HP STORAGEWORKS EFS WAN ACCELERATOR COMMAND-LINE INTERFACE REFERENCE MANUAL 107
4 - CONFIGURATION-MODE
C
OMMANDS
to set which VLAN to use when the HP EFS WAN Accelerator communicates with
another HP EFS WAN Accelerator. It does not define which VLAN to optimize. To
define which VLAN to optimize, you must define in-path rules and apply them to all
VLANs or a specific VLAN.
The no command option disables the VLAN support.
Syntax [no] in-path interface <interface> vlan tag <id>
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 [no] in-path kickoff
Parameters None
Example
minna (config) # in-path kickoff
minna (config) #
in-path neighbor allow failure
Description Enables the HP EFS WAN Accelerator to continue to optimize connections even
when one or more of it’s configured neighbors is unreachable.
When you deploy the HP EFS WAN Accelerator in an in-path deployment with
connection forwarding, you want the HP EFS WAN Accelerator to stop intercepting
traffic if it cannot contact its neighbor. In deployments with multiple WCCP clusters
or Interceptor appliance masters and backups, the in-path neighbor allow failure
command enables the HP EFS WAN Accelerator to continue to intercept connections
if one or more of it’s configured neighbors is unreachable.
<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).
