Cisco Application :: ACE 4710 Context Configured On Bridge Mode
Sep 20, 2012
I have two ACE working on active-standby mode, I have one context configured on bridge mode, with two vlans, the client (vlan 100) and server (vlan 101) sides.I need to balance another service for two servers (different from the ones on the first context ) on the vlan 101, so as the documentation says i can't configure the same vlan on another context because it is already configured on the 1st context as bridge.so my question is the only way i could balance this service is to configure it on the same context??. or there is another way?.These are the design limitations that i have to do this:
1.- I can't change the servers IP address.
2.- The VIP which will answer the clients request is on the same IP network segment as the servers, for example: server1: 192.168.100.125, server2: 192. 168. 100.126, VIP: 192.168.100.124
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 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 have an HA ACE deployment and all seemed to be working well until I tried to access the ACE via the management VLAN in the one non-system context, no go.The ACE is in one-armed mode with an Admin/System context and one user context (named Messaging). Source NAT has been set up in the user context. All VLANs are in a port channel back to the core switches.I can access the ACE via the Management VLAN in the system context, all OK. I can access the load-balanced servers via the VIP in the user/Messaging context, all OK. I CANNOT acccess the managment VLAN other than ping it (resonds to ping, but telnet, ssh, https, etc. fails).The system/Admin context has a default route to the Management VLAN on the core. The User/Messaging context has a default route to the core switches on VLAN 5, which is the VLAN where the VIP resides.If I change the default route in the User/Messaging context to the Management interface on the core switches then I can access both contexts for management, but then the load-balancing falls over and I cannot access the serverfarm (via the VIP). Traces on the rservers show that NAT is being hit on the ACE and the requests are coming from the real IP of the clients. Put the default route back to the User/Messaging VLAN on the core and NAT is back to what it would be expected to be, and then remote/management access to the ACE is gone.
I am looking at management (backup of the configuration) of the ACE 4710 running A4.1, the management software is Cisco Cirrus. The question I have is around the management of the context's, I have a backup of the Admin but would like the user context's also, how this is completed.
We are having issues with our Cisco ACE 4710, it suddenly stopped to telnet admin context.We are able to telnet another context from the same appliance, but unable to telnet the admin context. Is possible to pings the gateways from the other contexts, but we are not able to ping the gateway from the admin context.Actual we have 5 context with the minimum allocation is 10%.ACL and policy map allowing telnet and etc are enable and configured on the interface.
ACE 4710 TACACS issues ,How to setup user with Admin context access permission. I have enable the TACACS and it can directly put me in Context mode not in Admin Context mode .
Can ASA 5510 be configured as bridge mode and still send Netflow info to a collector?We have a PIX connect internal network to internet. Because PIX does not support NetFlow, as a temporary solution, we were thinking of putting an ASA 5510 between the PIX and internet gateway, and configure it as a bridge so that there will be no routing issues, and the ASA can still send Netflow info to a collector.

I am desiging a topology with two Cat 6509 and Two ACE Module, one ACE per Catalyst. I am thinking to use bridge mode for the customer contexts, I would like to know if the Bridged mode is an Assymetric topology.
The server gateway is the ip address of the ACE or the Router?

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.
We have a 6509 with an ACE module. For reasons I don't fully understand the ACE is running using a BVI in bridge mode. It has loads of secondary interfaces.
[Code]...
I can ping all of the IPs on the BVI, but only servers in Subnet 10.7.42/42 can ping out of the the layer 3 on the 6509. I have all the routes configured properly on the 6509 pointing to the ACE for these subnets. The question is though the config has been excepted, is there a limit to the number of secondary on a BVI.
I am trying to setup ACE in bridge mode. Network topology is as follows:
1. ACE Gi 1/2 (client-side vlan) is connected to 3750 (vlan 40) 2. ACE Gi 1/3 (server-side vlan) is connected to 3750 (vlan 50) 3. Two real servers are connected to 3750 (vlan 50) 4. One client device (linux box) is connected to 3750 (vlan 40)
I am not using admin context. I have created a new one for user. I am unable to ping VIP (10.10.50.15) either from client linux box or from within ACE.

