SLX-OS supports SNMP version 1, version 2c, and version 3. Use the commands listed in the following table to configure the SNMPv1, SNMPv2c, and SNMPv3 hosts and their configurations.
| Command | Description |
|---|---|
|
[no] snmp-server host {ipv4-host | ipv6-host | dns-host} community-string [severity-level [none | debug | info | warning | error | critical] [udp-port port_number] [version [1 | 2c] |
This command sets the destination IP addresses, version, community string (for version 1 and version 2c), and destination port for the traps. The severity-level option is used to filter the traps based on severity. The no form of the command changes the SNMP server host configurations to the default value. |
|
[no] snmp-server v3host {ipv4-host | ipv6-host | dns-host} username [notifytype {traps | informs}] engineid engine-id severity-level [none | debug | info | warning | error | critical] udp-port port_number |
This command specifies the recipient of the SNMP version 3 notification option. The severity-level option is used to filter the traps or informs based on severity. Use the no form of the command to remove a specific host. |
To set the trap destination IP addresses, version (1 or 2c), community string for SNMP version 1 and version 2c, and the destination port for the SNMP traps, perform the following steps.
Enter the configure terminal command to access the global configuration level of the CLI.
device# configure terminal Entering configuration mode terminal
Enter the following command to set the trap recipient with IP address 192.0.2.2, which receives all traps with the severity levels of Critical, Error, Info, and Warning.
device(config)# snmp-server host 192.0.2.2 public severity-level Info udp-port 162 version 1
Note
To receive the traps, the management station IP address must be configured on the switch.device(config)# do show running-config snmp-server snmp-server sys-descr "Extreme SLX9740-80C Switch/Router" snmp-server engineID local 80:0:6:34:b2:7e:88:0:10:a:14:d3:25 snmp-server community $9$5NQFNEVN67kKklzWw+b/rg== groupname group2 snmp-server community $9$dlGJTAP4O2fz40uz+6p24g== groupname group1 snmp-server community $9$ZqrZyV4ln8u5MqJeUGHblg== groupname group3 snmp-server host 10.20.192.72 $9$5NQFNEVN67kKklzWw+b/rg== version 2c severity-level Info ! snmp-server host 10.20.192.72 $9$dlGJTAP4O2fz40uz+6p24g== severity-level Info ! snmp-server user snmpteam1 groupname group3 auth sha auth-password nHW0ev6kLY priv AES128 priv-password nHW0ev6kLY encrypted snmp-server user snmpteam3 groupname group3 auth md5 auth-password XoooIwNn47 priv AES128 priv-password XoooIwNn47 encrypted snmp-server user snmpteam4 groupname grpauth_nopriv auth sha auth-password nHW0ev6kLY encrypted snmp-server user user groupname group3 auth md5 auth-password XoooIwNn47 priv AES128 priv-password XoooIwNn47 encrypted snmp-server v3host 10.20.192.72 snmpteam1 severity-level Info ! snmp-server view all 1 included snmp-server view All 1 included snmp-server group group1 v1 read all write all notify all snmp-server group group2 v2c read all write all notify all snmp-server group group3 v3 priv read all write all notify all snmp-server group grpauth_nopriv v3 auth read All write All notify All dutA(config)# do show running-config snmp-server snmp-server sys-descr "Extreme SLX9740-80C Switch/Router" snmp-server engineID local 80:0:6:34:b2:7e:88:0:10:a:14:d3:25 snmp-server community $9$5NQFNEVN67kKklzWw+b== groupname group2 snmp-server community $9$dlGJTAP4O2fz40uz+6p== groupname group1 snmp-server community $9$ZqrZyV4ln8u5MqJeUGH== groupname group3 snmp-server host 10.20.192.72 $9$5NQFNEVN67kKklzWw+b== version 2c severity-level Info ! snmp-server host 10.20.192.72 $9$dlGJTAP4O2fz40uz+6p== severity-level Info ! snmp-server user snmpteam1 groupname group3 auth sha auth-password nHW0ev6kLY priv AES128 priv-password nHW0ev6kLY encrypted snmp-server user snmpteam3 groupname group3 auth md5 auth-password XoooIwNn47 priv AES128 priv-password XoooIwNn47 encrypted snmp-server user snmpteam4 groupname grpauth_nopriv auth sha auth-password nHW0ev6kLY encrypted snmp-server user user groupname group3 auth md5 auth-password XoooIwNn47 priv AES128 priv-password XoooIwNn47 encrypted snmp-server v3host 10.20.192.72 snmpteam1 severity-level Info ! snmp-server view all 1 included snmp-server view All 1 included snmp-server group group1 v1 read all write all notify all snmp-server group group2 v2c read all write all notify all snmp-server group group3 v3 priv read all write all notify all snmp-server group grpauth_nopriv v3 auth read All write All notify All device(config)#
Use the snmp-server v3-host command to specify the recipient of SNMP version 3 notifications: traps or informs. The following example describes the procedure for configuring the recipient of the SNMPv3 informs.
device# configure terminal Entering configuration mode terminal
Enter the following command to set the inform recipient with IP address 192.0.2.2, which receives all traps with the severity levels of Critical, Error, Info, and Warning.
device(config)# snmp-server v3host 192.0.2.2 snmpadmin1 notifytype informs engineid 80:00:05:23:01:AC:1A:01:79 severity-level Info udp-port 4425
Note
To receive the SNMP informs, the username, authentication protocol, privacy protocol, UDP port number, and engine ID must match between the switch and management station.
