We phace disconnections when having a dozen open connections.Does the Cisco devices have a documented limitation on the buffer size or the number of telnet connections?
View 1 RepliesIs there any way to check how much of the total buffer size is utlized at any given moment out of the total space or memory allocated in Cisco 4500 switch For eg - show logging output is as below for a 4500 switch
Syslog logging: enabled (0 messages dropped, 1 messages rate-limited, 0 flushes, 0 overruns, xml disabled, filtering disabled)
Buffer logging: level debugging, 31644 messages logged, xml disabled, filtering disabled
Exception Logging: size (8192 bytes)
From above is there any command to check hw much size is currently utlized , by 31644 messages ..or how much of the located buffer size is utilized.
I was wondering about command of Linkset subcommand at ITP7613.I have been using the Cisco7613 chassis for the ITP(SIGTRAN) service.
However, i know that the "tx-queue-depth" command is used for sctp multihoming buffersize that between primary and secondary path at the Link sub-command mode. but i can't adjust the changeover buffersize(retrieval buffer) that between link and another link at the Linkset subcommand mode.
It's above my comprehension.
My guess is that related to "plan-capacity-rcvd" command. it's right?I want to know command that adjust the buffersize of Link changeover.
Cisco Prime LMS 4.2.3 is sending SNMP request too big for asa interface buffer.LMS is running on Windows server incoming SNMP request (528 bytes) from IP address x.x.x.x Port 50592 Interface "inside" exceeds data buffer size, discarding this SNMP request.
212005: incoming SNMP request (%d bytes) from %s exceeds data buffer size, discarding this SNMP request. It is very much like this error
Error Message %PIX-3-212005: incoming SNMP request (number bytes) on interface interface_name exceeds data buffer size, discarding this SNMP request.
#Explanation This is an SNMP message. This message reports that the length of the incoming SNMP request, destined for the firewall, exceeds the size of the internal data buffer (512 bytes) used for storing the request during internal processing; therefore, the firewall is unable to process this request. This does not affect the SNMP traffic passing through the firewall via any interface.
#Recommended Action Have the SNMP management station resend the request with a shorter length, for example, instead of querying multiple MIB variables in one request, try querying only one MIB variable in a request. This may involve modifying the configuration of the SNMP manager software.
how do I change the SNMP request size in LMS? I can only find the following that might be an option

