CITRIX Repeater with WCCP

brendon — Wed, 09 Sep 2009 04:50:12 +0000

When deploying a CITRIX Repeater (formally known as WANScaler) using WCCP with a cisco router we found that the configuration on the KB isn’t quite right. Read on for the configuration.

The Repeater configuration we used are:

The CISCO Router Configuration we used is:

ip wccp 51 redirect-list wccp_redirect
ip wccp version 2
!
interface FastEthernet0/0
 Description ‘Internal LAN Interface’
 ip address 10.228.3.101 255.255.255.0
 ip wccp 51 redirect in
!
interface FastEthernet0/1
 Description ‘WAN Link’
 ip wccp 51 redirect in
!
ip access-list extended wccp_redirect
 permit host  any
 permit any host 
 permit host  any
 permit any host

You can use the command ‘show ip wccp 51 detail’ and ‘show ip wccp’ to check the tunnel before adding the ‘ip wccp 51 redirect in’ command on the interfaces. And believe me, you don’t want to leave a ‘debug ip wccp packet’ active on a production device that routes 30Mbit of wan traffic. Just in case the redirect list is wrong and the router tries to display all packets flowing through it….

Repeater v5 ICA Acceleration Debug

While there is no direct link to it, accessing a Repeater management console with the address http:///ica_debug.php will let you monitor individual ICA sessions for compression, connection stats, etc. Great tool, its a pitty Citrix had to hide it!

Interesting point to note, when using client session printing on a connection between an ICA v11.0 client and XenServer 5.0 FR3 AND you happen to be running a pair of CITRIX Repeaters on version 5.0.32 AND you have any printer bandwidth limiting defined anywhere in the ICA farm…. Your printing goes REALLY REALLY slow.

Check the preferences and farm settings to make sure its not enabled, then use the inbuilt QoS CoS on the Repeaters to control performance.

CITRIX Branch Repeater – Advanced Options

CITRIX have a neat new product available for WAN Optimisation that works hand-in-hand with their WANScaler range of products. Designed for those sites that have too many staff for *just* a WAN link and not enough to warrant an onsite Server.

The Branch Repeater is a little 1RU server designed for a standard COMMS rack, which apart from applying CoS policies and compressing traffic flowing through other WANScalers runs Windows Server 2003 R2. So you can configure it to host DHCP, DNS, WINS, DC, GC, Printer Shares, FRS, etc.

A little known fact is that pressing Ctrl + Alt + W will bring up additional debugging options on the BranchRepeater system tray icon.

Personally I don’t know why they hid it, just means people like me who have to install and support these lives are that little bit harder..
