ACE module connection drops

I am facing an issue with Cisco ACE module. Have 5 servers serving the connections for applications. However, during peak hours there is lot of dropped connections.
Also have lot of fragment reassemble.
Please help how to go ahead troubleshooting the issue.

it is on the cisco site. In the ACE datasheet to be exact. But I'm talking about the appliance. Not sure about the module. But should be the same. Only thing I was not sure was whether the same limits apply to the base license package, or are the figures lower for the base license. Cisco says that the numbers are the same for the base package.
however I'm yet to verify it on the field

  • 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 azizian

    Hi 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

  • 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.

  • Cisco ACE module missing licence file - no connectivity

    Hi,
    We have 2 ACE modules that were delivered without any licenses.
    There is no IP connectivity whatsoever to these modules and I'm guessing this is due to the fact there are no licenses installed.
    Have tried asking Cisco to no avail - and am not sure if there is an actual problem with them or not.
    The VLANs are assigned correctly and I can see inbound ICMP echo from the 6509 that its hosted in, but no outbound packets ever leave the ACE. I've applied a mgmt policy to enable ping/telnet/ssh etc.

    Total arp entries 4
    The ARP table for the adjacent switch SVI has a valid MAC upon reboot, but soon after resets to 00.00.00.00.00.00
    Problem is that once Cisco eventually send me the license file I have no way of TFTP'ing it to the ACE module.
    Any suggestions/advice?

    Thanks for the info - so I should at least be able to connect to a license-less ACE at least, but these modules seem to have a problem.
    If the modules are reloaded (from the ACE) or reset (from the Supervisor) they initially have the ARP entry (however still cannot communicate to the attached Supervisor via SVI) which eventually resets.

  • ACE Module and Limiting Connections

    We currently use the ACE module to Load-balancing IPSEC connection into SPA's.  Since the SPA's only support 60 new connections per second.  I was looking for a way to limit the amount of connecitons from the ACE to the SPA's.

    Hello,
    Have a look at the Configuring Real Server Rate Limiting section of the ACE documentation.  I think this will meet your needs.
    Hope this helps,
    Sean

  • ACE Module Cookie Parsing causes Reset Connection

    I am trying to upgrade my ACE Modules from A2(1.3) to A2(3.2) . Unfortunately, the cookie parsing breaks when there are illegal characters and causes a connection reset (RST) when there is an invalid cookie, but only on code later than A2(1.3).
    The cookie in question is being passed by a third party so making them change the cookie is not necessarily do-able. The cookie has the following value:
    Cookie:  CurrentUser={"UserKey":{"Key":"anonymous"},"LastUpdated":"10/13/2010 1:35:52 PM"}
    We are using the following parameter map:
    parameter-map type http CASE_PARAM
      case-insensitive
      persistence-rebalance
      set header-maxparse-length 20480
      length-exceed continue
    On the older code, the request is passed on to the server.
    Is there a setting similar to "length-exceed continue" that I can give the ACE to tell it to ignore cookies it cannot parse?

    HTTP inspection is not enabled.
    Did you mean adding a class-default to the policy-map?
    Adding it to the policy-map does make it match the class-default. Unfortunately, cookie parse errors result in the inability to parse both the cookie and the host header as well. It seems that rather than just failing to parse the cookie and being unable to do sticky matching - it completely fails the entire header parsing.

  • ACE Total Connections Failed stats

    I have been monitoring connection stats on an ACE Module context (show stats connection).
    During recent load testing I observer that about 1/3 of all connections were failing and some timing out.
    How can I find out more details about the connections that are failing and timing out?
    ie which specific connection are failing, what type of failures increment this counter, etc
    Cheers,
    Karl

    Hi Kim,
    Thanks for responding.
    A load test was run earlier today. I cleared the counters and collected some stats (see below).
    I also had a look at various other stats for drops.
    As far as I could see all relevant, rservers, serverfarms and service-policies were:
    in service BUT
    drop stats were not incrementing at anywhere near the same rate as the Total Connections Failed stat.
    Another load test is scheduled for tomorrow.
    Any thoughts on what to check next?

  • 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???

  • Simple SLB with the ACE Module

    But there seems to be some Problems with the Loadbalancing i not understand:

  • ACE Module throughput

    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
    Patrik

    Hi 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"
    Regards
    Daniel

  • Wifi connection drops down. [SOLVED]

    Hi, I'm having some issues with the wifi, in my notebook lenovo b5070. The main problem is that the connection drops down after 20, 30 minutes. I tried to change from NetworkManager to Wicd, but that didn't change anything. I also tried to create a profile and connect me through netctl, but again that didn't change anything. Other issues that I'm having are: Sometimes I can't even connect to the wifi, or if I can connect finally, and I try to request some website, the browser keeps idle and finally shows a "Server not found" message. Also the wifi signal seems pretty fine. I also tried change the tx, rts to the max with iwconfig, but this didn't change anything. I'm running out of ideas. Any idea?