I use to could be able to watch videos and listen to music, and download at optimal speeds, I could even watch HD if I wanted to, but now all of a sudden (starting at least 3 weeks ago) videos, downloads, and music seem to run super slow no matter what quality I have it on. It takes 5 minutes to buffer a 3 min video, and if I want to watch a show, it take like 2 or 3 hours to fully buffer. My internet still goes fast, and I have trendmicro antivirus, as well as ccleaner, i updated my drivers, i have ie9 and adobe flashhplayer 11.1, i updated everything in windows update, i unplugged the modem for awhile and shut down more often, and opened it up and blew all the dust out. I don't know what else to do. I do have a cisco E2000 wireless router if that's a problem, and both my ps3 and my computer are on the connection, but my computer was working fine with both on the same connection for a year. I go on the http:192.168.1.1 cisco place, and i renewed ip settings, and nothing worked.
View 19 Replies View RelatedAbout a week ago, without any change to my network settings, I began having a problem with streaming 1080p content from my media server to a router, wired to a switch that serves a few devices in my home theater (including a HTPC, my Boxee Box). Every 15 seconds movies have to buffer. After a while, I narrowed it down to the switch, since wiring the Boxee Box straight to the router caused the movies to run perfectly.Logically, I thought the switch was the problem, since I really made no changes on my network/DD-WRTRouter other than running a Minecraft server (which shutting that down made no difference in network performance).
I ordered a brand new gigabit switch, same problem. Pinging the BoxeeBox returns 0 packet loss whether it's connected to the switch or router, but movies still play perfectly fine when directly connected to the router. Different cables didn't work. Ok, well, I thought maybe the other devices on that switch were causing some sort of conflict.. changed the BoxeeBox's static IP just in-case, unplugged every other device from the switch so that only the BoxeeBox and Router were connected to the switch. It worked fine! Yay! Tried a different cable, still worked fine. Great, I thought, so the problem was never my switch... plugged the old switch back in, then the problem returned.
Changed back to my new switch (each time power cycling all of the network devices) and the problem persisted, even with the SAME EXACT setup I just had a few minutes previously that worked fine. Tearing my hair out at this point.Since that moment I still haven't been able to reproduce a perfect stream unless the BoxeeBox is directly connected to the router. This doesn't make ANY sense as I had this setup running perfectly fine since November 2010. I am COMPLETELY out of ideas other than running multiple ethernet wires to that drop or running all the other devices on wireless.
I would like to define a general policy for our company to set the log buffer ("logging buffered xxx"). Currently, most of our configs use the default value of 4096, which does not store much of the history. I'd like to see more, when logged onto a router. We are using different router platforms (from old 1700 up to 39xx oder 72xx) Can you give me any hints, how large the buffer can be set on a platform? Which checks should I do to determine, how large I can set the buffer?
Here's an example of a Cisco 1720 router:
Cisco1720#sh mem
Head Total(b) Used(b) Free(b) Lowest(b) Largest(b)
Processor 81AECE9C 17803244 5548816 12254428 12010916 11815908
I/O 2B43000 4968448 1560416 3408032 3374144 3396668
Cisco says: "Total = the total amount of memory available after the system image loads and builds its data structures."So, in this example, the total bytes are 17803244, which is ~ 16.9 Mbyte. So, if I allocate 64000 bytes, my total buffer will decrease to ~16,3 Mbyte.
I my calculation above is correct, I see no problem in defining a standard value of "logging buffered 64000" for every router platform - even under high load conditions. Since 64 kbytes is a very small value compared to the total usable memory of a Cisco 1720, newer platforms should not have any problems either.
I have a 2851 and a 1841 both serving as hub routers in a GRE multipoint configuration. They are both receiving buffer misses and failures on startup. I will post the output of show buffers below:
LAB-HUB-RTR#show buffers
Buffer elements:

I have tried increasing the small/medium buffers initial size and permanent size, however there is no change. The buffer failures for small and medium buffers are always around this many every boot.I have also changed the IOS versions between 12.4.24(T4) to 15.1 with no luck in stopping the failures.
Does the limitation on ASR 1000 series RP1 with regard to maximum number of match statements per class-map?. I have more than 30 match statements under my class-maps but when I apply the service policy on the interface, I get the error "cannot configure more than 16 matching statements per class-map for the interface”.I am running 3.1.0 S on an RP1. Is it a hardware limitation just like the older Cisco 10Ks?

View 3 Replies View RelatedWe're having some issues with a 3560 CPE. It's uplink is a GE fiber link, customer port is FE RJ45. We see a lot of TX-frames being dropped at the FE port,but none at the GE port. Even when the customer is only at ~50Mbit/s downstream traffic. When customer sending ~50Mbit/s upstream, there are no TX- drops at the GE link. Is this a normal behaviour? From what I know the physical medium shouldn't have any inpact on this since drops occurs in the port- asic, and not in physical transmission.Do the buffer-sizes between GE and FE differ? What could we do to optimize the flow and reduce drops? QoS is set to off and no modifications on the queues have been made on the interfaces.

I have a NMWLC6 module connected to a 3825 ISR using 1140N APs. Latest (but one) code. I had two SSIDs configured and deployed in the default AP group. Last week I needed to deploy a third SSID for unencrypted webauth, I created the interface and WLAN associated with the interface and the sub interface/svi on the WLAN-controller 0/1 with dot1q. All created with no problem and enabled, however the SSID was not available to clients and did not show up as available WLANs under AP groups menu. Out of desperation I created a new AP group and added an AP to it and hey presto all three WLANs were available and the third is now visible to clients! Is this normal behaviour? Is the default AP group limited to two SSIDs? (a quick google failed to find any documented limitation!) or is something weird going on?
