ip csg iscsi drain delay
ip csg iscsi drain delay
To define the delay interval, in seconds, before draining packets from the Storage Area Network (SAN)
connected to the Internet Small Computer Systems Interface (iSCSI) when the Billing Mediation Agent
(BMA) becomes active, use the ip csg iscsi drain delay command in global configuration mode. To
delete the drain delay interval, use the no form of this command.
ip csg iscsi drain delay number-of-seconds
no ip csg iscsi drain delay

Defaults
The default value is 1 second.

Usage Guidelines
The CSG2 can buffer GTP’ messages in the Storage Area Network (SAN) connected to the Internet
Small Computer Systems Interface (iSCSI), if so configured. (For more information, see the
“Configuring iSCSI Support” section on page 8-1
.) By default, the CSG2 limits the rate at which GTP’
messages are read from the SAN to 167 packets/second (500 packets/3 seconds). However, you can use
the ip csg iscsi drain delay command to change that rate. For example, specifying an interval of
2 seconds yields a rate of 250 packets/second (500 packets/2 seconds).
Examples
The following example shows how to specify a SAN drain delay interval of 2 seconds:
ip csg iscsi drain delay 2
Related Commands
number-of-seconds
Delay interval, in seconds, before draining packets from the SAN. The
range is 0 to 3. The default value is 1. A value of 0 means no delay.

Network (SAN) connected to the Internet Small Computer Systems
Interface (iSCSI) per drain delay interval when the Billing
Mediation Agent (BMA) becomes active.
Specifies the Internet Small Computer Systems Interface (iSCSI)
target to be used as backup storage for the CSG2.
Creates an iSCSI profile for an iSCSI target on the CSG2, and enters
iSCSI configuration mode.
