Cisco WAN :: 2621XM / IP Accounting And / Or Ip Cache Flow Stats?
Dec 15, 2010
I have a Cisco 2621XM router with two ethernet interfaces that sits before a vendor supplied VPN router. I need to see the IP traffic incoming to my router from the WAN side (fasteth0/1 below). I setup ip cef, and ip flow ingress on the interface. However -- it seems that what I see when I use "ip cache flow" command doesn't have a very long history or life. What commands am I missing so that I can see a summary of the stats over say the last 5, 10 or 15 minutes? Is this the best config that can be used for this, or can I create a more summarized report just using the router HW and IOS? Basic current configuration:version 12.3service timestamps debug uptimeservice timestamps log uptimeservice password-encryption!hostname Littleboy!ip subnet-zeroip cef table event-log size 1024ip cefip cef accounting per-prefix non-recursive prefix-lengthip cef traffic-statistics load-interval 180!ip flow-cache entries 2048ip flow-cache timeout inactive 60!interface FastEthernet0/1 description Littleboy to vpn-wan ip address 10.1.0.1 255.255.255.252 ip flow ingress?

On my 1841 when i enter the "ip flow-cache timeout active 2" command it accepts this command with no errors. But when i look at my running-config this does not list.I did the same thing on my 2811's and 3745 and it shows up in the running-config. Should I assume if it doesnt' show up in my config file than it is not applied? How can I verify that it is or isn't?

How does one find the top user or IP accounting with this ASA5505 v7.22 device?
-With 1841 ISR:
-sh ip accounting
-sh ip flow top
Very lame if they don't have similar commands or capabilities on the ASA series.

Ever since we switched to ASR1004 running XE15.1(2)S1, we have seen that the output of "show ip cache flow" stalls and is super slow to complete. We have a few interfaces with "ip flow ingress" defined. What can be causing this slowness? Any recommendations of commands to speed up the output?

Struggling to find any documentation that states both "ip accounting & netflow" are supported on the new ME3600 switches. I have tried both a 12 and 15 release of software. Netflow produces no data what so ever, ip accounting only produces data (of the global network) when configured on my uplink (running MP-BGP network) unable to get specific data for user networks in seperate VRFs. Is this a case of the commands being there but not being supported?

I am not sure if the issue I have is due to router's performance of my configuration. Currently I have 2621XM connected in my internal network where Fa0/1 is considered untrusted zone and Fa0/0 is considered trusted. It appears that traffic is limited to about 3.17MBps (Mega Bytes) between Fa0/0 and Fa0/1. There are ACLs on the Fa0/1 inbound and Fa0/0 inbound. I am also using ip inspect rules for the Fa0/1 outbound traffic. When I remove ip inspect policy from the Fa0/1 interface, the traffic speed bumps up to about 4.8MBps (which is about 38Mbps - Mega bits).
Each time the CPU utilization is: CPU utilization for five seconds: 99%/99%; one minute: 19%; five minutes: 4% PID Runtime(ms) Invoked uSecs 5Sec 1Min 5Min TTY Process
Access to the router during that time is veerrrryyyyyy slow! Does this mean I am hitting the maximum limit this router can handle?

I've got as Cisco AS5400 Ver 12.3(22) with the E1 controllers acting as ISUP TG (pri-groups). Since we have no streaming for call records to RADIUS serving etc. is there a way to setup a log or history buffer for alerts for traffic congestion? With high call rates the "normal" realtime methods of using >sh call active voice breif | i No Circuit Avail wouldn't be pratical since memory/processor usage could be an issue. The >debug isdn q931 interf dch 1/0 would of worked but again so much traffic is coming I don't want to increase the size of the logg buff >300K.I guess I was expecting an easy way out being an old TDM salt used to the 5E/Telica Plexview/DMS having CDR and Traffic Stat info readily available. I know the AS5400 is a powerful device, maybe I just haven't got the right command down or totally overlooked the obvious.Oh, and this is connected to the Cisco PGW/SGC 2200 Version:"9.3(2) and I haven't found anything in it's logs.

I was just wondering on the stats page of my DIR-615 the WAN Stats is in packets. How do I convert that into megabytes and gigabytes so I can track my usage?
Since AT&T put in caps and do not provide a usage meter. I would like to keep track of my usage.

