OS6900 and OS10K tables
MC_CONTROL_5
Display the MC_CONTROL_5 register:
Note:
Only applicable to AOS7 hardware platform
BCM.0> getreg MC_CONTROL_5
MC_CONTROL_5.ipipe0[0xc180609]=0x2001000:
<SHARED_TABLE_L2MC_SIZE=0x1000,SHARED_TABLE_IPMC_SIZE=0x1000>
L2MC table
Note:
Only applicable to AOS7 hardware platform
If the destination MAC address is a multicast address, then the result of the destination lookup is a 10-bit index
(L2MC_PTR) into this table. The result of the direct index into the L2 multicast table is a bitmap that indicates
which ports on the local switch should receive the packet. The MC Port Bitmap is qualified with the VLAN bitmap.
The MC Port bitmap is picked up from the L2MC table.
Default "L2MC Table":
BCM.0> d chg l2mc
L2MC.ipipe0[0]: <VALID=1,PORT_BITMAP_W1=0x400000,PORT_BITMAP=0x0040000000000000,>

L3_IPMC table
Note:
Only applicable to AOS7 hardware platforms
The index into this table is specified by L3MC_INDEX bits in the L3_ENTRY tables.

A new entry is added to this table when a new IPMS forwarding entry is created (an example):
