Chapter 6 Configuring the System

Configuring SNMP

Catalyst 1900 and Catalyst 2820 switches support up to four trap managers. When you configure

community strings for these switches, limit the string length to 32 characters. When configuring traps

on these switches, you cannot configure individual trap managers to receive specific traps.

Table 6-5 describes the Catalyst 1900 and Catalyst 2820 SNMP traps. You can enable any or all of these

traps, but these traps are received by all configured trap managers.

Beginning in privileged EXEC mode, follow these steps to add a trap manager and a community string:
