Cisco Switching/Routing :: 2911 TTCP Speed In Different Directions
May 21, 2013
I am troubleshooting some speed issues that I might be having and using TTCP and iperf/jperf. I am testing the LAN speed between our local router and local desktop.
When I run TTCP transmit on the Cisco and receive on the local desktop I get speeds right around 90Mbps, which I would expect because the switch between the Cisco router and the desktop is only 10/100.
When I run TTCP receive on the Cisco and transmit from the same desktop I only get speeds of about 24Mbps to the router.
The router is a 2911 wiht gigabit ports. The switch between the 2 devices is only a 10/100 switch, so I expect to only get around 90Mbps but 24 seems very low.

I am using Cisco 2911 & IOS version is 15.1. My problem is that after some days (e.g. 15-20 days), the routing table suddenly stops updating & then I have to enter the default route again to make it up. I am using Track 1 to track default route here. After primary link goes down, the Track is also going down but after coming the primary link up, the track is not coming up. So, I have to add the default route again to make it up.

I have an ASA 5505, firmware 7.2 (4). Configured ACLs, NAT, it's all working, but after a while it seems that running crashes, no longer makes the directions of NATs, the logs until they stop working. To resolve, I have to restart the ASA, and everything will work again.

we are in the planning phase for a network upgrade. We have two C2960 Switches connected via one (L2) Etherchannel (4x1 Gbit/s) which works very well. In the next phase we would like to upgrade our router to an 2911 series which has 3 gb interfaces. and indeed we would like to create an etherchannel as well. our plan is to use 2 of the 2911 to connect to the first 2960 switch and the one left to the other 2960. i think we will achieve some redundancy with this config.

I have 2 2911 routers that will be connected via fiber with an ethernet Gig handoff to each router. Each router will then be connected to local networks on a second ethernet interface on the router. I have always connected routers via serial connections so this is new to me. Outside of the usual ethernet interface addressing configuration, is there anything else that would need to be configured on the 2 routers?

we have bought 2911 router recently has to set up VOIP line seperately for the network we have two two broadband service provider:
1. how can i use 1 line as an active and other line as a failover(when 1 line is down other line should automatically bear the traffic).clear config will be useful. NATTING using MAtch address objects( roughly )
broadband service provider 1: 97.89.X.X 255.255.252.0
broadband service provider 2: 10.0.x.x 255.255.240.0
2. there are only 20 users to set up a voip line now. here we have telecom provider where they should route the traffic to make any international calls( say telecom public ip 200.200.109.110)from lan - wan everything is allowed from wan -lan we have to allow only telcom provider IP(200.200.109.110)

We have purchased a number of 2911 routers.We got Base & security license as we wanted to enable encryption. However we probably wont use the security.We are replacing 2811 routers.Unfortunately the 2811 routers have FXS ports with 2 - 4 POTS handsets - I completely forgot about these ports when I was ordering.Now I have VIC3-FXS cards which are ok in the 2911 but unfortunately I cant get them to work.I am missing PVDMs (well adapters anyway), and even if I got them the router wont take any commands relating to voice due to the license.Is is possible to 'rehost' the security and turn it into a UC ?I am new to these 2911 and Licensing.

I have a Cisco 2911 router and a Cisco 2960 switch at a remote location.I have a user who will work out of this office a few days out of the week and will need to obtain the same IP address everytime the user visits this office. This office has no file server, no dhcp server. I have the user's MAC address and for now, the user is getting an IP address that is leased for 30 days. I'm trying to find the best way to configure either the router or switch or both so that each time this user connects to this office, that user device will always pull the same IP address and of course no other device will use that IP.
I've did some research in creating a small vlan possibly, and assigning it specifically to the port# that the user's desk is at, but not sure if that's the best way or exactly sure how it'll work. I'm currently studying for my CCNA so this is all new to me and I'm trying to do research and test without obviously causing production issues especially given this is a remote site and I access these devices via putty. I can however drive to the site if needed for testing, but I'd like to have a good grasp on what method I'll be using that will work before I actually make the trip.

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 2801 router that I am replacing with a 2911. I know the ports on the 2911 are Gigabits and the 2801 are Fe. I read where the IOS would not support backup and restore on each other . I am attaching a show ver on both routers. I need to know if backup and restore would work and or what other changes would need to get done.

’m somewhat new to Cisco routers this is my first attempt at getting one to work. I work in an environment with multiple locations, most are using the Cisco Model: 2911/K9 or the Model: 2921/K9 routers running IOS Version 15.0.We just added a new small office and all I had in the way of a router was a Cisco C1841-IPBASE-M router, running IOS Version 12.4.When setting up the C1841 I kept the configuration pretty much the same as the others allowing for the differences in the OS. I can remote into the 0/0 (outside port) from over the network, I can ping to that port without fail, but I can’t send or receive traffic from the 0/1 (inside port).

Two c2911 routers are connected to LAN and have HSRP configured. HSRP is negotiating successfully (active/standby), but LAN switch Enterasys Matrix E1 has problems accessing the virtual HSRP address. The switch can ping HSRP IP, and the virtual HSRP MAC is visible in its MAC table. But the static routes configured on the switch towards the HSRP IP seem to refuse working. Workaround to enable users to access network was to direct the static routes to the physical IP of one router. Is there a known incompatibility between Enterasys with Cisco HSRP?

I have a Cisco 2911 router that I will like to use it for setting up a site to site VPN but the router does not support VPN commands. When I issue crypto isakmp command, it says command no recognized. When I issue ipsec transform-set command, it says command not recognized. The IOS running on my router is c2900-universalk9-mz.SPA.151-2.T1.bin. Also see the output of my show licences features command: [code]

Today I'm going to be re-organzing my network, kind of and I just wanted to get a second opinon. Right now I have an ASA 5510 and a Cisco 2911 and a Cisco 2960 (and I have two more 2911s and 2960s that handles our phone network).
Router 2911 is on the edge Gi0/0 has the public IP and Gi0/1 is not used and then I have 5 individual VLANs (Gi0/1.100, 1.200, 1.300, 1.400, 1.500) VLAN 100 is our internal network 10.10.18.1/24 (router is 10.10.18.1)And the 2960 is used for swichport access, the ASA is on the side and only used as a VPN.
What I want to do is put the ASA on the edge so I can dump all the access-lists and everything then 2911 will only be used to route the traffic. Now I know I will have to reconfigure the VPN, which isn't a problem. My question is when putting the ASA on the edge do I just put the public IP on the ASA's e0/0 and then plug the 2911 into the e0/1 of the ASA and give the Gi0/0 of the 2911 the ip address of 10.10.18.1 or do I just shut it down? The reason behind this is because I would actually like to use the ASA for more than just the VPN passthrough.
