Configuring A Pre-Shared Key For A Vam Client; Setting The Retry Timer And Retry Times For A Vam Client; Setting The Dumb Timer For A Vam Client - HP FlexNetwork MSR2003 Configuration Manual

Step
2. Enter VAM client view.
3. Specify an ADVPN domain
for the VAM client.

Configuring a pre-shared key for a VAM client

The pre-shared key is used to generate initial encryption and authentication keys during connection
initialization. It is also used to generate encryption and authentication keys for subsequent packets if
encryption and authentication are needed.
All VAM clients and the VAM server in an ADVPN domain must have the same pre-shared key. If they
have different pre-shared keys, the decryption and authentication will fail, and they cannot establish
any connection.
To configure a pre-shared key for a VAM client:
Step
1. Enter system view.
2. Enter VAM client view.
3. Configure a pre-shared key
for the VAM client.

Setting the retry timer and retry times for a VAM client

A VAM client starts a retry timer after sending a request to the server. If the client does not receive a
response before the retry timer expires, it resends the request. If the client fails to receive a response
after maximum attempts (retry times), the client considers the server is unreachable.
The retry-times setting does not apply to register and update requests. The client sends those
requests at the retry interval until it goes offline.
To set the retry timer and retry times for a VAM client:
Step
1. Enter system view.
2. Enter VAM client view.
3. Set the retry timer and retry
times.

Setting the dumb timer for a VAM client

A VAM client starts the dumb timer after the timeout timer expires. The client does not process any
packets during the dumb time. When the dumb timer expires, the client sends a new connection
request to the VAM server.
To set the dumb timer for a VAM client:
Step
1. Enter system view.
