Basic Switch Configuration
Command Explanation
Global Mode
snmp-server host { <host-ipv4-address> |
<host-ipv6-address> } { v1 | v2c | { v3 {
noauthnopriv | authnopriv | authpriv } } }
<user-string>
no snmp-server host { <host-ipv4-address>
| <host-ipv6-address> } {v1 | v2c | { v3 {
noauthnopriv | authnopriv | authpriv } } }

Set the host IPv4/IPv6 address which is used
to receive SNMP Trap information. For SNMP
v1/v2, this command also configures Trap com-
munity string; for SNMP v3, this command also
configures Trap user name and security level.
The no form of this command cancels this IPv4
or IPv6 address.
snmp-server trap-source { <ipv4-address> |
<ipv6-address> }
no snmp-server trap-source { <ipv4-
address> | <ipv6-address> }
Set the source IPv4 or IPv6 address which is
used to send trap packet, the no command
deletes the configuration.

2.4.5 Typical SNMP Configuration Examples
The IP address of the NMS is 1.1.1.5; the IP address of the switch (Agent) is 1.1.1.9.
Scenario 1: The NMS network administrative software uses SNMP protocol to obtain data
from the switch.
The configuration on the switch is listed below:
Switch(config)#snmp-server enable
Switch(config)#snmp-server community rw private
Switch(config)#snmp-server community ro public
Switch(config)#snmp-server securityip 1.1.1.5
The NMS can use private as the community string to access the switch with read-write permis-
sion, or use public as the community string to access the switch with read-only permission.
Scenario 2: NMS will receive Trap messages from the switch (Note: NMS may have commu-
nity string verification for the Trap messages. In this scenario, the NMS uses a Trap verification
community string of usertrap).
The configuration on the switch is listed below:
Switch(config)#snmp-server enable
Switch(config)#snmp-server host 1.1.1.5 v1 usertrap
Switch(config)#snmp-server enable traps
Scenario 3: NMS uses SNMP v3 to obtain information from the switch.
The configuration on the switch is listed below:
