Cisco Switching/Routing :: 871 - Quiet Mode / Pull An Ip Address?

Apr 23, 2012

I have a user who is a work at home.  She has an 871 Cisco Router with is connected to an ISP modem.  Lately she has been getting connectivity issues.  And a tech from the ISP troubleshooted it and said that the Cisco Router was not pulling an IP address.  He said he queried the modem and got a null response on the IP address of the router.  He cleared the ARP cace and rebooted the ISP modem; still the Cisco Router would not get an IP address.  However when I went into the router, I noticed that there were many log alerts.  It seems that the router is in quiet mode.
 
Code...

Would quiet mode cause the router to lose connectivity or cause to not pull an ip address?

Cisco Switching/Routing :: Quiet Fanless 24 Or 48 Port Switch With POE 3560C-12PC-S

Jun 10, 2012

I have an office that I need switchports for 24 cubicals that need 2 network ports each with POE.  The problem is due to my cable path the switches need to be right at the cubicles themselves and they need to have no noise. 
 
The compact switches are quiet enough but in order to get the density I need I will have to use 4 3560C-12PC-S and they don't have stacking cables. 
 
My question is, is there a POE enabled switch that is larger than 12 ports or has stacking capabilities or is the 3560C-12PC-S or 2960C-12PC my only options?

Cisco :: LMS 4.1 User Tracking Does Not Pull IP Address From Hosts?

Oct 25, 2011

New install discovered router and switches at same location with no issues. However when running an acquisition on those switches most fields are populated except the ip address of end host associated with port. Mac address, port speed, etc. but no ip address info on per port basis. Using snmp v3 if that makes a difference.

Routers / Switches :: Linksys Wrt54g - IP Address Won't Pull Up?

Jun 16, 2011

I have a linksys router model#wrt54gt v1 and I can not pull up the router's ip address to change the security settings. I have checked and I have the correct IP address of 192.168.1.1. I can ping the router and everything hooked up to the router is now working correctly. I was having problem with the router losing the internet ip address and having to turn everything off and then back on to connect to the internet. I reset the router and it seems to have corrected that problem but I now can not pull up the router's ip address. I have tried in Internet Explorer and Firefox. I have tried typing thebefore the ip address but it will not pull up. I have read countless posts trying to trouble shoot and figure out what's wrong with it and nothing will work.

Cisco Switching/Routing :: Changing 4510-SUP-6E Redundant Mode To Share-Backplane Mode

Mar 12, 2013

I received the following info from Cisco's TAC and wanted to inquire further before I start reconfiguring the switch:
 
In a redundant Sup-6E setup, the following configuration is supported :
 
- 1 TenGig uplink on Active Sup and 1 TenGig uplink on Standby Sup
- 1 TenGig uplink on Active Sup and 2 Gig uplinks on Standby Sup
- 2 Gig uplinks on Active Sup and 1 TenGig uplink on Standby Sup
- 2 Gig uplink on Active Sup and 2 Gig uplinks on Standby Sup
 
If you invoke shared backplane mode, the following configuration can also be supported:
 
- 2 TenGig uplinks(blocking) on Active Sup and 2 TenGig uplinks on Standby Sup
- 2 TenGig uplink(blocking) on Active Sup and 4 Gig uplinks on Standby Sup
- 4 Gig uplinks on Active Sup and 2 TenGig uplinks(blocking) on Standby Sup
- 4 Gig uplink on Active Sup and 4 Gig uplinks on Standby Sup
 
Here's the command and information about the "shared-backplane" mode :- [URL]
 
Currently, we have 2  SUP 6-Es(Module 5 - Active and Module 6 - Stand-by) setup in a redundent mode. I am planning on changing the redundent mode to the shared backplane mode so I can use 2 TenGig converters to uplink 2 access-switches. We purchased 2 TenGig converters and here is how I am planning on using them:

1- One will be used  to uplink to two 3750 switches(stacked)
2- One will be used to uplink to a 2960 using a Gig SFP
 
My questions are:

1- Do I have to install the 2 TenGig converters(4-Gig Uplinks) in the same Module? Or can I use one one in module 5 and the second one in module 6?
2- Will changing the redundant mode to the shared backplane mode require rebooting the switch or disrupt the funtionality of the other linecards?