    So long I tried as Gusar said to loading the rtl8723b module with those params:
    sudo modprobe rtl8723be fwlps=0
    sudo modprobe rtl8723be ips=0
    So far by now, the connection hasn't dropped (one hour since I made the change)
    But is quite strange that when I do
    [astinx@compu ~]$ more /sys/module/rtl8723be/parameters/ips
    Y
    I mean, the parameters changed or not? I also tried with setting with N instead of 0.
    EDIT:
    The drop downs come back shortly after. I find quite strange that I cannot manage the power from iwconfig
    [astinx@compu ~]$ sudo iwconfig wlp9s0 power off
    [sudo] password for astinx:
    Error for wireless request "Set Power Management" (8B2C) :

  • Connection drops with arch64 and atheros wireless

    Hi, I've just installed arch64 on my desktop. I have a dlink dwa-556 wireless adapter, with atheros chipset. The card is seen correctly and has been configured. I started a kdemod install with pacman, went on for about an hour, and then it hung, the wireless connection dropped... I tried to start it up again, but only a reboot could help... now I started pacman again and after some minutes bang! connection dropped again...
    this is what iwconfig says
    wlan0 IEEE 802.11bgn ESSID:CUT
    Mode:Managed Frequency:2.432 GHz Access Point: Not Associated
    Tx-Power27dBm
    [cut]
    Link Quality:0 Signal level:0 Noise level:0
    [rest is all 0]
    iwlist says my router has a quality of 30-40/100 and a signal level of around -76dBm
    any help?
    edit: typo on title

    I think I may be experiencing something similar. I'm also running Arch64 and have the exact same adapter (DWA-556) and every once in a while my wireless connection drops. It only happens once every few days or so, but whenever it happens on my system it seems to cause anything Xorg-related (mouse, keyboard, video) to respond slowly. If I move the mouse around it doesn't move smoothly - it kind of jerks and jumps around.
    Whenever the connection drops like this, I see the something like the following in /var/log/messages.log:
    Feb 16 17:07:26 blacktower dhcpcd[19326]: ath0: carrier lost
    The first couple of times this happened to me, I had to reboot to get the connection going again. I did find another way to get the connection working, though. What I did was unload the modules related to the wireless adapter, reload them, and then reconnect to the network. I wrote a quick shell script to do this for me, which looks like this:
    #!/bin/sh
    sudo rmmod ath_pci ath_rate_sample ath_hal
    sudo modprobe ath_pci
    sudo modprobe ath_hal
    sudo netcfg -d home
    sudo netcfg home
    I'm using the madwifi driver right now and as you can see, I use netcfg to connect to my wireless network here. I've tried the ath5k driver but I seem to have the same issue with that. I haven't really found a solution to this yet, but the workaround of removing the modules, reloading them, and then reconnecting has worked well enough so far. If I dig up anything else helpful on this, I'll be glad to post it here.

    our customer has a problem with correct closing TCP connections on the ACE. TCP session (HTTP protocol) is closed _correctly_ (we can see it in the sniffer output), but 'sh conn' on the ACE shows it as 'established' (session is already closed). TCP timeout is set to default (60min).
    Any new connection from the same src port (because many connection to the service) is closed after TCP session is established.
    When I try generate 200 concurrent sessions TCP sessions in my lab, this are on the ACE closed correctly. Customer's traffic is around 20-30.000 concurrent session, but I can't generate so much traffic.
    SW version on the ACE: 3.0(0)A1(3b)
    thx
    martin

    Thanks Gilles!
    The problem occurs only with traffic from WAP nodes (too many short HTTP requests).
    We try it upgrade to A1(5b), but I'm not sure, if this is our problem...
    Bug description:
    Symptom:
    With L7 LB configuration, Some times connections do not close.
    Conditions:
    SYN sent to Real server may result in ACK coming from server. ACE TCP module was not handling this ACK correctly.
    ...but our traffic is only L4 LB and we have a problem with connection state on the ACE from both sides (client and server). on the client and server side is connection closed properly, but on the ACE module ('sh conn') we can see it in 'established' state. It's closed after TCP timeout and that is not correct.

