WCCP Mask change in 4.2.3c

Hi All,
We upgraded the WAE from 4.1.5f to 4.2.3c. We did not disable WCCP in the IOS router before and after the upgarde so the Mask assignment remained the same ( 0x1741).
We have the situtaion where , we need to add a new WAE with code with code 4.2.3c to existing setup which has existing WAE.
How do we change the WCCP Mask assignment to 0xF00 in the IOS router so that we can make both WAE to work in load sharing basis.
Thanks,
-Dhana

Dhana,
Before adding the 4.2.3 WAE to this farm which should have the default mask of 0xF00 configured already, you will need to go to the CLI of the other two WAEs that were upgraded from 4.1.5 and execute the config command "wccp mask is src-ip-mask 0xf00 dst-ip-mask 0x0"
Then all three WAEs will have the same mask value, and it will be safe to bring the 3rd WAE into this farm.
No configuration changes are required on the router.

LUN Mask changes without reboot?

Are there any controller firmware enhancements in process to allow LUN masking changes without a controller reboot? We have several XRAIDs in our SAN with masking enabled. With the current limitation we must schedule several servers to be down before making the changes. That's really a pain...
Other OS

Apple won't typically comment on any future products or enhancements.
However, your request is a common one. I suggest you contact Apple (via web site or via your sales rep, if you have one) and suggest the enhancement and let them know your pain.

C7-00 wifi subnet mask changes automatically

Hi,
I am facing a problem in my c7 that it wifi subnet mask is changing automatically even if i set it manually.
thanks
bikramjeet singh ballagan

no open apps ...
I did a bit of testing today and discovered, that the connection doesn't close, only when I exit OVI Store (this happens with WLAN and also with 3G/UMTS connection).
When I exit any other app (e.g. Browser, Opera, ...) the connection closes automatically after I have closed down the app.
So this must have something to do with the OVI Store, probably with the new version as I cannot remember to have experienced this until some days ago.

WAAS: WCCP Mask or Hash on Routers?

I'm starting thinking about using mask assign on an ISR router running 12:4(24)T with GRE/GRE. Has anyone done this before and can you use mask assign with GRE/GRE? We need to use it with GRE/GRE because our egress method has to be WCCP return. My thought was mask assign will be much better at load balancing across multiple WAEs in a cluster than hash because you can specify a long mask assignment. Right now, see more load on WAE than the other and are sometimes getting TFO overload.

The page you linked contains recommendations (in bold) for each platform. On the ISR G2 specifically, you should be able to use any combination of GRE/L2 and MASK/HASH assignment. Some other platforms require specific disribution and redirection methods to maintain the hardware acceleration of WCCP traffic. However, the ISR G2 does not have this requirement.
WCCP GRE and HASH distribution on ISR G2 is typically recommended to make deployment easier. With GRE, content devices can be an L3 hop away (if needed), and it reduces the chance of customers accidentally creating a WCCP redirect loop.
L2 distribution and HASH redirection method should typically require the least CPU and memory load on the ISR. These should perform the best in most cases.
The MASK distribution method gives better controls on how load is divided between multiple content devices, typically at the cost of more CPU and memory utilization. If you have only one or two content devices in your cluster, typically HASH will meet the need for slightly less CPU. As Zach said, most times MASK is used on the Datacenter side to give the ability to 'tweak' how the load is distributed across multiple devices.
Thanks,

WCCP mask and weight?

Hello
We're setting up an scenario with datacenter with three WAEs using WCCP to distribute the load.
The core switches are catalyst 6500 so we're using redirect in. L2 redirection and mask to optimize forwarding of redirected packet.
the problem is that the three WAEs are not equal. Two are 612-2GB and the other is a 7341, so we want to use the weight parameter of the wccp tcp-promiscuous command, but I'm not sure if this parameter works also with the mask mode or only with hash mode. And couldn' t find a definitive answer in the documentation.
It's possible?
Regards, Fernando

Fernando,
Typically we don't see/ nor recommend using such different devices, especially in the data center. The 7341 can handle up to 12000 concurrent optimized connections, and the 612-2GB can only handle up 4800 concurrent optimized connections.   So, in the event of a 7341 failure you will lose more than half of the connection capacity you data center can handle.
However, you can use the weight keyword with mask assignment. I just confirmed in my lab two WAEs connected to a 6500 with the following config:
WAE 14.110.3.19
wccp router-list 1 14.110.3.17
wccp tcp-promiscuous mask src-ip-mask 0xf dst-ip-mask 0x0

wccp tcp-promiscuous mask src-ip-mask 0xf dst-ip-mask 0x0

Wlc 5508 webauth subnet mask change issue

Recenly l changed the network subnet for a particular wlc interface and scope and also an upstream router and for some reason it would only allow me to use a /24 Host mask as my plan was to go to a /22 mask to allow for over 1000 hosts within this scope.
The Upstream Router which is a ( RV042 ) had the following original config :
     192.168.1.1
     255.255.255.0
I have noticed this device will not let me change the mask from a /24 to a /22 as you can only change from a pre-defined list of masks and you cannot manually add any either..
New Config
     10.10.0.10
     255.255.255.0
WLC 5508 Controller Interface
     Original Config
      192.168.1.25
     255.255.255.0
     192.168.1.1
     New Config
     10.10.0.25
     255.255.252.0
     Scope
     Range : 10.10.1.10 - 10.10.3.254
     Mask : 255.255.252.0
     Network : 10.0.0.0
     Router : 10.10.0.10
When l reconfigure to this addressing the wireless clients connect and get the new dhcp scope details but following this the webauth screen doesn't appear not allowing them to connect meaning there is no routing of traffic / internet access.
If l modify the above interface and scope masks back to a /24 - 255.255.255.0 the the wireless clients connect and webauth appears to prompt them to accept the terms and conditions and connect thus giving them internet access.
It looks like an issue with the mask ? The main reason l am trying to change the subnet addressing is because the standard /24 mask is not providing enough dhcp addresses and we have had times were the scope has been exhausted due to the public connecting and disconnecting as the lease perod of 2 hours holds onto the address before expiring meaning there is not enough available addresses for people to connect.
I would of thought that the upstream router ( RV042 ) even though it is only a /24 mask would still route the traffic coming from a WLC Controller interface with a /22 mask ?
Hopefully someone can suggest a solution ?
Thanks Simon

Hey Scott just getting back to this issue..   If for instance l can modify the wlc interface and Scope to have a /22 mask ( 1022 Hosts ) and my upstream Router ( Cisco RV042 ) can only provide a /24 or higher mask then does that mean l am still limited to a range of 254 hosts ( /24 Mask ) ? Would this mean l need to look into replacing my upstream Cisco RV042 VPN Router ?

Presentationser won't start after subnet-mask change

After changing the subnet mask (in order to be able to connect to the server remotely), the 'Oracle BI Presentation Server' service (sawsvc) will not start anymore.
Eventlog shows: The Oracle BI Presentation Server service terminated with service-specific error 4294967295 (0xFFFFFFFF).
Can anyone help me out, what I have to alter, in order to make things work again?
After updating the host file I am able to connect to the database, so sqlplus and OBIEE administrator work. It is analytics that will not run anymore because of the service that will not start.
thank you for any help you can give,
Jeroen

Thanks for letting the community know.
The behavior described is usually related to issues with the startup files used to boot Windows. However, this could be one of the outliers.
HP units are usually pretty good about detecting incompatible memory and won't get as far as it is getting.
In the mean time, it certainly wouldn't hurt to try the steps listed while waiting for them to arrive.

Coding Mask Change

Hi All
I m trying to change the digits on my coding mask for the Project ID, but I keep getting the error - CJ611.
I went into the OSS note 453280 but havent been able to find a suitable solution.
Any ideas?
Thanks much
RS

The note on Wiki states that you can only:
1) Change a numeric section to an alpahmumeric section of the same length
2) Extend the coding mask with an alphanumeric section
In the case provided by you, you are trying change the length of the coding mask (there are other voilations as well). You cannot change the coding mask as proposed by you through standard SAP practices. However, a workaround exists (as stated in the note):
1) Run the report ZZADJUSTPOSID of note 453280 to adjust the project and WBS element numbers as much as possible in background. Some dialogue may, however, nevertheless occur.
2) Run the report ZVERSION_UPDATE of note 616732 to adapt the project and WBS element numbers in the project versions involved accordingly.
Please go through these steps, SAP notes and the wiki document (the part about testing this solution first).

