Local Director Clear Stats
I've got a LD416 running 3.1.4. I need to clear the statistics on it to help examine a problem. Is there any way to do this in 3.1.4? I've been going through the docs and maybe I'm blind but it doesn't seem to an option???
Thanks

unfortunately there is no way - except the reload.

Local Director network placement
I need to move the Local Director in my network to a new location. Currently, it sits between my Cat 4003 (yes, I know that is really old) and the firewall - ASA. This placement has workd great up until now. I need to have a trunk link between the ASA and the 4003. What I have read states that I should us a multiple switch setup. What I am wondering is if I can use a multiple VLAN set up on the same switch. See attachment pictures for clarification. Would that work? If not, how can I set up LD to still work in my network, but have a trunk link up to the firewall? Thanks!
This usually happens when the backend service is unavailable, and the LD tries to reassign a connection to it (to see if it has recovered).
* Can you post the output from 'show real'?
* What version of LD software are you running.

If a failover occurs from the primary to secondary local director, what is the state of the config on the newly active standby device. During normal operation, I believe the standby device only stores the config in memory. Does this mean that if it is rebooted after it has taken over from the failed primary, the config is lost? What is the recommendation regarding safeguarding the config on the standby active device whilst the primary is being attended to?
As you mentioned, when the standby takes over the configuration is stored in the memory and the previous configuration on the standby is erased. There is a bug with the local director not replicating its configuration to the standby unit correctly.
That's probably the reason why the standby might have rebooted. I have no idea on how to safeguard the configuration. Any suggestions out there?? -
Using the Cisco Local Director
Hello All-
We are attempting to set up a server farm that is load balanced with the Cisco Local Director and are experiencing difficulties with some clients whose networks have multiple proxy servers. We have used both the generic sticky command as well as the cookie-insert sticky without total success. Our next option looks like we should put our own proxy server in front of the LD and use SSL. Has anyone experienced these problems and come up with a solution. Unfortunately we don't have weblogic clustering licenses so our state is lost whe a client gets redirected to a new server. Thanks for your time!

415.887.9106In directed mode, the client browsers are configured to point to a proxy to a virtual IP address on the Local Director. I know the Local Director does not support a real server that does not have a virtual address defined so it can't transparently forward like the CSS.

Migrating Local Director to CSM - commands "name" "oos"
On a CSM v4.2(3) on a 6509: I'm trying to make the real servers have names (like on the local director) instead of IP addresses:
VOC-SW15#conf t
Enter configuration commands, one per line. End with CNTL/Z.
VOC-SW15(config)#mod csm 4
VOC-SW15(config-module-csm)#serverfarm TEST1
VOC-SW15(config-slb-sfarm)#real ?
A.B.C.D real server IP address
name use a named real server
VOC-SW15(config-slb-sfarm)#real name webtest
% Config not found for module real WEBTEST
VOC-SW15(config-slb-sfarm)#real name ?
WORD real server name
VOC-SW15(config-slb-sfarm)#real name webtest
% Config not found for module real WEBTEST
VOC-SW15(config-slb-sfarm)#
VOC-SW15(config-slb-sfarm)#real webtest
VOC-SW15(config-slb-module-real)#address 10.1.250.37
This is what I end up with (I want the real server under server farm test1:
real WEBTEST
address 10.1.250.37
serverfarm TEST1
nat server
no nat client
real 10.1.250.38
inservice
Also, if anyone has an easy way to take a box out of service (like on the local director) please let me know. On CSM we're having to do this:
VOC-SW15#conf t
VOC-SW15(config)#mod csm 4
VOC-SW15(config-module-csm)#serverfarm relays
VOC-SW15(config-slb-sfarm)#real 10.1.11.23
VOC-SW15(config-slb-real)#no inservice
on ld it was just: oos real relay-01
Thank you for all the posts. They have been tremendous help in getting the CSM in production.
ps (Gilles, My Christmas wish is that you're working on a CSS/CSM Book for Cisco Press. One is definately needed)
Thank you, SheilaWe figured out the name configuration.
real MLXWEBTEST
address 10.1.250.36
inservice
serverfarm TEST1
nat server
no nat client
real 10.1.250.38
inservice
real name MLXWEBTEST
no inservice
real server farm weight state conns/hits
10.1.250.38 TEST1 8 OPERATIONAL 0
MLXWEBTEST TEST1 8 OUTOFSERVICE 0
Is this the best configuration? We have to migrate
250+ servers over to the CSM. Thanks, sheila -
Server load balancing on Local Director implementing HTTP redirection
Hi, got an interesting problem when implementing the HTTP redirection method of session persistance or stickiness when balancing a couple of web servers on a Local Director 416. The session persistance works fine but it looks like one of the two servers is getting all the traffic rather than balancing accross the two. The servers are equally spec'd and when it comes to the predictor setting for the virtual, I'm just using the defaults i.e. leastconns/roundrobin. Is there a better predictor setting to use?? Any input would be appreciated.

