OMMANDS
Parameters
Example
minna (config) #in-path interface in_path0_0 vlan 26
minna (config) #
in-path kickoff
Description Resets open connections upon start up. The no command option disables the in-path
kickoff feature.
When the HP EFS WAN Accelerator is not powered on or the HP EFS WAN
Accelerator service is not running, the failover HP EFS WAN Accelerator takes over
so that connections continue to be made to the WAN. With kickoff enabled, when the
HP EFS WAN Accelerator service starts, it breaks existing connections and forces
clients to open a new connection. With kickoff disabled, open connections are not
broken but they are unoptimized—new connections are optimized.
Syntax in-path kickoff
Parameters None
Example
minna (config) # in-path kickoff
minna (config) #
in-path neighbor enable
Description Enables connection forwarding support in asymmetric networks. Connection
forwarding forwards Transmission Control Protocol (TCP) connections in networks
where the path from the client to the server is different from the server to the client.
The no command option disables connection forwarding support.
If you have one path from the client to the server and a different path from the server
to the client, you need to enable in-path connection forwarding so that the HP EFS
WAN Accelerators can communicate with each other. These HP EFS WAN
Accelerators are called neighbors and exchange connection information to redirect
packets to each other.
IMPORTANT: When you define a neighbor, you must specify the HP EFS WAN Accelerator
in-path IP address, not the primary IP address.
Neighbors can be placed on the same physical site or on different sites but the latency
between them must be small because the packets travelling between them are not
optimized.
<interface> Specifies the in-path HP EFS WAN Accelerator for which the
VLAN applies.
<id> Specifies the VLAN identification number. The VLAN
identification number is a value with a range from 0-4094 (0
specifies no tagging).
