SNMP Trap not Received

Perform the following procedure to troubleshoot issues in which an SNMP trap is not received.

Procedure

  1. Enter Global Configuration mode:

    enable

    configure terminal

  2. Show the BPDU Guard status for the port:

    show spanning-tree bpduguard {slot/port[/sub-port][-slot/port[/sub-port]][,...]}

  3. Configure the correct SNMP target information:

    snmp-server host WORD<1-256> [port <1-65535>] v3 {noAuthNoPriv|authNoPriv|authPriv WORD<1-32> [inform [timeout <1-2147483647>][retries <0-255>]] [filter WORD<1-32>]

Example

In the following example, BPDU guard is enabled on port 1/8, BPDU packets are received, port 1/8 is disabled, and the TimerCount is incrementing, but no SNMP trap is ever received.

Switch:1>enable
Switch:1#show spanning-tree bpduguard 1/8

Variable Definitions

The following table defines parameters for the show spanning-tree command.

Variable

Value

{slot/port[/sub-port][-slot/port[/sub-port]][,...]}

Identifies the slot and port in one of the following formats: a single slot and port (slot/port), a range of slots and ports (slot/port-slot/port), or a series of slots and ports (slot/port,slot/port,slot/port). If the platform supports channelization and the port is channelized, you must also specify the sub-port in the format slot/port/sub-port.

The following table defines parameters for the snmp-server host command.

Variable

Value

filter WORD<1-32>

Specifies a filter profile name.

host WORD<1-256>

Specifies the IPv4 or IPv6 host address

inform [timeout <1-2147483647>]

Specifies the notify type. The optional timeout parameter configures the timeout value, which specifies the time to wait for a reply before resending the inform message. Time is specified in centiseconds

noAuthNoPriv|authNoPriv|authPriv WORD<1-32>

Specifies the security level.

port <1-65535>

Specifies the port number that will be set as the destination port at the UDP level in the trap packet.

retries <0-255>

Specifies the number of packets to be sent if no reply is received.

{slot/port[/sub-port][-slot/port[/sub-port]][,...]}

Identifies the slot and port in one of the following formats: a single slot and port (slot/port), a range of slots and ports (slot/port-slot/port), or a series of slots and ports (slot/port,slot/port,slot/port). If the platform supports channelization and the port is channelized, you must also specify the sub-port in the format slot/port/sub-port.
