Configuring FT on ACE Modules
Hi,
I am trying to configure FT on ACE modules, with the following commands
ft interface vlan 20
ip address 172.16.20.1 255.255.255.252
peer ip address 172.16.20.2 255.255.255.252
no shutdown
ft peer 1
heartbeat interval 300
heartbeat count 10
ft-interface vlan 20
ft group 1
peer 1
priority 150
associate-context Admin
inservice
The moment I enter the command 'ft interface vlan 20', it gives a prompt that 'interface vlan20 is not associated with ft', how do I resolve this ? Do I need to enable something ?
Hi have the following config which seems to be working fine for me... check your vlan20 interface is up
ft interface vlan 212
ip address 172.31.1.221 255.255.255.252
peer ip address 172.31.1.222 255.255.255.252
no shutdown

Wr mem gives error on ACE module
Hi,
I am not able to save the configuration on the ACE module.
Admin# wr mem
Generating configuration....
Error in generating running config..copy aborted
"Write memory failed for context Admin"
Any help would be appriated.
Thanks
NehaHi Neha,
Kindly check the current system resource usage for each context by entering the #show resource usage
command .
If the resource usage percentage is high, the ACE is overloaded .
Use the copy running-config startup-config command instead of the write memory command. May be it can solve your issue for now.
Write back if it does not sovle your issue.

ft group 2
peer 1
priority 110
peer priority 105

Can you also explain the purpose of configuring an alias IP address on the client-facing VLAN interface? I understand we need an alias IP address on the server-facing VLAN interface to provide a virtual gateway address to the servers. But what's the use of an alias IP on the client-side?
Thank you.
B.Rgds,
Lim TSHi Gilles,
I have configured FT for all user contexts as well as for the admin context. It works. My FT config is identical to the one I posted in this thread. Of course, one has to define the "ft interface vlan" and "ft peer" before configuring FT groups.
I noticed a few things:
(1) After the initial FT config, subsequent FT groups just need to be configured on the active Admin context and it will be replicated to the standby ACE, with the priority correctly reversed.
(2) You will get the message "NOTE: Configuration mode has been disabled on all sessions" when you log in to a standby context.
(3) The hostname of the active Admin context is not synced to the standby ACE. Do you know why?
One issue I encountered in one of the user contexts is as follows:
ace1/ace-context-1# sh run int
Generating configuration....
interface vlan 950
description *** Client-Facing VLAN ***
ip address 10.1.35.5 255.255.255.0

peer ip address 10.1.36.3 255.255.255.0
access-group input ACL_VL951_IN
service-policy input NAT_REAL
no shutdown
This is the active context. It can ping to 10.1.35.4 (alias) and 10.1.35.6 (peer) over VLAN 950 (client-side). It can ping alias 10.1.36.1 over VLAN 951 (server-side) but can't ping to peer 10.1.36.3. The ACL_VL951_IN permits ip any any. Do you know why?
Secondly, I can remotely ping to alias 10.1.35.4 but can't telnet to it (I'm expecting it to telnet to the active context). I have to telnet to 10.1.35.5. Is this normal behavior?
Please advise.
Thank you.

Have any one configure transparent caching on ACE module
How to configure transparent caching on ACE module? Please kindly give me a example configure. Thank you very much.
here is a basic config.
The module will intercept traffic coming in on vlan 20 and loadbalance it doing a url hashing to caches in vlan 30.
The mode is transparent so the destination ip address is preserved.

A problem with ACL in the class-map on the ACE module
Hi all,
I configured the following on the ACE module:
object-group network test
host 192.168.1.21
host 192.168.1.22
host 192.168.1.23
object-group service port
tcp eq www
tcp eq 8080
access-list T line 8 extended permit object-group port object-group test any
I tried to configure a class-map for matching this ACL:
ACE-4710-2/Lab-OPT-11(config)# class-map match-any TEST_C
ACE-4710-2/Lab-OPT-11(config-cmap)# match access-list T
Error: Cannot associate acl having object-group ACEs in class-map.
So couldn't I configure the class-map by using ACL with object-groups involved? Is it the bug or the normal behaviour? Because the customer uses object-groups in ACLs and he has to configure ACL without object-groups for the traffic classification. It is horrible.
Thank you
RomanHi Roman,
I'm afraid it's the expected behavior. You cannot use an ACL with object-groups inside a class-map.

hi,
Is it possible to load balance VIP hits on two ACE Modules in an active/active configuration. Or is it that only per FT group only single context could be active.
Regards.You can have 1 context active on one ACE and the other context active on the other ACE.
If you have 2 Vip, you can have 1 vip belonging to one context and the other vip belonging to the other context.
Like this, you split the traffic between the 2 devices which allows you to handle more traffic than what 1 device could normally do.
If one device can handle all your traffic, I prefer to only have 1 active unit and 1 standby.
Easier to implement and troubleshoot.

