CONFIG Commands

v Less than 78 characters and is case sensitive

v Set before storing the router's con®guration memory in IBD.

inactivity-timer #_of_min

Changes the setting of the Inactivity Timer. The Inactivity Timer logs out a

user if the remote or physical console is inactive for the period of time

speci®ed in this command. This command affects only consoles that require

login. The default setting of 0 turns the inactivity timer off, indicating that no

logoff is performed, no matter how long a console remains inactive.

input-low-waterinterface# low_ #_of_receive_buffers

Allows you to con®gure the value of the low number of receive buffers, or

packets, on a per-interface basis, thus overriding the default values.

The memory allocation strategy changes to conserve buffers when the

number of free buffers is equal to or less than the low or low-water mark

value. When a packet is received, and the current value of the interface is

less than the low water value, then that packet is eligible for ¯ow control

(dropping).

The range of values is 1 to 255. The default is both platform and device

speci®c. Setting the value to 0 restores the autocon®gured default.

Interface# is the number of the interface you are con®guring.

Low_#_of_receive_buffers is the low water value.

Lowering the value will make it less likely that packets from this interface

will be dropped when sent on congested networks. However, lowering the

value may negatively affect performance if it drops packets to the extent

that the receive queue is frequently empty. Raising the value has the

opposite effect.

Type the QUEUE or BUFFER command at the GWCON prompt (+) to show

the low setting.

location sysLocation

Sets the physical location of an SNMP node. There is a limit of 80

characters for the sysLocation name length. This variable is for information

purposes only and has no effect on router operation. It is useful for SNMP

management identi®cation of the system.

logging disposition setting

Changes the SRAM record for the default logging disposition. This

command affects the MONITR process (that is, it changes the default

setting at startup).

The logging disposition settings are as follows:

v console writes to the console (equivalent to the OPCON divert 2 0

command).

v detached holds the data and does not print it (equivalent to the OPCON

halt 2 command).

v ¯ush discards the data (equivalent to the OPCON ¯ush 2 command).

If you have a printing terminal attached to the router's console port, you can

obtain a hard copy of the startup messages by setting the logging

disposition to console, and restarting the router.

packet-sizemax_packet_size_in_bytes

Establishes or changes the maximum size for global buffers and receive

buffers. If you specify a value of 0 as the maximum packet size, the size of
