Configure SNMP settings

Configure Simple Network Management Protocol (SNMP) to define or modify the SNMP settings, and specify the security level for SNMP communications.

Procedure

  1. Enter Global Configuration mode:

    enable

    configure terminal

  2. Enable the generation of authentication traps:

    snmp-server authentication-trap enable

  3. Configure the contact information for the system:

    snmp-server contact WORD<0-255>

  4. Create an SNMPv1 server host:

    snmp-server host WORD<1-256> [port <1-65535>] v1 WORD<1-32> [filter WORD<1-32>]

  5. Create an SNMPv2 server host:

    snmp-server host WORD<1-256> [port <1-65535>] v2c WORD<1-32> [inform] [timeout <1-2147483647>][retries <0-255>][mms <0-2147483647>]] [filter WORD<1-32>]

  6. Create an SNMPv3 server host:

    snmp-server host WORD<1-256> [port <1-65535>] v3 {noAuthNoPriv|authNoPriv|authPriv WORD<1-32> [inform] [timeout <1-2147483647>][retries <0-255>]] [filter WORD<1-32>]

  7. Configure the system location:

    snmp-server location WORD<0-255>

  8. Enable login-success traps:

    snmp-server login-success-trap enable

  9. Configure the system name:

    snmp-server name WORD<0-255>

  10. Create a new entry in the notify filter table:

    snmp-server notify-filter WORD<1-32> WORD<1-32>

Example

Enable the generation of SNMP traps. Configure the contact information for the system. Configure hosts to receive SNMP notifications:

Switch:1>enable
Switch:1#configure terminal
Switch:1(config)#snmp-server authentication-trap enable
Switch:1(config)#snmp-server contact xxxx@company.com
Switch:1(config)#snmp-server host 192.0.2.16 port 1 v1 SNMPv1 filter SNMPfilterv1

Variable Definitions

The following table defines parameters for the snmp-server command.

Variable

Value

authentication-trap {enable}

Enables generation of SNMP server authentication traps.

contact WORD<0-255>

Changes the sysContact information for the switch. WORD<0-255> is an ASCII string from 0–255 characters (for example, a phone extension or email address).

host WORD<1-256> [port <1-65535>] {v1 WORD<1-32>|v2c WORD<1-32> [inform] [timeout <1-2147483647>][retries <0-255>][mms <0-2147483647>]]|v3 {noAuthPriv|authNoPriv|authPriv} WORD<1-32> [inform [timeout <1-2147483647>][retries <0-255>]]} [filter WORD<1-32>]
Configures hosts to receive SNMP notifications.

  • host WORD<1-256> specifies the IPv4 or IPv6 host address

  • port <1-65535> specifies the port number

  • v1 WORD<1-32> specifies the SNMPv1 security name

  • v2c WORD<1-32> specifies the SNMPv2 security name

  • inform specifies the notify type

  • timeout <1-2147483647> specifies the timeout value

  • retries <0-255> specifies the number of retries

  • mms < 1-2147483647> specifies the maximum message size

  • v3 specifies SNMPv3

  • noAuthPriv|authNoPriv|authPriv specifies the security level

  • WORD<1-32> specifies the user name

  • filter specifies a filter profile name

location WORD<0-255>

Configures the sysLocation information for the system. <WORD 0-255> is an ASCII string from 0–255 characters.

login-success-trap {enable}

Enables generation of SNMP server login-success traps.

name WORD<0-255>

Configures the sysName information for the system. <WORD 0-255> is an ASCII string from 0–255 characters.

notify-filter WORD<1-32> WORD<1-32>

Creates a new entry in the notify filter table. The first WORD<1-32> specifies the filter profile name, and the second WORD<1-32> specifies the subtree object identifier (OID).
