Authentication Failure Traps
The router generates an authentication failure trap when it receives an SNMP
message from an SNMP manager falsely claiming to be in a particular community
or specifying an unknown community.
To enable the authentication failure trap feature on the router, configure an SNMP
community manager to receive the trap. (See Configuring SNMP, BootP, DHCP,
and RARP Services.)
Assigning SecurID to Telnet Connections
You can enable password protection for your Telnet connections to the router
using SecurID services. See Using Technician Interface Software for information
about enabling SecurID services.
Turning Off FTP and Telnet on the Router
If you have local access to your router or do not need network access to maintain
your router, consider turning off FTP and Telnet. Your router will be more secure
without network access and will require less memory and processing overhead.
You can turn these services off using the BCC or Site Manager. See Configuring
IP Utilities for instructions.
Using the Image Builder to Remove Services
The Image Builder tool provided with Site Manager allows you to modify the
router software image. You can use the Image Builder tool to remove unwanted
services and protocols, such as FTP, from the router. See Configuring and
Managing Routers with Site Manager for more information.
