The Cisco AS5350XM or Cisco AS5400XM universal gateway displays every asynchronous interface it
recognizes. Therefore, if your system has a large number of asynchronous interfaces, the running
configuration will be very long. To aggregate the asynchronous interfaces, you must assign them to a
group-async interface using the command
group-range
. See the
“Configuring the Asynchronous Group
Interface” section on page 6
.
Group-async interfaces are templates used to control the configuration of multiple asynchronous
interfaces on the gateway. Each asynchronous interface corresponds to one of the modem lines and uses
the same number as its corresponding line. Configuring the asynchronous interfaces as a group-async
interface saves you time and configuration file size.
Investigating Memory Usage
Use the
show memory summary
command to perform these tasks:
•
Understand how memory is used for different processor and I/O memory processes.
•
Identify memory fragmentation and memory leaks.
–
Memory leak—Memory that is not released back to the processor. Memory leaks are indicated
by steady decreases of free memory. However, the preferred way to track memory leaks is to
monitor the FreeMem variable in the OID MIB (object-identifier Management Information
Base).
–
Memory fragmentation—Memory that is indicated by the largest block of memory not being
equal to the lowest block. Fragmentation increases as the numbers grow further apart.
