Cisco Switching/Routing :: 4900M WS-X4908-10G-RJ45 Port Startup Delay
Mar 4, 2013We have recently purchased 2 x 4900M switches with the following configuration:
2 x X2-10GB-SR installed in port te1/1, 1/2 (optical)
1 x 20 x 1GB RJ45 installed in the top left of chasis ge2/1 - 2/20
1 x WS-X4908-10G-RJ45 8 port 1/2 card in the top right of chassis te3/1 - 3/8
We have te1/1 connecting the 2 switches, and various vlan's and connections on the 1GB RJ45's with no problems.
However, we have a number of 10Gbps BaseT connections te3/1 - te3/5 which are causing us issues. On a reload of the switch or removal / re-install of the cable it can take anywhere up to an hour for the port to become active again. So when we reload the switch, we may get a connection come up after say 3 mins, but the port next to it may not come up for 15-60 min. The cabling is all the same (CAT6 and has been tested/verified) and all connections go to Broadcom 10Gb cards in Dell 820 servers running vmware. We have the following set on the ports:
switchport mode access
spanning-tree portfast
No speed or duplex can be set on these ports - these options are not available in the config.
Once a link is finally established, it will hold the link solid with no problems, but this is a problem for us, we can't have a reboot take an undetermined amount of time for the link to come back.
Cisco Switching/Routing :: 3750 Switch - ICMP Delay To Default Gateway
Aug 25, 2012I had setup a lan infrastructure with 5 3750 stack swithes. In these 3 of them are in one stack which is acting as access switch, 2 of them in another stack which is as core switch where all the SVI is configured. Now, when i tried to ping from our edge pc which is connected in access switch to default gaeway, which is configured in core switch, the ICMP is getting delayed . But when try to ping from the same edge pc to another user PC, it is getting less tahn 1 millisecond icmp replies.
why icmp is delaying to default gateway , but working with another edge to edge pcs without any delays?
Cisco Switching/Routing :: Catalyst 3750-x Icmp Delay To Default Gateway?
Sep 10, 2012i am facing a problem when the client vlan is commmunicating with the default gateway on the core 3750-x.
ios in 3750-x core is 3750e-universalk9-mz.150-2.SE.bin. But, client to client communication is happening without any dealy and icmp is less than 1 ms always.
When try to ping default gateway of client vlan, it is getting delayed (variable icmp delays). Is this an ios bug?
Delay With VOIP Calls?
Jan 24, 2011I am encountering delays when making any calls using VOIP. I understand that there is always a delay using VOIP but not as much. I've done a bandwidth test on my network and everything seems to be Ok, we have 4 T1s with 55 Reps using it. There is nothing choking up the network.
View 3 Replies View Related5-10 Second Delay Before Loading Of Webpages
Sep 17, 2011I've got a strange problem with my internet connection. I have recently moved and brought my desktop with me. While I am able to connect to the internet in my new place, a weird problem arises: whenever I try to access a new webpage, there is a consistent 5-10 seconds delay before the page actually loads. After the initial delay however, the webpage will load quickly. This problem will repeat itself whenever I try to access a site that is not cached. I have tried switching ethernet cables/wireless adaptars and this problem persists. I have also tried scanning and cleaning my computer yet nothing works. Speedtest.net show that my ping, d/l and upload speed are all fine.
PS: Just to add some information, my new place comes with its own existing router (the building includes internet into its rent), and I am simply plugging an ethernet cable from my computer to it. In addition, my roomates and my laptop seem to be able to access the itnernet fine with this problem. Since this sounds a lot like a DNS problem, I have also tried using OpenDNS and that doesn't work either. In addition, the delay persists regardless whether I am trying to access a website via its domain name or numerical IP address.

Jul 2, 2012I have Cisco Catalyst 6500 with IOS Version 12.2(17r)SX5I need real-time monitornig of failed interface, to shut it administratively down and after 5 minutes "no shutdown" it.I think is good idea to use Cisco EEM for this task.My algorithm is below:
1. EEM script is looking for event about failed interface.
2. EEM script is shutting interface down.
3. EEM script is waiting 5 minutes.
4. EEM script is enabling interface.
I know how to configure EEM for steps 1, 2 and 4, but step 3 I do not.
Produce Time Delay On Optical Link?
Feb 27, 2011Is there a device, which is able to produce a time delay on fiber optical link? I mean for example if one would like to reduce the power level of an optical signal, he could use simple air-gap optical attenuator on optical link. However, has somebody seen a device, which is able to introduce a time delay on optical link?

Apr 23, 2013Any good way to force a serial link to delay packets to simulate a hi latency WAN link? Found this command so far:
Router(config-if)# transmitter-delay hdlc-flags
I can dial the speed up/down via clock rate all good but I need to also simulate latency. This is for simulating a WAN bonding scenario so I was going to aggregate a 10M ethernet port with a 2M serial and a 512k serial. But I need to also ensure varying latency.
Linksys 3200 - Router Delay / Lag During Gaming?
Jul 4, 2011I noted that my router (Linksys3200) has delays or lag on the average of 5 to 10 seconds apart, but random, while playing on line games. While continuously monitoring delays (ping) with a program called Ping Plotter, it ranges from 25ms to 65ms. When not gaming, just surfing the net, the ping is zero and once in a great while a 5ms or 6ms spike may occur.
Am I looking at a malfunction in the router or the computer? or Is this normal?
Small Delay When Browsing Shared Folders
Jun 26, 2011I have a fairly new HP Proliant server that serves as a fileserver, among other things. I've tried serveral operative systems in order to find the one that suits my server-needs best and ended up with Windows 2003 Server.When browsing shares on my server over local network, there is a slight delay on approximately half a second every time I navigate. It's not a huge problem but it's enough to be annoying.However, there was no problem when I tried Debian 6 with Samba. So logic would suggest the problem is somewhere in a setting or something like that. But which setting? [code]

