How to enable IPS IPS/IDS in cisco 2811

Hi all,
I have a Cisco 2811 with IOS Version 12.4(20)T and I need to enable IPS or IDS in this. What is the config for this?
First of all, I need to know whether I can do IPS/IDS in my router as well..
- Ribin

Hi,
I did enabled IPS in the router and configured to notify to our log server. Below is the log I received in my log server.
What does IPS does now and what kind of logs I can expect?
Thanks,
Ribin

How to recover mbrd_e1t1_vic_connect: setup failed on cisco 2811 routers

Dear All Experts
I have three cisco 2811 routers, Router A has both 4 FXS & 4FXO port , Router B & Router C have 4 FXS port. connect with Alcatel PABX.
Now, the problem is ph lines are down after 3 days or more. Whenever down, i try to refresh voice port , with " shut & no shut " on each routers.Now i face the problem that is whenever i make shut & no shut on Router B site, ph line is ok there. But in Router C site , ph line is down. So i refresh @ Router C site,ph line is ok but in the router B site , ph line is down again.
I try several ways for shut & no shut. i have no idea. i checked log file on Router A , here is

How to enable IP SLA on cisco switch

Hi guys,
I am trying to enable IP SLA on a Cisco 4948 switch (running 'cat4500-ipbasek9-mz.122-46.SG.bin') to test CiscoWorks IPM using this swtich as a source device. But I can't run the command "ip sla monitor" on this switch. It just has "ip sla responder". Does anyone can help me, please? Is it possible to configura IP SLA on this source switch? Or can I do it only on routers?
Thanks,
Regards.
Flaviano.

IPSLA is supported in Cisco 800, 1700,1800, 2600,2800, 3500, 3750, 3600,3700, 3800, 4500, 6500, 7200, 7500, 7600, 10000, and 12000, ASR-1K Series Routers. Future support includes CRS-1, ONS ML Card, and Cisco 7970 IP phones in 2005.
IPSLA-VO (Video Operation) is supported on Cisco Catalyst 3560-X, 3750, 3750-E, 3750-X, 3650, and 3650-E Series switches & EtherSwitch Service Modules (SM-ES3G-16-P) which emulates a 3560 switch within the ISR's. You can use the EtherSwitch Serv Mod in the ISR's as well and use IPSLA-VO.
The 2900/3900 ISR's will support IPSLA-VO natively late this year.

How to enable IDSM-2 Signature through GUI

Hi Guys,
We are using IDSM-2 module in cisco 6509 chassis.I believe that only the default signatures were enabled on it at the time of implmentation.Now when I monitor
it (I use cisco IDM as the GUI to access IDSM-2) like after 6 months I could find that it has a bulk of sigantures on it which are not enabled.Could you
please guide me how to enable these sigantures on IDSM with out increasing the load on it.

Welcome to the world of tuning your sensor.
First thing you should know is that all signautres were not ment to be enabled simultainously. Some signatures are appropriate for your envioment and some are not (say you run a Lunix only shop). Some signatures have such a high false positive rate that they are essentially useless. Some signatures are actionable (meaning you can do somthing about it) others are not (like scans and recon sigs). You need to define what your goals of having a IPS are:
To generate pretty reports for management?
To investigate all your high severity events to clean up your infected hosts?
To "set it and forget it"?
Your goals will drive you toward an appropriate set of signatures and actions you wish enabled. As always, whatch your sensor load when you make changes, you don't want to overload that thing and start missing packets.

How to enable SSID broadcast? (E4200 Cloud f/w)

I got E4200 v.2 with the latest cloud firmware. On the previous (non-cloud) firmware there was an option to enable or disable SSID broadcast, and I disable it. Now I want to enable it back, but can not find this option in Cisco Connect Cloud.
So there is a question: how to enable SSID broadcast on the E4200 v.2 with Cisco Connect Cloud firmware?
wbr, bg

In your case, you need to reset the router to factory defaults, at which point the SSID will be set to broadcast and it cannot be disabled. To know more about why there is no option to disable the SSID broadcast anymore on the Cloud firmware, click here.

How to enable Channel 13 on WET54g

I am using it in Europe and need to enable channel 13 so I can connect to a network on this channel. I vaguely remember being told this was done by accessing a hidden setup page. Can anyone tell me how to enable channel 13 on a WET54g V3.1?

