Multicast Scaling for BlackDiamond 20808 Switches
Running ExtremeXOS 12.3.1
Following are multicast scaling number recommendations for BlackDiamond 20808 systems running
ExtremeXOS 12.3.1 software:
● It is recommended that you not exceed 3,700 (S, G) multicast streams in a BlackDiamond 20808
switch. If incoming streams are received via a load shared link, it is recommended that the scaling
numbers be 2,000 entries and, along with the maximum number of link aggregation ports, not
exceed four per group. This number will vary per link aggregation groups.
● It is recommended that you not exceed 3,770 egress interfaces (group subscribers) for all (S, G)
entries for each of the following port pair combinations:
-1G module
First pair: ports 1 through 10, 21 through 30
Second pair: ports 11 through 20, 31 through 40
- 10G module
First pair: ports 1, 3
Second pair: ports 5, 7
Third pair: ports 6, 8
Fourth pair: ports 2, 4
That is, when a 1G module is used, make sure the total number of egress interfaces in the 1G
module for all (S, G) entries does not exceed 3,776 for the port pair combination. When a 10G
module is used, it is recommended that you make sure the total number of egress interfaces in the
10G module does not exceed 3,776 for all (S, G) entries.
● It is recommended that you not exceed 128 egress interfaces per port for both 1G and 10G modules.
