Our office lan network is in 192.168.0.0/16 with 300 nodes and 30 server .Since its a large broadcast domain some times it takes large time for copying files.How can we avoid this problem with out changing the subnet.Also how to avoid broadcast storm.we are using cisco 2950 series switch.
View 10 RepliesI'm looking for some software for copying large amounts of data from a Mac OS X machine to a Windows 7 machine over a Cat5e cable with IPv4 connectivity?
Another way I could ask this question is what IPv4 protocol will have the lowest overhead so that I may copy large amounts of data the fastest?
Also, would that mean it's a low-level protocol, like transport layer?
We are having issue with all our Cicso wireless devices (AIR-AP1142N-N-K9) when connected to Windows 8 Pro users. When copying large files, the connection changes to limited access. The initial connection to the access points is also slow for both windows 7 and windows 8 pcs.

View 1 Replies View RelatedI have a Cisco ASA 5510. I am trying to copy large files between DMZ and INSIDE network and it is copying at awfully a slow speed. I thought it might have been related to duplex mismatch but it doesn't seem to be. DMZ interface is set at 100 full duplex. I programmed the port on the managed switch where the DMZ uplink is connected to be 100 full duplex. I even hard set the NIC on server to be 100 full. Nothing worked. So, I come to a conclusion it isn't the duplex mismatch but there gotta be something else on Cisco ASA. I was googling for this issue and came across it could be a QoS policy. Now, checking my ASA I see a any to any global service_policy where it is defined to inspect certain protocols where 'netbios' is one of them (among others such as 'ftp', 'tftp', etc. Could the slow copying be related to the above policy? Could there be a bandwidth limitation between DMZ and INSIDE interface? How do I check?

we just deployed a cisco wireless solution with WLC4404-100, WCS, and a bunch of 1130AP and I experience some problem with file copy under windows xp. The file copy is working fine with my Ethernet connection however.The symptom is as follow. I cannot copy large file from a share to the computer. The copy starts then after a while (let's say 30MB copy over a 100MB file) it stops with the error 'File copy error: The network name is no longer available'. When this occurs, I still have my wireless card connected and I can ping my computer from the controller.I tried to adjust some radio settings (channel, power on the AP I'm connected to) because we have a large wireless network here, but no success. I also update the wireless card driver, create a new SSID, etc. No success at all. However the copy went fine for small file size.

View 1 Replies View RelatedI'm presently experiencing an issue with my Latitude E5410 notebook where the NIC disconnects during large file transfers. For instance, if I were to copy a large file (50+ MB) from a network drive (or vice versa, copy a 50+ MB file from my notebook to the network drive), the network icon in my taskbar suddenly changes to "No Network Access", the transfer fails, and I can't access any network resources until restarting my workstation.
At first I thought it was the network backbone in our office (SonicWALL Gateway + Dell PowerConnect switches), but this error also occurs at my house with my own networking equipment (D-Link) and NAS. The Latitude E5410 notebook is running Window 7 Professional SP1 and has a built-in "Broadcom NetXtreme 57xx Gigabit Controller", and a "Dell DW1501 Wireless-N WLAN Half-Mini Card". However, this issue seems to only occur with the Broadcom adapter when I'm physically connected to our network; when the Broadcom adapter disconnects, I can connect to our local wifi network and access network resources.
At home I have a perfectly working test setup for more than 1 year now , but yesterday we had a power down for about 10 minutes in the whole area , after this power down nothing was working in my network any longer.
My Network is has follow :
ISP(Cable Modem) on FA23 from the CISCO 2950 SWITCH (24 Ports)
ROUTER (ON A STICK) on FA24 from the CISCO 2950 SWITCH
And the rest of the switch is FA1=VLAN 1; FA2=VLAN 2;FA10=VLAN 10
Our home network is connected to VLAN 10 with a IP Range of 192.168.10.x /24 After this power down , I was not able to look into the SWITCH via FA1 , the FIX IP in this switch was 192.168.1.251/24, the ONLY way to get access was via the consol port !!!What a suprice when I connected my consol to the PC , I can see ROUTER_F342 , my router config is called ROUTER1841 and my switch config name is /was called SW24.So it seems that after this Power Down , the router took or received a config from my provider ?!?
I have recovered the the file in the switch + the vlan.dat and now everithing works again.
How can I avoid that this switch receive again a wrong file , I have all the needed files on the products itself and I do not use a TFTP server.
I have atached some screen shot when my switch is starting up , and it seems that the switch receive a IP address from my ISP , I do not know why, in the config file I have given it a FIX IP 192.168.1.251/24 ?!?So it seems that my ISP erase the config file and when the switch is empty ,the swich look for :
tftp://255.255.255.255/router-confg
tftp://255.255.255.255/ciscortr.cfg
Etc ....
Until it find something.
I have tried after a complete recovery to switch off the power again for 10 minutes (ISP MODEM + SWITCH + ROUTER) and I was not able to reproduce the fault.Can it be that due to this power failure in our area that some routers or switches send or broadcast this kind of things ?
I have the Cisco 3560 switch. I can ping both from switch to server or from server to switch. However, I cannot ping with large size, for example,
ping 192.168.1.1 size 10000 (failed all).
I can ping 192.168.1.1 size 5000
(the size allow between <36-18024>)

