Configuring SNMP Chapter 6 Configuring the System 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. Table 6-5 Catalyst 1900 and Catalyst 2820 SNMP Traps Trap Type Description Address-violation Generates a trap when the address violation threshold is exceeded. Authentication Generates a trap when an SNMP request is not accompanied by a valid community string. BSC Generates a trap when the broadcast threshold is exceeded. Link-up-down Generates a link-down trap when a port is suspended or disabled for any of these reasons: • Secure address violation (address mismatch or duplication) • Network connection error (loss of linkbeat or jabber error) • User disabling the port Generates a link-up trap when a port is enabled for any of these reasons: • Presence of linkbeat • Management intervention • Recovery from an address violation or any other error • STP action VTP Generates a trap when VTP changes occur. Beginning in privileged EXEC mode, follow these steps to add a trap manager and a community string: Step 1 Step 2 Step 3 Step 4 Command config terminal snmp-server host 172.2.128.263 community-string snmp vlan-membership end show running-config Purpose Enter global configuration mode. Enter the trap manager IP address, the community string, and the traps to generate. Return to privileged EXEC mode. Verify that the information was entered correctly by displaying the running configuration. 6-50 Catalyst 2900 Series XL and Catalyst 3500 Series XL Software Configuration Guide 78-6511-08