  • ACE Sticky Connections, Show Conn Output and Show serverfarm

    Hi Community,
    I'm deploying a Cisco ACE module and I have some questions about sticky connections and about the output of the show conn command and show serverfarm command.
    I have the follwoing configuration:
    rserver host srv_1  ip address 10.4.11.14  inservicerserver host srv_2  ip address 10.4.11.18  inserviceserverfarm host farm_144  rserver srv_1 144    weight 1    inservice  rserver srv_2 144    weight 3    inservice
    sticky ip-netmask 255.255.255.255 address source st_host144
      timeout 10080
      serverfarm farm_144
    class-map match-all vip_144
      2 match virtual-address 10.4.11.208 tcp eq 143
    policy-map type loadbalance first-match lb_144
      class class-default
    policy-map multi-match policy_vip_webcache
      class vip_webcache_144
        loadbalance vip inservice
        loadbalance policy lb_144
        loadbalance vip icmp-reply active
        nat dynamic 411 vlan 411
    We can assume that service policy was applied at the interface vlan. So, let's go to the questions:
    1- If sticky is enabled the output command "show conn" should show just one entry by ip address?
    The real output is:
    DC01-ACE-01-PRIMARY-SW1/context_servidores# show conn | inc :143333046     1  in  TCP   411  10.2.158.87:3616      10.4.11.208:143       ESTAB 286390     3  in  TCP   411  10.2.158.87:3562      10.4.11.208:143       ESTAB310233     1  in  TCP   411  10.1.5.87:3424        10.4.11.208:143       ESTAB
    Look that the ip address 10.2.158.87 is shown 2 times. In same times, the same ip address is shown 4 times to the same VIP and the same port. Is it a normal behavior?
    2- According to the configuration, the srv_2 has weight 3 and srv_1 has weigth 1, but the output of show serverfarm show somethin strange:
    DC01-ACE-01-PRIMARY-SW1/context_servidores# show serverfarm farm_144 serverfarm     : farm_144, type: HOST total rservers : 2 state          : ACTIVE DWS state      : DISABLED ---------------------------------                                                ----------connections-----------       real                  weight state        current    total      failures    ---+---------------------+------+------------+----------+----------+---------   rserver: srv_1       10.4.11.14:144        1   OPERATIONAL     11         386        0   rserver: srv_2       10.4.11.18:144        3   OPERATIONAL     35         66         0
    We can see that the weight is working good, but the total of connections is higher at srv_1 than srv_2. Why?
    Somebody can help me to understand better this problem of if its a normal behavior?
    Thanks in advance!!

    Hi Gaurav,
    About question 1, I got some informations too. It's perfectly normal the client open 2 or more connections at the same time. The client's application is the responsable. We removed the ACE and put the client directly to the server and the result of the total connections opened was the same.
    About question 2, I made some "clears" on the serverfarm, the sticky database and after that, the numbers were more real.
    DC01-ACE-02-SECONDARY-SW1/context_servidores# sh serverfarm farm_webcache_144
    serverfarm     : farm_webcache_144, type: HOST
    total rservers : 2
    state          : ACTIVE
    DWS state      : DISABLED
                                                    ----------connections-----------
           real                  weight state        current    total      failures
       ---+---------------------+------+------------+----------+----------+---------
       rserver: srv_webcache_1
           10.4.11.14:144        1   OPERATIONAL     1025       15499      4436
       rserver: srv_webcache_2
           10.4.11.18:144        2   OPERATIONAL     1794       33471      471

    Anyway thank you very much for your feedback.

  • Connection drops on a daily basis / Varying (low) ...

    People probably know the drill by now, everything is fine then suddenly they go through a period where they receive barely a 10th of their paid connection speed, with their connection dropping completely at least once per day.
    This all started happening when BT somehow increased our connection speed from 8Mbps to 21Mbps and also increased our upload from about 250kbps to 1Mbps which happened a couple months ago now. This was great! Everything was working fine, no drops in the connection or speed and it seemed like they had given us a nice boost for free.
    That is, until things started going wrong about a month later when our connection would frequently drop, the connection speed would often fall to below 1Mbps and this is still happening.
    With regards to solving this problem myself, I don't see how anything could be interfering with the setup I currently have, as nothing has changed within the house itself. Before I ring up an Indian/ Chinese/ Scottish/ Martian call center, I'd like to try and get some feedback from the users on this forum.
    I'm going to buy some new ADSL filters just to see if the ones I'm currently using are packing up (they're cheap so that is no problem if nothing changes).
    I have run quite a few speedtests using the recommended btspeedtester and have had varying results, all of which barely, if at all, meeting the acceptable range of speed for my line. Here is my most recent test:
     Download speedachieved during the test was - 4563 Kbps
     For your connection, the acceptable range of speeds is 4000-21000 Kbps.
     IP Profile for your line is - 11000 Kbps
