Cisco Switching/Routing :: 861 - Connection Hangs With Vlan Update
May 28, 2012
, I am trying to change the default IP address in vlan 1 on a cisco 861 but everything I do so my connection via SSH hangs and all ssh/telnet attempts are refused.
my commands are as followed:
int vlan 1
ip address 192.168.1.1 255.255.255.0
[hangs]
my current vlan 1 address is 10.10.10.1 255.255.255.0
my vlan1pool on dhcp
is an address range of 192.168.1.0/24
do i need to update something in the authenication to allow connections from 192.168.1.0/24 instead of 10.10.10.0/24

I purchased a WRT160N router last Friday. After setting it up, everything seemed to work fine, but after a couple of hours, the router stopped responding to any requests. The LEDs stayed on as if nothing had happened, but the router was dropping everything coming from both the WAN and a wired LAN interface. Since than, I had to restart it 3 times during the last 3 days.The firmware is 1.53.0, which seems to be the latest firmware for the European market - even when I try to get a newer firmware, this site only offers the US version 1.02.2.Should I update the firmware to the US version 1.02.2 ? Is there any difference between the 1.53.0 and the 1.02.2 version ? Is there a way to restore the original firmware in case the update fails ? I haven't found any link to 1.53.0 version..Also, does this firmware updating affect my warranty ?

I am a complete newbie to Cisco equipment. So far I've been able to figure out how to do most of what I needed by using the ASDM but I have run into something that is a little more complicated that just opening a port. We currently have a connection to our remote site. This site has a T1 internet connection. Our connection is a site to site VPN with an ASA-5510 on this end and a ASA-5505 on the other.
We are upgrading this connection to a 75mbit hybrid microwave/fiber link. The provider is going to hand it off to us as an untagged VLAN. We made the decision to route all of the remote site's internet access through this location as to avoid having to split off part of the bandwidth of this link to dedicate to internet access.........

we're facing a weird issue lately with a Cisco 2821.An interface stops responding after a few hours.The only way to bring it 'up' again is:
Hardcode: duplex or speed
or
shutdown -> no shutdown
there are no errors in the "sho interface" and no errors or entries in the log.
FastEthernet0/0/0 is up, line protocol is up
Hardware is Fast Ethernet, -
Description: Infopoint
MTU 1500 bytes, BW 100000 Kbit/sec, DLY 100 usec,
reliability 255/255, txload 1/255, rxload 1/255

The router had firmware 2.0.x(?) and I tried to update to the latest FW, according to the webpage that's
FW_E1000_2.1.02.006_US_20130115.bin
Hardware is E1000 v2 according to sticker on back.The firmware update failed (no reason given) and the router now hangs in limbo where all it does is flashing the power LED.I set my PC to 19?2.168.1.2 and TFTP'd the firmware over to 192.168.1.1 - no errors reported and 192.168.1.1 is pingable. Held reset for 30s, then powered down the router for another 30s. On power-up the router still flashes the power LED.

I have two networks at two sites with a dot1q trunk between the two L3 switches at both sites (no routers involved)
SITE A - Cisco 3750 L3 - VLAN ID 50
10.10.50.0/24
SITE B - Cisco 3750 L3 - VLAN ID 50
10.20.50.0/24
I would like to extend the SITE A VLAN to SITE B so that I can move hosts from SITE A to SITE B without needing to change their IP address but the vlan ID is already in use. Obviously the easy solution is to change the VLAN ID for one or other of the sites but both sites contain hosts that run 24/7. Is there a way to join two VLANs with different IDs together.So for example I create a new VLAN 60 at SITE B and associate it with VLAN 50 at SITE A.

I have a 3750G switch in my production network that only has VLAN 1 on it. All ports are in a default state and VLAN 1 is disabled. The switch is passing traffic but shouldn't having the default VLAN shut down cause the ports not to pass traffic? If I start to create VLANs will that cause the switch to stop passing traffic?

I am trying to setup a L2tpv3 VLAN-to-VLAN tunnel.My setup has two Cisco 890 router with Cisco IOS Software version 15.0(1) M4. These routers are connected directly on FastEthernet port 8.
One linux machine is connected on FastEthernet port 0 on each router. The two linux machines are on same vlan. I am trying to establish a vlan-to-vlan tunnel between the routers and send traffic between the linux machines.
I followed the case study 11.4 from [URL] and configured the l2tp-class and pseudowire-class. However, the vlan interface configuration is different on 890 router.
I configured a vlan interface as follows.
(config)#vlan 200
(config)# interface FastEthernet 0
#shutdown
#switchport access vlan 200
(config)# interface vlan 200
I don't see the 'xconnect' command in this context. What's wrong with my configuration?

We have a low bandwith (15-20 Mbit/s) to the ASA from our Client vlan. If i connect the Client to the same vlan as the ASA is, the bandwith (90 Mbit/s) is good.
Here are the Layer 3 Design:
Client -> vlan 2 - Switch - vlan 7 -> vlan 1 - ASA 5505 -> ISP
The Layer 2 Design:
Client -> Gig2/0/13 - Switch - Gig4/0/43 -> Eth0/1 ASA5505 -> ISP
IP Address:
Client: 172.16.2.10Vlan2: 172.16.2.1Vlan7: 172.16.7.1ASA: 172.16.7.2
I assuming the switch has a problem with routing ?It is a stacked Switch with following members:
switch 1 provision ws-c3750g-12sswitch 2 provision ws-c3750g-24tsswitch 3 provision ws-c3750g-24tsswitch 4 provision ws-c3750x-48
And we have following error message in the log from the switch:
%PLATFORM_UCAST-4-PREFIX:
One or more specific prefixes could not be programmed into TCAM and are being covered by a less specific prefix, and the packets may be software forwarded I first get the idea that the switch is overloaded with router traffic. Thats why i assuming i have to check the sdm templates, but i'm not sure if this resolves the issue.
Here are the relevant config:
ASA Interface on the Switch:
interface GigabitEthernet4/0/43description ASA-inside LANswitchport access vlan 7switchport mode accessspanning-tree portfast
Client Interface on the Switch:
interface GigabitEthernet3/0/1switchport access vlan 2switchport mode accessswitchport port-securityswitchport port-security aging time 2switchport port-security violation restrictswitchport port-security aging type inactivitymacro description cisco-desktopspanning-tree portfastspanning-tree bpduguard enable

My PC boots fine (via SSD) but as soon as it passes the login screen and brings me to the desktop, the network connection icon has a circle going around it for about 30 seconds. Except the circle isnt moving, or rotating as if it's frozen and when i click on it to go into the network and sharing settings, it hangs. While this happens i can access anything else fine except internet based apps. Once it connects, everything is normal.
I use a Netgear Power line Adapter and have been for years, and have never had a problem with it. I am running Windows 7 Enterprise 64 bit.

I'm running Win7 and have recently had problems at startup. Initially I thought this was a Skype issue as removing it seemed to work, but alas the problem remains with it uninstalled. The PC boots ok and I can open programs quickly enough, but if they need internet access they hang for 5mins or so before the block clears and all is well. I have recently changed ISP provider to BT Broadband (UK) and have a new router which sets itself up and had been working fine.

I bought a secondhand small business router (model 1941 Integrated Services Router) for personal use. It runs version IOS 15.0(1)M1 software, which seems to work well, but I'd like to download a firmware update that addresess some of the security flaws in this software. When I tried the download process it told me I need to buy a service contract first? Is this right, or am I doing something wrong?

I plan to buy WS-C3560CG-8PC-S (Catalyst 3560-C) for my home lab. I just created a new account on [URL] (I did not register any equipment or contract for that new account). I was able to download ios 12 and 15 for that switch.- Will I be able to flash one of these versions when I will have the new switch ?Cisco warranty for these Switchs (Enhanced Limited Lifetime Hardware Warranty,[URL] says NO OS Software Updates included. Does tha mean that I can download ios updates but won't be able to flash the device or use it ?- Do I really have to buy Smartnet support to be able to update ios for that switch ?

I have a 2 member 3750-x switch stack that was upgraded to 15.2 today via CNA. All the files were transfered and expanded correctly and it got to the step where the switches needed to be reloaded but on reload they froze.
I connected a console cable and power cycled the stack. I see the flash initialize and then the IOS image start to load. Lots of @ symbols and then nothing. It just sits there. The system light on the switches, while flashing green during the load, is now off. No light at all. But fans are running and the process will repeat itself if power cycled.

I've recently tried to update the modem firmware on an 887M that is actually using an Annex M service and after rebooting to kick in the new modem firmware, the router loses sync. I've tried this with various other 877, 877M, 887 and 887Ms on normal Annex A services with no problems, but this Annex M service doesn't like it at all.

you can update your ios for free within the 90 day warranty.e.g. a customer bought a asa 5510 and installed was a old version of the ios. now our customer complains that he wants to have the current version.but as far as i know he would need a smartnet in order to get the current ios.
but i think to remember that someone told me that you can update your ios device withthin the 90 day warranty. true?

This feature doesn't work as advertised on the Release Notes and other documentation. After 12 hrs of lab work and a tlwo day support call to TAC, they finally came back to me that:
IOS Upgrade works well if you use the command force-reload, without force-reload, it won't work. --"of course with this command the complete stack will go down and the purpose of RSU will not serve"
Then they pointed me to a bug that I could not find in the bug tracker unless I searched by the bug ID number ?? CSCua78897
Unfortunately this bug has a closed status and is not slated to be fixed ?
