ACE module routed mode
Hi,
I have a scenario where I have a pair of 6509 switches and I need to add an ACE module on both of them. All clients Default gateway are on internal 5580 ASAs so there are no SVI interfaces on the 6509 switches, it's only doing layer 2 switching.
I need to add an ACE module to the above setup, what's the ideal scenario in terms of routing without having to modify and add SVIs on the 6509?

My first question, can anyone recommend some very heavy reading discussing the ACE modules and associated traffic flows and order of operations? Not just how-to scenarios.
And the primary question that brings me here:
I've got an ACE module in a 6500 chassis that's configured for routed mode. For the purpose of this question we'll say that on the ACE I have a single VLAN for vIPs and a single VLAN for rservers. vIP VLAN is 12 and rserver VLAN is 101. I have a pair of App servers being load balanced, and a pair of Web servers being load balanced.
When user devices send traffic to the Web servers vIP, traffic hits the SVI for VLAN 12 and the service-policy is applied manipulating that traffic and sending it to the VLAN 101 SVI and on down to an rserver. The same if user devices are sending traffic to the App servers vIP.
When a Web server tries to send over to the App servers vIP, I get no response. In fact, from the Web server I can't even ping my gateway (SVI for VLAN 101). How do I get the Web server to send traffic loadbalanced across the App servers?
Here's an example ACE config:
access-list ALL line 8 extended permit ip any any

You can check Gilles' DC t-shooting guides that should give you a very good overwiew about packet processing on the ACE; also you can check
the Cisco wiki site where you find the scenarios plus a detailed explanation for traffic management.
Now going back to your issue, you problem can be splitted in two parts.
1. Web server not able to ping VLAN 101 ACE's SVI.
ACE is a closed device, meaning that access to each Interface/VLAN needs to be explicitly configured; you need to apply the management policy
to the 101 SVI to allow ICMP or any other management protocol. You can apply the same (service-policy input MGMT-ACCESS) or create a new
one just for ICMP, that's up to you.
2. Web servers not able to communicate with APP servers thorugh VIP.(vise-versa)
Problem here is that servers are trying to communicate through SVI 101 but no VIPs are applied to it so the ACE will simply discard the packets
for 10.10.12.20/10.10.12.21 on that interface, servers have the ARP and everything to reach those VIPs but the ACE has not been instructed to do
load balancing for clients reaching it out through VLAN 101.
In order to do load balancing between APP & Web Servers you need to configure L4-CONTEXT-A-VLAN on SVI 101 as well.
Also since your servers are sitting all in the same VLAN you're going to need client NAT to prevent assymetric routing on server-to-server communications.
I've attached a sample with NAT based on your config.

Hi all,
I have a requirement to install 2 ACE Modules into two 6509 chassis'
We want to run the ACE modules in a live/live scenario so we can utilise the two ACE modules
So we want to split the VIPS so we have some live on one ACE and others on the other.
Also the ACE modules will be setup in routed mode. We have a number of subnets we want to use on the client side - 3 to be exact, and there will be another 3 different subnets on the server side
A few points which are confusing me
For each subnet would i have to configure a SVI? And if so you can only have 1 SVI per contect so that would mean creating a context and a SVI for each subnet?
Are there any example configs which could help me out?
Any help would be appreciated
Thanks
JamesSee the config example here:
http://www.cisco.com/en/US/products/hw/modules/ps2706/products_configuration_example09186a00809c3048.shtml
Normally you only need one client-side subnet per context, but multiple ones work too.
You'd create an SVI on MSFC for the client-side subnets only, otherwise server traffic would bypass the ACE.
Also keep in mind when you do active/active, it's done on the context level.
That means you need to create at least two contexts in addition to the Admin context. (although you can technically run things in /Admin)
Go through the example above, and the config guides below and you'll be all set:
http://www.cisco.com/en/US/products/ps6906/tsd_products_support_model_home.html -
ACE bridge mode , FWSM routed mode
i have the following senario:
MSFC ---vlan 777----FWSM----vlan160---ACE----VLAN180
FWSM is working in routed mode and vlan 777 is shared between the MSFC and FWSM
ACE is working in bridged mode and vlan 160 is shared between the FWSM and ACE
vlan 180 is the server side vlan
i want he FWSM ip address to be the Server gateway while ACE module in
bridge mode
i create bvi interface but i can't ping from ACE to FWSM or from FWSM to
ACE
if i change ACE to routed mode , i can ping to FWSM
any body can help me in this issue?The config looks good.
I would look at the arp table on FWSM and ACE when the ping fails and also capture a sniffer trace of ACE tengig interface and see if the ping request goes out - on which vlan - and if we get a response.
Is evertyhing else working ?
Like ping through the ACE module ?
Your config does not show a 'no shutdown' on the vlan interface, but I assume you fixed that already.

Ace routing mode desging issue
need some assistance in configuring an application using routing mode on cisco ace
clients ---asa--3750--cisco ace--- servers behind vip
|
visa card transaction servers
i am able to setup a vip on ace using routing mode on ACE,as the servers need to see the client ip ,so we are not performing SNAT,this part is working fine
when a request comes from the client ,it goes to the vip and to one of the backend servers ,and the request will be forwaded back to the ace ,as the default gateway on the servers is pointing to the server vlan on ace.
but if the transaction from the servers need to go to the visa card transaction servers ,how can we acheive this ,and after fetching the data from visa servers,does the reply will be fwd to the ACE or ASAs directly
Or do we need to have static routes defined on the visa servers to point to ASA
please advise me on thisClint
No they are completely in a different network ,
When a client hits the VIP ,the request goes to the ASA
ASA fwd the vip traffic to the ACE (VIP) interface ,and from there it fwd the traffic to the (server vlan) interface and to the appropriate backend servers.
Backend server responds back to the (server vlan ) interface and the traffic fwd back to the ASA.
But when visa card transaction need to take place ( farm servers ) need to route the traffic to the visa servers which will be in different subnet range .
Do the farm serevrs send the request back to the ASA and can we configure static routes on ASA to point to the visa servers.
Are on the farm servers can we have static routes for the visa servers
Or can I defind static routes on ACEs for the visa servers. -
I am configuring ACE in routing mode ,
Below is my ACE interface config.

When I configuring my servers in vlan 29 and point the default gateway to 192.168.10.19 it works fine no issues,but when this ACEs goes down and the standby becomes active ,my servers default gateway will be still pointing to 192.168.10.19 do i need to manually change it .20
or can I configure HSRP,Please advise me on thisHi ,
Yes the alias should be set as gateway for the servers.
The alias is a shared address between the peers. This address will be on the ACTIVE ace.

ACE in bridged mode and multicast
We have configured an ACE SM in bridge mode and have a requirement to enable multicast on one of the networks where the back-end servers are residing. Will ACE support multicast out of the box, or will we need to do any tweaking on the ACE to enable the multicast support?
Thanks..Hi Gilles,
Is it also supported in routed mode?
The ace isn't doing multicast routing right?
Actually, the server-side vlan is being routed on the C6500 and has pim sparse-dense mode enabled.
We want to move this server-side vlan behind the ace in routed mode. What about the pim?
Any ideas?
thanks,

Hi,
i have a topology where i have to set up an ACE in routed mode with two context. one for service provider A and one for ISP B.
what i want to do is when i receive a request coming from service proveder A i would like to SNAT that request to de VIP with a specific IP of the servers LAN to hide the source IP of the cliente in that way a can receive the request on the server with a local IP and the resever can respond to that IP.
in the same way to handle traffic on the second ISP.
i have try to set up the configuration in the same way it would work in one arm but it has not worked out for me.
is there a guide to follow or if someone can help me whit this config.

