Hi!!
It is possible to configure the CSS11500 on Bridge mode. We want to remove old LD430 and we need no address changes.
Some examples??
Thanks..

first of all
CSS handles bridged packets in software, unless absolutely necessary, you should avoid configuring your CSS in bridge mode. Instead, you should configure your CSS in router mode, where packets are processed in hardware. Alternatively, the CSM handles both bridge- and router-mode traffic in hardware.

You must configure the default gateway of your servers as the IP address of the Layer 3
source is cisco press
good luck

Hi Marwan
Thanks for your help.
Where we found a reference about your comments? Any link or Cisco Document?
How big the traffic through the bridge can be? There are any limits?
We have a pair of CSS11503...

I am afraid this is not correct...
The 1st generation 11000 series CSS was limted in a one armed design because FCB's (flow
control blocks) were allocated on a per port basis on a 11000 series switch. Since you are
only using one port, you only have the resourced allocated to that port.
CSS 11500 series is not adversly impacted if you have a one armed load
balancing design because the 11500 distibutes FCBs over all ports.

Hello Syed:
Very interesting information.
In general, I can't found any reference about some danger for CSS11500 bridge mode.
I think that we will configure the CSS in that way...We will using the GbEth ports on SCM for "in line" (bridge) connection.
Thanks for your help!!

hi
about the source it is good book if u can get it
cisco press, Content Networking Fundamentals, 2006
and the information i have given from there
CSS 11503 Supports one SCM, and any two of the I/O, SAM or SSL modules. Only a single switch fabric and power supply is available in the CSS 11503. Each module has 1.6 Gbps connectivity to the switch fabric, resulting in 10 Gbps aggregate throughput
Maximum Gigabit Ethernet Ports 6 (includes 2 on the SCM)
Redundancy Features · Active-active Layer 5 Adaptive Session Redundancy
· VIP redundancy
Bandwidth Aggregate 20 Gbps
Storage Options 512-MB hard disk or 256-MB flash memory disk
Power Integrated AC or DC
Default Hardware Switch Control Module with 2 Gigabit Ethernet (GBIC) Ports
# of Available Modules 3
Maximum 2-port Gigabit Ethernet I/O Module 2
those detail all about CSS 11503
good luck

Marwan, Thanks for your help and time.
But is more difficult for us to make any change on current network configuration...

so nice try to find about it

Bridge-mode enables you to configure your VIPs on the same subnet as your real servers, whereas in router-mode your VIPs and serverfarm subnets must be different.
The CSS Load Balancer has a built-in switch fabric with multiple Ethernet ports that can be configured for multiple VLANs depending upon whether the CSS is configured for Bridging or Routing mode. If the CSS is configured in Bridging (Layer 2) mode, then all the Ethernet ports are configured in the same VLAN. The advantage of setting it in Layer 2 mode is that no network level changes are required. This means that you don't need to modify any IP addressing or change default gateway settings in your network. The CSS fits transparently into your network.
In Routing (Layer 3) mode, the CSS is configured with two VLANs. Your internal router needs to be configured to use the CSS as its default gateway. Similarly, the Internet router will have the CSS interface as the next hop to reach the corporate network. This requires you to modify some of the settings in your network. If configured in Routing mode, one VLAN connects to the internal network and the other VLAN connects to the iPrisms and the external router, which connects to the Internet.
see configuration example below:

Sachin, thanks for your help an references
We will use the Bridge Mode for this...
