Valid
This bit is cleared when the Get First Entry or Get Next Entry bits of the
Switch Engine ALR Command Register (SWE_ALR_CMD)
bit is set when a valid entry is found in the ALR table. This bit stays cleared
when the top of the ALR table is reached without finding an entry.
End of Table
This bit indicates that the end of the ALR table has been reached and further
Get Next Entry commands are not required.
Note:
Static
Indicates that this entry will not be removed by the aging process. When this
bit is cleared, this entry will be automatically removed after 5 to 10 minutes
of inactivity. Inactivity is defined as no packets being received with a source
address that matches this MAC address.
Filter
When set, indicates that packets with a destination address that matches
this MAC address will be filtered.
Priority
These bits indicate the priority that is used for packets with a destination
address that matches this MAC address. This priority is only used if the
Static bit of this register is set, and the DA Highest Priority (bit 5) in the
Switch Engine Global Ingress Configuration Register
(SWE_GLOBAL_INGRSS_CFG)
Switch Engine ALR Read Data 1 Register (SWE_ALR_RD_DAT_1)
This register is used in conjunction with the
(SWE_ALR_RD_DAT_0)
loaded via the Get First Entry or Get Next Entry commands in the
Register
set.
The Valid bit may or may not be set when the end of the table is
reached.
Register #:
(SWE_ALR_CMD). This register is only valid when either of the Valid or End of Table bits are
to read the ALR table. It contains the last 32 bits of the ALR entry and is
