I want to upgrade LMS 3.2 to 4.1. But when I look to "Special Notes and Exceptions for Devices Supported" document ,It seems that 2811 have 2 SysID.

Why there are two IDs for the same hardware and under which ID will my 2811 routers be classified into inventory database. This information is important since customer want to have support of 2811 in CiscoView of LMS 4.1 (around 200 devices).

Cisco WAN :: 2811- ILPM 4 Motherboard Out Of Order After Upgrade

Apr 2, 2012

I recently upgraded my 2811 router with an AC- IP power supply, and installed a HWIC-4ESW-POE, with an Inline Power Daughter Card (ILPM-4) installed on the HWIC.
The second I turned the router's power on, there was a spark and a burning smell. Everything still works, except POE. Examining the card, I see it caused a circuit on the ILPM-4 motherboard to blow, and there is black residue everywhere. This is a Genuine Cisco power supply, but why it's done this.
Furthermore, when the power supply was first installed, it had so much electricity (and I know this is why the card got toasted) that touching the end of the console cable or an Ethernet cable connected to the router, or even the router chassis, would cause you to get a small electric shock, like touching a mild electric fence. Clearly, the power supply I installed is "too-powerful", but it is a 2811-AC-IP and nothing should have caused this.

AAA/Identity/Nac :: CSACS-1121-UP-K9 - Possible To Upgrade It Being Non Upgrade Part

Sep 10, 2012

Is it possible to upgrade the CSACS-1121-UP-K9 to be a non upgrade part? We were going to upgrade from a Windows 4.x to the above Appliance (version 5.x) but there is now a reason to keep the old Windows version running therefore we cannot give the new Appliance the old ACS's licenses?!So we should have (with hindsight) bought a fresh version of the ACS 5.x rather than an upgrade.

I have a particular site that is causing me trouble, this site is connected in a back to back configuration using 2811 at CO and 2621XM at CPE.  The CO end is also the CO for 3 other sites so has a total of 4 wics installed (WIC-1SHDSL-v2), these other sites also have 2621XMs for the CPE.

Cisco WAN :: Configuring ASA5510 With 2811 ISR

While i know I can move most of the config unto the ASA, i know that the CME cannot be moved, hence I would like to do the setup such that users on the network still have access to CME.

Cisco :: Setup NTP Server Using 2811?

Sep 30, 2012

I've setup a NTP service by using Cisco 2811 routers. This works fine at the moment, but in the end there are some questions left.
1. I'm using two 2811 Routers, one for primary, which is resceiving the time from PUBLIC NTP 1, and one for backup, which is resceiving the time from PUBLIC NTP 2. Is it possible to compare these to times an check if the match? And if not, generate an alarm via e.g. SNMP
2. Is it possible to check via SNMP, if the routers are reaching PUBLIC NTP 1 and PUBLIC NTP 2 for sync?

Cisco WAN :: 2811 DSL Load Balancing

Dec 9, 2010

I have a Cisco 2811 router with two HWIC-ADSL cards configured for dsl connection. I have two lines from the same ISP and i am load balancing between them. I have created a couple of SLA's to check the state of the connections and add to the routing table the two default routes if both are up or any one of them is up.My problem is that when i  try to download big files (especially antivirus updates) the download at some point stops (especially the antivirus exits with an error of unreachability). If i shut down one line everything works fine.Could i use something (configuration-wise) to prevent this problem from happening?????Is there any way i can combine the two lines? They are simple ADSL connctions with static ip's.

Cisco WAN :: 2811 High Cpu Utilization

Apr 29, 2013

I have a 2811 that is really hitting the CPU hard.  Nothing shows on CPU processes.  It has an IPsec VPN tunnel back to HQ which also has a 2811 that terminates the VPN.  The HQ has 2-3 IPsec tunnels to other remote sites.  The CPU at the HQ avg 50% utilization during business hrs, peaks at about 80%.  The remote one is very high 95% peaks, avg 80%-95% during business hours with bandwidth utilization of only 10-20Mbps.  I read somewhere that its possible that fragmentation could be causing this.  My question is, if I set the MTU to 1450 on the remote, I am guessing I will need to do all the other routers as well, the HQ and other remote sites?  Siince they use the same outside interface to my HQ, is that correct?
