HP StorageWorks Enterprise File Services WAN Accelerator 2.1.7 Command-Line Interface Reference Manual (392361-004, June 2006)

HP STORAGEWORKS EFS WAN ACCELERATOR COMMAND-LINE INTERFACE REFERENCE MANUAL 99

C
OMMANDS
Appliances in a cluster process the peering rules you specify in a spill-over fashion.
When the maximum number of TCP connections for an HP EFS WAN Accelerator is
reached, that appliance stops intercepting new connections and passes them on to the
next HP EFS WAN Accelerator in the cluster (as defined by the peer rule that you set).
This process continues until there are no more HP EFS WAN Accelerators available in
the cluster.
In serial cluster or cascade deployments:
 A cluster can be created on either the client side or on the server side.
 The peering rules table is a ordered list of rules and the first rule that matches the
rule is applied.
 In the case of a cascade cluster, only pass-through peering rules are used.
 To block interceptions on inner connections created by other HP EFS WAN
Accelerators in the same cluster, in-path rules are specified to pass-through
connections originating from those HP EFS WAN Accelerators.
For detailed information about how to configure serial cluster deployments, see the HP
StorageWorks Enterprise File Services WAN Accelerator Deployment Guide.

Parameters
Example
minna (config) # in-path peering rule pass peer 10.0.1.2 rulenum 1
minna (config) # in-path peering rule pass peer 10.0.1.3 rulenum 1
minna (config) # in-path rule pass-through src 10.0.1.2/32 rulenum 1
minna (config) # in-path rule pass-through src 10.0.1.3/32 rulenum 1
minna (config) # in-path peering move-rule 3 to 1
minna (config) #
auto | pass | accept Specifies the rule type:
• auto. Automatically determines the response for peering
requests (performs the best peering possible).
• pass. Passes through all matching peering requests (never peers
with the HP EFS WAN Accelerator before this HP EFS WAN
Accelerator).
• accept. Accepts matching peering requests (
peer <peerip> Specifies the peer HP EFS WAN Accelerator IP address.
src <subnet> Specifies the source network for this rule.
dst <subnet> Specifies the destination network for this rule.
dst-port <port |
portlabel>
Specifies the destination port for this rule. You can specify all for
all ports or a port label. For detailed information about port
labels, see “port-label” on page 130.
rulenum <rulenum> Specifies the rule number.
