Parameters
Usage Recent software enhancements required to the intercommunication protocols made
2.0 incompatible with version 1.2. To remedy this situation, version 2.1 of the HP
EFS WAN Accelerator supports both the new intercommunication protocols as well
as the 1.2 intercommunication protocols.
Version 2.1 HP EFS WAN Accelerators do not require any configuration changes
because the 2.1 appliances understand the protocols used in the 1.2 appliances.
However, as the client-side HP EFS WAN Accelerator, by default the 2.1 HP EFS
WAN Accelerator will initiate connections with the server-side HP EFS WAN
Accelerator using the new version 6 service protocol. This disrupts connectivity with
any 1.2 server-side HP EFS WAN Accelerator peers. To remedy this situation, 2.1 HP
EFS WAN Accelerators allow you to configure the version of the service protocol
using the IP address for each peer when initiating HP EFS WAN Accelerator to HP
EFS WAN Accelerator connections. To configure the protocol version, the following
CLI commands must be issued for each 1.2 HP EFS WAN Accelerator peer in the
network:
sh> peer <addr> version min 5
sh> peer <addr> version max 5
These CLI commands instruct the 2.1 HP EFS WAN Accelerator to use only the
version 5 protocols when initiating service connections.
<IP addr> Specifies the in-path or out-of-path (or both) HP EFS WAN
Accelerator.
min <version> Specifies the protocol version number: 5 or 6.
max <version> Specifies the protocol version number: 5 or 6.
