Commands for Managing the Switch
enable snmp traps exceed-committed-rate ports
enable snmp traps exceed-committed-rate ports <portlist> {<Ingress QOS
Profile>}
Description
Enables SNMP traps for the condition when ingress traffic has exceeded the configured committed-rate
and is either being dropped, or is in danger of being dropped, on the indicated ports.
Syntax Description
Default
Disabled.
Usage Guidelines
This trap type was added to detect when ingress traffic exceeds the configured committed rate (CIR) or
is dropped due to exceeding the configured Peak Rate (PR) or oversubscription. These conditions
should also be evident via the
show port x:y ingress stats detail
command from the console.
When either the Exceeds-CIR or Dropped-Bytes condition changes state, an SNMP trap will be sent to
all registered trap receivers. Committed and peak rate violations will be written to the syslog when this
trap is enabled. The trap that is sent to the SNMP application will consist of:
Trap Type (1=Exceeded CIR, 2=Dropped Bytes)
Status (1=event occurred, 0=event condition cleared)
Port
Queue
Byte count (valid only for Status=0 to show the Exceeded/Dropped byte count)
This command affects ports on “3” series I/O Ethernet modules only, and is configurable per port (all
queues) or per queue on specified ports. By default, this trap type is disabled for all queues on all ports.
This trap type applies only to “3” series I/O-based ingress rate-limiting and ingress oversubscription,
and not to “3” series I/O-based egress rate-limiting.
To see which ports have such traps enabled, use the
show config
command.
Example
The following command will enable exceed-committed-rate traps for all ingress QOS profiles on ports
2:5 through 2:8.
enable snmp traps exceed-committed-rate ports 2:5-2:8
portlist Specifies a list of
“3”
series I/O ports (in the form 2:*, 2:5, or 2:6-2:8), for
which the specified trap will apply.
Ingress QOS Profile Specifies an optional ingress QOS profile. If not specified, all ingress QOS
profiles for the indicated ports will be affected.
