Troubleshooting Routers

1-2

Reading the Release Notes and Relevant Documentation

The release notes and the manuals that describe how to conﬁgure and manage the

protocols on your network provide guidelines on how to prevent problems. Read

them before installing or upgrading router or Site Manager software.

Minimizing Disruption When Installing New Software

When installing or upgrading software, or using a new feature for the ﬁrst time,

test it at a time or on a node that minimizes disruption to the network. After

verifying the change, make the change and verify it on one node at a time in the

network. Doing so will help you to isolate and solve any problems that may occur

as a result of the change.

Selecting the Proper Tool for Conﬁguring a Router

We recommend that you use the conﬁguration tools as follows:

• Use the Conﬁguration Manager in remote or local mode when you create a

new conﬁguration ﬁle or make major changes to an existing conﬁguration ﬁle.

• Use the Conﬁguration Manager in dynamic mode only to perform minor

changes such as change a ﬁlter or add a port.

• Use the Technician Interface to issue

set

and

commit

commands to make

minor conﬁguration changes only if the Site Manager is unavailable; the

Technician Interface does not provide error-checking.

Saving Your Conﬁguration Changes

The router overwrites the conﬁguration changes in memory when it reboots. If

you use either the Conﬁguration Manager in dynamic mode or the Technician

Interface

set

and

commit

commands to change the ﬁle in memory, you must

perform the following procedures if you want to save your changes.

Caution:

Dynamic changes to the router’s base records and global

parameters can cause an interruption in service. For example, if you change

the size of the bridge forwarding table, the router deletes the table and

re-creates it, causing a temporary decline in performance. Therefore, you may

want to schedule such changes to minimize their impact on your network.
