| Configuring the WSM using Device Manager |
|
Although VMA is enabled by default on the WSM, if you have previously configured a proxy IP address for a port, VMA may be disabled initially following upgrade to the current WebOS.
Prior to enabling VMA, if any port is configured with a proxy IP address, then all ports must be. The proxy IP address identifies the processor to process responses. With VMA, a global session table replaces the concept of a per-port session table.
With proxy enabled on a WSM port with a proxy IP address, frames ingressing the port can be processed using a proxy IP address by any WSM port. The client source address is substituted with the proxy IP address of the port processing the request.
If proxy is not enabled for a WSM port with a proxy IP address, frames ingressing the port are processed by other ports configured with a proxy IP address; but the client source address will not be replaced with a proxy IP address before it is forwarded to a server.
