Cisco WAN :: 1841 / Getting Performance Based Routing Setup
Apr 27, 2011
Here is my setup:
Cisco 1841 Software (C1841-ADVIPSERVICESK9-M), Version 15.1(2)T1, RELEASE SOFTWARE (fc1)
Cisco Internal IP:192.168.X.254
Cisco External IP 64.X.X.5 (NAT)
Netopia DSL Router:
Internal IP: 192.168.X.253
Exernal: 76.X.45.3
Now the DSL was installed a while back for a different need and now that need is gone. What Id like to is have the Cisco router do performance routing and send out internet traffic to either its own external IP or send it over to the DSL if it can get a better response. Presently, Since the Cisco is my gateway, the DSL line is sitting idle.

We have a setup of a firewall in between my Cisco 1841 router and Switch.
Cisco Router --> Meraki Firewall--> Switch
Client VPN is configured on the Meraki Firewall but then for the outside users to client vpn in to the network, I have to port forward or open the ports 500 and 4500 to the IP address of the Meraki Firewall 192.168.1.90. [code]

we are experiencing performance issues on ASR 1004 with ZBF as our campus edge router.Symptoms:
- sending small packets from inside zone to outside zone, for example UDP packets without payload
- this way I can generate up to 150.000 pps traffic (testing with packeth software, but we have had a real example with some kind of worm/virus)
- CPU load is about 1% (yes one!) to 2% all time !! (weird)
- ASR response to pings rises very quickly up to 5 seconds which makes box unusable dropping everything what goes through ZBF (so internet connection is gone)
- if I do the ping directly from box, it seems to work fine (no rules from self to outside zone in ZBF)
- if I remove interfaces from inside and outside zone (so disabling ZBF) and do the test again, ASR response goes from normal (0.2ms) up to 2ms (still sending 150.000 pps) and everything seems to work fine)
According to Cisco Datasheets: routing, Qos, Zbf ... on ASR 1000 with RP1, ESP10 should be done in hardware with up to 17.000.000 pps performance.

I'm currently testing LMS 4.2 and I setup a new install. I was able to discover devices, check and backup configs and check for compliance. One thing I can't do is setup pollers to monitor performance. If I click on setup (or any of the 3 options associated with it) under monitor-->performance settings I get an HTTP error 500 from Apache Tomcat. If I click on the monitoring dashboard I don't see any alerts or graphs... Did I skip something during the install?

I have a cisco 1841 router , and i want to configure zone based firewall on it. But the document of zone based firewall only said that "after 12.4(6)T" can support zone based firewall. I use the ios " c1841-ipbasek9-mz.124-15.T9.bin ", but it can't support ZFW. What kind of ios support ZFW. for example: ipbase, ent base, ip service ,advent etc.

The problem I am having is very strange and I have tried to upgrade the IOS on the 1841 to solve the problem but no luck. The issue is when I enable Zone Based firewall security on of the 1841 routers two VPN site-to-site tunnels stops working. If I turn off CEF (no ip cef) then the traffic for both tunnels works. Someone told me that the Zone Based firewall must have a match for the VPN traffic and I created that with ACL 160 and 161 but it did not solve the problem.
Current IOS is below.

The WES610N bridge seems to work fine, but I cannot get into the web-based setup. I have tried using it directly through my laptop, as the instructions show, then through an Asus RT-53N as a router. I did have the 610 connected to my laptop's ethernet socket, where it provided internet through the Asus RT-53N wireless router just fine, but when I tried to access the setup, again, it would not work. Next, I tried it through a desktop and Linksys RVS4000, again nothing. I would like to check the firmware and see what else is in the menu.

XYZ Corporation currently employs eight people but plans to hire 10 more in the next four months. Users will work on multiple projects, and only those users assigned to a project should have access to the project files. You’re instructed to set up the network to make it easy to manage and back up. Would you choose a peer-to-peer network, a server-based network, or a combination of both?

I tried already several times, may be I entered already a name and password, can`t remember. Anyhow this time I was well documented to start again, but after 192.168.1.1, leaving 'name' blank, and password 'admin', this was quoted as wrong name and/or password. What to do to be able to continue now?

I have Verizon FIOS internet/wireless router and then a WRT310N wireless router connected to it thru Ethernet cable. I want to disable DHCP in the Linksys, but when I try to access the set up page at address 192.168.1.1 the Verizon router set up page shows up. I've tried to connect the router directly to the computer, but it needs the internet connection from the Verizon router. How do I get to the set up of the Linksys at the same time the Verizon is using the same address?

I am looking to setup a solution for backing up a Metro Ethernet connection on a 2951 using an 1841 and 2 T1's in a Multilink. The Metro E will be primary, and if the BGP peer goes down, I want it to switchover to the 1841. Can it be done and is there an example of the BGP setup to work off of?

