We are using Cisco ACE 4710 for load balancing the servers. The predictor used is 'least connections'.Have observed the below;The number of connections for a particular server in a serverfarm is 15 in the Cisco ACE.The actual number of users in that server is 6.All the users access using the VIP.Still i couldn't understand why there is difference in the number of users in the server and the load balancer statistics.
I am configuring a load balancer from cisco, a ACE 4710.Load blancing is completely new to me, and i am unexpereinced in this field. It has to be configured for a customer that want to load balance HTTP and RTSP traffic over 4 application servers (Back-end),I searched alot on google for possible solutions, and got RTSP in some way to work, but http wont work says my customer.
how to capture the incoming and outgoing packets on the balancer?The load balancer is connected in between the customer DCN and cisco switches 2960.The reason of capturing both incoming and outgoing packets on the balancer is to prove to our customer that there is no packet loss issue on the balancer, and it could be some issue on their DCN network.Since it is a production server, I will need to ensure that there is no impact to the incoming and outgoing traffic on the balancer and other networking equipments as well.
We have a CSS 11503 with the following partial config [code] it is clear that the server at 10.10.10.222 is active. What we cannot understand is why web site is inaccessible thru load balancer using http://10.10.10.1.
I have got Linksys RV082 in my home network to use it as load balancer between 2 providers.Is it possible to make some customisation in scenarioses and logging system? As I understand the device is based on some Linux core and Linux infracrtucture. So it must me available in sources... How I may get this kind of access? I want to get ssh/telnet or other raw access to installed on the device OS and manual control it, treat around web-UI. How may I do it?
Is it possible to use 1 or 2 of the 4 gigabit ethernet ports from one ACE straight into the other ACE for redundancy? So ACE_01 gig0/4 to ACE_02 gig0/4.If so, is it a case of just having the layer 3 config instead of trunking etc..Also - is it possible to create a context within the same vlan as the Admin context?
I have two ASA 5510 in an Active/Active failover configuration; On the first ASA I have a license for five security contexts, on the second one I have the default two. On the pair I configured seven security contexts and everything works as expected; so far so good. Let's suppose now that the first ASA (the one with the license for 5 contexts) goes up in smoke; all the contexts migrate to the surviving firewall and life is still good. But what happens if, for some reason, I need to reboot the second ASA before the first one is repaired? My guess is that it will come up with just its own license for two contexts and that I will not be able to operate all my virtual firewalls.
I'm currently running CiscoWorks LMS 4.0.1 on Windows 2003 under VMware and just got upgrade licensing for Prime Infrastructure 1.2. I am assuming that I will need to upgrade the current server to Prime LMS 4.2 in order to ensure that data migration to Prime Infrastructure goes well. I am planning to follow Cisco's recommendation to run Prime LMS and Prime Infrastructure in parallel for a time and migrate individual functions.
My real question is about Syslog handling. All of the managed devices are currently sending Syslog data to LMS. As a last step in the migration, is it possible to change the IP address of the Prime Infrastructure server to replace the Prime LMS server so that the Prime Infrastructure server will just start getting all the Syslog data, or do I need to go change hundreds of managed devices to point to a new address?
Lately we have been comsidering an upgrade in our organization involving a 1921 router. The main role it will play is a load balancer/failover between 2 connections from 2 different ISPs. what additions are required to be added to this piece of equipment to make the configuration work. Im researching the matter now and it seems an extra card whould be purchased in addition to the router. Also, i cant seem to find much information on the available licenses to go with the router. will i need a special license to utilize the balancer/failover feature? (ip base, data, SEC).
trying to get my ducks in a row for replacing a Cisco 5510 and a Barracuda Link Balancer with a virtual pfSense appliance. This is partially due to eliminating support contract costs (nearly $3k annually between both appliance) and partially to utilize the redundancy and fault tolerance that our virtual environment can provide. I'm also implementing a colo site for replication/DR this year so doing a tunnel from site to site would make it a lot easier with like for like virtual appliance firewalls.
The VPN aspect. We are currently doing Cisco VPN with Radius auth on the back end, this is seamless to setup from an end user perspective as they just hit a URL, download/install the ANyConnect client, and log in with their credentials. Is there a comparable alternative in pfSense? I'm leaning toward IPsec but it still doesn't seem as seamless as what we currently have in the ASA.
I don't have an ASA to lab this up on, and having read through the literature I have available to me I'm not sure how this would work but here's where I am at the moment. Situation: One ASA, two contexts, no shared interfaces, no 'hairpinning' to another common device like a router or layer 3 switch.Requirement: The ASA will separate two security zones. Each zone must be independent of the other (no shared interfaces).Expectation: Traffic to be enter the sole interface in context A, then be internally directed to context B before being dispatched out.