Hi,
We have migrated CSM to ACE Module recentlym all the applications are working fine. But one of our real server , Hosting team did NIC Teaming (Active-Active) which was working fine but not with ACE Module (Briding Mode).
My assumtion is because of ACE in Bridge mode all the non-loadbalancing traffic has to go through ACE Module, So we couldnt access the server directly. If ACE is in One-armed mode i think it should be fine.
But with bridge mode do we have any option to make it working.there is a restriction regarding NIC teaming in active/active mode.
The ACE uses an hardcoded mac-to-IP mapping with ARP. As with active active nic teaming you'll have 2 different mac addresses, the one which is not present in the ARP cache of the ACE is considered as a security violation. -
Hi
In the Datashhet of the ACE-Module (ACE20-MOD-K9) there is the following promise:
Throughput
16 Gbps*, 8 Gbps*, and 4 Gbps
We have a base license, so I assume we have a throughput of 4Gbps (gigabits per second).
Are these 4Gbps bidirectional or unidirectional?
Is it 2Gbps in one direction and 2Gbps in the other direction?
Imagine we have just 1 host (A) before the ACE module and just 1 host (B) behind the ACE module. Can I transfer data from A to B (unidirectional) with 4Gbps? Assume the hosts are connected with 10Gbps to the network and use multiple flows!
How can I measure the effective used bandwith on the ACE module?
What hapens, if host A tries to send data faster than 4Gbps? Does it deny single packets? Base on what? Does it deny additional sessions?
How do I know that the ACE runs at it's bandwith limitation?
Any Ideas?
Thanks
PatrikHi Patrik,
See my answers inline:
We have a base license, so I assume we have a throughput of 4Gbps (gigabits per second).Are these 4Gbps bidirectional or unidirectional?Is it 2Gbps in one direction and 2Gbps in the other direction?
It measures the total throughput going through the box. It includes both directions. Also take into account that, for any traffic through the ACE, the packets are seen twice (client to ACE and ACE to server), so the effective throughput is half of the licensed one.
Imagine we have just 1 host (A) before the ACE module and just 1 host (B) behind the ACE module. Can I transfer data from A to B (unidirectional) with 4Gbps? Assume the hosts are connected with 10Gbps to the network and use multiple flows!
You could get up to 2Gbps unidirectional. This traffic will go through the ACE twice, adding to the 4Gbps license
How can I measure the effective used bandwith on the ACE module?
With the "show resource usage" command
What hapens, if host A tries to send data faster than 4Gbps? Does it deny single packets? Base on what? Does it deny additional sessions?
It will drop packets that go over the bandwidth without taking into account to which connection they belong
How do I know that the ACE runs at it's bandwith limitation?
Again, "show resource usage"

Sharing a VLAN between FWSM and ACE (Routed Mode)
Anybody in here with experience on sharing a Vlan between an ACE and a FWSM module?
I have a transfer network between the ACE and the FWSM in the same chassis. FWSM gets several vlans and ACE gets some Vlans.
I wanted to configure it like this.
firewall vlan group 10 <FWSM only vlans>
firewall vlan group 20 <shared FWSM and ACE vlan>
or
svclc vlan group 20 <shared FWSM and ACE vlan>
svclc vlan group 30 <ACE only vlans>
The design hides the client side network and the server side network for the ACE behind the FWSM module.
Layout:
|-- Clients <--> MSFC <--> FWSM <--> ACE <--> Server --|
So allocation on the 65xx would be like this.
firewall module n vlan-group 10,20
svclc module n vlan-group 20,30
Any obvious issues with this design if you share the vlan(s) referred in group 20 with both modules?
FWSM and ACE will be in routed mode.
Thanks for reading...

Can VIP and Rservers be in the same subnet in ACE Routed Mode
Good Day,
Sorry for the lengthy post.
Currently I have a 6509s running in VSS mode with ACE30 in each chassis.
I have 5 vlans, which the VSS is the L3 interface for each. 1 Vlan is for management, the others are the data vlans for the servers.
The ACE is configured in bridge mode, with all VLANs going to a specific context (non Admin).
Some of the Host on each VLANs are not utilized for load-balancing. The default gateway for each VLAN is configured on the VSS.
I would like to setup the ACE in the routed mode, without having to change the IP address of each servers on different VLANs.
Basically I want to turn off the SVIs on VSS and move the L3 interface on the ACE Context, and let it perform the local routing for all the hosts.
I was going to add a new /30 L3 interface between the VSS and ACE to be utilized for default route traffic coming from the ACE Context, and static routes from VSS to ACE for traffic destined to host that are being load-balanced and not being load-balanced. Basically force the traffic through the load-balancer in/out.
For future deployment, I was planning on using different IP address for the VIPs, and Real servers (most likely RFC 1918).
From most of the examples I have seen the VIP and Rservers are in different Subnets. But because I am trying to not change the IP address of the rservers and VIP, I wanted to know if the VIP and Rservers can be configured to be in the same subnet where the ACE is in routed mode.
Unfortunately I don't have a spare ACE to test scenario.
As always any help would greatly be appreciated.
Regards,
RamanLink-local addresses are usually the self assigned IP address that a device will set when a DHCP server cannot be found. These are the addresses with 169.254.x.x subnet.
If the router is assigning IP addresses for your network, then they will usually have a different IP subnet, possibly 192.168.0 for D-Link. And this subnet would be for the wired and wireless connections. So it would be more a case of bridging the two network topolgies rather than routing them.
The network host is busy message could be more to do with the driver and the IP protocol selected when creating the queue than the connection being broken between the Mac and printer. If you were to open Network Utility and select the Ping tab, enter the IP address of the HP and set the pings to 4, pressing the Ping button will soon show if there is a path through the wireless to the printer.
If you get a response to the ping you could then open Safari and type the ip address as the URL. This would then connect to the internal web page of the printer and possibly let you enable an IP protocol like LPR so that you can use LPD on the Mac instead of Bonjour to connect to the printer.
As for the driver, you could look at using a Gutenprint driver instead of the HP driver or the hpijs package to get past the limitations that some printer drivers have with network connections. -
Ace module in bridged mode with client nat
Could someone confirm whatever a NAT is supported for ACE-20 module, please?
Let me to explain technical details.
I do need to convert working CSM(SLB) config to ACE configuration and I am not quite sure
if the configuration below is correct. ACE module should be configured in bridge mode with two
vlans - vlan 36 (client) and vlan 436 (server) - bridged with interface bvi 36.
NAT on ACE configurad as "nat dynamic 1025 vlan 436" into corresponding
"policy-map type loadbalance"
Could you check two parts of configs and advise me if the ACE config is
properly converted from CSM and will be working in the same way (especialy for NAT).
Thank you in advance.

