Is this correct? You compare the last 23 bits of the base multicast address
to the given multicast ip addres, like below, as mentioned in TCP/IP vol 2
page 402.
Multicast IP: 224.10.10.10 =11100000 0 0001010 00001010 00001010
Hex =(E0 0A 0A 0A)
Base MAC Add: 0100.5E00.0000 =000000001 0 0000000 0000000 00000000
Hex =(01 00 5E 00 00 00)
Resulting Multicast Mac Addr =000000001 00001010 00001010 00001010
Hex =01-00-5E-0A-0A-0A
So the need comand is?
set cam permanent 01-00-5E-0A-0A-0A 2/1-2 100

Subject: CAM Table config for Multicast
I want to configure a permanent CAM table entry for ports (2/1, 2/2) in vlan
100 for a multicast group 224.10.10.10. The help feature on my cat5000 has
the following command:
set cam <static|permanent> <multicast_mac> <mod/ports..> [vlan]
My question is, what is <multicast_mac>? Is it the mac address of the
router? If it is not how do I detremine it. All I have is just the
multicast IP address.
Thanks
