I've bought a new Cisco 886VA and want to set the noise-margin value. With my old 876 I had to set "service internal" and then I was able to configure the value unter ATM inter config.
But with the new 886VA I can't find a way to configure it.
Comparing my brand new linksys x3000 (Firmware Version:v1.0.03) with my old zyxel p660hw I see that the linksys is running a downstream noise margin of 8.2dB while the old zyxel is running a downstream noise margin of 15dB. Needless to say, I am very disappointed. why the linksys value should be so much lower?
View 5 Replies View RelatedI've got a new Cisco srp527w-u router which is working fine though it's syncing at a lower rate than my Billion (6mbps vs. 8.5 mbps for the billion on the same line). I had tweaked the billion way back to connect with a 4db SNR margin and almost certainly this is why it achieves the higher rate (by comparison the cisco is syncing with an snr margin of 12db). Is there some way that I can configure it to use a lower SNR margin? I realize this might reduce connection stability but I'd at least like to be able to give it a try if possible.
View 2 Replies View Relatedi used a Cisco 886VA with Annex-B service in Germany. Now the provider has changed the DSLAM port to Annex-J but the router does not get any connection anymore.
As per Cisco homepage [URL] the router should support Annex-J in table 7:
Cisco 886VA: Optimized for Annex B; also compatible with Annex J
How to bring up the router with Annex-J service?? Is there something special i have to configure? Do i have to buy Cisco 886VA-J???

I will install in the next days a 886VA router (VDSL over ISDN using PPoE). Since I have no possibility to verify the VDSL config, this is what i prepared. Is this config OK (only VDSL part) ?
controller vdsl 0
operating mode auto
interface Ethernet0
[ code]...
For VDSL over ISDN the interface Ethernet0 must be used instead of ATM . Is this config correct ?
I'm using a Cisco 886VA connected to an ADSL2+ line. Typing "sh control vdsl 0 | inc Err" shows me the CRC errors on the line, but the CRC error counter displayed with "sh int atm 0" is empty. Also with 876 typing "sh dsl int atm 0" I can see growing error rate but "sh int atm 0" is empty.
I want to write an applet to reset the interface/controller if threshold is too high but the event interface detector won't see any errors.
I'm trying to configure multicast between 2 VLANs on a Cisco 886VA running IOS 15.2 (3) T1 (advanced security). While I can set the global "ip multicast-routing" I cannot "ip pim sparse-mode" on my interfaces - ip pim is actually unknown and also doesn't appear in the interface's ip subcommand list when using "?".
The feature navigator says pim is supported on my platform and IOS version.
My config looks like this:
interface FastEthernet3
switchport access vlan 103
no ip address

Is there a way to find in a remote branch the adsl line number in a cisco router 886VA.
When giving show controllers vdsl 0
we can see the upload/download speed but there is no information about the line number. We need this information in order to troubleshoot adsl line problems with our ISP's in remote branch offices.
I want to dumb down a Cisco 886va to act as a pure vdsl bridge modem with a local ip to be able to do some admin work on the router. To some extent my config works, but i think the default vlan 1 kills my internet. When i connect the 88va the vlan bridge 7 and 8 goes up, the router behind connects via pppoe on vlan 7 but no traffic is going through. vlan 8 gets a dhcp lease for iptv and if i don´t switch the receiver on and off the traffic flows and the tv works. I am also able to connect to the local ip to access the web interface. [code]

We all know you can't manage data traffic on the internet since your not in control of both sides of the link. So only queuing would not be a good practice IMHO. I was thinking on just rate-limit or police data-traffic so Voice always has bandwidth available when needed. I've did tried to rate-limit on the ATM0 interface, but no luck. Voice was still very bad.
My question is: where to rate-limit the data traffic? On the VLAN interface, the ATM interface, DIALER interface?
I am configuring ISDN Interface on 2 Cisco 886VA Version 15.2(3)T . I am unable to set ppp multilink on the BRI0 interface and on the dialer interface. It's like the command doen't exist anymore.How can I fix that so that i can have 128 K bandwidth between ma 2 sites ?.

