Usage Guidelines
Having 200 source ports allows up to 256*200 authentication and accounting requests to be outstanding at
one time. During peak call volume, typically when a router first boots or when an interface flaps, the extra
source ports allow sessions to recover more quickly on large-scale aggregation platforms.
To use this command, you must be in a user group associated with a task group that includes appropriate task
IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator
for assistance.
