Cisco Switching/Routing :: 6509 LAN Is Set Up With Default VTP Settings
Dec 2, 2012
my LAN is set up with default VTP settings
-core switch cisco 6509 vtp server
-access switches 2960 vtp server
-no vtp domain set on any switches
-no vtp password set
untill now i manually set the vlans on switches (didnt see anything automatic created on switches)is there any danger with the above settings , that a switch with domain name set and higher revision numberwill delete my vlan settings? if yes how can i protect/disable vtp in my LAN

One of our costomers has a SRW224G4 Switch - which has not any documentation :-(
I do not get onto the switch in any way. I do not have an IP-Address, the default settings for he serial port do not work ... So I cannot reach the device and reset the password like described in: [URL]
Is there any other way to reset the device? I cannot find any reset button.

I have two ISPs. Each is on it's own subnet connected to the 6509 MSFC/Switch. FW1 is on 100.1.100.0/30 and FW2 is on 200.1.200.0/30 subnet. My goal is route all traffice going to the Internet from subnet 10.133.3.0/24 to FW1 and all other subnets across the organization to FW2. I am not sure if I need to use ACL / Static route combo, or just a static routes or ACLS?

I was looking at a problem where a traffic from certain sites have a restricted bandwidth, an ongoing problem for a year or so, apparently this throughput never exceeds around 25Mbps. My customer describes a situation where the end to end utilisation rises, eventually flat-lining at around 25Mbps. how many extra systems come on line, this traffic never exceeds this rate, and end users complain of poor responses.
During my investigation I found that one of the switches (Cat 6509) in the traffic path has a policer configured on a vlan interface, the policer has 3 sections for different traffic based on DSCP markers, and a default (unconfigured) class-default. Various people have had a poke about with this config over the years, with the result that all the traffic has the CoS and DSCP tags set to 0. All this traffic is hitting the class-default in the policer.The link that this traffic hits the Cat 6509 on is a 100Mbps link.
If I was designing this from scratch I'd probably configure a rate for the class-default.my question is, in the case where no specific configuration has been entered for the class-default, how much bandwidth is allocated to this class?

Right now I have 2 default routes load balancing 100MB internet links. This is on my 2 6509's.
ip route 0.0.0.0 0.0.0.0 10.47.2.1 (FWSM)
ip route 0.0.0.0 0.0.0.0 10.47.2.250 (5510)
Is there anyway to make the first default route take more of the traffic, like 60/40 or 70/30?Any program that I could use to see top users going through the FWSM?

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.

We have a 6509 series of core switches and 3750 series of L2 switches, There is no default gateway or any static routes to any IP.VLAN 1 is made admin down and another vlan is used for all communication here in this environment
Attached is configuration for reference But still I am able to take telnet or SSH. I want to know how telnet or SSH or tacacs authentication happens without any static or default route.

First time on this forum: I have a client running a Windows 2008 server, Windows 7 OS. We set the default printer as the server file cabinet printer, however, between logging off in the evening and back on in the morning the default printer switches to his local printer

I have a question about filtering incoming bgp route updates from an internet provider. This provider sends the full internet routing table and default route and on an incoming prefix-filter on the customer switch (C6509-sup720) the default route is only accepted.What happens on the 6509 switch when the BGP peer flaps?Does it need to process all the internet routing updates, and if yes probably it cannot handle all these updates?What happens with the CEF table, will the switch install the routes first?

We need to "reset" a SG200-08P switch back to the factory default settings and noted the "Quick Start Guide" implies the "Reset" button next to the power button doesn't exist and refers the user to the "Cisco Small Business Smart Switch Administration Guide" for instructions. We couldn't find any information related to a "factory reset" in that document either. Pressed the "paper clip button" on the switch but we still can't get in.

I have 2 WRVS4400N routers that were installed at 2 remote locations to provide VPN access to these sites. The routers have been found reset to the factory defaults on three occasions, twice on one of them and once on the other. Both sites are unmanned so no-one is on site to have pressed the reset button, and both routers were set to have remote management disabled. They are running v2013 firmware.

What would cause my Dir-825 to magically revert to it's default settings? This is the 4th time this has happened.We rely on a Verizon Network Extender for phone service. It requires an internet connection to function. When the router brain-farts, we don't have phone service... and we don't know it until we try to call out, or try to use the internet. We went to bed last night with the router working and woke up to it not working. It's just my wife and I here. I haven't seen the dog showing any interest in jacking with our computer gear.
When I access the setup utility and go to Manual Wireless Network Setup, the Wireless Network Name has defaulted to dlink, and Security Mode is None. I have to re-enter my personalized setup info, (because that is what our computers are looking for), then all works fine again.I'm a savy XP user, my wife has Vista (yuk) (she doesn't know any better; her daughter installed it).We are Comcast customers. We own a Linksys CM-100 modem. (When I connect direct by hardwire, (i.e. bypass the Dir-825 router), from the modem to any computer, or the Verizon Network Extender, they function just fine. Setup utility for Dir-825 says we have Hardware Version B-1; Firmware Version 2.02NA.
Set Firewall settings to Endpoint Independent for TCP and UDP. I see other posts addressing similar issues of reversion to default settings... but there don't seem to be any clear resolutions of these issues. On 2010-03-11, gunrunnerjohn posted, "I think there may be a shadow file that's actually in the FLASH that needs to get written back to make the changes stick. I seem to recall there is a command to sync the RAMDISK copies to the FLASH." Yet there is no more to this thread.

Recently purchased a RVS4000 Router, which included v1.1.14 firmware. Is it necessary to reset the router to Factory Default settings, after upgrading to v1.2.11, as in most of the other previous upgrades?

