when i type "show interface" command on 1941 router, shows below print. Why 5 minute input-output rate are 0 bits? Can it be a bug?
5 minute input rate 0 bits/sec, 0 packets/sec
5 minute output rate 0 bits/sec, 0 packets/sec

I found increasing of total output drops and output queue drops even input rate was low and no qos apply on this interface. I plan to increase hold queue out for output queue.

On my SUP-7E, when I issue a " show interface vlan X " I cannot see the expected input/rate reflecting the real rate (which should be very high).
5 minute input rate 0 bits/sec, 0 packets/sec
5 minute output rate 4000 bits/sec, 2 packets/sec
(Under the physical interfaces it is ok)However on other SUP-IV I can see the real rate.
My questions are :
- Why the SUP-7E does not reflect the rate, whereas the SUP-IV does ?
- I have heard about the 'counter' command under the vlan interface to activate the rate counters. Is this command application has any side effect on the switch ?
Our customer get the problem that the switch count the 5mins input/output rate of connected traffic interface always ZERO.The problem only occur in the module 3,4 and 5 interface, module 2 has no problems.

I have this topology in part of my networ:k
Cisco7200---Cisco6500---Cisco3560---LAN1
|
Cisco3560

LAN2
All devices are interconected via optical 1Gb/s links. There is no QoS implemented on any device and all VLANs are allowed on all interfaces.
Also all links are trunks (with many VLANs)
In LAN1 there was a layer 2 broadcast-storm and 4000packets/s was comming to rest of the network (in one particular VLAN).
1) 7200 with G1 should be able to handle traffic up to 500Mb/s, but a lot of users experienced drops on traffic via 7200.
(CPU load was around 10%).
2) Why do I have input drops on 7200 on link toward 6500 if CPU was normal. Broadcast comming to this interfaces were cca 4kpps. But since it's destination is not on router these packets should be rejected on interface controller. Is that right? (7200 doesn't even has dot1q subinterface in that VLAN but since 6500 allow all VLANs on its trunk these packets reach 7200)
3) Why do I have output drops on Cisco 6500 (it is here as layer 2 device only)? It is max 160Mb/s in output direction. It has WS6724 card with DFC (there is no oversubscription).. Shouln't 6500 send traffic as fast as interface allows (up to 1Gb/s). Am I righ't?
4) After all how coul'd 6500 now if 7200 can't handle these traffic?Output drops should be only seen if QoS is enabled (i.e. shaping), or if there is oversubscription on the linecard?
We have 7206 VXR running NPE-G1, we are looking for the GigE cards for 7200 which supports upto line rate and came across Cisco 7200 Series Input/Output Controllers The datasheet for the same doesnt say anything about line rates.

On the router itself, in addition to the four Ethernet SFP ports, there are four additional RJ-45 ports. They're labeled "BITS", "MGMT", "CON", and "AUX". I know what the Con and Aux ports are, but what are the Bits and Mgmt ports? And is one of them the Gigabit Ethernet interface that I see listed at the bottom of the output? And if it is, is there anything special about it, or is it just another routed Ethernet port? Can I do something special with it, like out-of-line managment?

i, as same as a ton of users, really get dissapointed because the driver in the cd does not work on win 7 and the 'official updated driver' is useless as well, and in the end lost a lot of time searching almost in the entire internet for a solution, that some pages claim to have, but the info is oudated, or the links are gone.so in a insurmountable-almost-titanic search, i somehow managed to gather all the required files that i'll put at disposition of those like me have a bad time with a supposed to be a pretty good wireless card.
1- bmc 4329 v4.100, this one is the most 'stable' and works pretty well in 32/64bits, it had a modded .inf wich enables a few features that various users will find pretty useful, when the installer prompts a warning about an unsigned driver, you had to allow the installation
2- bmc 4329 5.100, this one is working too on 32/64 bits, i'm posting it because some people got problems with the 4.100 version, however, the 5.100 is a stock unmodded driver, so maybe it will give connection issues.

I have an ACS 5,2.0.26-8 running on VM intergrated with RSA. Users are able to login using their RSA passcode for network management utilizing TACACS. The problem seam to be related with RSA token caching. Once a user login sucessful on device A using current token he can not login with the same token on another device. User must wait for a new token and then he can login again. Before moving to ACS 5.2 we were using ACS 4.2 (intergrated with the same RSA) and back then ACS 4.2 cache passcode so user where able to login on devices using the same passcode. When the token change user have to use the new one. providing the same functionality like the "Token Card Settings" Durantion option under group properties, to cache token for a specific period. The global option for caching under RSA definition on 5.2 does not solve the problem.

