Cisco WAN :: 7206VXR - GRE Tunnel Transmit Bandwidth
May 19, 2011
We have a major poblem going on with our VPN router.We have a 7206vxr router which has an mGRE tunnel forming EIGRP neighbourship with about 800 remote locations using GRE over IPsec.
We have a problem where the EIGRP neighbourship keeps flapping intermittently and this happens to 30-40 locations at one time and very frequently.What I noticed was that the GRE tunnel transmit bandwidth was showing as 8 Mbps. I guess there is an option to change it.Will this 8 Mbps limit cause any issues of EIGRP neighbourship flaps and will increasing the bandwidth useful.
We are also seeing output drops on the tunnel interface.

We have point to point metro ether net link terminating on 7204VXR router.On this point to point link we are configuring GRE over ip sec. Problem is when the traffic exceeding 8mbps we started getting packet drops. from the Cisco documentation it seems the tunnel bandwidth is by default 8mbps and there is parameter like Inherit/receive but those actually not change the tunnel interface bandwidth.If we just give tunnel bandwidth with bandwidth mentioned it allows me to give option of 100mbps but again the tunnel interface bandwidth remains 8mbpos only and probably that 100mbps is useful only for routing decisions.
i am using advance security 12.4.15T12 image. Whether this is a limitation or any other way to go beyond 8mbps for the tunnel interface (7204VXR-NPEG1 processor)

We have two Cisco 2811 Routers setup with a GRE tunnel that we would like to constrain the bandwidth on to replicate a satellite connectinon of 400 kbits. We tried the bandwidth command 400, but from what I understand that is only for routing metrics and not actual speed of the interface.

I have a Cisco 1941 router with the Security license running IOS c1900-universalk9-mz.SPA.151-4.M.bin. Is there a "tunnel bandwidth" command like with routers that have the Advanced IP Services license? My concern is being able to adjust the bandwidth to a value greater than 8 Mbps...

I'm looking at the spec sheet comparing Cisco WLCs and I see that the 2504 has a bandwidth max of 500mbps. Just to be clear, not all of the traffic from the APs goes through the WLC does it? In this setup, the APs would be plugged into a PoE switch as well as the WLC. The only traffic to WLC would be the CAPWAP tunnel, CleanAir info, etc right? All other traffic should just be handeld at the switch right?Also, does the 2504 licencing include CleanAir in the price?

We have a Cisco ASA 5520 supporting multiple VPNs - both remote-access and Lan-to-Lan. We would like to monitor the bandwidth utilization of the IPSec Lan-to-Lan tunnels.

So in our DMVPN network, we have this Cisco 3845 hub router that is connected via a DS3 to the Internet, and our spoke sites usually have a broadband connection that typically have a maximum of 1Mbps upload capacity. We are getting ready to add a few more sites to our network that are connected to the Internet with 10Mbps upload speeds (and 50Mbps download). Spoke site routers are usually 800 series ISRs. We have seen spikes of 8-10Mbps on the hub router so far. So the question is that a site with 10Mbps upload speed transmit to the full capacity over a DMVPN tunnel or is it limited by other factors? What are those factors?

I have some challenges with a VPN config I recently setup for a client.I have at the HO the following:
- 1800 router
- Avaya phones and Gateway
- 1MB radio internet access
At the BO(branch office), i have:
- 871 Router
- Avaya phones
- 256k internet bandwidth
The only reason we setup the VPN in the first place was for the phones at the BO to be able to connect to the gateway at the HO and also able to make calls and receive calls as if the phones were at the HO.The phones at the BO successfully register to the HO, but are unable to recieve calls and dial out. Everytime I try to make a call, the phone displays a "connecting..." message. [code]

I've got an ASUS G50V that I normally connect to the net through a wireless router but I recently bought a router so I can make a physical connection and increase speed. However I cant get it to connect to the router no matter what I do (i had it working for a few hours at one point but it dropped off again).I confirmed it wasnt the router but running a crossover cable from the laptop to my desktop, setting static ips on both. Now I can ping the laptop from my desktop but for some reason I cannot ping the desktop from the lappy. I've tried everything I can think of but no dice.

I recently bought a Nintendo 3DS but unfortunately my University's wireless security (WPA2 Enterprise) is incompatible with the system. As such, I was looking for a way to transmit a wireless signal from my computer, and place an alternative form of security onto it (such as WEP), so that the 3DS can connect to it.
At the moment, my desktop is connected via ethernet cable, which plugs directly into a wall socket. I'm pretty unsure as to what to use, I've heard of things such as 'wireless bridges', but I'm not sure how they work. Also, I'm looking for the device to transmit a signal even if my desktop isn't turned on. Is a router my only option?