You will want to use PAT while you do nat, so change the natpool configuration to this:
nat-pool 1025 10.36.3.100 10.36.3.100 netmask 255.255.255.0 pat
You also need to apply the nat like this:
policy-map multi-match IFVLAN36-POLICY

loadbalance policy WEBMAIL-80
loadbalance vip inservice

loadbalance policy WEBMAIL-443
loadbalance vip inservice
loadbalance vip icmp-reply active
nat dynamic 1025 vlan 436
If you are going to build out a lot of classes, you can instead do source nat like this:
policy-map multi-match IFVLAN36-POLICY
class WEBMAIL-80
appl-parameter http advanced-options HTTP_ADV_OPT
loadbalance policy WEBMAIL-80
loadbalance vip inservice

Design question: ACE module connected to 2 different L3 engine while in bridge mode
fellow engineers,
i have been working on a design model , where the ACE mldule will provide SLB for both virtual and real servers. we have been deploying several UCS systems and the customer would like to use the ACE as our Enterprise SLB layer
configured in bridcge mode.
the msfc within the 6509 provide the L3 routing. however we may extends multiple vlans (v160-v163) via nexus switch layer (7k,5k,2k) to a FW appliance which now is the svi interface for the extended vlans. these vlans will be configured on a dedicated context.
the extension is based on the bridge mode operation as follow:
need help with the following:
1) if i have 4 bvi's configured, do i need to have default route configured?
2) my total count for vlans are: v160-v163 for server vlans, and v101 is the management vlan. the svi for this vlan is on the msfc card. the server GW are pointing to each dedicated svi's on the FW+L3 apliance.
3) if my default route on the context is pointing to the v160 svi on the FW+L3 engine, will that prevent the return traffic for other vlans ( v161-v163) from the ace toward the client?
4) is default route neccessary if you hae the ace in bridge mode.
it was brought to my attention that if you have multiple vlans configured in bridge mode pointing to another L3 engine, then each vlan would have to be configured on seperate context since you can only have one default route per context.
i appreciate any feedback on this inquiry. if you need additional information please le me know.
thanks and best regards,
raman azizianHi Raman,
You can have up to eight default routes in one context. What the ACE is doing with the entries is to create a ARP-entry with the name GATEWAY. If you need more then eight entries, just declare gateway as rservers. In that case the ARP-entry is stored as RSERVER instead of GATEWAY. The trick is to tell ACE to learn the MAC-address for the IP-address and store it int the ARP-table. The ACE never learn for itself a MAC-address. Don't forget mac-sticky enable on vlan's facing gateway.
I'm running one context in bridge mode and have 18 bvi's with FW and Router 6509 as gateways.
Exampel:
Interface to ROUTER 6509
interface vlan 300
bridge-group 300
no normalization
mac-sticky enable
access-group input BPDU
access-group input alla
access-group output alla
service-policy input lb-int-vlan300
no shutdown
rserver host 300GATEWAY
ip address 164.135.121.47
inservice

ACE MODULE IN BRIDGE MODE NOT LOADBALANCING
Hi,
I setup an ace module in bridge mode as follows:
mfsc(vla80) > (vla80)outside fwsm, fwsm inside(vla40) > (vla40)ace-clientside, aceserverside(vla41)
and the servers have the fwsm svi(vla40) as their gateway. But, the ace is not loadbalancing.
The config script is attached. Is their anything I am missing?
AttachCheck my troubleshooting guide on this forum.
There are few things to do to narrow down the issue.