Adam LacobaThe loaded argument has worked well. Take note that this requires a value to be set with the weight command. It gives a specific amount of traffic to one, and then moves to the other.

Local Director Load Balancing question
Using IOS 3.2.2
I have a local director 416 with 2 real servers. I would like to send all traffic to 1 server and if it fails to switch over to the secondary server. The way I see to do it is to use weighted load balancing and set the weight of the 2nd server to zero. But if the primary server fails what will happen since the secondary server has a weight of zero.
JasonNot being a Cisco employee, I guess I can't define what "proper" is, but with the backup command, you don't need to play with the weights at all.
You just bind the primary real server to the virtual, then assign a backup to the primary. The backup server does not get directly bound to the virtual, so the only way it's going to get any traffic is if the primary server is down. -
Local Director SNMP for CPU and Memory

SNMP problem in Local Director 416 V4.2.3
I am unable to get SNMP response from local director :
herafter the snmp configuration .
snmp-server host 62.184.xx.yy
snmp-server enable traps
snmp-server community xxxxxxxxx
snmp-server contact Philippe
snmp-server location B2
What else should be in configuration to have the local director respond to
SNMP request from snmp-server host 62.184.xx.yy ?
Thanks for your help.This is not expected behavior with the LD.
I did see one bug (CSCdw87752) regarding the LD duplicating multicast packets in 4.2.3. The scenario was slightly different. In the bug, the LD was duplicating multicast packets from a Checkpoint Firewall. That bug is fixed in version 4.2.4. I think it is likely that this fix will also fix your issue.
Let me know if that works or not...

Port based LB and Local Director
My customer would like to know whether the Local Director supports Load Balancing using the source port information. If this is possible any document on the configuration wouldbe highly appreciated.
Regards,
Maheshhttp://www.cisco.com/en/US/products/sw/iworksw/ps2769/products_maintenance_guide_chapter09186a008007d9fa.html#xtocid225795
as per this document i think the loadbalancing based on source port information cannot be done.
''The MNLB Services Manager makes the load-balancing decisions based on application availability, server capacity, and load distribution algorithms such as round robin or least connections, or the Dynamic Feedback Protocol (DFP).'' -
Local Director & HTTP Redirection
Hi, just wondering if anyone has successfully implemented HTTP
redirection on Cisco Local Director 416 running ver 4.1.2 Basically I'm
after any pitfalls to look out for. Current implementation utilizes
generic session stickiness however this has problems for clients
trying to access our load balanced servers if they come from behind
multiple proxies via their ISP.
Servers are Private IP addressed (Firewall in front of LD performing NAT static
txlation)
On another point, how does the Cisco CS11000 (Arrowpoint) perform
session persistance/stickiness or what "better" ways does the
Arrowpoint acheive this as compared to Local Director?
Any helpful input would be much appreciated.

On Cisco site Local Director 400 series has been classified as End of Sales. Does anybody know what product replaces them?
Also I would like to know if IOS Server Load Balancing feature does the same job of Local Director as far load balancing between Web server s is concerned.
Thanks for any input.The Local Director has a few potential replacements.
IOS SLB can perform the same function and if you have a 6500 already, it may be a good choice.
Also, the Content Swtiching Module (CSM) is more robust and has additional fuinctionality such as one-armed load balancing and firewall load balancing, among others...
The Content Services Switch (CSS) is a separate appliance that also has additional functions from the LD. It is comparable to the CSM in features.
Both the CSM and CSS have optional SSL modules to integrate SSL temination allowing the Load Balancer to do layer 5 inspection of "encrypted" traffic.
Hope this helps!

Does the Cisco Cache Engine Work with the Cisco Local Director ?
I need to know if it is possible and how to use cisco local director to redirect traffic to the cache engine in reverse proxy configuration and transparent proxy configuration.
In directed mode, the client browsers are configured to point to a proxy to a virtual IP address on the Local Director. I know the Local Director does not support a real server that does not have a virtual address defined so it can't transparently forward like the CSS.
