Trunk support on Local Director
Anyone know if the trunk (802.1q or ISL) is supported on LD 417G? I have found the following description on the release note but I can't find any info about configuring it.
"One two-port 1000BASE-SX Gigabit Ethernet interface card with SC connectors that support load balancing, link aggregation, and trunking (LocalDirector 417G only)"
Thanks a lot for this info.
I'm not happy but better that not know anything...
Any idea on when will be witten? Only to know when we could show something official to the customer.

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.

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).'' -
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.

Local Director Remote Management
Is there any way to use SNMP to manage the Local Director. I have the SNMP community but I can't seem to change the server status from out of service to in service using snmpset (from UCD-SNMP). Am I doing this in vain. Are there any ways to do remote management of the LD or can it easily be scripted. Thanks.
you cannot SET values for the Local Director through SNMP. Just GET them.
There used to be a GUI for the LD, that works up to version 3.x. It no longer works in version 4.x. The name for it is CVS and it can take servers out of service. It does it by telnetting to the LD and issueing commands.
Also, the LD support Dynamic Feedback Protocol (DFP) which is a protocol that allows the LD to talk to an agent application (installed on the server) and can dynamically adjust the server weight according to load.
Hope that helps,

Our web folks are testing an application that currently does not support server clustering. They want to have all web traffic be directed to one server(server1) and have a second (server2) identical server as a backup.
I was wondering if can bind the real server (server1) to the virtual server and have the second real server (server2) backup the first real server using the backup command? Is there any potential pitfalls that I may need to take into account by doing it this way?
Also they wanted to know if the Local Director would work in the previous scenario if the two servers are physically connected to the same switch but reside in different VLANs?
Any input would be greatly appreciated.
ThanksThis is exactly how you would configure it. There is only one potential pitfall that I can think of in your particular scenario. If server1 fails, server2 starts getting the connections. As soon as server1 comes back into service all the new connections will be sent to server1. This is a good thing in most situations but you need to see if the application can deal with this.
Regarding location of the backup box. When you say the two servers are connected to the same switch but reside in different VLANs do you also mean that the servers are in different subnets? If so, this is a little more complex depending on the topology but can easily be worked out. If the servers are simply located in separate VLANs on the switch but are in the same subnet then this configuration should work without issue. -
Local Director & cat6500/Sup2 with ASLB or MNLP, when ?
Does somebody to know when ASLB or MNLP for Local Director will be accesible on platform cat6500 with Sup2/PFC2/MSFC2
As I know there is no support for them on such cat6500 yet.
Actually I'm using:
LocalDirector 430 with soft version 4.2.4
WS-X6K-SUP2-2GE/WS-F6K-PFC2 with CatOS 7.4(2)
WS-F6K-MSFC2 with IOS 12.1(13)E2
and can't configure nor "redirection assist" on LD nor "casa" on router

Maciej KolodziejUnfortunately that document was posted: Fri May 18 10:24:16 PDT 2001
later Cisco has produced document:
http://www.cisco.com/en/US/products/hw/switches/ps708/products_configuration_guide_chapter09186a0080121d6a.html#wp1025726
where we can find:
Note The information and procedures in this chapter apply only to the Supervisor Engine 1 with Layer 3 switching engine (Policy Feature Card or PFC). ASLB is not supported on Supervisor Engine 2 with Layer 3 Switching Engine II (PFC2).
Thus my question in subject ;-))

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.

Local director 417 replacement? CSS 11501 software 8.20
Hi,
i would like to ask if CSS 11501 (software 8.20) is still the replacement hardware for local director 417? currently we use this local director to load balance http and https traffic using a flat network implementation meaning virtual IP is in the same netwoork as the physical server. will CSS 11501 can support this implementation?
Current Local Director setup example
web server virtual IP 10.10.10.1
real server ip 1 10.10.10.2
real server ip 2 10.10.10.3
rgds,
mc.malinaolocal director is well before my time, so I can't comment on those and their official replacement.
I'd say you're better off going straight to ACE modules or appliances.
They're the latest generation of Cisco's load balancers.
We're very happy w/ our ACE-20 modules. -
CSS and Local Director comparison
I am new to this technology and I want to know what are advantages and disadvantages of Local director over the CSS and vice versa besides the price. What functionality does one has that is not supported by the other ?
If you are looking at implementing a load balancer then I would suggest to go for the CSS. The CSS is the next generation of load balancer and will replace the Local Director. The CSS functionality and extensibility is far greater than that of the local director. Another point is that feature developement is far more aggessive on the CSS.

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!

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. -

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...

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.
