We have a RV042. remote management is set to DISABLE - but even after restarting the router i can access the interface remotely over the internet.even when i enable it and change the port to say 5555 i can connect to the web interface using either port 5555 but ALSO on port 80.what's wrong here?the only way to stop that was to create a rule that blocks port 80 on the WAN interface. (btw. could this rule affect LAN users when browsing the web?)

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.

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.

View 1 Replies View RelatedI 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:
607 in free list (500 max allowed)
9071 hits, 0 misses, 618 created
Public buffer pools:

68 in free list (20 min, 150 max allowed)
7083 hits, 74 misses, 0 trims, 21 created
55 failures (0 no memory)

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.
I have a such setup:Code:

We'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.

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.
Our 2811 WAN router is experiencing a high volume for huge buffer misses with some failures. Should we look into the automatic buffer tuning command as our IOS supports it. Does the router need to be reloaded after? Has anyone experienced any issues with this command or having traffic dropped (even biped)?

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.

I have a customer that is seeing output drops on a 2960S with mls qos not enabled. It appears that they are getting bursts traffic on the switch that is filling up the buffers, hence causing the drops. I have a couple of questions:
1. What are the default queue/buffer settings when mls qos is NOT enabled on the switch.
2. Is there any good documentation out there regarding the buffer sizes of the different switch models
The customer is looking for an answer as to whether or not replacing the 2960S with a higher model would eliminate the output drops WITHOUT having to mess with QOS/buffer/drop threshold settings on the switch, and Cisco doesn't seem to make the buffer sizes readily available for the the smaller Catalyst switches.
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