I have got two 1841 and one 881 cisco router. I can keep any one of this router at HO and remaining at branch office. I have got a static internet IP at HO but dynamic IP at branch office. I want to setup a VPN to connect to HO from branch office through router. The branch connects through a private IP for internet purpose. Which VPN is the most secure and best for this purpose.

I would like to set up a POTS Dial connection between 2 Cisco routers, using the modem card WIC-1AM-V2. I'd like to use this as an out-of-band connection to a remote site, if the primary internet connection fails. So, this setup will only be used in one direction, 1 router placing calls, the other one receiving calls.Here's my config of the receiving router:
chat-script dial "" ATZ AT OK "ATX3D T" ATS0=8 TIMEOUT 120 CONNECT C
interface Async0/2/0 description out of band for network no ip address encapsulation slip async mode interactive
line 0/2/0 session-timeout 5 absolute-timeout 10 script connection dial login local modem InOut transport input all escape-character BREAK autoselect ppp stopbits 1 speed 115200 flowcontrol hardware
[code]....
This config is working fine, when dialing in via a Windows Hyperterminal Dial connection. After a while of dialing I get the login prompt of the router.Now I want to have a router placing calls instead of a Windows Server. I can't figure out how to tell a router to place calls to a POTS phone number.
Receiving router: 2811, WIC-1AM-V2, IOS c2800nm-ipbasek9-mz.124-25a
Calling router: 1841, WIC-1AM-V2, IOS c1841-advsecurityk9-mz.124-25a

Is there any official Cisco reference to describe what is considered to be the highest acceptable production CPU load on 2800 routers? I found the document "Integrated Services Routers G2 - Performance Overview" that states at page 5,Most service providers set their CPU alarms to 60 or 65 percent. Many enterprise customers are comfortable running production networks with CPU around 70 or 75 percent.

we are intending to purchase some 887G router for one of our client, but we not sure if it support "performance routing" or not. coz we don't see it on cisco's datasheet, and "cisco feature navigator" don't have that information.

On the datasheet, product specifications are for forwarding only :
Forwarding bandwidth:
• Cisco ME 3400EG-12CS AC or DC: 32 Gbps
• Cisco ME 3400EG-2CS AC: 8 Gbps
• Cisco ME 3400E-24TS, AC or DC: 8 Gbps
Forwarding rate:
• Cisco ME 3400EG-12CS, AC or DC: 26 mpps
• Cisco ME 3400EG-2CS AC: 6.5 mpps
• Cisco ME 3400E-24TS, AC or DC: 6.5 mpps
where can I find the performance for routing (layer 3) for this product ?

I am currently having performance issues running a 3 x stack 3750G (different models) as a core for a network of roughly 12 x distribution switches. [code] As above, I have a 12 port Fibre switch and 2 x 3750G-48 port switches. [code] I tried to change the SDM to route but hit another issue where the 3750g-48 does not support SDM route so I had to revert back to desktop VLAN.Could the SDM Template be the reason for slow performance? If so which SDM Template should i use as this is the Core L3 switch.

I have a new 861 router which I have connected to my home broadband cable modem. Got it all working okay and I have access to the Internet but its not as fast as it is if I connect my laptop to the modem.
My Internet is 60mb (was 100 but I downgraded). When I cannot my laptop directly to the cable modem, I get 60mb download speed on speedtest.net If I connect the router's WAN port back to the modem then I roughly get about 40mb, sometimes even 50.
I do not have any IOS firewall configured on the router, just basic ACLs to stop SSH and TELNET from public networks. If I do enable firewall then my Internet connection halves itself. I have read around that this is the case with ios firewalls on these small routers so I've disabled the firewall but I still don't know why I cannot get full Internet speed.

Pure 3750X-48PS ip base stack.One switch reboots from a power issue (possibly the master switch? Haven't confirmed yet in the 3 cases I've seen)The rest of the stack stays running fine (as it should), the rebooted switch rejoins the stack just fine
What I've observed after this scenario takes place is that network throughput on any port in the entire stack is severely degraded. Prior to the one switch rebooting, I can hit gigabit transfer rates going anywhere on any of the switches in the stack. After one member reboots by itself, I typically hit a transfer wall around 5-20mbps in one direction and sometimes better going the other direction. I've only confirmed this on 3750X stacks and I can replicate it every time. Newest code I've experienced it with is 12.2(58)SE1. I have not seen confirmed reports of this on older 3750 (E, G, plain) stacks of which we have a ton of.
Rebooting the entire stack so that all 3750X members are coming up at the same time solves the transfer rate issue every time. I would think there has to be a better way to get performance back to normal or prevent the performance hit in the first place.
