Memory Partitions
You can specify how much memory the OSPF protocol can use for its data
processing and storage from the Administration Console.
Displaying Memory
Partitions
You can display a module’s OSPF memory allocation. From the top level of
the Administration Console, enter:
ip ospf partition display
This example shows an OSPF memory partition summary:
This display shows three partition parameters:
■
Current partition maximum size
(
500000
in this example) —
The OSPF memory limit implemented at the last system reboot
■
Configured partition maximum size
(
500000
in this example) —
The last value that you entered, which becomes the current partition
maximum size at system reboot
■
Allocated partition size
(
100000
in this example) — The module’s
current working memory. OSPF dynamically allocates memory in
100,000-byte chunks up to the current partition maximum size.
If the system shows a partition size of
0
, the OSPF protocol is using the
CoreBuilder 2500 system memory partition.
Modifying Memory
Partitions
Use this command to change the OSPF memory allocation. This change
takes effect at system reboot. To modify a module’s OSPF memory
allocation:
1
From the top level of the Administration Console, enter:
ip ospf partition modify
2
Enter the new partition size (in bytes).
Example:
Maximum partition size is 8443220 bytes
Enter new partition maximum size (in bytes) [500000]: 600000
New partition size will take effect after reboot.
The maximum partition size (
8443220
in this example) shows how much
total memory is available to define as the OSPF maximum partition.