View 8 Replies View RelatedI have just replaced my 54Mbps Wireless-G router (Sky Broadband/Netgear - black, looks like a SkyHD box) with a 300Mbps Wireless-N TP-Link TD-W8960N router, I have also upgraded the the standard 3dBi antennas with a pair of TP-Link ANT2408CL 8dBi high-gain anetnnas.
However when using various WiFi analysis apps I'm getting a signal strength averaging -35dBm and noise of -96dBm when in the same room as the router. But the main bit confusing me is that this is in ALL configurations - with my old Wireless-G router, with the new Wireless-N w/ 3dBi antennas, and with the new Wireless-N w/ 8dBi antennas.
Am I misunderstanding the signal/noise thing or is this Wireless-N router not giving me a better signal at all? I plan on installing an identical setup in a property with patchy Wireless-G coverage next week and I was hoping this exact kit would be the solution.I have tested with two laptops and I am getting 130Mbps link with both, but I understand this is typical of laptop hardware. I don't have any devices with a certified 300Mbps card installed to test with.
So this problem seemed to come out of nowhere, I have no idea why it started. Basically, when I use my internet, eg: opening link, loading video or downloading randomly my speakers make a grinding noise and until the noise stops (can be 1-10 seconds) my internet drops (the internet icon on the bottom right shows it is still connected but nothing loads until the noise stops. Even then, the noise can drop in and out like 10 times in a minute and is constantly messing up the internet.
my speakers are Logitech (doubt that makes much difference as I doubt the problem is linked to them and my LAN card is some Ralink thing, nothing special. Here is a low volume recording of the noise, turn up your speakers to hear it well.
This has been driving me absolutely crazy but I am glad to have found the source of it. Over the past 4-5 weeks ever since i built my new computer, my computer has always had this wierd high pitch noise. I dont know if its coil whine or not, but the sound signature is def not the same as the coil whine that comes from my 7970 card. It sounds more digital.
What could be the cause of this? And what would the remedy be? My ethernet cable is approx 60 ft so it will be a pain in the ass to replace. Or buy another NIC?
edit: forgot to mention....the noise is constant. Not intermittent with usage. No amount of load or idle on the network changes the noise.
Just a sanity check, but setting up NTP authetication on our switches to sync with our Core first, then our NTP server that the Core syncs to second.

Currently we are using a Windows 2003 Server with VPN Sever Role for VPN Access and my users use the built in VPN connection with Windows client. In the past few weeks we upgraded our router/firewall to CISCO ASA5510.
My understanding is that I get 1 or 2 VPN licenses with the Cisco ASA5510 and I would like to configure to test Cisco VPN access. My first question…when I configure the Cisco ASA5510 for VPN (Clientless or via Client), do I need to point the Cisco to my Windows 2003 Server with VPN role on it or the Cisco ASA5510 handles the VPN connection and access?
I am wanting to set up a WAN linkining it to 2 LANs, I was wondering what hardware and software (security etc.) is needed.

View 3 Replies View RelatedI was trying to get Netflow setup on one of my 7K VDCs and ran into a problem. While netflow data was reaching the collector, IP src/dst information was not appearing in the analyzer tool. I could not see any information about conversations. So I contacted the company that makes the collector/analyzer and the directed me to a blog on their site and told me to setup the 7K exactly as it is described in the blog post. I did and a bit later the ip src/dst address information appeared. So the only difference between the two configurations was that in the first case I tried to define a record and in the second case, no record was defined and instead the orginial-netflow parameter was used in the "flow monitor" section. [code]
I referenced the document "Cisco Nexus 7000 Series NX-OS System Management Configuration Guide,Release 6.x", Chapter 19 - Configuring NetFlow.It's clear to me that I didn't do something right in defining my own record since that's really the only difference between the config that worked vs the config that didn't. However, the documentation I referenced doesn't really provide useful information about how to create a record (above and beyond what I can already see by typing '?' at the CLI).
For example, the "match" command makes no sense to me. Usually when you have a match command it is accompanied by some sort of ACL. In the "flow record" section a match command would be something like "match ipv4 source address" but that's it. What does that mean? Match anything that has a IPv4 source address?? That doesn't make much sense. The collect commands are equally as bewildering. If I want to define my own record (and not use the original-netflow parameter) what do I need to do in the "flow record" sub-configuration to get Nexus to send ip src/dst information to the collector (which, I would think, is basic information to send - what good is netflow data without it)?
