Cisco Switching/Routing :: 3945 / Using CBWFQ Before Reaching Interface Max Bandwidth
Jan 11, 2012
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).

I recently upgraded to the 107Mbps service from sudden link. The tech tested my signal coming into the house and it proved to be very strong. I then hooked up the Motorola Surboard Docsis 3.0 modem via hardline to my iMAC and my brother's PC running 7. He and I both did the speed test and we are only getting 50-75 Mbps. The tech claimed we needed to wait and the speed would build up, but its been 24 hours and still around the 50-75 range. We also got higher rated cables to ensure that there was no loss. I made sure the settings in the modem was set to send out 107Mbps and the Tech agreed that the modem was capable of delivering the speed. Both my brother's PC and my iMac are within 3 to 4 months old. The modem is also about 6 months old. why the speed is not clocking at or near 100Mbps.

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.

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?

i have 7206VXR with trunk interface toward customers, now i'm trying to configure CBWFQ on one of the sub-interfaces for specific customer,while trying to apply parent policy which includes child policy i'm getting the following message:Must remove traffic-shape configuration first.
here is the configured policy:
ip access-list extended ACL_TEST_SRV
permit ip any host 192.168.10.1
permit ip host 192.168.10.1 any

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

I have a 3945 router with two interfaces connected to my firewall, one to the management interface and another to my dmz. I'm running eigrp between all my network devices. The problem I'm running into is when I try to ssh to the management interface of the 3945 the traffice hits the firewall, then goes right to the management interface as it should, but the return traffic is trying to use the dmz interface since that is how the router knows to get back to my computers network. I created 2 route-maps to try and address this issue. [code] I've applied the MANAGE_IN route-map to all interfaces that might have inbound traffic destined for the management network and applied the MANAGE_OUT route-map to the management interface. The MANAGE_IN policy appears to be functioning correctly, the MANAGE_OUT doesn't appear to be functioning correctly. When I look at traffic from my host going to the management interface I see it still trying to return through the dmz interface.

I currently have a Cisco 3945 router deployed and I am reaching the CPU's max during peak usage. The 3945 supports ~500Mbps Fast/CEF Switching and I need something at least double that capacity.
I need the ability to have at least 8 RJ-45 10/100/1000 connections. I also need the ability to NAT.

We are having problems with a two router 3945 in HSRP and a switch 2960.The two routers are connected to the switch 2960 through differentes ports. The problem is that we loose connection between the router and the switch.When we excute the command: show cdp neighbor at router, it shows nothing.If we try to make ping to the 2960 switch it is no reachable.If we make ping to the other router 3945 it is not reachable.All other function of the router are o.k.We are attaching the IOS of the routers and switch 2960 and a document in which make reference to a BUG in which mention about arp overwrite due arp attack which produce DoS.

I am using DHCP/TFTP to autoconfigure a 3945 router. The router properly obtains an IP address and finds the correct TFTP server. The issue lies in the download of the configuration file from the TFTP server. The router downloads the file, gives the "Ok" message, and prompts you to press Return to get started. When I view the running-config, several commands are missing from the Serial 0/0/0 section (HWIC-2T). If I modify the config file on the TFTP server to use Serial 0/0/1 instead and repeat the process, the configuration file loads without any issues and Serial 0/0/1 has all of the commands.
I also tried moving syntax around in my config file, but the end result is still the same. If I use Serial0/0/0 - I don't get all of the commands. If I use Serial 0/0/1, I do.

connecting a Cisco 3945 Router to an Ethernet WAN Link. The service provider has provided a 100M Ethernet Single Mode Fiber handoff to the customer premises with SC Connector. The CPE configuration proposed for this setup is like this. [code]
Since the SFP has LC Connector, i suppose i need to have an SC-LC Cable for connecting the Ethernet link. Do i need anything else, apart from above?

I have a Cisco ASA 5505 and I have my internal and external interfaces configured but I currently cannot ping from the inside to an IP Address on the outside. I had this setup and working and I have another set of equirement that I am replacing that is working with my service provider so I know it is a configuration issue. When I ping 4.2.2.2 for example I get:
Destination host unreachable
Do I need to add a static route from my inside interface to my outside interfaces?

I am getting ready to deploy a 3945 ISR to serve as an internet and core router for and remote site. I will be terminating a site-to-site VPN tunnel on it and also configuring a zone based firewall config between my "outside" (internet link) and "inside" (all internal nets). My question is about how to approach securing the WAN interface with the Zone based FW in place?what kind of ACL do I need beyond those allowing and restricting remote access to the outside ip?

I would like to connect to a 1Gb routed uplink, and then impose bandwidth limits (via shaping/policing/whatever) on a per port basis. The ports could either be configured to route, or as switchports on separate VLANS. I'm trying to identify hardware that will let me do this. The set up I have in mind is shown below.
I am wondering if the IP Services Adv software on that switch will allow that functionality?

I have a 4500 and 6500 that I'd like to be able to limit the bandwidth of layer 2 switchports. So for instance I have all GB blades but certain servers I'd like only to have connections of about 5 Mb per second or 15 Mb per second etc.

They have a /28 wan adress coming from ISP, that gives out 100Mbps, going to a Cisco 2960S switch (ver. 12.2) the switch is only holding 1 vlan. Connected to the 2960 are 3 firewalls/routers from other manifactors, each creating their own network. The customer wishes for a solution where each final FW/router gets minimum 33% and maximum 100% of the bandwidth, depending on how much each final Fw/router are in use.

The layout of the equipments are as such,other equipment <--> 2911 Router <--> Ether-Switch/3925 Router <--> 7206 <--> Internet,During certain times at night, the 2911 exhibits cpu load, high packet loss and an increase in bandwidth of at least twice it's normal amount. this results in packet loss in all the other equipment. I am attempting to locate who was demanding such a high burst but so far the graphs display normal rates for all the other equipment.Because the 2911 demands an increase from the 7206, the 7206 is able to accommodate this as it still has balance BUT my other equipment that are connected to the 7206 takes a drop in bandwidth as well. the graph shows that when the 7206 bursts higher, the rest of my other links take a slight drop in bandwidth.Also, the graph from Ether-switch to 2911 indicates the bandwidth hike BUT the graph from 2911 to ether-switch does not display the same thing as due to the cpu load, the data is somehow not captured properly.

I have a 2900 router at branch office. This router has a 4 port switch card and two gigabyte ports. The gigabyte port is use for wan connection and the 4 port switch card is use for lan connection. I have two separate networks on my lan side. (network 1 and network 2)
I have assigned port 0,1 of the switch card to vlan1 for network 1 Ports 2,3 of the switch card is assigned vlan 20 for network 2
My problem is I would like to applied a bandwidth restriction for all data coming out from vlan20 capping same to 384 kb.
Note I do not want use QOS because this will only kickin when saturation occurs,