Reuse of context in ACE module
Hi all, just have a question about som reuse of resources in a ACE module context. I don't want to make a new context, and can reuse most of the existing configuration in one of my context. The config is not complex and difficult, but I'm not sure if I can do this.
The primary goal is to loadbalance 2 webservers with a new vip, new serverfarm, stickygroup, policy-map and different nat-pool.
Since I haven't decided the ip addresses to be used, they are just xx in the config below.
The changes I want to implement are in bold. Will this work for me?

ACE module - Qos - set ip tos #
All,
Trying to mark traffic to/from L4 rules in the ACE.
Documentation (like always) says it's really easy. Mark traffic by using the "set ip tos <value>" command in Policy/Class configuration. Ok, so I do this, set ip tos 24.
Enable qos globally on the 6500 host, but don't see the traffic being marked.
sh mls qos says that packets are being modified by module 5 (ACE)
But I never see the tos value in any of my captures either via netflow from the host 6500, or at the firewall one hop away.
sh mls qos:
QoS is enabled globally
Policy marking depends on port_trust
QoS ip packet dscp rewrite enabled globally
Input mode for GRE Tunnel is Pipe mode
Input mode for MPLS is Pipe mode
QoS Trust state is CoS on the following interface:
Te3/1
QoS Trust state is DSCP on the following interface:
Gi2/3
Vlan or Portchannel(Multi-Earl) policies supported: Yes
Egress policies supported: Yes
----- Module [5] -----
QoS global counters:
Total packets: 207147888661
IP shortcut packets: 0
Packets dropped by policing: 0
IP packets with TOS changed by policing: 2663386
IP packets with COS changed by policing: 4889352
Non-IP packets with COS changed by policing: 0
MPLS packets with EXP changed by policing: 0
Can someone explain to me what I've got wrong here? Is the ACE simply marking traffic destined for the servers behind it and not the return traffic? Am I missunderstanding something?Well... hopefully someone knows how to classify traffic coming from the ACE.
I've given up on using the ACE to mark traffic as I'm fairly certain it won't do it. At least not the way I want.
However, now I've taken to marking ingress on the rserver switch ports... which has resulted in a partially sucessful solution. Problem is, "partially" successful.
You'll have a bunch of little conversations like this with no tos value full of push-acks:

I think what's happening, is that the conversations full of the P-acks is the load balancer communicating directly with the client (i.e. LB pretending to be the server), whereas the marked traffic is "data only" which the load balancer isn't mangling (like it might/probably is doing with the p-acks) on it's way back to the client.
I also can't modify the configuration of the "virtual ten gig" interface that the 6500 uses as a connection to the ACE module, so can't mark traffic there either. And though I still have a couple of things to try, I don't believe I can do egress marking on a trunk from the 6500 either (connection to the firewalls).
So.... PLEASE... Anyone??? Ideas??? -
Ace module dropping assymetric layer 2 connections
Hi we had a situation in where the ACE would randomly drop certain tcp connections, and all ICMP packets from a certain windows server. The server in question was using Transmit Load Balancing with Fault Tolerance.
The server has one Nic connected to Access switch1, and the other nic connected to Access switch2. Each access switch connects up to a pair of 6509's, which is active on Core1 on both switches.
I am guessing If the server sends on Nic 2, core1 knows it came in on the downstream trunk port to Switch2, it must reply to these packets based on the teamed mac of the layer 3 address(no idea who is arping for the destination - the ace?), and send them back out the downstream trunk port to switch1. The ace module is in transparent mode. When contacting a server on the other side of the ace, the ace drop packets that came from the second nic - and I am wondering how it "knows" that the return path is out of different downstream port. Does it share some kind of layer 2 RPF check with the 6500 ?
Please note there is no routing involved here. The destination server is just on another vlan on the same subnet, on the other side of the ace.Bryan,
As long as the server replies back to the ACE the client should only be commmunicating with the VIP address in either of your two examples.
In your first example the flow will look like this.
client > VIP after the ACE client > rserver
the reply would be
rserver > client after the ACE VIP > rserver
In your second example using client nat it will look like this
Client > VIP After ACE Natpool > rserver.
the reply would be
rserver > Nat-pool after ACE VIP > client.
The ACE by default will always nat the vip to the server ip unless you use the command "transparent" under the serverfarm. When using this command we send the packet to the MAC address of the server leaving the destination IP of the VIP. The server would need to have the VIP address configured under the loopback interface.

