Cisco WAN :: 3945 Router CPU Temperature?
Nov 8, 2012
I am trying to find out what the 'normal' operating temperature of the CPU in a 3945 router is? We have just replaced some 2800 routers for 3945's and the NMS server initially complained about the new router CPU temperature being too high. Compared to the 2800 the CPU temperature is much hotter - 50 degrees celcius as opposed to 20-smothing degrees. I have searched but can't find what are considered 'normal'?
This is the output:
router#sho environment allSYSTEM POWER SUPPLY STATUS==========================Internal Power Supply 1 Type: DCInternal Power Supply 1 12V Output Status: Normal

We have a Cisco 2801 router running IOS "c2801-spservicesk9-mz.151-4.M4.bin" which we upgraded from previous “c2801-spservicesk9-mz.124-3d.bin”.
Requirement.
We want to monitor the device temperature via snmp but unable to do because temperature ratings are not available on "show environment all" output like below.
Routeri# sh environment all Fan 1 OK Fan 2 OK ILP Power Supply - Absent Fan Speed Setting: Normal
Where as on Cisco 2811/51 & Cisco 3825/45 we can get temperature ratings on "show env all" output.
As per link [URL] below commands are supported on Cisco 2800 series router.
Command options
• show environment all
• show environment fans
• show environment leds
• show environment power-supply
• show environment table
• show environment temperatures
• show environment voltages
I want to know whether this is Cisco 2801 platform limitations or something else. tried to find Cisco doc on this but no luck.

I cant remember where I read it but when I noticed that my HDD was running hot even when it was meant to be idle, I read that the router causes the storage device to run at full spin regardless.
I was wondering, do we know if that issue is fixed with this latest firmware update (June 14th)? I've had it on for about 10minutes but I'm not sure how long it takes to get to the temp that it was running at before.

I reported a really strange issue on a Cisco Router 3945. Here below info about release software used: [code] Please look at a brief extract of router running configuration file: [code] It’s an easy configuration of Extended ACL and the application on an Ethernet interface. The expected result is:
- The interface works properly (because access list is permitting every kind of data traffic in input)
- Checking “show access-list 180”, the counter of matched packets increments for all the packets that are forwarded inside the fa0/0/1.
But actually the Fastethernet 0/0/1 drops all the packets as if all the packets don’t match with access list (And this behavior is really incredible). The interface couldn't be used anymore because any kind of data traffic is denied.

I am getting the following message from a 3945 router: %CERM-4-TX_BW_LIMIT: Maximum Tx Bandwidth limit of 85000 Kbps reached for Crypto functionality with securityk9 technology package license.
That router has 8 Gre/IPsec tunnels and one of those tunnels is 100Mbps.The question is, could I get 100Mbps as the sum of all tunnels, or is there a restriction to 85Mbps ??

We just recently purchased a 3945 ISR G2 router and have a SRE-910 module (with two hard drives) configured in a Raid 1. We are running a stand-alone version of ESXi on the service module and I'm trying to figure out how to monitor the status of the Raid on the drives (along with other health issues). SNMP has revealed nothing so far and even opening a support case for which MIB's to use has proved fruitless. All the documents I find on monitoring the modules say to use LMS which is now Cisco Prime. I've downloaded the trial copy, put in the SNMP settings and scanned the router. I get device results and it shows that I have the SRE-910 module installed, but I get no other configuration / device informaiton from the module itself.
I tried to create a new Monitoring template using the NAM health as the base template (which I'm assuming this is the correct template). Unfortunately, when I actually try to deploy the template against the discovered router, I get an 'Unexpected end of list' error which makes me assume I'm still doing something wrong.

CISCO 3945 Routers - Are the 3945 Router power supplies load balanced by default? We are trying to determine if our switch/server rack at our remote location has maxed out it's power load requirements. I just need to know if the 3945 power supplies load balance by default or if the redundant power supply is ON but not really providing the router with power and is just there incase the other power supply fails .

We are having problems with a two router 3945 in HSRP and a switch 2960.The two routers are connected to the switch 2960 through differentes ports. The problem is that we loose connection between the router and the switch.When we excute the command: show cdp neighbor at router, it shows nothing.If we try to make ping to the 2960 switch it is no reachable.If we make ping to the other router 3945 it is not reachable.All other function of the router are o.k.We are attaching the IOS of the routers and switch 2960 and a document in which make reference to a BUG in which mention about arp overwrite due arp attack which produce DoS.

I am using DHCP/TFTP to autoconfigure a 3945 router. The router properly obtains an IP address and finds the correct TFTP server. The issue lies in the download of the configuration file from the TFTP server. The router downloads the file, gives the "Ok" message, and prompts you to press Return to get started. When I view the running-config, several commands are missing from the Serial 0/0/0 section (HWIC-2T). If I modify the config file on the TFTP server to use Serial 0/0/1 instead and repeat the process, the configuration file loads without any issues and Serial 0/0/1 has all of the commands.
I also tried moving syntax around in my config file, but the end result is still the same. If I use Serial0/0/0 - I don't get all of the commands. If I use Serial 0/0/1, I do.

We bought two packs of IPCAM online from a vendor named HooToo, who seems have different online sites for selling various surveillance cameras. What we purchased is a unit with model no. of HT-IP206, according to its advertisement it has a storage temperature as low as minus 10 degree, and adversely high up to 60degree. While on the other hand, it states that the operating temperature shall be strictly between zero and 55degree. What Im concerned is that what if temperature drops down to minus when a camera is fully operating? Shall extra heating system be needed while the real temperature fails to meet the above-said requirement?