View 4 Replies View RelatedWe had an issue the other day where doing backups through the firewall (don't ask) caused the "control" session to timeout while the backups were still going on over the "data" connection. This broke the backup about two hours into the job. My first thought was that the backup solution vendor should implement some kind of tcp keepalive for the control connection. A packet capture showed they indeed were -- after 2 hours! Ah ha! Busted! How could they choose such a poor choice of TCP keepalive timer for their application that would not be compatible with the 60 minute inactivity timer that so many firewall vendors use (Cisco, Juniper, Checkpoint and Fortinet all use a default 60 minute inactivity timer for TCP)?
Well, a colleague of mine pointed out that there is actually an old RFC that covers this. RFC 1122. It says:
Keep-alive packets MUST only be sent when no data or acknowledgement packets have been received for the connection within an interval. This interval MUST be configurable and MUST default to no less than two hours.
Now I know that RFC is old (October 1989), but that's all I could find. Is there something that supercedes that? Maybe common sense perhaps? I understand not wanting to fill up your connection table because of mis-behaving applications, but I'm just looking for ammunition to use against the backup solution vendor. Surely they're going to point to this RFC.

View 1 Replies View RelatedThe problem I am having is my wired internet connection is going out every minute or so and stays out for about 1-2 seconds at a time sometimes it stays out for around 3-4 mins usually twice a day. This problem has been occurring everyday for the past 2 or so years some days it is worse. I have power cycled the modem and router many times, replaced the router, replaced the modem bypassed the router and it always does the same thing. I have gotten cox cable to come out many times, once was to replace the modem, and it conveniently does not have problems when they come then i look stupid. I have showed them the screen shots of the outages from pinging multiple points on the network as shown in the attached screen shot, as you can see in window labeled 1 is a continuous ping of google.com, window 2 is the first hop on the tracert as shown at the bottom of the picture, window 3 is my modem, and window 4 is my router.
As you can see I never lose connection to my router or modem and it is the same when i run tests from other devices. Every time I call them or show them this picture the only response I get is there are no reported outages and to try to reset my modem and router or they can send a tech. When the tech comes there seems to be no problems and I show him the screen shots and he writes it off as peak hour malfunctions even though it does it at non-peak hours as well. Then when he leaves It starts to freak out again I have gone through this scenario at least 3 or 4 times and at this point am getting very frustrated. Even though it is not very noticeable with normal web browsing in gaming and streaming it is a nightmare. I would have already switched service providers if there were any other that service my area.
I keep getting disconnected and blocked from using even LAN on my computer. This happens whenever I visit certain websites. For instance, I registered on a website that has me "kept signed in", and whenever I click to view that website, it partially loads and then for precisely 1 minute any network activity I try (like visiting my router configuration page, or clicking refresh or home to load google) will not go through. Only after that one minute is over with, I can resume browsing that website; however, if I leave it for too long, and then return, the same thing happens.
I've also noticed that if I sign out of that website and then visit it, that disconnect issue won't happen.But that isn't the case with other websites, as they require no accounts and are just pages with news and other stuff.I tried uninstalling and reinstalling my ethernet drivers, tried flushing dns, renewing ip, releasing and some other /cmd stuff that I found online.This also doesn't happen on any of the computers connected to my router (although, they are all using wireless - I am using cable to router).I'm on windows 7 x64, using a realtek ethernet card, Nod32 security suite (think it may be the settings on this thing? I set everything to super safe settings so I don't get any dumb viruses). Windows is updated (well, at least 3-4 months ago it was updated). I have no idea what is causing this, and why the precise 60 second interval until I regain access to the internet.I'm using Firefox, but this also happens on IE8 or 9 or whatever I have installed, so I don't think it's a browser issue.Things like facebook, youtube, pennyarcade and other junk work, but as soon as I go to google looking for, say, apartment rentals and open some pages, one of the links in the search results is bound to make my connection freeze.
I have Broadband Internet and TV through Time Warner Cable. In the past week I suddenly began to lose stations on my cable box from what seemed to be a loss in signal so I had tech support come out to take a look at the problem. Turns out the problem was the wiring in the cable box outside the house. The wiring was over a decade old and had been damaged by water and ice over many winters. Tech support guy replaced all the wiring and the cable box is back to normal!However, after sitting down to use the Internet afterwards my connection kept "dying". Every ten to fifteen minutes or so the connection would seem to die for a minute or two.
All devices connected to the router either wired or wireless experience the issue at the same exact time. Windows diagnosed the problem as "DNS Server Not Responding". Now my router setup has been working for years, and nothing has been changed, so I thought maybe it could be related with the issue with the cable wiresHowever, researching the DNS issue on Google makes me think it's just coincidence.
I rebooted and power cycled the modem and the router. The issue persists. Updated router firmware. The issue persists. I changed my DNS settings to use OpenDNS. The issue persists. Changed DNS settings back to automatic. The issue persists. So I disconnected the router and plugged the modem directly into my main PC and the issue was completely resolved! Hooked up the router again and the issue popped back up after ten minutesRepeated all the troubleshooting steps and the issue persisted through them all.
