Important:
In UMTS deployments, on upgrading from Release 8.1 to Release 9.0, and in CDMA deployments,
on upgrading from Release 8.1 to Release 8.3, all NAT realms configured in Release 8.1 using the
nat-realm
keyword
must be reconfigured using either the
nat-one-to-one
(for one-to-one NAT realms) or the
napt-users-per-ip-
address
(for many-to-one NAT realms) keywords.
Configures one-to-one NAT realm.
alert-threshold
: Specifies alert threshold for this pool:
Important:
Thresholds configured using the
alert-threshold
keyword are specific to the pool in which they
are configured. Thresholds configured using the
thresholdip-pool *
commands in the Context Configuration Mode
apply to all IP pools in the 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.
nat-binding-timer nat_binding_timer
: Specifies NAT Binding Timer for the NAT pool.
binding_timer
must be an integer from 0 through 31556926. If set to 0, is disabled.
Important:
For many-to-one NAT pools, the default NAT Binding Timer value is
60 seconds. For one-to-one NAT pools, it is 0. By default, the feature is disabled—the IP
addresses/ port-chunks once allocated will never be freed.
addresses/ port-chunks once allocated will never be freed.
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 ip_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 Release9.0 and in Release 10.0 and later releases.
