▀ ip pool
▄ Command Line Interface Reference, StarOS Release 18
2566
users_per_ip
: Specifies how many users can share a single NAT IP address.
users_per_ip
must be an integer from 2 through 2016.
alert-threshold
: Specifies the alert threshold for the pool:
Important:
Thresholds configured using the
alert-threshold
keyword are specific to the pool that they are
configured in. Thresholds configured using the
threshold ip-pool-*
commands in the Context Configuration Mode
apply to all IP pools in that context, and override the threshold configurations set within individual pools.
pool-free
: Percentage free alert threshold for this pool
pool-hold
: Percentage hold alert threshold for this pool
pool-release
: Percentage released alert threshold for this pool
pool-used
: Percentage used alert threshold for this pool
low_thresh
: The IP pool utilization percentage that must be met or exceeded within the polling
interval to generate an alert or alarm.
low_thresh
must be an integer from 0 through 100.
clear high_thresh
: The IP pool utilization percentage that maintains a previously generated alarm
condition. If the utilization percentage rises above the high threshold within the polling interval, a
clear alarm is generated.
clear alarm is generated.
high_thresh
must be an integer from 0 through 100.
Important:
The
high_thresh
value is ignored for the Alert model. In addition, if this value is not configured
for the Alarm model, the system assumes it is identical to the low threshold.
max-chunks-per-user max_chunks_per_user
: Specifies the maximum number of port chunks to
be allocated per subscriber in the many-to-one NAT pool.
max_chunks_per_user
must be an integer from 1 through 2016.
Default: 1
nat-binding-timer binding_timer
: Specifies NAT Binding Timer for the NAT pool.
timer
must be an integer from 0 through 31556926. If set to 0, is disabled. Default: 0
nat-pkt-drop-threshold high_thresh [ clear low_thresh ]
: Specifies the NAT packet
drop threshold in percentage (%).
high_thresh
specifies the high NAT packet drop percentage threshold, and must be an integer
from 0 through 100. Default: 0
clear low_thresh
specifies the low NAT packet drop percentage threshold, and must be an
integer from 0 through 100. Default: 0
nexthop-forwarding-address address
: Specifies the nexthop forwarding address for this pool.
address
must be an IPv4 or IPv6 address. If configured for a NAT pool, packets that are NATed
using that NAT pool will be routed based on the configured nexthop address.
Important:
The
nexthop-forwarding-address
support for NAT IP pools is functional only in later releases
of Release 9.0 and in 10.0 and later releases.
on-demand
: Specifies allocating IP when matching data traffic begins.
port-chunk-size size
: Specifies NAT port chunk size (number of NAT ports per chunk) for many-
to-one NAT pool.
