Configuring VLANs

This chapter describes how to configure VLANs on the CSM and contains these sections:

• Configuring Client-Side VLANs, page 4-2

• Configuring Server-Side VLANs, page 4-3

When you install the CSM in a Catalyst 6500 series switch, you need to configure client-side and

server-side VLANs. (See Figure 4-1.)

Client-side or a server-side VLAN terminology logically distinguishes the VLANs facing the client-side

and the VLANs connecting to the servers or destination devices. However, CSM client and server

VLANs function very similarly. For example, new connections can be received on a server VLAN, and

then be load-balanced out to a client VLAN.

The differences between client-side and server-side VLANs are as follows:

• When configuring bridge mode, you cannot bridge two server VLANs or two client VLANs. You

can only bridge a client and a server VLAN.

• Denial of service (DoS) protection features are more aggressive on the client side VLANs,

especially when rate limiting control traffic is sent to the central processing unit.

Note You must configure VLANs on the Catalyst 6500 series switch before you configure VLANs for the

CSM. VLAN IDs must be the same for the switch and the module.
