Cisco Routers :: RV042 Maximum Number Of DHCP Clients?

Jul 11, 2012

I have a few sites using the RV042 with wireless access points and some of them have over 50 devices.In reviewing the documentation (specifically,[URL]), I came across this:Enable DHCP server: Check the box to allow the router to dynamically assign IP addresses to up to 50 connected devices. Uncheck the box if you have another DHCP server on the network or you want to configure static IP addresses for your network devices.Is this accurate?  Or will the RV042 allow more than 50 devices?

Cisco AAA/Identity/Nac :: Multiple Instance Of Custom Attributes ACS 5.x?

Nov 27, 2011

is there a way to have multiple instances of user custom attributes and insert those as multiple instances of the A/V Pair in the authorisation profile in ACS 5.2/5.3 ?Background: We have to migrate a ACS 4.2 to 5.3. In ACS 4.2 our client used the multiline attribute
#Type of Value


to specify multiple routes to various networks in the RADIUS reply spcific for every single PPP username of routers dialing in.Using the internal user database, extended by a string attribute and using that attribute as source of a dynamic value in the access-policy works basically. But as I have only ONE single line instance of the attribute for every user, I can only return ONE framed-route.We have lots of cases where multiple routes have to be assigned to one router.I 'd like to avoid defining a seperate access profile for every remote RAS router for external PPP Dial-In...[URL]

Cisco AAA/Identity/Nac :: 1120 - Registering ACS 5.2 Instance To Primary

May 29, 2013

When attempting to register an ACS instance to a primary (via System Administration -> Operations -> Local Operations -> Deployment Operations), I receive the following error as a popup in my browser:
"This System Failure occurred:  /opt/CSCOacs/db/acs.crt (No such file or directory). Your changes have not been saved.Click OK to return to the list page."
I had 2 ACS 1120 appliances clustered, 1 suffered a hardware failure about a year ago so I replaced it with a VM. That one is now the primary. I'm now wanting to replace the secondary instance (the remaining 1120 appliance) with a VM as well. I removed the current appliance from the network, installed the VM using the same IP address, and attempted to register. It failed as per the above error. After trying this a number of times, I then decided to return the 1120 appliance to secondary status and attempted to register it with the same results as above.

Cisco AAA/Identity/Nac :: ACS5.3 - Configuring Multiple Identity Sources

Aug 28, 2012

I have an ACS 5.3 cluster, that is configured to use AD. There are a few wireless devices, and monitoring tools that do not have AD accounts. I would like to configure ACS to first check AD for the user authentication, and if that fails to roll over to the local (Internal Users) identity source where I can define these user accounts.
It seems that when the authentication hits the initial Identity Policy rule, it never moves onto the next one if the first fails.
Attached are screen shots that show how i'm configured for the test, i have a local user defined and I'm trying to log into the firewalls.
- Identity Definition : Screen shot of the main ACS definition for the rule i'm testing that's not working
- Identity Rule 1 : The configuration of rule 1 that if it fails i need it to move onto rule 2.
- Log Output : Screen shot for one of the failed attempts from the ACS View Log server.
Reason I need to configure it this way is:

- Wireless users authenticate to wireless using AD user accounts. Some hand held scanners do not support that and will need to authenticate using the MAC address.
- Authentication to Network devices for managment uses AD accounts. We have some monitoring tools that do not have AD accounts, and will need to    be able to log into Network devices to issue some commands (Examples: Cisco Prime LMS and NCS, Infoblox NetMRI).

Cisco :: 4402s / Maximum Number Of MACs?

Jun 9, 2011

I tried to add some more MACs to our Controllers through the WCS. I hate mac-filtering. We plan on stopping sometime. Three of the Controllers(4402s) are reporting that we have reached the max which appears to be 506.First, is there anyway to increase this number?Second, if not, any experience with deleting clients? Should I use reporting to find MACs that haven't been used for sometime and delete them? Is there a better way?

Cisco VPN :: 881 Maximum Number Of VPN Tunnels Allowed

Jan 14, 2013

I know this sounds a simple and easy question, but I can't find the answer anywhere - so here it is :-I need to know the maximum number of vpn tunnels that a Cisco 881 can handle.(In context, we have a group of users, who work from home and this office, so their laptops have the cisco vpn client, I need to know how many of these vpn connections the 881 can handle at once before it dies a death.)Hote - I have read somewhere a line that state maximum number of users is 20 but think this was in reference to some VOIP service.

Cisco AAA/Identity/Nac :: ACS5 - Replacement For IP Pools

Jan 26, 2013

I know ACS 5 lacks the IP Pools of earlier ACS versions. I'm looking at a 4 to 5 migration and was thinking of just configuring the IP Pools on the router ("ip pool local" etc) and sending back a RADIUS Cisco Attribute pair with the name of the pool. (Seemed like a neat fix, needs no extra kit, etc.)
I could have sworn that attribute pair existed... but I can't find it in ACS5! What's it's name?! Where is it!? Or have I gone mad!? (And, if I have gone mad, how would you go about fixing it?)

Cisco Firewall :: 5520 - Maximum Number Of Nat Statements

Sep 10, 2012

Is there a cisco best practice on the maximum number of NAT statements on a Cisco ASA? We have a 5520 and a coworker is adding static NAT policies so a vendor can monitor around 1,029 nodes. The problem is each node inside is a 10.X.X.X and to keep the IPs from overlapping with other customers the vendor monitors they would like us to NAT to a 172.16.X.X scheme.

Cisco :: Maximum Number Of Concurrent Connections To 1142 LAP?

Apr 7, 2011

We are having random issues of users not being able to connect to our wireless network consistently. The users will have successfully accessed the network previously but then will have difficulty associating to the network. After a period of time, the association appears successful again. My first thoughts were that there was a restriction on the number of clients that could associate to a given AP at any one time.This is the equipment we have:1x Cisco Wireless Control Server (WCS) Cisco 5508 Wireless LAN Controllers Aironet 1142N Lightweight Access Points (LAP) Is there a hard or recommended maximum number of clients per LAP? If so, where is this defined? From what I have read on these forums, Cisco apparently recommends about 25 clients per AP but I can not find any official documentation to support this.When I go to WCS Home > General > Top APs by Client Count, the top AP reports 20 clients. However, if I click on the AP Name and go to the Current Associated Clients tab, it is only listing 8 clients - why is this?

Cisco AAA/Identity/Nac :: ACS5.1 - AD And RADIUS Attributes Mapping

Aug 18, 2010

I'm trying to dynamically assign  IP address for VPN users from AD (without IAS service). I know that there is a restriction that "Dial-in users are not supported by AD in ACS (note in "acsuserguide51") but Im not exacly sure what can and can't do with it. In "Authorization Profiles" in RADIUS Attributes tab I try to mannually add specific Attribute (Framed-IP-Address).
I have no problem (everything works just fine) with static address assignment in a way as below:

AD is already integrated with ACS and I've managed to download Directory attributes especially msRADIUSFramedIPAddress
When I change "Attribute Value" from static to dynamic type I see  the option to select AD (but "Select" which should list all available attributes is empty)
I know that I can do it directly (ASA <-> AD attribute mapping) but I want ACS to do it