I've got a 2621XM that has not been used for a while.Completely stripped of any modules and configuration files, the router will continually cycle the startup process without actually booting from the IOS.
The cycle displays the following :
System Bootstrap, Version 12.2(8r) [cmong 8r], RELEASE SOFTWARE (fc1)
Copyright (c) 2003 by cisco Systems, Inc.
program load complete, entry point: 0x80008000, size: 0x10034ec
What I've tried:
1) Downloading another IOS image (c2600-is-mz.123-20.bin) via Xmodem and running "confreg 0x2102" from the rommon. All that did is change the last message to "program load complete, entry point: 0x80008000, size: 0x10fa95c"
2) Running the command "boot flash:c2600-is-mz.123-20.bin". If I enable the diagnostics via rommon, the cycle expands to:
System Bootstrap, Version 12.2(8r) [cmong 8r], RELEASE SOFTWARE (fc1)
Copyright (c) 2003 by cisco Systems, Inc.
program load complete, entry point: 0x80008000, size: 0x10fa95c
Testing lower main memory - data equals address
Testing lower main memory - checkerboard
[code]....
If it wasn't for the lack of error messages, I would assume it was a hardware issue.If the image was corrupted, I would expect a message indicating that the image couldn't be read.

Is there a good reference in how to interpret the "show AP stats" command?
I have a new (online for 15 days) 1142 listed below. It is the first 802.11n AP I've deployed. The stat counters look bad [code] But I don't know how to put it all together to say "here are the stats, this is the problem". I see TxFrameCount, but no corresponding RxFrameCount, so it is hard to calibrate some of the errors. [code]

I'm trying to login to my cisco 2621XM router. I'm using putty and I can't remember the how to cable it or the settings to use in putty. I don't have a db9 input on my pc, so I need to go through my NIC. What type of cable to use, what port to plug it into on the router, and what settings to use in Putty.

I have an old 2621xm router in CCIE lab at home. Only a week ago I started having issue on 2 of them. The problem is on one of them when I go under interface configuration and I type "no shut" nothing happens. Interface stays in administratively down status and when I check running config "shutdown" is still under interface.
On the other one the same problem but only with "router rip" command. I configure my rip routing but then when I check running config there is no rip section and also RIP is not running under "show ip protocols rip".These routers are connected to 2511 AccesServer. So I thought the issue might be communication from AccessServer to these devices. I connected a console cable straight to them and still the same problem. Everything else is working on these devices.

I have a 2621XM router that I know has reached its end of life. However, would I be able to download the 802.1q VLAN encapsulation for it? If I can, how do I go about doing it.

I've got a WRVS4400N wireless router running DHCP for a couple dozen wireless clients in a public library. We need to gather statistics on the wireless clients on a daily basis: average number of clients, max number of clients, average time used per client etc.
The router only gives a list of clients currently allocated an IP address, but there doesn't seem to be a way to gather statistics over time. Is there a program that will interface with the router to gather more detailed statistics?

I'm trying to use Cisco IP SLA to bench mark voice traffic peformance before and after I apply QoS to the network.
* I've setup IP SLA in both directions over a DSL connection between a 7600, and an 1801
* I've setup IP SLA in both directions over an Ethernet WAN link between a 7200 and another 7200
ip sla 1
udp-jitter 10.101.1.1 32770 source-ip 10.101.2.1 source-port 32770 codec g711alaw

!
ip sla schedule 1 life forever start-time now
!
ip sla responder
!
I have a problem in that I'm not getting any meaningful data from the IP SLA statistics for Voice Score Values:, or any data for Latency one-way time: for any of my tests(x 4).
After a day of testing it seems the MOS score never changes from 4.34, and the ICPIF never changes from 1 ?Is there something wrong with my config? Is this working properly or could this be a bug?
ADSL-R1#show ip sla statistics 1 details

On my old router I could access the line stats on the home page giving me Attenuation and SNR margin, this allowed me to keep an eye on line quality, there seems to be no equivalent info on the X2000. Is this on a hidden page like the advanced wireless page.

I'm having with my VPN Server on my Cisco 2621xm.
I started by creating a VPN - everything worked great. I assigned the DNS Servers, Domain name, WINS Server so when I connect I'm able to resolve local hostnames on the network with no problem, however, I had no internet access... I then set up a split tunnel access list. Since I've set that up, I'm now able to ping internet based addresses url... but no longer able to resolve internal host names. I can ping the ip addresses, just name resolution no longer works. [code]

In our environment we have some HP chassis, and with them there are blade switches. Lately, we've been seeing some drops on few servers connected on the blade switch ports. The switch model is WS-CBS3120X-S. And below is the tx drop for two interfaces ( where the servers are connected to).

I develop websites, and we moved a site from one server to another, and now I get the message the site has moved. I ran the cmd to clear the dns cache, but that didn't solve the issue. I tried stopping and restarting the client, that didn't work. It was already set to automatic. I am logged in to my laptop as an administrator. I tried to be the user Administrator, but it doesn't appear as a choice, but when I try to change my name, I get the message it is already in use. I am using XP Pro, SP3?

I have to do ipconfig /flushdns from my Laptop to access my PC, on my local network, for some reason when the Laptop is booted up.After that all works like it should. I made a batch file to do that command during Windows start up. Is there any reason why I have to do this or is it just something quirky with Windows?Both computers have Windows 7 Pro 64 bit. Both use the same DNS servers.