I got an ASA 5510 system currently in single context mode, with CSC SSM installed. Single ISP uplink to internet, no VPN. And now customer would like add another ISP uplink, without invest another box for HA.What come across my mind is make the current box into multi context. There's some area i need to concern and also need yours perspective on it.
Question 1: For making the firewall into multi context, am i need to do it from scratch, issue mode multiple command. Then rebuilt the current production config into one of the context, then another context meant for the new IPS uplink, and one admin context?
Question 2: For CSC -SSM licensing requirement, model ASA 5510 with security plus license is able to support 2 context. So if i split my firewall like what i mention in question, what exactly number of context do i own (admin, context A, context B)?
Question 3: For CSC-SSM module in multi context mode, so the management port of CSC SSM must attach at admin context?
Question 4: After configured all the policy and traffic to scan, how exactly i should do in order apply this policy to the interface? Should i only enable at admin context, then firewall service-policy rules, and apply it global, OR should i also do the same action on context A and Context B?
Report run via Individual Web server URL’sThe report takes less than 20 minutes (average 15 minutes) to fetch and return the data. This is observed 9 out of 10 times.Report run via ACE Load Balanced URLThe report keeps on running for more than 20 minutes and never completes. The front end keeps showing report is running.The data in general when tested directly by running queries against the database (bypassing the platform) completes in 15-18 minutesThe network connectivity for each and every ports involved (Loadbalancer/Servers) have been throulgly checked.
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 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 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.
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 already know that ASA 9.0 supports site-to-site VPN in multiple context mode. But remote access VPN isn't supported. Obviously, SSL-VPN is a very important feature for most multi-tenant deployment scenarios where each context acts as a border firewall towards the Internet for each tenant. The alternative to terminate all tenant remote-access VPNs in one context means that each tenant would have to be routable from the ASA, which of course isn't a reasonable requirement in most cases.
So, what I'd like to do is to deploy an ASA cluster, and provide remote access VPNs for each tenant, where the connectivity for each remote access group can be addressed with whatever IP address space, and that goes into it's own VRF in the back-end.
As far as I can tell, this isn't doable with the ASA, since multiple context mode prohibits the use of remote access VPN, and I can't think of any other work-around than either having individual firewalls running in single context mode for each tenant, or demand that all tenants are interoperable routing-wise and configure a separate ip address pool in a single context mode for each tenant.
Essentially, there's no good way to implement this with multiple virtual firewalls, using cisco firewalls?
Is it possible to have context in transperant mode and routed mode. Means if i need three context then 2 of them is in routed mode and one of them is in transperant mode. If yes then how, i can 't find this info in cisco website.?I am havin 5585-x and asa version 8.4?
I would like to know does MSE 3350 supports HA mode,I have 2 M|SE 3350 appliance and I want to configure one as primary and second as redundent for the primary,I am not finding any documentation for the same in the cisco website.
Im looking for some clarification regarding running a Cisco ASA in transparent mode with multiple contexts. To give you an insight into the network design we have the following -
Collapsed Core/Aggregation Layer running Cisco 3750s. The 2 Cisco 3750s are using SVIs with HSRP for default gateways per customer with a total of 8 customers. Each customer is segregated into seperate VLANs with Cisco 2960 switches used in the Access layer. Each customer has 2 Cisco 2960 switches with redundant uplinks to the Core/Aggregation layer. Customers are spanning tree loadbalanced between core/aggregation switches.
What i need to now do is add two transparent firewalls into the mix in either an active/active or active/standby setup. I need the firewalls to support all 8 customers, therefore I am guessing they need to run in multiple context mode. Having read into this it has left me somewhat confused as to how to integrate them into the above setup as a bump in the wire so to speak.
I have a pair of ASA 5520s in active/standby failover mode, single context. I'll be migrating to multiple context mode later this week. Do I need to break failover first? Or if I don't need to, should I? Or can I do this while maintaining failover? Can either of these scenarios will work (or fail). I'll be remote, doing my work via SSH, but have somebody local who can console in if needed.

On ASA 5515 it shows it is in transparent mode and it has multi context.As in transparent ASA we know it has single Management IP address.This ASA is connected to one switch on two ports gi2 and gi3.One port carries vlan say 800 to the ASA.Other port carries vlan 500 from the ASA to switch But when i log onto ASA and do sh run it shows no VLan info there.