Ammar

Why do masks change position when I move them to other layers?

I created both a simple shape mask and also a complex bezier shape mask. When I move these masks to other layers they change their position. Is there a way to change this behavior?

They are positioned in relation to the original object, and the Group that object is in. Copying them to another object may sometimes require you reposition them.

Project coding mask change

Hi Experts
My coding mask is :                AA/XXXXXXXX-XXX-XX-X-X-X
Now i wish to change to:       AA//XXXX-XXX-XX-XX-XX-XX
But the system does not allowed specying the method of changes.
I have deleted in Config client and created a new.
My requirement is to take this to testing cleint
Is there way to change?

hi guys,
I would like to change my project coding mask already existing, and used (so i have wbs element created already)
using transaction OPSJ
i wanted to add 5 character at the end of the existing codification
Before : AA.XXXXXX.XXX.XXXX
After :   AA.XXXXXX.XXX.XXXX.XXXXX
of course, i have the SAP scary message.
i did look for OSS note 520944 - and it looks like i can do it (see the note extract)
If you want to change an existing editing mask in Customizing, the
following rules apply:
o You can only add one new alphanumeric section to the editing mask.
o You can change a numeric section into an alphanumeric section of
the same length (see Note 521625).
o You can change the special characters of the editing mask. If you
use the solution of Note 441749, you have to update the affected
objects on the database (see Note 441749)
as, honnestly the note are note really clear on this subject,
Does somebody ever done this change in production system ? your feedback ?

WCCP redirect on 4507 to ironport

I would recommend doing the following. Also feel free to call into the ironport support line. It is listed at the bottom of the page.
Change the wccp service to service-number 90
Try to redirect inbound traffic not outbound traffic.
Set Load-balancing to mask
Set forward method to L2
Set return method to L2
ip wccp 90 group-list IRONPORT-GROUPLIST <- Set the wccp service-number
ip wccp source-interface GigabitEthernet2/24
Interface Vlan160
ip address 10.10.16.1 255.255.254.0
ip wccp 90 redirect out <- Set the WCCP Service-number try to redirect inbound traffic
ip access-list IRONPORT-GROUPLIST
permit ip any host 10.11.1.10 (10.11.1.10 is the ironport proxy IP address)
Below is an example of how you should setup your ironport for a customer service number. Place the port numbers that you want to redirect.

WCCP assignment method mismatch

Hi all,
I am using a Cisco 3825 running 12.4(25G) code. I just upgraded my WAE (oe674) to 5.1.1c.
The WAE and router wouldnt peer due to assignment method mismatch when i do a show wccp router.
Router Information for Service Id: 61
        Routers Seeing this Wide Area Engine(0)
                -NONE-
        Routers not Seeing this Wide Area Engine
        10.204.28.1     - Assignment Method Mismatch
        Routers Notified of from other WAE's
                -NONE-
Router Information for Service Id: 62
        Routers Seeing this Wide Area Engine(0)
                -NONE-
        Routers not Seeing this Wide Area Engine
        10.204.28.1     - Assignment Method Mismatch
        Routers Notified of from other WAE's
                -NONE-
The WAE is configured as follows:
wccp router-list 1 10.204.28.1
wccp tcp-promiscuous service-pair 61 62
router-list-num 1
assignment-method mask
password ****
redirect-method gre
egress-method wccp-gre
enable
exit
wccp flow-redirect enable
When i changed the assignment method to hash, everything worked. I believe Cisco 3825 should support Mask.
Any advice?

