resources to SAPs associated with a ingress filter policy using this criteria, as long as the total amount
of resources allocated does not exceed the resources allocated to ingress filter policies (configured
with the command config> system> resource-profile> ingress-internal-tcam> acl-sap-ingress
command) and chunks are available for use.
NOTE: In 7210 SAS-D, mac-criteria SAP ingress QoS policies get to use an additional 128
classification entries with 64 meters. These entries are allocated to mac-criteria SAP ingress QoS
resource pool by default and cannot be reassigned to any another feature or any other match criteria.
dhcp-snooping-enable
Syntax [no] dhcp-snooping-enable
Context configure>system>resource-profile>ingress-internal-tcam
Description Platforms Supported: 7210 SAS-E only.
This command allows the user to allocate resources for use by DHCP snooping features from the
ingress internal TCAM resource pool. Before using the dhcp-snooping feature, user must allocate
resources to it using this command, else software will disallow configuration of DHCP snooping
command under the service. To allocate resources to the dhcp snooping features, user will need to
reduce the resources used by other features, such as ingress ACLs, or SAP ingress QoS, or others,
which have been allocated resources from the ingress internal tcam resource pool and allocate it to
this feature. Executing this command allocates only a single chunk of resources for use by dhcp-
snooping feature.
The command tools>dump> system-resources can be used to check the resource usage. The sample
output below shows that a single slice with 256 entries has been allocated to the DHCP snooping
feature.
| Total | Allocated | Free
-------------------------------+-----------+-----------+------------
>> DHCP Snooping Sap Entries | 251| 50| 250
With the no form of the command, software does not allocate any resources for use by dhcp snooping
feature and the feature cannot be used any more. A reboot is required after executing the no form of
the command for it to take effect.