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
class WEBMAIL-80
appl-parameter http advanced-options HTTP_ADV_OPT
loadbalance policy WEBMAIL-80
loadbalance vip inservice
loadbalance vip icmp-reply active
nat dynamic 1025 vlan 436
class WEBMAIL-443
appl-parameter http advanced-options HTTP_ADV_OPT
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
loadbalance vip icmp-reply active
class WEBMAIL-443
appl-parameter http advanced-options HTTP_ADV_OPT
loadbalance policy WEBMAIL-443
loadbalance vip inservice
loadbalance vip icmp-reply active
class class-default
nat dynamic 1025 vlan 436

Certificates vanished - ACE Module. Strange!
ACE modules are configured in Active/Standby context mode on two distinct Cat6500's. The feature license is 10,000 SSL tps, 8Gbps throughput.
We ran the application performance tests with 1000 users with https transactions and I noticed that the all the root certificates under the chaingroup disappeared. Only the website certificate remained. When I accessed the website, it gave 'error with the security certificate' i.e. the root was not identifiable due to missing certificates. Eventually, the CPU went 100% on Cat6500 and the ACE module was shutdown by the chassis. It got reenabled automatically in 5 minutes.
I re-added the root certs, removed/added the service policy and after sometime I noticed the root certs disappeared again. STRANGE !

How can I configure ssh management access to the ACE module configured in bridged mode.
do not mix "domain" name and user "domain".
The domain name is something like cisco.com or yourcompany.net ...
But the user domain is what objects is a user allowed to modify/configure/access inside ACE.
I don't think you need to specify a domain-name to generate the key.
Here is what I did :
switch/Admin(config)# ssh key rsa 768
generating rsa key(768 bits).....
generated rsa key
switch/Admin(config)#
gdufour-cat6k1#ssh -l admin 10.86.213.40

Hi,
I configured a new serverfarm with leastconns predictor for two servers on our ACE module Version A2(2.3). Probes (show probes XX detail) to the servers are successful and both servers are operational (show serverfarm APPLI detail) but connections are directed only to one server.
When I deactived the server which is receiving the connections (no inservice), the ACE start to direct connection to the second server.
There are several serverfarm, configured the same way, that are Loadbalancing traffic as correctly.
Here is a sample of my config
serverfarm host TEST_443
predictor leastconns
probe TEST_443_PROBE01
rserver TEST_RS01 443
inservice
rserver TEST_RS02 443
inservice
sticky http-cookie TEST_HTTPS TEST_443_STKY
cookie insert
timeout 720
replicate sticky
serverfarm TEST_443
probe http TEST_443_PROBE01
port 443
interval 20
passdetect interval 60
passdetect count 5
request method get url /test
expect status 302 302
connection term forced
policy-map type loadbalance first-match TEST_L7PLB_HTTPS
class class-default
sticky-serverfarm TEST_443_STKY_SF
insert-http X-Forwarded-Proto header-value "https"
insert-http X-Forwarded-For header-value "%is"
policy-map multi-match SLB-HTTP-POLICY
class TEST_L4VIP_HTTPS
loadbalance vip inservice
loadbalance policy TEST_L7PLB_HTTPS
loadbalance vip icmp-reply active
loadbalance vip advertise active
nat dynamic 1 vlan 202
appl-parameter http advanced-options PERSIST
ssl-proxy server TEST_SSL_PROXY_SERVER
PS : ACE uptime is 291days, could that impact ACE behavior ?
Thanks for any troubleshooting hintsLooking at this on my phone but it looks like you L7 policy is referencing a sticky server farm that does not exist.
ie TEST_443_STKY_SF is incorrect name for sticky
If that's not it. Then check that the first server actually has a number of conns on it when a new connection is established. Sometimes when both servers have 0 conns - new incoming conns will always go to the first server
