Cisco Switches :: Configure SRW248G4 Switch Through Console Port?

Jun 2, 2013

I want to configure my SRW248G4 switch thru console port. Unfortunately in this switch there is no RJ45 console port input, I can only see cosole port that is look like RS232 input. I bought two standard cisco console cables that have one end with db9 and one with RJ45.

Now I have and idea to put one end of one cable (db9) to switch, and one end (db9) of second cable in my computer (COM input/output)
 
I need to connect two RJ45 together - this is not a problem, I know how to do this. Here is the question :I know how pinout in my computer look like but i can't find pinout of console port in my SRW248G4. There is many pictures in Internet, for many Cisco devices but this isn't working. Maybe in LINKSYS pinout look different ?

Cisco Switches :: Linksys SRW2016 Switch Serial Console Not Working

Jan 5, 2011

I have had the switch for about 2 years and recently moved.  The manual specifies:
 
38400 bps and 8-n-1 serial port settings using DB9F to DB9F cable.
 
I have done this and tried using multiple machines/ports/cables as well as several peices of software (minicom, PuTTy, hyperterminal) and none give me any output from the switch at all.
 
The trouble is that in its original config, it had 1 port locked into its own VLAN for management with port security and an obscure RFC1918 IP address which I cannot recall for the life of me.
 
At this point, I have no access to TCP/IP management so serial console is my last hope and is not working.

Cisco Switches :: 3750 / SMB Switch Integrations With Non-SMB Infrastructure?

Jul 27, 2011

A customer is expanding their network into another wing, and they have a good number of existing Small Business switches (specifically the SGE-2010P - [URL] that they're interested in possibly deploying.  They have a full-blown Cisco infrastructure and voice deployment (Cat 6500 core switches, 3750 switch stacks, Communications Manager w/ over 1,000 phones, etc.).
 
The general concern is whether there is ANY known issues or concerns with trying to mix/integrate the Small Business equipment with non-SMB infrastructure. Looking at the datasheet for this switch, it's clearly PoE, supports QoS, although it doesn't specifically indicate it can provide a voice/auxiliary VLAN for a phone detected by CDP - that would be a big deal.  So basically, "a switch is a switch", and I'm just posing this question to make sure there's no reason (technically or from a support standpoint) that we would not recommend integrating these.

Cisco Switching/Routing :: 3750 Turn Off 802.1x Console Messages

Dec 16, 2012

Is there a way to turn off 802.1x authentication messages to the console of a 3750 switch? The issue we have is that we like to monitor the terminal when remotely configuring our switches. However, every time a computer authenticates to the network we get messages and sometimes quite a few depending on the situation.

Uverse Lockups And Router Reboots?

Apr 6, 2011

We've had UVerse for about a year now - but lately we've had weird problems:

-about every 2-4 weeks, the router will spend a night constantly locking up and rebooting itself. ATT says they don't know why, and wanted me to check the power?? When it does this, it will do it for 30 minutes to TWO HOURS.

-every couple of days, the channels will freeze. If we change channels and then back, it returns to normal for a bit. Sometimes for a while, sometimes only for a minute. We have two boxes, each one does it. Even affects DVR playback. Internet doesn't seem to be affected, so I had originally though it was the boxes. ATT has remoted in, and can't find anything out of the ordinary.

Cisco Switches :: SF300-24P Console And Factory Reset

Jan 10, 2012

My company just bought a SF300-24P, got it configured without much issue.  Today I try to get into it and I can't.  Tried via HTTP and console and nothing happens.  Decided to try to reset it using the button on the front.  Using the documentation, I held down the button for over 10 seconds.  Didn't reset to factory defaults, tried again and rebooted it, still nothing.  What I am I doing wrong. Also nothing comes up on console window and I'm using the setting for Hyper Terminal that the documentation says I should use.

Cisco Switches :: SRW224G4P WebView And POE / Can't Login To Gui Or Console

Jun 8, 2011

The switch functions and operates fine but I can no longer login to the webview(GUI) and when I use a serial cable to console in to it, it shows nothing on the hyperterminal meaning no login. How can I get back into the switch to manage it or reset it back to factory settings? I kept the default IP address and I enabled HTTPS to login by gui, well I got in by HTTPS so I went in to turn that setting off and hit apply and now I can't log into it at all.

Cisco Switching/Routing :: Using Web Console To Manage 2960 Switch

Nov 13, 2011

I have a client whom has asked me to enable web management on some of his 2960 switches. I did not think this was going to be an issue, and so I told the customer I would set this up for him.
 
Much to my dismay, I have been able to get http and https enabled, and then authenticating locally for the HTTP access.  I then come to the screen once authenticated which is shown below:
 
The issue is that when I select "Web Console", it gives me a "Web Page Cannot be found".

Linksys Wireless Adapters :: WUSB600N And Random PC Lockups?

