Description (partial)


The CSG2 may run out of I/O memory on one or more Traffic Processors.

Output of <CmdBold> show mem | include <CmdArg> I/O <NoCmdArg><NoCmdBold>
will indicate this.


This is triggered by a large number of small "set-aside" packets. These are data plane packets
that are temporarily queued waiting for some event such as a User Profile respone, Quota fetch response etc. This may be encountered in cases where the CSG2 is operated beyond the
supported traffic parameters (such as number of sessions, subscribers etc) and/or cases where
an external network entity such as a Quota Server is not able to keep up with the control traffic.

<CmdBold> show ip csg stat | include <CmdBold> set aside <NoCmdBold> displays the number
of set aside packets in the system.