I have a client(C) and a server(S) nodes plus an intermediate node(I). Each node has a public IP. What I want to do is to transmit some data(whatever) from C to S but this data to go through I. So C ---> S will become C ----> I ----> S. I read something to create a tunnel(ip add tunnel) between C and I and add a route between them ? I tried different examples but did not work at all.

With firmware 2.06 my DIR-600 had transmit power choices 100%, 50%, 25% and 12,5%.(even 12,5% gave me excellent strength on all my devices, what is really the difference)But after updating to firmware 2.11 (via 2.10, othervise my DIR-600 refused to use 2.11)the choices for transmit power is now only "High", "Medium" and "Low". know the percentage values for those three settings?

I will be doing a site survey using the client's Cisco 1262 with only 1 radio (g/n), 3 antennas. What is the maximum transmit power, 20dBm or 23dBm? I need to set the transmit power in the Airmagnet to 50% or 3dBm down as recommended by Cisco.

I upgraded my 3602i survey ap the other day to the public image the other day and I have to say.. I've got it up and going of course, but I have a concern on the transmit power settings. Originally, the only option it gave me was MAX and -4, which I hadn't seen before, interesting.. -4 of what? 20? 17 probably or I though? At any rate, I went into the CLI to set the power manually, no issues there, though my options are not what I expected, maxing out at 25mw basically, which is fine but.. in setting it manually in CLI, the web interface reports an Error on transmit power. So.. does this work or not? Any survey with this image to verify it's power settings? 15.2(23c)

I had a requirement where I have to send the internet connection over 100m.As Ethernet supports clear transmission only upto 100m, I came up with this new idea (only in papers untill now). I believe RJ11 cables (normal telephone line) would be able to carry signals over longer distance as in ADSL broadband. plug the Ethernet cable which is already connected to internet source into ADSL modem. This ADSL modem will be connected to another ADSL modem which is at a longer distance away(let us say more than 100m or so.) The output of the latter ADSL modem will be connected to a computer/router which requires an internet connection.

Which transmit hash policies are supported by the SLM2008? I can't find this information in any of the documentation for this switch, all that is stated is that it supports Link Aggregation using IEEE 802.3ad LACP. I'm connecting to a Netgear ReadyNAS Pro that supports Layer 2 and Layer 3+4 transmit hash policies and I'm not sure which to choose (or whether it matters).

We have a Cisco 6513 Switch. During some parts of the day it is having large amounts of transmit discards on a certain interface because of the amount of data we are pushing. We have determined it is a link problem and not a problem with the switch. The link cannot handle the amount of packets the switch is pushing out. I was wondering if there is a way to create a buffer or a way to regulate the maximum amount of packets that can leave that interface without losing any packets?

Cisco 4500-X do not support egress queing on VLAN interfaces (SVI) which means cannot do a traffic-shapping, is there a work around via policing? I can police the traffic and then on the trunk interfaces do "per-port-per-VLAN" QoS but again only the policing not shapping so I was wondering what is the effect of "exceed-action transmit" command
policy-map SHAPE
class class-default
shape-average 8000000

I have an AP1242 near a couple of conference rooms. I get complaints when we have a large contingent in there and some try to download documents. The bandwidth consumption is meage - less than 2Mbps. But there could be say 50 people in those training rooms. I see no errors at the FE interface on the AP but I do see a good number of Transmit Discards.
Are 50 users connected to an AP1242 simply more than should be expected of the device? 802.11g is the radio.
Are transmit discards indicative of some kind of configuration problem? The users in these cases are generally very close to the access point - within a few feet even.
If it is indicative of a configuration problem would that be an issue of the configuration of the laptop wifi cards or a problem at the AP?

After opening up Solarwinds NPM, I noticed that a few of my interfaces had lots of discards (who knows how long it's been sets the counters were reset)
interface GigabitEthernet1/0/25description Etherchannel to MamaCassswitchport trunk encapsulation dot1qswitchport mode trunkswitchport nonegotiatepriority-queue outchannel-group 4 mode on
interface GigabitEthernet2/0/25description Etherchannel to MamaCassswitchport trunk encapsulation dot1qswitchport mode trunkswitchport nonegotiatepriority-queue outchannel-group 4 mode on
interface Port-channel4switchport trunk encapsulation dot1qswitchport mode trunkswitchport nonegotiate,It looks as if priority-queue was configured outbound on these interfaces, could this be the cause of the transmit discards which are now up to 79,835, I just reset the counters on the interfaces a little while ago.
I'm not the best in the world when it comes to QoS, we do have some VoIP phones, but they are only a specific network, and do not travel outside, since there are used mainly for VoIP training. I do know both interfaces are running the default of FIFO.

We have a 7206VXR with an NPE-G1 processor. We're running the standard stuff on it, but here are the highlights.We just enabled netflow on it to send the data to an external source for analysis and the overall CPU level increased, but not significantly. About what should we expect for the overall CPU level? At this point, it's averaging close to 40% during peak hours.
