OID String OID Name Description
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.

Buer Tuning
Buer Tuning allows you to modify the way your switch allocates buers from its available memory and helps prevent packet drops during a
temporary burst of trac.
Using a PreDened Buer Prole
Dell EMC Networking OS provides two predened buer proles, 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 buer prole to take eect, 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 congure buer-prole global 1Q, the message displays during every bootup. Only one
reboot is required for the conguration to take eect; afterward you may ignore this bootup message.
Dell EMC Networking OS Behavior: If you congure 1Q, save the running-cong to the startup-config, and then delete the
startup-config and reload the chassis. The only way to return to the default buer prole is to remove the 1Q prole congured and
then reload the chassis.
If you have already applied a custom buer prole 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 congure buffer-profile global, you cannot not apply a buer prole 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 predened buer prole, use the following command:
