Field Description
Cells
Basic unit of allocation in the TCAM. A cell is 72 bits in
length. Each cell has an associated value, plus a mask, and
result—referred to as VMR. Cells are grouped in one of three
sizes:
•
1—72 bits
•
2—144 bits
•
4—288 bits
Entry
Group of cells that together make a single lookup entry. For
example, a standard ACL uses a 72-bit entry because the
number of bits from a packet that compose a lookup fits
within 72 bits. An extended ACE usually fits within 144 bits
(a two-cell grouping). Exceptions to this are ACEs that use a
match on a port range and ACEs that match on multiple TCP
flag states.
Regions
Pool of cells that are set aside for a specific application. All
entries in a region have the same grouping size of cells (1, 2,
or 4 cells. All regions are dynamically sized with no
minimum—one region can use free entries from another
region if they have the same size.
Command
