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.
If there are more than two possible paths, additional HP EFS WAN Accelerators must
to be installed on each path and configured as neighbors. Neighbors are notified in
parallel so that the delay introduced at connection setup is equal to the time it takes to
get an acknowledgement from the furthest neighbor.
For detailed information about connection forwarding deployments and how to
configure them, see the HP StorageWorks Enterprise File Services WAN Accelerator
Deployment Guide.
Syntax in-path neighbor enable
Parameters None
Example
minna (config) # in-path neighbor enable
minna (config) #in-path neighbor ip-address 10.0.0.4
;;client-side appliance (HP EFS WAN Accelerator-1)
minna (config) #in-path neighbor ip-address 10.0.0.6
;;the server-side appliance (HP EFS WAN Accelerator-2)
in-path neighbor ip address
Description Sets the IP address for the neighbor HP EFS WAN Accelerator for connection
forwarding. The no command option removes the IP address for the neighbor HP EFS
WAN Accelerator from the connection forwarding list.
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 and configure the HP
EFS WAN Accelerators to know about and communicate with each other. These HP
EFS WAN Accelerators are called neighbors and exchange connection information to
redirect packets to each other. For example:
minna (config) # in-path neighbor enable
minna (config) #in-path neighbor ip-address 10.0.0.4
;;client-side appliance (HP EFS WAN Accelerator-1)
minna (config) #in-path neighbor ip-address 10.0.0.6
;;the server-side appliance (HP EFS WAN Accelerator-2)
