3.2.1 Configuring the Host
Configure parameters of the NMS host and packet handling mechanism.
Step 1 configure
Enter global configuration mode.
Step 2 snmp-server host
ip udp-port user-name
[smode { v1 | v2c | v3 }] [slev {noAuthNoPriv |
authNoPriv | authPriv }] [type { trap | inform}] [retries
retries
] [timeout
timeout
]
Configure parameters of the NMS host and packet handling mechanism.
ip:
Specify the IP address of the NMS Host in IPv4 or IPv6. Please make sure the IP
addresses of the Host and the switch are able to reach to each other.
udp-port:
Specify a UDP port on the host to send notifications. The default is port 162.
For communication security, we recommend that you change the port number under the
condition that communications on other UDP ports are not affected.
user-name:
Enter the name used by the NMS. When the NMS uses SNMPv1 or SNMPv2c,
enter the Community Name; when the NMS uses SNMPv3, enter the User Name of the
SNMP Group.
v1 | v2c | v3 :
Choose a security mode for the SNMP group from the following: SNMPv1,
SNMPv2c, SNMPv3.
noAuthNoPriv | authNoPriv | authPriv:
For SNMPv3 groups, choose a security level from
noAuthNoPriv (no authorization and no encryption), authNoPriv (authorization and no
encryption), authPriv (authorization and encryption). The defaut is noAuthNoPriv. Please
note that if you have chosen v1 or v2c as the security mode, security level cannot be
configured.
trap | inform:
Choose the information type which is only for SNMPv2c or SNMPv3; the
default is trap. When the NMS receives a trap message, it will not send a response to the
switch. Thus the switch cannot determine whether the trap is received or not, and the trap
that is not received will not be resent. When the NMS receives an Inform message, it will
send a response to the switch. If the switch does not receive a response within the Timeout
interval, it will resend the Inform message. Therefore, Informs are more reliable than Traps.
retries :
Set the retry times for Inform messages. The range is 1 to 255 and the default is 3.
The switch will resend the Inform message if it does not receive response from the NMS
within the timeout interval. And it will stop sending Inform message when the retry times
reaches the limit.
timeout :
Set the length of time that the switch waits for a response. The range is 1 to 3600
seconds; the default is 100 seconds. The switch will resend the Inform message if it does
not receive a response from the NMS within the timeout interval.
Step 3 show snmp-server host
Displays the information of the host.
Step 4 end
Return to privileged EXEC mode.
