The pktcEScTapStreamInterceptEnable field can be modified when a tap is active to enable or disable intercept delivery
for that stream.
All other tap parameters must be changed from the MD by completely removing and reinstalling the tap session in the
TAPMIBs.
The MD should not change the pktcEScTapMediationNotificationEnable field to false as this will disable tap stream
notifications and may result in:
The C4 CMTS may initially accept a new tap stream, returning a successful SNMP response message, but will later
fail to enable the tap stream.
A pktESTapMediationDebug notification is the only mechanism for the MD/operator to be notified that the tap
operation failed.