This seems to me like poor and outdated policy. It reminds of times when you could not take a laptop to Europe because the power supply was only for 110 V. Most manufacturers have moved to simplifying things for the customer and for themselves by making models more universal.
>> Flashing other firmware may brick the device. You can never rule that out.

>> Possibly it won't accept it but usually hardware versions between countries are identical.
You say it should "not cause problems" but "may brick the device". I would consider a bricking the device to be a "problem". I guess I can interpret it to mean that damage is unlikely but possible. It gives me pause as I do not want to risk bricking it.
The device label says it is WET54g V 3.1 At the US site http://homesupport.cisco.com/en-us/support/bridges/WET54G the choice for hardware version only goes up to V 3.0. Puzzling.
At the European site http://homesupport.cisco.com/en-eu/support/bridges/WET54G/download I found support for version 3.1. Interesting and puzzling since my 3.1 is American.
There, in the EU site, I found a file named WET54Gv3_1_v2d16.zip which contains two files:
- wet54gv3_v2d16_us_20091027.img
- wet54gv3_v2d16_ce_20091027.img
There is no explanation in the release notes of which one to use. The names differ only in two characters: us/ce. I would assume "us" is for USA but what would "ce" be? I was expecting something like "uk" or "eu". I am guessing the ce version is for Europe but I want to be sure before I start messing. I have never flashed anything and I have no idea of the degree of risk involved.
You can reload it with this firmware wet54gv3_v2d16_ce_20091027.img.

How to enable callback

Hi Netpros,
I have 3660 router with NM-16AM, Modem type is microcom_mimic. I was interested in configuring callback facility on this so that I could connect to this Router from my home. How can I achive this. I am able to dial into the router succesfully. How to move forward, any help??
TIA

You can call back PPP clients that dial in to asynchronous interfaces. You can enable callback to the following two types of PPP clients:
Clients that implement PPP callback per RFC 1570 (as an LCP negotiated extension).
Clients that do not negotiate callback but can put themselves in answer-mode, whereby a callback from the router is accepted.
The below link describes how to enable callback

How to setup Guest Network Name in Cisco Router

Hello everyone!
The first. Sorry my english =)
I want tald you how to change guest network name in cisco (what have different name)
What we need.
1. Cisco Connect for Mac OSX (i use snow leopard and Cisco Connect for E3000)
2. Terminal
Okay. Let's go.
1. Install Cisco Connect for OSX
2. After setup - slighty setup your cisco router (give something name and password), then, when cisco connect say you "You now connected the internet" and going to main screen - exit from cisco connect
3. Open Terminal (Or you can use Finder (go to Application, show package content Cisco Connect))
4. Go to /Application/Cisco Connect.app/Contents/Resources/lcid/<your setup language, for english - go 1033>/
5. Edit resource_strings.pus (vi resource_strings.pus)
6. Change "-guest" in string <LocalizableString RcFileId='10019' BaseTextHash='0xA65E286D' BaseText='-guest'/> for something what you want. For example, i changed for ' Guest Network'
7. Save
8. Open Cisco Setup
9. Go to router configuration and change desired name. I changed to 'Grizlly Bear'
10. After setup name - go to Guest Setting and Enable. As you can si, your guest network name set as 'Grizlly Bear Guest Network'
11.Exit Cisco Setup
12. Go to web interface setup
13. Setup Wifi manual and change SSID for diferent names. I change 5Gh to 'Grizlly Bear Hi-Speed Network' and 2.4GHz to 'Grizlly Bear Main Network'
14. Setup your hostname for all services (fileserver, media server, etc)
Woala!
We have three diferent names network!
Questions?

In order to enable Guest networking, the AirPort Extreme must be configured as your "main" Internet router. In this configuration, Connection Sharing = Share a Public IP address. The Extreme would be connected directly to the Internet modem and NOT downstream of another router with NAT enabled.
In this configuration, the Guest network would provide access ONLY to the Internet and NOT to your LAN.

IPS Signature DataBase - ASA IPS/IOS IPS/IPS 42xx/AIP-SSM

Hi,
Can anyone briefly tell me the signature database details (No of Signature) among the following devices,
-->ASA IPS/IOS IPS/IPS 42xx/AIP-SSM.
Thanks,

IPS on ASA/PIX = just 50 or so common signatures
AIP-SSM module = same signatures as Cisco 4200 series sensors. Little minor differences exist (like IPv6 signature support etc.)
Please rate if helpful.
