Priority is | * | | determined by standard QoS functions. | * | | 01 = Change packet priority to P[2:0] if it is greater than | * | | QoS result. | * | | 10 = Change packet priority to P[2:0] if it is smaller than | * | | the QoS result. | * | | 11 = Always change packet priority to P[2:0]. | * +----------------+-----------------------------------------------------------------+ * | P[2:0] | Priority value | * +----------------+-----------------------------------------------------------------+ * | RPE | Remark Priority Enable | * | | 0 = Disable priority remarking | * | | 1 = Enable priority remarking. VLAN tag priority (PCP) bits are | * | | replaced by RP[2:0]. | * +----------------+-----------------------------------------------------------------+ * | RP[2:0] | Remarked Priority value | * +----------------+-----------------------------------------------------------------+ * | MM[1:0] | Map Mode | * | | 00 = No forwarding remapping | * | | 01 = The forwarding map in FORWARD is OR'ed with the forwarding | * | | map from the Address Lookup Table. | * | | 10 = The forwarding map in FORWARD is AND'ed with the forwarding| * | | map from the Address Lookup Table. | * | | 11 = The forwarding map in FORWARD replaces the forwarding map | * | | from the Address Lookup Table. | * +----------------+-----------------------------------------------------------------+ * | FORWARD[N-1:0] | Forwarding Ports | * | | Bit 0 corresponds to port 1, Bit 1 corresponds to port 2, etc. | * | | 0 = Do not forward to this port | * | | 1 = Forward to this port | * +----------------+-----------------------------------------------------------------+ * * * TABLE 4-22: ACL ACTION RULE PARAMETERS FOR COUNT MODE (MD = 01 OR ENB = 00) * * | Parameter | Description | * +--------------+-----------------------------------------------------------------+ * | COUNT[10:0] | Count value | * +--------------+-----------------------------------------------------------------+ * | TU | Time unit for counter. | * | | 0 = Microseconds | * | | 1 = Milliseconds | * +--------------+-----------------------------------------------------------------+ * | CA | Counter Algorithm. | * | | 0 = An 11-bit counter will be loaded with the count value from | * | | the list and start counting down every unit time. An | * | | interrupt will be generated when the timer expires, i.e. | * | | the next qualified packet has not been received within the | * | | period specified by the value. | * | | 1 = The counter is incremented with every matched packet | * | | received. An interrupt is generated when the terminal count | * | | is reached. The count resets thereafter. Time units are not | * | | used in this mode. | * +--------------+-----------------------------------------------------------------+ * * Figure 4-8 shows basic organization of the ACL Table. The table has 16 entries, and each entry includes a matching * field, action field and process field. Although these fields are stored together in one table, it is important to note that for * a given table entry, the Matching, Action and Process fields generally do not form an associated group. The one excep- * tion is when the Matching Rule is in Count Mode (MD = 01 and ENB = 00). In that case, the Matching and Action fields * are used in tandem. * * * FIGURE 4-8: ACL TABLE FORMAT * * +----------+----------+----------+--------------------+-------------+------------+ * | ENTRY #15| ENTRY #..| ENTRY #..| ENTRY #.. | ENTRY #1 | ENTRY #0 | * +----------+----------+----------+--------------------+-------------+------------+ * * ---------------------------------------------------------------------------------- * MODUS 1: MD=01 ENB=00 (Layer 2 Counter) * ---------------------------------------------------------------------------------- * | FRN[3:0] | MD[1:0]|ENB[1:0]|S/D/EQ| MAC ADDRESS [47:0] | TYPE [15:0] | COUNT[10:0]| TU/CA/Res | RULESET [15:0] | * ---------------------------------------------------------------------------------- * ^ * PROCESS Field MATCHING Rule ACTION Rule * ---------------------------------------------------------------------------------- * * * ---------------------------------------------------------------------------------- * MODUS 2: MD=01 ENB!=00 (Layer 2 Forwarding) * ---------------------------------------------------------------------------------- * | FRN[3:0] | MD[1:0]|ENB[1:0]|S/D/EQ| MAC ADDRESS [47:0] | TYPE [15:0] | PM[1:0]|P[2:0]|RPE/RP[2:0]|MM[1:0]|FORWARD[#ports]| RULESET [15:0] | * ---------------------------------------------------------------------------------- * * * ---------------------------------------------------------------------------------- * MODUS 3: MD=10 (Layer 3 IP) * ---------------------------------------------------------------------------------- * | FRN[3:0] | MD[1:0]|ENB[1:0]|S/D/EQ| IP ADDRESS [31:0] | IP MASK [31:0]| PM[1:0]|P[2:0]|RPE/RP[2:0]|MM[1:0]|FORWARD[#ports]| RULESET [15:0] | * ---------------------------------------------------------------------------------- * * * ---------------------------------------------------------------------------------- * MODUS 4: MD=11 (Layer 4 TCP/UDP) * ---------------------------------------------------------------------------------- * | FRN[3:0] | MD[1:0]|ENB[1:0]|MAX PORT|MIN PORT|Resvd(5)|PC[1:0]|PRO[7:0]|FME/FMSK/FLAG| PM[1:0]|P[2:0]|RPE/RP[2:0]|MM[1:0]|FORWARD[#ports]| RULESET [15:0] | * ---------------------------------------------------------------------------------- * */ }
