Table 134. SNMP Traps and OIDs
OID String OID Name Description
Receiving Power
.1.3.6.1.4.1.6027.3.10.1.2.5.1.6 chSysPortXfpRecvPower OID displays the receiving power of the
connected optics.
Transmitting power
.1.3.6.1.4.1.6027.3.10.1.2.5.1.8 chSysPortXfpTxPower OID displays the transmitting power of
the connected optics.
Temperature
.1.3.6.1.4.1.6027.3.10.1.2.5.1.7 chSysPortXfpRecvTemp OID displays the temperature of the
connected optics.
NOTE: These OIDs only generate
if you enable the enable
optic-info-update-interval
is enabled command.

per COS per port.
Buffer Tuning
Buffer Tuning allows you to modify the way your switch allocates buffers from its available memory and helps prevent packet
drops during a temporary burst of traffic.
Using a PreDefined Buffer Profile
Dell EMC Networking OS provides two predefined buffer profiles, one for single-queue (for example, non-quality-of-service
[QoS]) applications, and one for four-queue (for example, QoS) applications.
You must reload the system for the global buffer profile to take effect, a message similar to the following displays: % Info:
For the global pre-defined buffer profile to take effect, please save the config and reload
the system..
Dell EMC Networking OS Behavior: After you configure buffer-profile global 1Q, the message displays during every bootup.
Only one reboot is required for the configuration to take effect; afterward you may ignore this bootup message.
Dell EMC Networking OS Behavior: If you configure 1Q, save the running-config to the startup-config, and then delete
the startup-config and reload the chassis. The only way to return to the default buffer profile is to remove the 1Q profile
configured and then reload the chassis.
If you have already applied a custom buffer profile on an interface, the buffer-profile global command fails and a
message similar to the following displays: % Error: User-defined buffer profile already applied. Failed
to apply global pre-defined buffer profile. Please remove all user-defined buffer profiles.
Similarly, when you configure buffer-profile global, you cannot not apply a buffer profile on any single interface. A
message similar to the following displays: % Error: Global pre-defined buffer profile already applied.
Failed to apply user-defined buffer profile on interface Te 1/1. Please remove global pre-
defined buffer profile.
To apply a predefined buffer profile, use the following command:
