If you do not specify a permit list, both the SNMP and Telnet permit lists are enabled. Caution Before enabling the IP permit list, make sure that you add the IP address of your workstation or network management system to the permit list, especially when configuring through SNMP. Failure to do so could result in your connection being dropped by the switch that you are configuring. We recommend that you disable the IP permit list before clearing IP permit entries or host addresses. To enable the IP permit list on the switch, perform this task in privileged mode: Step 1 Step 2 Step 3 Step 4 Task Enable the IP permit list. If desired, enable the IP permit trap to generate traps for unauthorized access attempts. If desired, configure the logging level to see syslog messages for unauthorized access attempts. Verify the IP permit list configuration. Command set ip permit enable [ssh | snmp | telnet] set snmp trap enable ippermit set logging level ip 4 default show ip permit show snmp This example shows how to enable the IP permit list and verify the configuration: Console> (enable) set ip permit enable Telnet, Snmp and Ssh permit list enabled Console> (enable) set snmp trap enable ippermit SNMP IP Permit traps enabled.
