snmp-server host

Configure the recipient of an SNMP trap operation.

Syntax snmp-server host ip-address [traps | informs] [version 1 | 2c | 3] [auth | no auth | priv] [ community-string] [udp-port port-number] [ notification-type]

To remove the SNMP host, use the no snmp-server host ip-address [traps | informs] [version 1 | 2c | 3] [auth | noauth | priv] [ community-string] [udp-port number] [ notification-type] command.

Parameters
ip-address Enter the keyword host then the IP address of the host (configurable hosts is limited to 16).
traps (OPTIONAL) Enter the keyword traps to send trap notifications to the specified host. The default is traps.
informs (OPTIONAL) Enter the keyword informs to send inform notifications to the specified host. The default is traps.
version 1 | 2c | 3 (OPTIONAL) Enter the keyword version to specify the security model then the security model version number 1, 2c, or 3:
  • Version 1 is the least secure version.
  • Version 3 is the most secure of the security modes.
  • Version 2c allows transmission of informs and counter 64, which allows for integers twice the width of what is normally allowed.

The default is version 1.

auth (OPTIONAL) Enter the keyword auth to specify authentication of a packet without encryption.
noauth (OPTIONAL) Enter the keyword noauth to specify no authentication of a packet.
priv (OPTIONAL) Enter the keyword priv to specify both authentication and then scrambling of the packet.
community-string Enter a text string (up to 20 characters long) as the name of the SNMP community.
  • NOTE: For version 1 and version 2c security models, this string represents the name of the SNMP community. The string can be set using this command; however, Dell Networking OS recommends setting the community string using the snmp-server community command before executing this command. For version 3 security model, this string is the USM user security name.
udp-port port-number (OPTIONAL) Enter the keywords udp-port then the port number of the remote host to use. The range is from 0 to 65535. The default is 162.
notification-type (OPTIONAL) Enter one of the following keywords for the type of trap to send to the host:
  • ecfm — Notification of ECFM state changes.
  • entity — Notification of entity changes.
  • envmon — Environment monitor trap.
  • eoam — Notificaiton of EOAM state changes.
  • ets — Notification of ets trap changes.
  • fips — Notification of FIP snooping state changes.
  • lacp — Notificaiton of LACP state changes.
  • snmp — SNMP notification (RFC 1157).
  • stp — Spanning tree protocol notification (RFC 1493).
  • vrrp — State change in a VRRP group.
  • xstp — State change in MSTP (802.1s), RSTP (802.1w), and PVST+.

The default is all trap types are sent to host.

Usage Information

In order to configure the router to send SNMP notifications, enter at least one snmp-server host command. If you enter the command with no keywords, all trap types are enabled for the host. If you do not enter an snmp-server host command, no notifications are sent.

In order to enable multiple hosts, issue a separate snmp-server host command for each host. You can specify multiple notification types in the command for each host.

When multiple snmp-server host commands are given for the same host and type of notification (trap or inform), each succeeding command overwrites the previous command. Only the last snmp-server host command is in effect. For example, if you enter an snmp-server host inform command for a host and then enter another snmp-server host inform command for the same host, the second command replaces the first command.

The snmp-server host command is used with the snmp-server enable command. Use the snmp-server enable command to specify which SNMP notifications are sent globally. For a host to receive most notifications, at least one snmp-server enable command and the snmp-server host command for that host must be enabled.

  • NOTE: For v1 / v2c trap configuration, if the community-string is not defined using the snmp-server community command prior to using this command, the default form of the snmp-server community command automatically is configured with the community-name the same as specified in the snmp-server host command.

Configuring Informs

To send an inform, use the following steps:
  1. Configure a remote engine ID.
  2. Configure a remote user.
  3. Configure a group for this user with access rights.
  4. Enable traps.
  5. Configure a host to receive informs.
