The Element Manager uses the default SNMP read/write community strings

as listed in the following table to discover devices. Because the SMB

devices and the Element Manager are using the same values, discovery

occurs upon network deployment.

If you change the simple network management protocol (SNMP) read/write

community strings, make the corresponding changes to the Element

Manager.

A Web user interface session times out after the designated value of time

passes. For the BSR222, this value is 5 minutes. For the BES and the

BAP120 devices, the timeout value is 1 minute. You can change these

timeout values through the Web user interface for each device.

Securing your SMB network

The SMB factory security defaults described in "Key factory security

defaults" (page 61) allow for ease of installation and efﬁcient network

deployment.

Nortel recommends that you change the factory default user IDs and that

you change passwords frequently using strong password methodology.

If you have a security policy in place that prevents the use of network

management protocols such as SNMP, follow the guidelines in this section

to establish your network without SNMP.
