In this example, (assuming a SAP with an ingress ACL policy that uses ipv6-64-
bit criteria is configured), as no additional chunks are available, mac-criteria
cannot allocate more than 1 chunk (even if the max keyword is specified). The
system fails the configuration if the number of ACL entries with mac-criteria
exceeds the limit of 1 chunk allocated to SAP ingress ACL mac-criteria (that is,
the system does not allocate more than the configured limit of 3 chunks = 1 for
mac-criteria + for ipv4-criteria + 1 for ipv6-criteria).
• A chunk is allocated for use by SAP ingress ACL entries that use ipv6-64-bit
criteria when the user associates an ingress ACL policy (with ipv6-64-bit-criteria
entries defined) with a SAP. Because the max keyword is specified, the system
can allocate more chunks, if a chunk is available for use.
In this example, as there are no more chunks available, ipv6-64-bit criteria
cannot allocate more than 1 chunk (even if the max keyword is specified). The
system fails the configuration when the number of ACL entries with ipv6-64-bit
criteria exceeds the limit of one chunk allocated to SAP ingress ACL match (that
is, the system does not allocate more than the configured limit of 3 chunks = 1
for mac-criteria + 1 for ipv4-criteria + 1 for ipv6-64-bit criteria).
• The system fails any attempt to use SAP ingress ACLs with ipv6-128 bit match
criteria (and the other combinations listed above), because the user has
disabled these criteria.
In Example 2, the user can run no ipv4-match-enable command to disable the use
of ipv4-criteria. The system checks for SAPs that use ipv4-criteria and if found, fails
the command; otherwise, the chunk freed for use with either mac-criteria or ipv6-64-
bit criteria. The entire chunk is allocated to mac-criteria if the first SAP that needs
resources requests for mac-criteria and no entries in the chunk are already allocated
to mac-criteria, which leaves no resources for use by ipv6-64-bit criteria. In the same
way, the entire chunk is allocated to ipv6-64-bit criteria, if the first SAP that needs
resources requests for ipv6-64-bit criteria and no entries in the chunk are already
allocated to ipv6-64-bit criteria, which leaves no resources for use by mac-criteria.
6.8.4 7210 SAS-R6 and 7210 SAS-R12 Configuration
Guidelines for System Resource Profile
The following configuration guidelines apply to 7210 SAS-R6 and 7210 SAS-R12.
• The user can change the system-resource policy attached to a card/IMM in the
following cases:
- when the card/IMM state is unprovisioned
- when the card/IMM is provisioned but not equipped