I currently have this router in use with verizon dsl (PPPoe) setup.I have this set to "always on". Since the verizon modem, which is also router has been set into bridge mode and the d-link came into play its been extremely slow, and dropping connection. The router is in a separate IP class, and has no conflict with the modem. My question is, if I upgrade this firmware from 1.0 to 1.02 will it default to factory settings? I know it says only some will. I do have the backup config file, but i would be doing this remotely, and would not be able to get to this router if it goes down. Has anyone gone from 1.0 to 1.2 and saw a difference and speed, and are you able to do this without losing settings.

we've had an issue with our network, we have 2 6509 connected with redundancy, which are connected with 2 x 4900 Switches, from which are connected to a ESX Chassis for visualization, the thing is that the ESX stopped working, and the 4900 switches, and the main core were suffering from overload, they hang on it very well, in order to stop the overload, one of the links to the ESX Chassis were disconnected from one of the 4900 switches. The CPU usage from the 4900 and the core(6509) went down below 40%, and then they started to migrate the virtual servers from the chassis to another 2 chassis that were added right after. They were actually working well, but suddenly the 6509 changed to the other supervisor after everything was OK. We were wondering what could have been the cause of this, maybe the virtual servers migrations, maybe the overload from the ESX ? We also had a few question, is there any need to reload the cores every few months as a planned task ? Because the cores have been up for more than 1 year. And also is there any kind of of tool to monitor the CPU status, or the status overall from the cores or the switches ?

The have around 80 staff and I think the current infrastructure is overkill for the size of the company. The current kit is old and they have no GB ethernet ports. They currently have:-
Core Switch:
1x Cisco c6509with a 48 port fast ethernet module (WS-X6248-RJ-45)
and an 8 port fibre module (WS-X6408A-GBIC)
I'm looking to replace this with something with 72 ethernet ports and 8 fibre ports
Access Switches:
2x 3500Replacement needs at least 48 ports and 2 fibre modules each
and 2x 5500Replacement needs at least 72 ports and 2 fibre modules each.

If client gateway = 192.168.64.9 then next-hop = 192.168.64.8 else use default-route 0.0.0.0
I know it's possible to do a route-map match ip-address ACL list. But is it possible to match on gateway?
Some info about hardware and config:
6509-E in VSS (IOS 12.2(17r)SX5) withVS-S720-10G supervisor.
All routes are static, IP for 192.168.64.9 is on SVI vlan.

I have a 1941 router configured for Policy based routing with two ISPs.Two static default routes configured to point the gateways of respoective ISPs with same metric.But the problem is, packets are going throug the one ISP only while doing traceroute.
N/W connectivity:
ISP1-----> <----------------------> LAN1
| Router |

I had something strange happen to my WRVS440N router yesterday. Our network had crashed for some reason. So I attempted to log into the device to see what was wrong and I was surprised to discover that all of the settings including user name and password had reverted back to factory default.
1. What are all of the possible scenarios that would cause this to happen?
2.Would disconnecting power in the middle of a boot up sequence cause the router to revert to factory settings?

My router automatically sets the wireless network settings to the original default. Sometimes after 1 hour sometimes after a week. It resets to automatic instead of the manulal settings I use for configuration. Changes the SSID to Linksys and disables wireless security.

I would like to ask you if it's possibile to block routing between some Vlan for just once of them.
Maybe I can explain better:
I've got a Cisco 6509 with 4 configured vlan interfaces
Int Vlan 10 10.10.1.0/24
Int Vlan 20 10.10.2.0/24
Int Vlan 30 10.10.3.0/24
Int Vlan 40 10.10.4.0/24
Vlan "10" is the phone voip Vlan and it must not talk with the others Vlan. The others Vlan can comunicate normally except with Vlan "10".
Pratically Vlan "10" needs to be isolated from the others.
This equirement comes becouse Vlan 10 is wireless and has the WEP key encryption (very weak protocol). Some Phone couldn't support the WPA2 key and I need to avoid an unauthorized external client, cracking the WEP key and connecting to this WiFi, could have free access to the others Vlan.

I have a problem on my catalyst 6509 on which I would like to do the following things :
I have some Vlans in which multicast is enabled.
In tose Vlan theres is a router which is default router for equipements.
I had enabled multicast routing because some Vlan needs to exchange multicast informations, but I wolud like to make difference between Multicast traffic. For example I have 5 vlans:
Vlan 1 and 2 need to exchange Multicast informations but the don't need multicast information from Vlan 3 and 4
Vlan 3 and 5 need to exchange Multicast informations but the don't need multicast information from Vlan 1 and 2
Vlan 5 is independant Vlan but doesn't need to have multicast information from all others vlan.
Last problem, equipement on differents vlan can use the same Mulkticast group address. In this case, Multicast routing is not working between Vlan 1 to Vlan 2 and Vlan 3 to Vlan 4.

We have two catalyst 3560 switches running c3560-ipbasek9-mz.122-58.SE2.bin They are connected using etherchannel using gi 0/21 - 24 interfaces.
on 3560-1 switch, there isn't any ip-default gateway or ip route configured. It only have 1 interface vlan configured.
on 3560-2 switch, there is ip default gateway configured along with 1 interface vlan.
What i dont understand here is that, i can reach out to other subnets from 3560-1 switch in which the routing is not enabled?

So just recently my Internet has been running a lot slower than normal at different times of the day (completely random, could be fine for hours then just turns slow). I know it's not the Internet itself, since it's only happening on my computer, and none others in the house - and I'm far from capped. I've run AVG, Spybot & Malwarebytes' scans and have found no infections of any kind. I've run TCP Optimizer and used the "reset to windows default settings" feature, which also hasn't worked one bit. I've tried different Ethernet cables and different plugs in the modem and no improvement.
