Conﬁguring

Conﬁguration Alarm Dynamic

When the ATX learns a new address or ages (deletes) an old

address it may or may not send a trap based on the value of this

variable.

3.8 CONFIGURING NETBIOS NAME CACHING

The Netbios name caching function initially comes up disabled. To

enable or disable name caching, the ports to enable must be

provided. If you enable a port for Netbios Name Caching, you’ve

turned on the capability to learn the netbios names coming from

that port. If a port is disabled for caching, it will not prevent a

broadcast from going out that port. If a port is disabled for caching,

it will not prevent a broadcast from going out that port. If you have

netbios machines on two separate ports, both ports must be

enabled for Netbios cache for the functionality to work. To display

which ports are enabled or disabled for Netbios Name Caching,

simply type ‘nbcache’ without arguments or the ‘bridge’

command. To display the status of a speciﬁc port, type:

nbcache <port range> {on|off}

The nbentries command with no arguments will display the

current number of entries which can possibly be saved in the

cache. The number of entries can be modiﬁed by providing the

argument nbr_entries. Since memory is allocated at boot time, one

would need to reboot to get more/less space. The default value is

512, whereas the maximum number of entries is 5000.

nbentries [nbr_entries]

Note: Changing the number of entries directly affects the performance of

NetBIOS Name caching. Keeping the number of names to the

minimum amount necessary ensures peak performance for the

ATX.

The nbtimer command with no arguments displays the current
