3Com 10014298 manual Setting the Lower Limit and the Safety Value Simultaneously

106CHAPTER 5: IP ROUTING PROTOCOL OPERATION

If automatic memory restoration is enabled, when the free memory of the

Ethernet switch exceeds the safety value, the disconnected routes will be restored.

Perform the following configurations in system view.

By default, the safety value of the Ethernet switch memory is 4Mbytes.

The safety value of the memory must be larger than the lower limit value.

Setting the Lower Limit and the Safety Value Simultaneously

When you need to modify both the lower limit and the safety value of the Ethernet switch memory, 3Com recommends that you modify the two configurations simultaneously.

You can also restore the lower limit and the safety value of the Ethernet switch memory to the default value at the same time if it is necessary.

Perform the following configuration in the system view.

The default values of the lower limit and the safety value of the Ethernet switch memory are 2Mbytes and 4Mbytes, respectively.

Note that safety-valuemust have a higher value than limit-value.

Preventing Automatic Recovery of Disconnected Routing Protocols

If the automatic memory restoration function of a Ethernet switch is disabled, connection of routing protocols will not be restored even if the free memory returns to the safety value.

Perform the following configurations in system view.
