3.5.4 Distribution of entries when custom is specified
The receive-side flow detection mode custom is a flow detection mode in which the following functions can be selected in units of entry blocks in the hardware table:
-
Filters
-
QoS
-
Policy-Based Mirroring
-
DHCP snooping terminal filters
The entry block has eight areas (numbers 1 to 8). The number of entries that can be used is determined for each function assigned to the entry block. When assigning the same function to multiple entry blocks, you can select only contiguous blocks of entries. In this case, the total number of entries that can be used in the corresponding entry block is the capacity limit for that function.
The following table describes the receive side flow detection functions assigned to the entry block and the number of entries that can be used when each function is assigned.

- Note #1
-
When IP not set VLAN suppression mode is used together, functions cannot be assigned to entry blocks 5 and 6. For details about IP not set VLAN suppression mode, see the Configuration Guide Vol.2" "1.1.3 Receiver Flow-Detection Mode.
- Note #2
-
Filtering IPv6 criteria, QoS,, and policy-based mirroring use two entry-blocks in a single feature.
- Note #3
-
For DHCP snooping terminal filters, the capacity limit is the sum of the number of entries in the allocated entry block minus 2. Any entry in the entry block that exceeds the maximum number of entries in the binding database is an unused entry.
