Note
This procedure only applies to 5320 Series and 5420 Series.
Perform this procedure to increase the number of SPB nodes per area that the switch supports. For more information about maximum scaling numbers, see Fabric Engine Release Notes.
If you enable this boot config flag, it decreases the scaling limits for the following features:
Switched UNI (S-UNI) endpoints
Layer 2 and Layer 3 I-SIDs
IP Multicast over Fabric Connect local streams
Private VLANs
The scaling numbers for the following items are limited by the use of a shared hardware resource, and thus they affect one another:
the number of SPB nodes per area
the number of SPB nodes that send IP Multicast streams that the local BEB receives
local SPB services:
Layer 2 I-SIDs
Layer 3 I-SIDs
IP Multicast over Fabric Connect remote IP Multicast stream data I-SIDs
I-SID mirroring instances
