This section describes the commands you use to configure Simple Network Management Protocol (SNMP) on the switch. You can configure the switch to act as an SNMP agent so that it can communicate with SNMP managers on your network
This command sets the name and the physical location of the switch, and the organization responsible for the network. The range for <name>, <loc> and <con> is from 1 to 31 alphanumeric characters.
This command adds (and names) a new SNMP community. A community <name> is a name associated with the switch and with a set of SNMP managers that manage it with a specified privileged level. The length of <name> can be up to 16 case-sensitive characters.
NOTE: Community names in the SNMP Community Table must be unique. When making multiple entries using the same community name, the first entry is kept and processed and all duplicate entries are ignored.
This command removes this community name from the table. The <name> is the community name to be deleted.
This command sets a client IP address for an SNMP community. The address is the associated community SNMP packet sending address and is used along with the client IP mask value to denote a range of IP addresses from which SNMP clients may use that community to access the device. A value of 0.0.0.0 allows access from any IP address. Otherwise, this value is ANDed with the mask to determine the range of allowed client IP addresses. The name is the applicable community name.
This command sets a client IP address for an SNMP community to 0.0.0.0. The name is the applicable community name.
This command sets a client IP mask for an SNMP community. The address is the associated community SNMP packet sending address and is used along with the client IP address value to denote a range of IP addresses from which SNMP clients may use that community to access the device. A value of 255.255.255.255 will allow access from only one station, and will use that machine's IP address for the client IP address. A value of 0.0.0.0 will allow access from any IP address. The name is the applicable community name.
This command sets a client IP mask for an SNMP community to 0.0.0.0. The name is the applicable community name. The community name may be up to 16 alphanumeric characters.
This command activates an SNMP community. If a community is enabled, an SNMP manager associated with this community manages the switch according to its access right. If the community is disabled, no SNMP requests using this community are accepted. In this case the SNMP manager associated with this community cannot manage the switch until the Status is changed back to Enable.
This command deactivates an SNMP community. If the community is disabled, no SNMP requests using this community are accepted. In this case the SNMP manager associated with this community cannot manage the switch until the Status is changed back to Enable.
This command restricts access to switch information. The access mode is read-only (also called public).
This command restricts access to switch information. The access mode is read/write (also called private).
This command enables the sending of new violation traps designating when a packet with a disallowed MAC address is received on a locked port.
This command disables the sending of new violation traps.
This command enables the Authentication Flag.
This command disables the Authentication Flag.
The bgp option on the "snmp-server enable traps" command above enables the two traps defined in the standard BGP MIB, RFC 4273. A trap is sent when an adjacency reaches the ESTABLISHED state and when a backward adjacency state transition occurs.
This command enables Link Up/Down traps for the entire switch. When enabled, link traps are sent only if the Link Trap flag setting associated with the port is enabled.
NOTE: This command may not be available on all platforms.
This command disables Link Up/Down traps for the entire switch.
This command enables Multiple User traps. When the traps are enabled, a Multiple User Trap is sent when a user logs in to the terminal interface (EIA 232 or Telnet) and there is an existing terminal interface session.
This command disables Multiple User traps.
This command enables the sending of new root traps and topology change notification traps.
This command disables the sending of new root traps and topology change notification traps.
This command adds an SNMP trap receiver. The maximum length of <name> is 16 case-sensitive alphanumeric characters. The value for ipaddr or ip6addr can be an IPv4 address, IPv6 address, or hostname. The <snmpversion> is the version of SNMP. The version parameter options are snmpv1 or snmpv2. The SNMP trap address can be set using both an IPv4 address format as well as an IPv6 global address format.
NOTE: The <name> parameter does not need to be unique, however; the <name> and <ipaddr> pair must be unique. Multiple entries can exist with the same <name>, as long as they are associated with a different <ipaddr>. The reverse scenario is also acceptable. The <name> is the community name used when sending the trap to the receiver, but the <name> is not directly associated with the SNMP Community Table.
This command deletes trap receivers for a community.
This command modifies the SNMP version of a trap. The maximum length of <name> is 16 case-sensitive alphanumeric characters. The <snmpversion> parameter options are snmpv1 or snmpv2.
NOTE: This command does not support a “no” form.
This command assigns an IP address to a specified community name. The maximum length of name is 16 case-sensitive alphanumeric characters.
NOTE: IP addresses in the SNMP trap receiver table must be unique. If you make multiple entries using the same IP address, the first entry is retained and processed. All duplicate entries are ignored.
This command activates or deactivates an SNMP trap. Enabled trap receivers are active (able to receive traps). Disabled trap receivers are inactive (not able to receive traps).
This command deactivates an SNMP trap. Disabled trap receivers are unable to receive traps.
This command enables link status traps by interface.
NOTE: This command is valid only when the Link Up/Down Flag is enabled.
This command disables link status traps by interface.
NOTE: This command is valid only when the Link Up/Down Flag is enabled.
This command enables link status traps for all interfaces.
NOTE: This command is valid only when the Link Up/Down Flag is enabled.
This command disables link status traps for all interfaces.
NOTE: This command is valid only when the Link Up/Down Flag is enabled.
This command displays SNMP community information. Six communities are supported. You can add, change, or delete communities. The switch does not have to be reset for changes to take effect. The SNMP agent of the switch complies with SNMP Versions 1, 2 or 3. For more information about the SNMP specification, see the SNMP RFCs. The SNMP agent sends traps through TCP/IP to an external SNMP manager based on the SNMP configuration (the trap receiver and other SNMP community parameters).
The display parameters for above command are:
This command displays SNMP trap receivers. Trap messages are sent across a network to an SNMP Network Manager. These messages alert the manager to events occurring within the switch or on the network. Six trap receivers are simultaneously supported.
The display parameters for above command are:
This command displays trap conditions. Configure which traps the switch should generate by enabling or disabling the trap condition. If a trap condition is enabled and the condition is detected, the SNMP agent on the switch sends the trap to all enabled trap receivers. You do not have to reset the switch to implement the changes. Cold and warm start traps are always generated and cannot be disabled.
The display parameters for above command are:
