Cisco Switching/Routing :: 3560-X / USB Console Doesn't Work / RJ45 Works Just Fine
Nov 5, 2012
I've got a 3560-X that passes POST according to console, but there are issues nonetheless...USB console doesn't work. RJ45 works just fine. No status lights turn on at any point (e.g. syst, xps...). 10g network module is installed with a 10g LRM SFP. All lights on the module are amber. However, it passes according to POST. Switch passes traffic, obeys config, etc. Link lights on RJ45 ports work fine. This was brand new out of the box. Thinking about trying IOS reload..
I have a pair of OLD Cat6500's running CatOS: WS-C6509 Software, Version NmpSW: 7.6(16) Copyright (c) 1995-2005 by Cisco Systems NMP S/W compiled on Dec 22 2005, 16:37:19 System Bootstrap Version: 7.1(1) System Boot Image File is 'bootflash:cat6000-sup2k8.7-6-16.bin' System Configuration register is 0x2
I know these are no longer supported, but I have to ready them for migration. Recently a problem began with these switches. What happens is that when I telnet to them, I cannot authenitcate via TACACS. This works fine for all our other IOS equipment, just not for these 2 switches. The error is:" % Error in authentication" and then I get kicked back to the login prompt.
The odd thing is that when I connect to the switch via the console port, I can authenticate fine with TACACS. CMS> /c 14
I'm trying to connect a Cisco 2811 using an octal cable to a Juniper MX480 console port.Since the distance between Cisco 2811 and router is 20ft, im using couplers and a straight-through cable for the lack of slack. This wiring doesnt work, however in another city it works going straight from the Cisco 2811 octal cable to the router since they are in the same rack.
My parents have a windows 7 desktop with ethernet plugged in for internet. I use a Asus EEE 1005HA with jolicloud. They do not have wireless, only wired internet. When I plug in the ethernet cable, the netbook doesn't recognize the internet access. Nothing wrong with the ethernet port on the netbook, as i've used wired network at my dorm and the port does recognize the ethernet cable at my parents' house.
Also, is it possible to use the desktop as a sort of wireless router? Would connecting a usb wireless dongle to the desktop allow me to connect my netbook to the internet via the desktop?
I have a 3560-24ps, and I'm having issues with it booting. When I power the device up all the front panel lights come on like normail, and then the system light starts flashing like normal, but after 5 - 6 seconds the system light goes off. I don't get any output from the console, and the fans still run.
I have two 3560s that i would like to upgrade. But first i would like to make -absolutely- sure i dont wind up in a situation where i have to roll back over a console connection.to the day i still cant understand why oh why someone removed (or chose not to implement it everywhere) tftpdnld from rommon ;)
don't know what to do. For a good while now, at my home, the internet has been awful.Web pages barely load if at all, I can't play any online games, but when I start a download, either by torrent or regular, the download speed is perfectly fine, reaching the normal 500 kb/s. My router is TP-Link W9801G. We get TV through the router as well, and there never was any problem with it. It works fine, just like the download speed. The DNS and IP settings are all set to automatic like they should, and of course I've tried unplugging and resetting everything.I know it's not the computer's network adapter, because it's the same thing at my laptop when I connect to it wirelessly. The signal strength is at all 5 bars too
I have been using my laptop since a year now and yesterday suddenly my internet stopped working. On top of the connectivity bar a yellow sign appeared. Now my internet status is "No internet access" but when i connect my ethernet cable the internet starts working and i can see the "Internet access" status. I have re-installed my wi-fi driver too from the orignal CD that i got with my laptop, but still no luck also i did not install anything in past 1 week and the only anti-virus i have is Avast (tried disabling it too). I plugged out the cables from my router and plugged them again but that dint work too. There are 2 other laptops (running on windows 7 just like mine) on which the wifi connection is working but on mine it is not working.
I try connecting via ethernet cable and it doesn't seem to work until the administrator of the network (my brother) comes home and then turns his computer on and starts using it. However, if i switch to a wireless adapter it sometimes works (like right now) even when my brother is not using the internet. Also, i tried to connect via wifi on my macbook pro to the same server and it used to work flawlessly 100% of the time, now i can only connect once in a while for short periods of times.
Region : India Model : TL-MR3420 Hardware Version : V1 Firmware Version : 3.12.21 Build 120523 Rel.37880n ISP : Reliance
I've just set up a MR3420. It works fine in "WAN only" mode and provides access via our ADSL modem. It also works fine in "3G only" mode and provides access via a Reliance Netconnect+ USB modem (a Huawei E150 I think). I updated the firmware to the latest version in order to get it to work with the USB modem.
The problem I have is that when I set it to "3G preferred" it doesn't seem to connect over 3G. I can see it tries to connect but then fails and then WAN takes over. The connect and disconnect options are greyed out on the 3G page so I am unable to manually get it to retry. I've tried leaving it for a long time but it doesn't seem to connect over 3G ever. I've tried setting 3G to connect on demand and connect automatically but both behave the same.
I've been working on a 3560 that doesn't seem to map dscp values to a new value: mls qos map dscp-mutation ToR1 22 24 to 46
[Code]....
On the router on the other side, I created an acl that matched on dscp 46, but it doesn't match on it. I've tried moving the mutation map to the ingress interface and I've tried setting dscp with a service policy instead of marking COS and using internal dscp. Where is the mutation map supposed to be placed: ingress or egress? Also, I added an entry in the acl on the router to see if I was mapping to dscp 24, and I am:
[Code]....
So it seems like the mutation map is being ignored completely. Any reason why?
I have upgraded my C3560-PS-S switch to the latest IOS version 12(2)55-SE4 and it is not providing PoE anymore? It used to work before this upgrade? I searched Cisco bugtrack and there is bug defined for this IOS/Switch.

I have a E4200 v1, connected with a few PCs by ethernet ports and various devices by wifi. Now the wireless devices work perfectly but sometimes the PC via ethernet ports cannot connect to LAN and internet.
I have switch Cisco 3560 and I would like to filter multicast traffic. Short explanation. This are multicast addresses from provider on VLAN 888 :
I expect that streams from acl Streamfrom888 will be dropped and the rest of streams will be forwarded. Unfortunately traffic from all streams passs through.how to configure VACL or where in my configuration is mistake?
We have over 30 Cisco 3560 switches and over 10 VLANs on our network. In our example, VLAN 10 on switch IP 10.0.20.150 works fine and VLAN 10 on switch IP 10.0.20.24 doesn’t work. The below are both switches show vlan. url....I can’t tell what causes the problem and how to fix it. VLAN 10 on Switch 10.0.20 24 doesn’t work. [code]
I have a problem with my vpn concentrator. I cannot access it through console, I have tried every baud rate that is available on my SecureCrt but it won't display anything. At first, I thought that my console cable is defective but I was able to access a WLC via console cable together with the rj45 to db9 converter. I also tried connecting the vpn concentrator to a switch and enable the cdp in the switch but the "show cdp neighbor" can't detect or display the vpn concentrator even if the interface status is "up up". Is it safe to say that the VPN concentrator is already broken?
I have PC_A and PC_B connected to the same switch, and are put in the same vlan. PC_A is the master (source) and PC_B is the destination (client). IGMP Snooping is enabled by default.
Is there any reason why this should fail? There is no RP or any interface with PIM enabled. Its a flat network with a source and client in the same vlan...

We have a Cisco Catalyst 4506 running: "Cisco IOS Software, Catalyst 4000 L3 Switch Software (cat4000-I9K91S-M), Version 12.2(25)EWA14, RELEASE SOFTWARE (fc1)" I have configured the default gateway as: ip default-gateway X.Y.116.65, However, when I do, "show ip route", it only shows the 3 connected networks and states "Gateway of last resort is not set". The Command "ip classless" is not set. I read on some blogs that this might explain the issue. However, when I go into config mode (config t), I get the following output.
we've been using IOS for a long time, but are relatively new to NX-OS. We've got a central syslog server that all our devices log to. No matter what we do, we can't get our Nexus switches to log there. Here's my current attempt:
Nexus 7009, NX-OS 6.0(1)
# sh logging server Logging server: enabled {redacted} server severity: debugging server facility: local7 server VRF: default
[code].....
The default VRF is working. I see log entries in the logfile, but nothing arrives at the syslog server. It's not a config issue on the server, because tcpdump shows that no packets arrive from the IP for loopback 0.
I am trying to configerate static switchports on our nexus 5548 (nx-os 5.1(3)N1(1)) over snmp.The support-list url... states that the CISCO- VLAN- MEMBERSHIP- MIB is supported.I can read the information, but if i try to set vmVlan or vmVlanType i get the message: "SET failed. ("ip-address"). Information: Not Writable."I can use set_request in general (e.g. CISCO-CONFIG-COPY-MIB). how to set the vlan and vlan-type over snmp?
A few days ago i tried logging onto to League of Legends, and my net disconnected. Thinking nothing of it, i reset the router and tried again, to no avail. Then for the last few days i can't get on skype, LoL, or any other program that uses the internet. I can get onto websites and such( using firefox) except i can not load youtube videos, otherwise my internet disconnects for a minute or so.
While im playing games like battefield 3 left 4 dead 2 or minecraft i get rubberbanding lag which is basically my game character running foward then being shot back to his original postion. I originally was using a wireless usb adapter so i blamed it for the cause of the lag. (My pings were fine btw) I went to ethernet for a week and the lag went away so everything is fine via ethernet. I just bought a new wireless card but there is still this terrible lag!
I am having trouble connecting to the internet, but not my network, when I assign a static IP to my machine. However, when it's set to DHCP, it works just fine.
Pertinent info:
-I'm connecting to a Linksys WRT610N router via a wireless USB adaptor, Netgear WNDA3100v2;
-Service is Time Warner Roadrunner cable;
-There is no IP conflict as I've got DHCP range set from .200-.249 and this machine's static is .100;
-All the other devices in the house are on static starting with .101 up and they all work fine, both wired and wirelessly;
-Can see and connect to all devices in the LAN, including the router, but nothing outside
Earlier my desktop was to b in d same place where the router was der. Everything worked fine. Now I decided to shift my desktop to another room. I have kept the router at the earlier place only. I have brought a 25m long new cat 5 cable. When I connected it to my desktop, the orange led on ethernet port do not light up and the desktop is unable to detect the ethernet cable and hence the internet connection. On the router, a light of ethernet keeps on blinking every 1 second. I was worried whether my ethernet port got fried. So i inserted another ethernet cable, but then the ethernet orange light came and the pc detedted the connection. Therefore I thought the cable might be faulty. Therefore I connected my laptop with that 25m cable. But my laptop detected it and showed the internet connection. But now when i again connect the cable to my desktop, there's no light and the pc does not detect it. However, if i connect the 25m cable to my desktop then during boot the ethernet light on router is stable just as when it is normally connected to the internet. But when i go into windows it starts blinking every 1 second.
My router is MTNL Model No. UT-304R2 Desktop - Asus P7H55, core i5 Laptop- HP 2000 Windows 7 Ultimate on both desktop and laptop.
Internet works fine for a few minutes(around 2-5 usually), then it completely stops. It doesn't say it was disconnected, it just stops.Wireless has been working just fine the past few days.) We have used a desktop computer with this type of setup before and it worked just fine, that desktop was like a 2001 Dell that could barely stay on.