Cisco WAN :: WS-C3750G-48TS-S Quiet Replacement Fan?

May 3, 2013

Any replacement fan for the WS-C3750G-48TS-S switch that runs quieter than the one originally built into this router?  I've searched a number of web sites and found plenty of replacement fans available but none of them show noise level specifications.
 
particular manufacturer/model combination that works in this router that will drop the noise level down while maintaining air flow.  This switch is in a short network rack in an small office that also includes people.  The current noise level isn't defining like some servers, but is loud enough to be distracting.

Cisco Switching/Routing :: Cannot Get Out Of Rommon Mode 1760

Dec 10, 2011

I'm currently pursuing to take my CCNA and am currently studying for it, but have recently encountered a problem with one of my 1760 routers that I can not solve.Yesterday I went to boot up my router like normal, however when I went into hyperterminal I noticed the router was in Rommon mode. Thinking I could change the configuration registry, I tried to bypass the NVRAM by using confreg 0x2142. However this still causes the router to go into Rommon mode. I am getting an error that states that there is insufficient memory to load the IOS image. [code]
 
I have used the dir flash: command and can see the IOS image, and try to boot from it (boot flash:iosimagename) but it will still go back into rommon mode. I also just swapped the RAM from my other 1760 into this 1760 and it booted up and went into normal configuraiton mode without any issues. However, the other router now will not load it's IOS image and I get the exact same error.I'm at a loss here, and have searched to figure out where or how I can just wipe the router clean to try and start fresh, but cannot get out or Rommon mode. The only thing I can think of is that the RAM went bad since it wont boot up either machine.

Cisco Switching/Routing :: Cannot Change SG300-28 To Layer 3 Mode

Jan 31, 2012

it says that the cisco sg300-28 managed switch default system mode is Layer 2. but i want to change it to layer 3.
 
i can't get inside the "Console Interface Main Menu" where the switching from L2 to L3 will be done.
 
I have done the ff:

1. Upgraded firmware to 1.1.2.0 (latest)

2. Reset the switch to factory defaults.

3. The guide stated that in order to perform telnet to the switch, you need to enable it. So I logged in first in to the web GUI and enable telnet service.

4. I can now start telnet on the switch but I can't see the "Switch main menu".
 
All I can see are these lines from telnet:
 
User Name:cisco
Password:******
  
switchd5928c#
 
I just want to know how to get into the console interface main menu where these lines should appear so that i can change the system mode:
 
• System Configuration Menu
• Port Status
• Port Configuration
• System Mode
• Help
• Logout

Cisco Switching/Routing :: Changing Power Mode On 6500

Oct 2, 2012

We have two 6500s. One is running in power redundant mode and the other is running in combined mode.We need to change the one running in combined mode to redundant mode to ensure it can run ok on one supply if needed but I have a couple of questions.

1. Assuming that we are not oversubscribed on the power allocated, does changing the mode cause any disruption?

2. The switch running in combined mode seems to have allocated some power for an "Inline Local-Pwr-Pool" which is not allocated on the switch running in redundant mode (see attached). Does this allocation will be needed if we change the power mode?

Cisco Switching/Routing :: 3750 - ASA Multiple Context Mode

Nov 16, 2011

Im looking for some clarification regarding running a Cisco ASA in transparent mode with multiple contexts.  To give you an insight into the network design we have the following -
 
Collapsed Core/Aggregation Layer running Cisco 3750s.  The 2 Cisco 3750s are using SVIs with HSRP for default gateways per customer with a total of 8 customers.  Each customer is segregated into seperate VLANs with Cisco 2960 switches used in the Access layer.  Each customer has 2 Cisco 2960 switches with redundant uplinks to the Core/Aggregation layer.  Customers are spanning tree loadbalanced between core/aggregation switches.
 
What i need to now do is add two transparent firewalls into the mix in either an active/active or active/standby setup.  I need the firewalls to support all 8 customers,  therefore I am guessing they need to run in multiple context mode.  Having read into this it has left me somewhat confused as to how to integrate them into the above setup as a bump in the wire so to speak.