Hi Leonardo,
Did you try disabling wccp on router as well as WAE and re-enable it on router and then WAE and see if that makes a difference? If you have already done that and since as per documentation MASK assignment is supported in version you are running on router and it was working prior to upgrade, i would suggest capturing WCCP communication i.e HIA and ISU and opening a TAC case for further investigation. Did you follow the procedure as suggested in release notes during upgrade?
WCCP Interoperability
Central Managers running Version 5.1.1x can manage WAEs running software Versions 4.2.1 and later. However, we recommend that all WAEs in a given WCCP service group be running the same version.
Note All WAEs in a WCCP service group must have the same mask.
To upgrade the WAEs in your WCCP service group, follow these steps:
Step 1 You must disable WCCP redirection on the Cisco IOS router first. To remove the global WCCP configuration, use the following no ip wccp global configuration commands:
Router(config)# no ip wccp 61
Router(config)# no ip wccp 62
Step 2 Perform the WAAS software upgrade on all WAEs using the WAAS Central Manager GUI.
Step 3 Verify that all WAEs have been upgraded in the Devices pane of the WAAS Central Manager GUI. Choose Devices to view the software version of each WAE.
Step 4 If mask assignment is used for WCCP, ensure that all WAEs in the service group are using the same WCCP mask value.
Step 5 Reenable WCCP redirection on the Cisco IOS routers. To enable WCCP redirection, use the ip wccp global configuration commands:
Router(config)# ip wccp 61
Router(config)# ip wccp 62
Release notes for your reference.

Mask Calculation's and Performance

We will have two 7341 WAE's in our Data Center. We have several hundred servers that branch sites pull (and sometimes push "SharePoint") centralized resources from. To even out the load, we are moving Service Group 62 to the WAN interface and 61 to the LAN interface on the Data Center Router. I would also like to create a "Mask" that effectivly doubles my DRE capacity by alternating WAE's based on the destinations last octet. Using a mask calculation that alternates 7341 boxes based on the last octet of the IP address seems to be the most effective method. Are their any performance hits or faults with this method of load distribution?
Using Cisco's "WCCP-Mask-calc-v103", I came up with 0x01 as the value to alternate based on the host address.
Is that the proper mask to alternate hosts based on their last octet?
Are their any inherited issues with using this mechanism?
Has anthing changed with 4.4.1 / 4.4.3 that would render this inoperable or unsupported?
Will this eat up resources on the router?
7341#1
10.0.0.0
10.0.0.2
10.0.0.4
10.0.0.6
7341#2
10.0.0.1
10.0.0.3
10.0.0.5
10.0.0.7

Hi Ryan,
This mechanism is fine and hold true for 4.4.1/4.4.3 as well.
However it is purely based on the requirement whether you want to load balance based on the last octet or the last but one octet. If you have multiple sites of Class C subnets you may probably want that all the users from one site should always go to the same WAE in datacentre so that it provides higher cache hit ratios quickly. If you have less number of sites and you may want to do the load balancing on a per user basis in which case both the WAEs DRE will be populated with the same kind of cache.
Hence it depends on the number of sites / users etc based on which you can decide on a mask value for load balancing.
Please refer to the below URL for the recommended assignment method on different platforms.

Hope this clarifies.

How to do Data Masking in SAP?

Hello All,
How to do Data masking in SAP, My Client has a production data, so we have to create a development environment with this production data but the data should be masked/changed with some dummy data, and it should work as test data for developments in dev environment.
Please tell me the Process? Approach? and how to do it in SAP?

Hi,
this kind of tools already exist in SAP, if you client have some money to spend : TDMS

How to Pan and Scan and keep a mask stationary?

I am trying to pan and scan a clip that has mask. But I do not want the mask to follow the pan and scan. Can this be done?
I am using CS5 on Win7

Thanks. So I just need to create a solid, punch my hole in it using the mask, disable the solid visibility, then use it as a track matt for my layer that I was trying to mask. This should work perfectly.
But why does a mask change positions and size when I change the layer's position and scale in the first place? If you change the track opacity, the mask opacity does not change. Does the mask also follow a parented layer's scale, etc? I have probably taken advantage of this "feature" in the past w/o thinking about it. But now it sounds counter-intuitive to me. It would be nice if there was an option for the mask size, position etc. to follow the layer's properties or not.
