Viewing I-SID maximum MAC-limit
Perform this procedure to view the maximum MAC learning limit information for an I-SID.

Important
The command show i-sid limit-fdb-learning is supported only on the VSP 4450 Series.
About this task
The total MAC learning limit per switch is 32000. MAC learning on I-SID stops when the maximum limit is reached.
Procedure
show i-sid limit-fdb-learning <1-16777215>
Example
View maximum MAC learning limit for all I-SIDs.