Apr 15, 2012Actually i have problem with my connection and i would like to find that problem. i have 3 sites(1,2,3) connected together through fiber multi mode cable. The site 1 having the control room, the maximum distance between site (1 and 3) is 1.8 Km, the other distance(1 and 2) is 1.2 km and i already used 3750X switch and GIBIC GLC-FE 100Fx with support MM cable up to 2 KM.
i have in site (2 and 3) 10 cctv 3 mega pixel cameras and i check for the bandwidth is less than 100Mbps when i connected the 2 switches(2 and 3)to the switch in the site 1 there is a delay i thought maybe because of the bandwidth so i tried to connect only 1 camera but the same problem(delay). i did not make any configuration for the switches.
Time Outs On LAN - VoIP Phones Have A Delay Internally?
Oct 6, 2011A couple of users on my network complain about timeouts. They access the same server which runs a SQL server. People from outside world can access it without a problem but internally it keeps timing out. I have also noticed that VoIP phones have a delay internally. So if i pickup my phone and dial an extension the other person can't hear me sometimes but i can hear him.
I have experienced the VoIP problem but have never had any time outs on my machine. I tried packet capture on a couple of computers but i cant see anything out of the ordinary. Alot of ARP, some STP which i think shouldn't reach the machines, dropbox traffic etc.
Cisco Routers :: 2 Seconds Delay On SRP527w FXS Port?
Nov 6, 2011I have a wierd "2 second delay" issue with audio generation on a SRP527w.When in a call, with myself on both ends of the setup DECTphone - FXSport on SRP527w - VOIPprovider <> PSTN/GSM - Mobile I can hear my voice on the mobile immediately, as expected. However, the same words i speak (having both the DECT and the Mobile at my ears), are heared on the DECT with 2 seconds delay. Trust me when I say that this is the base for a poor rated telephone call and misunderstandings therein.
This issue is the same when calling to other mobiles and even land-lines, both in being called and being the calling party... Every time the voice from the other side is heard "delayed" on the DECT. Testing the DECT on a normal non-voip connection results in a normal conversation, as far as this is possible with me talking to myself I do have a separate CBR pvc for the voice on the SRP and to investigate the issue I've put the SIP user on a soft client, using a UBR pvc on the same SRP, both pvc's do use the same provider but diverend gateways. And with the UBR + softphone i do not have this "2sec delay" issue.
So, ruffly said this seems to locate the issue in the SIP>FXS DSP, with specific only the digital>analog decoding/generation (not with the analog>digital encoding, as i hear myself normally on the mobile, with no/normal msecs delay).
D-Link DCS-930L :: Motion Detection Lag Or Delay Until Image Emailed?
Nov 21, 2011I am using my new DCS-930L to monitor motion at a door entrance. It is firing off when motion happens but the image it emails is taken @ 12 seconds after the motion. So the result is I know motion happened but the person who came to the door is long gone or through the door by the time the image snapshot is taken. I get multiple emails containing images of the empty entrance. Is this a software, hardware, firmware or user error issue?

Cisco :: Serialization Delay From The Wire / Interface Onto Router / Switch Backplane / Fabric?
Feb 28, 2013So the delay is introduced getting data onto the wire. However say there are two hops to the destination server, each hop is via equal connectivity speeds say 1G interlinks.
Question:
Is there serialization delay FROM the wire/interface onto router/switch backplane/fabric?
Is the serialization delay from backplace/nic back onto the wire to the next hop? - Or if using a switch with equal in/output speed transmitted without serialization?
What happens with a routed interface vs switched?
Most articles discuss the latency induced between the much higher OS/NIC interface out to the wire, but not the switch/router serialization that does or doesn't occur.
Linksys Wireless Router :: Weird Random Delay Accessing Websites With E4200?
Jul 25, 2012I just got an e4200 refurbed router, and it's been working great except for one problem I'm having. I have Comcast cable with Ubee D3.0 modem. For some reason, there will be a random 4-8 second delay when going to certain websites. While this normally wouldn't be a problem, it occurs quite frequently with Google.com and we definitely can't have that. I've updated to latest firmware. Ran ping test to find optimal MTU, went with 1500. To be sure it isn't a DNS issue, tried accessing Google by IP addy and getting the same delay. The delay seems to occasionally occur with Facebook as well, at one point I couldn't even get to Facebook and had to release/renew ipconfig. I have Mac address cloned if that makes a difference.

Cisco Switching/Routing :: Catalyst 4506 / Routing For Internal And Guest Network
Dec 19, 2011I am implementing a guest wireless network to work alongside my internal network. The guest network will use the existing switching network and will be separated by VLANs. I have the ASA set so that traffic can get to it and out to the Internet. I can set up a workstation on the same VLAN as my guest network and can route inside my network (strictly doing this for testing purposes). Where I am having problems is with the Catalyst 4506 switches and the ip routing. I had two separate "ip route" statements defined on my switches.
ip route 10.200.2.0 255.255.255.0 10.200.2.254
ip route 0.0.0.0 0.0.0.0 10.100.100.254
I have discovered that the traffic is always following the default route despite the fact that my IP address on my test workstation falls in the 10.200.2.x network. I was looking at documentation and found that it is possible to set up policy-based routing on the core switches. Can you have two "ip route" statements defined like this to segreate traffic or do I have to use PBR for routing (or a combination) in this case? If I define PBR then how does that impact my existing routing? I need to make sure that I can still route the existing traffic while I'm configuring this change.
