These bits indicate the port(s) associated with this MAC address. When bit

 

 

 

18 is cleared, a single port is selected. When bit 18 is set, multiple ports are

 

 

 

selected.

MAC Address

 

 

R/W

0000h

 

These field contains the last 16 bits of the ALR entry that will be written into

 

 

 

the ALR table. They correspond to the last 16 bits of the MAC address. Bit

 

 

 

15 holds the MSB of the last byte (the last bit on the wire). The first 32 bits

 

 

 

of the MAC address are located in the Switch Engine ALR Write Data 0

 

 

 

Register (SWE_ALR_WR_DAT_0).