I face an issue while creating source nat on cisco ACE. There is already a default source nat ip for the context. I created a new one for smtp traffic alone. Iam facing issues in prefixing the newly created nat-pool rule(nat-pool 100) above the default one (nat-pool 2257) on the external gateway interface as its not placing that on top ,due to which only the default snat ip is getting shown on all servers.
I know most QoS capabilities aren't available in multiple context mode, but I need to do some really simple policing on one of my contexts. I just want to apply a hard 20Mbps cap on an interface. I've seen a few places that suggest that basic policing is possible in multiple context mode, but apparently not by the normal commands.
I Just deployed some of these new modules and running A4.x code. How to configure an ACE with the maximum context?
We run in tranparrent mode with 110 Contexts, we found that with a base config for each context(80 lines of code) this would only leave us with 7% of available RAM. The Device begins to shut down services @ 5%. like SSH and others.
So, Is this even possible to configure 250 contexts and still manage the device.
I need to upgrade 2 active-standby cisco ACE4710, the issue is I cannot access FTP/TFTP/SFTP server via Admin context but can be accessible via other contexts.
Can I copy the ACE system software file from FTP/SFTP/TFTP server to image: directory durectly or need some other way around ? I could see the option is available to copy ftp: to image: via other context.
I am currently working with ASA 5585 with several contexts. What is the percentage of the CPU used per context. I already have the opportunity to do it for the whole ASA (context admin) using the SNMP mib CISCO-PROCES but, unfortunalty, this mib doesn't allow us to know the percentage of used CPU per context.
I was able to know the number of core used per context but not the percentage of the CPU used.
We have a pair of cisco Asa 5520 currently running multiple context mode. We wish to change to single context mode for following reasonWe will migrate infrastructure to hosted vendor . I was thinking of configuring site to site . Current Asa we pal to kee since wireless sits in our DMz and we have net screen that hosts tunnel for erp1. Is context change required for running site to site2. Is it a good idea for creating site to site on to make sure wireless network and oracle traffic goes through managed firewall ?
I've got an ASA which has a number of contexts. They all share the same external interface, and in the interest of saving addresses I'm wondering if the standby address for each context is really necessary. I know that in active/passive the standby address is what allows the two to communicate and monitor that particular interface, however, in active/active I don't see the point as the context is either going to be on one or the other.
We have ASA configured in multi context mode, with software 8.4(2) configured for AAA Configuration is admin context as follows:
aaa-server TAC protocol tacacs+ aaa-server TAC (management) host 10.162.2.201 key ***** aaa authentication enable console TAC LOCAL aaa authentication http console TAC LOCAL aaa authentication serial console TAC LOCAL aaa authentication ssh console TAC LOCAL
Because of multiple context, after logging in we enter System context. Console port authentication is working fine except access to privileged mode while connecting over console port. After issuing "enable" command ASA accepts only configured enable secret in system context and changes user ID to enable_15, so we are unable to do user-level command authorization and accounting.It seems that ASA in system context is not aware of any AAA configuration, and there isn't any command to configure AAA in system context.Is there any way to configure enable authentication over AAA in system context?
I am looking to deploy a cloud/borderless network solution and cannot get my head around how the licenses (AnyConnect Mobile and essentials) will be applied in a multiple context deployment. Any correct documentation.
Firstly is this the right forum to post threads about FWSM's. We have 2 FWSM's in two seperate 6500 switches. There are a number of contexts on each FWSM.I want to fail a context from one FWSM over to the other 6500 and FWSM. Can you tell me how I can do that? Do I need to do it in the admin context and do I need to do it on the admin context of each 6500?
I have a ASA 5510 and planning to implement multiple context in a 2 tier security level and vrf-lite. meaning I have 2xASA facing the internet and below that a 2x3560 switch for our extranet and below that is another 2xASA for intranet. See diagram below. In this kind of network I want to know how it would impact the total throughput and resources of the ASA using multiple context?
I have just joined a networks team and will be working on two fwsm versions 4.0(8) in two 6500 routers. Now the fwsms seem to be virtualised with multiple contexts. The server team want a new context setup for a group of servers behind a vlan. [code]
This context just seems to have two Vlans and a BVI interface. What is the function of this context and why we have 2 admin contexts?
Also another important question is on which 6500 do I create the new context? Is the admin context active on one 6500 just like other contexts and will sync across or do I have to create the new context on both 6500s.