We have a brand new 2 x 3750-X stack running 15.0(1)SE3 with C3KX-NM-10Gs installed in each switch. An HP C-Class server enclosure with Virtual Connect Flex-10 modules is connected to each of the 10G ports using twin ax cables and they seem to behave OK apart from some random packet drop which appears to be within the enclosure and not without.
However, when we were investigating this, we found a little oddity ... even though we have jumbo frame support enabled on the 3750-Xs, we are getting a significant "Valid frames, too large" received count on the interface, and a "Too large" transmitted count. I've looked around and can't find a definitive reason for this count to go up - it doesn't seem to be a jumbo frames thing, more an unexpected-additional-field-in-a-header type thing, like when you have a V LAN tag in a DTP frame. Any thoughts as to why I might be getting these from a new server enclosure?

I have an 1841 and started to run into an issue which can be resolved but looking to see what you guys prefer to do in this situation. We allow users to connect the laptop via ethernet and wireless to our network at the same time as well as an iPad or any other wireless technology. With that said, for the most part each user has two IP's at any given point. The issue comes in is that I have a large amount of IP exclusions for servers, printers, switches, etc on the exclude list. I am starting to see that the 255 address are not enough to make a long story short. I am also using the 1841 to handle another range for the voice network, which has no isues. What is the best way to fix this issue? Can I run a virtual VLAN off that 1841 for everyone to use and then have the servers, switches, printers, etc on another one? I want to assume no, as both interfaces are used on the back of the 1841 for the two VLANS running now. Or is the only way to handle this with this device to say that as a policy you can only connect assigned company hardware to the network?
View 3 Replies View RelatedWe are migrating from Catalyst 6509 IOS platforms to Nexus 7009. There's the normal differences in commands which is well doucumented. We do have some quite large files containing ACLs varying from 10's of lines to several 1000's of lines. Our normal upload would be done using tftp and then issuing the command 'conf net' on the the 6509. This is no longer the way to do this on NX-OS. I've tried copy ftp: running-config which works fine for small files but for big ones it takes a long time, in some cases I've see it takes 20-30 minutes. The initilal tftp uplaod to the 7009 seems OK but the copy into the running-config is the bit that takes time and initially I thought I'd killed the 7009!! It did finally come back to the prompt. Are the 7009's simply not designed for large ACLs? I did try the configure session (Session Manager) but I couldn't see a way of uploading a file. I tried creating a new session and then exiting it, copying in a file of the same format and then commiting it but it didn't seem to acknowledge the file (checksum?).

In figure 14 of REP pdf URL can you explain why this creates a loop in the system? From the document, I thought REP and RSTP could talk to each other so why does this create a loop if they are exchanging information between each other? Also, if, in figure 14, the two switches in the STP domain that connect to the REP ring, were also connected to each other, would there still be a loop in the system?
Also, what is the recommended max diameter a REP ring should be. I thought I read some place 130 nodes is ok, but I'm looking to confirm this.
we have two 6509E, as our core switches. Recently I noticed that on some connections I have a high output queue drop rate.
These 4 x 2 interfaces (gigabit) are connected to our blade encolure, consisting of 4 x WS-CBS3120X-S. The utilization of the links is really quite low, when I see the increase of the drops. (~=60Mbps). All the links are fiber (SFP) and the distance between the core switches and the enclosure is about 15-20m.
I am not aware of any service degradation on the part of the servers. No CRCs, collisions etc, on the interfaces, apart from the drops.
The line card is a WS-X6748-SFP, but other interfaces don't seem to be experiencing any problems.
My customer has various Cisco switches but only cisco 2950 switches has the problem of ping timeout or reply time is too long(average more than 2 sec). It will cause I Network Mangement software alarm always.
View 4 Replies View RelatedI have been searching the message boards and wasn't having much luck. I am running some monitoring sessions on my 6509 and on the VLAN I am monitoring, I am experiencing a really large packet loss. If we hook up a laptop to the destination port and run wireshark we are seeing between 80% and 90% packet loss. I dont see the packet loss on the show port command, but I do on the show int vlan command.
The config is as follows:
Session 2

I was doing some reading on Egress vs Ingress and I am wondering if the Egress SPAN replication state could be causing the packet loss that we are seeing or does the ingress & learn command override that?
We are receiving a large amount of output drops on 4 interfaces that connect to microwave wireless.This is playing up with our Management system.
