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

Note: The data-link parameter cannot be changed for integrated modems.

down-notifyinterface# # of seconds

Allows the user to specify the number of seconds before declaring an

interface as being down. The normal maintenance packet interval is 3

seconds, and it takes four maintenance failures to declare the interface as

down.

The set down-notifycommand is used primarily when tunneling LLC traffic

over an IP network using OSPF. If an interface goes down, OSPF cannot

detect it fast enough because of the length of time that it takes for an

interface to be declared down. Therefore, LLC sessions would begin to

timeout. You can set the down-notify timer to a lower value, allowing OSPF

to sense that an interface is down quicker. This enables an alternate route

to be chosen more quickly, which will prevent the LLC sessions from timing

out.

Note: If the set down-notifycommand is executed on one end of a serial

 

link, the same command must be performed at the other end of the

 

link or the link may not come up and stay up.

 

Interface#

 

The number of the interface you are con®guring.

 

# of seconds

 

The down noti®cation time value that speci®es the maximum

 

time that will elapse before a down interface is marked as

 

such. Large values will cause the router to ignore transient

 

connection problems, and smaller values will cause the

 

router to react more quickly. The range of values is 1 to 300

 

seconds and the default is 0, which sets the 3-second

 

period. Setting the down noti®cation time to 0 will restore the

 

default time for that interface.

 

The list devices command will show the down noti®cation time

 

setting for any interface that has the default value overridden.

global-buffers max#

Sets the maximum number of global packet buffers, which are the packet

buffers used for locally originated packets. The default is to autocon®gure

for the maximum number of buffers (up to 1000). To restore the default, set

the value to 0. To display the setting for global-buffers, use the list

con®guration command.

hostname name

Adds or changes the router name. The router name is for identi®cation only;

it does not affect any router addresses. The name must be :