Oct 7, 2011

I have a problem with my WUSB600N in that it periodically stalls my PC for about twenty seconds.  It happens randomly, but particularly when I am using YouTube or playing online games. The symptoms are basically that the screen and process lock up.  Sometimes I can continue to move the mouse for a short period, but usually that stops moving too.  If I'm playing music in the background (iTunes usually or YouTube) then the music keeps going after the lockup, again only for a short period.  Usually about twenty seconds or so later, the whole things recovers.  I've tried Alt-Tab or Ctrl-Alt-Del while locked, but that does nothing until the system recovers, at which point i find myself with the Task Manager window or back in Windows, so clearly the keystroke has hit the system normally.
 
PC is running Windows 7 64, with Avast antivirus, Zonealarm firewall, Malwarebytes antimalware.Its an E6750 on a P5N32E Deluxe with 2G RAM.The wireless access point is about five metres away in a straight line through an open doorway.  Signal strength is generally excellent (4 of 5 bars is almost invariably showing whenever I look).I've tried one site which suggested using the RALink drivers instead, but I could not even get that to recognise and activate the WUSB600N, so I'm back with the current (as of today) Linksys drivers straight off their site (18-Jan-10 3.0.10.0).  Adhoc 11n disabled, 11h enable, Multimedia/Gaming disable, Radio on/off enable.  I've tried with all enabled, but still happens.  So I'm back with default configuration.

Cisco Switching/Routing :: 2924 Switch - No Response From Console Port?

Dec 11, 2011

I have 2 Catalyst 2924 switch in a home lab.  Both of them have developed the same problem at the same time (strange).  I have tried all that I can think of.  I can  telnet to them but cannot access via the console port.  On a telnet session I execueted a "write erase, reload" on one of them.  As I anticipated this threw me out of the telnet session and I presently have no access to that switch.
 
The console cable is fine, works for all other devices.

Cisco Switching/Routing :: Cannot Administer Catalyst 2960 Switch Via Console

Feb 20, 2013

I want to configure my switch via console cable, the switch boots up normally, and there are no configurations present on the switch.  However, anything I type does not appear on the terminal client.  I used several terminal clients (TeraTerm, PuTTY, HyperTerminal), all latest versions as well as different PCs.  I even forced the switch to rommon mode, still, anything I type does not appear on the terminal client.
 
Here's the output of TeraTerm:
 
Boot Sector Filesystem (bs) installed, fsid: 2
Base ethernet MAC Address: e8:40:40:06:f0:80
Xmodem file system is available.
The password-recovery mechanism is enabled.

After the last line, I can not type any command at all.  I encountered this on three 2960 switches that we have here in our laboratory.

Cisco Switching/Routing :: 877 - Getting Junk Language When Accessing Switch Via Console

May 12, 2012

I've been assinged a task to connect our branch office with the head office, so that the IP Phones in the branch office can be connected to Cisco Call Manager at head office. To accomplish this they have given a Cisco 877 Adsl router a 10 Port 3-COM POE Switch and 3 Cisco 7911 IP Phones. Currently the there are 7 PC's Connected to 3 COM Switch which indeed is connected to a Internet router(Speedtouch). First I thought of connectiong the IP Phones to the Ethernet Port on Cisco 877 router but had to change my mind as the ports are non POE ports and I do not have adapters for IP phones. So I've decided to connect the Phones to 3 COM Switch and create VLAN's (DATA & VOICE) and pass the DATA traffic through Speed Touch and Voice traffic through the Cisco 877 router, but when I tried accessing the 3-COM Switch via Console I am getting Junk language( See the attachment for reference).
 
how can I pass through this Junk messeges and access the switch

Cisco Switching/Routing :: Console Authorization On Nexus 7000 Switch Not Working?

Nov 29, 2011

i'm trying to enable command authorization for ssh as  well as console access to a Nexus 7010 box (version 5.0). Following is  the config:
 
aaa group server tacacs+ ACS5-1
    server 10.12.19.11
    server 10.12.19.12
    source-interface loopback0
snmp-server enable traps aaa server-state-change
aaa authentication login default group ACS5-1 local

[code]....
 
As  you can see, the default group configuration ACS5-1 for authenticatoin  has applied to both defaults and console. But the command authorization  does not appear to be applied to the console. As a result, when i login  from the console and get authenticated, the command authorization does  not trigger and i can run commands I'm not supposed to. In the  configuration, I do not see "aaa authorization console" option unlike we  have in IOS.

Cisco Switching/Routing :: 3750 Stackable Switches Etherchannel To Core Switches

If I have two stackable switches one switch uplinks to one 6509 core switch and the other connection uplinks to another 6509 core switch, and also the other stackable switch does not connect to the core switches. Because I am using hsrp and also we are not using vss then one uplink to the core is not in used only ones is so then how does creating an etherchannel between does two uplinks to both core switches benefit me in anyway such as more bandwith and using both uplinks at the same time or I'm I wrong?
