply power to a IP network surveliance camera. By default, the predecesor to POE, Cisco Inline Power allocates 15.4 W of power to a port ... What is the process for reducing this power output?
"For an IEEE device, the switch always allocates 15.4 W to the port. The switch does not display the IEEE class type in the show power inline privileged EXEC command output. Instead, it displays n/a."

Were running an ASA5510 with multiple IPSEC VPN clients over a 100Mb leased line. At the moment we have about 10 active clients however we are looking at gearing up to about 100 clients.Question is, is there a known method for calculating the required bandwidth for this number of clients or indeed obtaining metrics from already connected clients with this calculation. We have tried a few monitoring products, most notably Solar winds, however none of the products we have tried seems to be able to give us the throughput of the individual VPN connections to assist with our calcs....

We have a Cisco 881 router, which is crashing. We have seen that the ARP cache fills up so much it causes things to crash, our phones go down.. We dont know why this however IP CEF seems to be doing it, when we disable it goes away however disabling IP CEF causes our L2TP tunnel to become inoperable also. So why does IP CEF cause thousands of AR entries and how can we limit that!? Below is the error, sample of the ARP cache and our config. You will notice we also have a /31 given to us on WAN interface, this was given to us by our service provider. This is really strange I cant find other examples on internet.
The error:
Nov 1 04:21:57.474: %SYS-2-MALLOCFAIL: Memory allocation of 65536 bytes failed from 0x81F083F4, alignment 16
Pool: Processor Free: 55176 Cause: Not enough free memory

I have a tale of woe for you who may be considering Hybrid REAP with local switching.
My client has a varied configuration, but the requirements basically screamed HREAP with local switching. They have 15 sites, had already purchased a single WLC 4404 and they needed between 4 and 24 APs at each of the sites. Each of these locations are connected by a WAN link of good quality, but only a single link so there is no assurance of availability; the client has local resources so it would be useful if wireless stayed working during an outage.
So I setup the WLC for HREAP local switching. I setup AP Groups VLANs, but I noticed it had no effect on the VLAN allocation for HREAP. This was unfortunate, because not every site has the same VLAN configuration - some sites had a L3 switch and others only a L2 switch. But I suffered through this and configured each AP manually with the appropriate VLAN mappings.
The infuriating thing, is now that they have bought a second WLC 4404 (they expect to increase the number of APs beyond 100) all these VLAN mappings are messed up when APs connect to the second WLC. I've been going through them one by one again - it is really unfortunate that the AP Groups VLAN mappings don't apply to HREAP local switching.
I'm going to get back to the next 80 APs - but if some of you have a system for handling the VLAN mappings of a large number of APs.
