Syslog Warning Upon Connecting SFP28 Optics
with QSA
When you connect the SFP28 optics with the QSA, the system displays the following syslog warning:
For Dell-qualified SFP28 optics:
Aug 5 01:14:55 %S6100-ON:1 %IFAGT-5-INSERT_OPTICS_SFP28: Optics SFP28 inserted in stack-unit
1 module 2 port 2/1. Wrong QSA in use. Please utilize QSA28, not lower speed QSA to guarantee
support and performance for 25G Optics and cables
For non Dell-qualified SFP28 optics:
Aug 8 20:31:56 % S6100-ON:1 %IFAGT-5-UNSUP_OPTICS: Non-qualified optics in stack-unit 1
module 2 port 2/1. Wrong QSA in use. Please utilize QSA28, not lower speed QSA to guarantee

Adjusting the Keepalive Timer
To change the time interval between keepalive messages on the interfaces, use the keepalive command. The interface sends keepalive
messages to itself to test network connectivity on the interface.
To change the default time interval between keepalive messages, use the following command.
Change the default interval between keepalive messages.

The following options have been implemented for the show [ip | running-config] interfaces commands for (only) stack-
unit interfaces.
When you use the configured keyword, only interfaces that have non-default configurations are displayed. Dummy stack-unit
interfaces (created with the stack-unit command) are treated like any other physical interface.
