Usage
Information
You save the configuration and reload the chassis for the changes to the epoch command
setting to take affect.
When using 10 SFMs in an ExaScale chassis, the 10.4 and 2.4 settings are both linerate.
Additionally, the 2.4 setting has a lower latency.
When using 9 SFMs in an ExaScale chassis, the 10.4 setting is linerate; the 2.4 setting reduces
throughput. Dell Force10 recommends using the 10.4 setting when the system has 9 SFMs.
Using 8 SFMs in an ExaScale chassis reduces throughput at any epoch setting.
exec-banner

Enable the display of a text string when the user enters the EXEC mode.
Syntax
exec-banner
To disable the banner on terminal lines, enter no exec-banner.
Defaults
Enabled on all lines (if configured, the banner appears).
2.4 Enter the keyword 2.4 to set the epoch to 2.4 micro-seconds and lower the latency.
This option is available on the E600i and E1200i E-Series ExaScale systems only.
3.2 Enter the keyword 3.2 to set the epoch to 3.2 micro-seconds and lower the latency.
This option is available on the E600/E600i and E1200/E1200i only. ExaScale does not
supports this setting with FTOS 8.3.1.0 and later.
10.4 Enter the keyword 10.4 to set the epoch to 10.4 micro-seconds.
This is the default setting and is available on the E300, E600/E600i, and E1200.
Version 8.3.1.0 Added 2.4 micro-seconds option. ExaScale supports only 10.4 microseconds
and 2.4 microseconds with FTOS 8.3.1.0 and later.
Version 8.1.1.2 Introduced on E-Series ExaScale E600i
Version 8.1.1.0 Introduced on E-Series ExaScale E1200i
Version 6.2.1.1 Support for E300 introduced (10.4 only)
Version 6.1.1.0 Values changed as described above
Note: The E300 supports only the 10.4 epoch setting. The E-Series TeraScale E600/
E600i and the E1200/E1200i systems support the 10.4 and the 3.2 epoch settings.
Note: For E-Series ExaScale, the 2.4 setting is supported on FTOS version 8.3.1.0
and later. The 10.4 setting is supported on all ExaScale FTOS versions. The 3.2
setting is only supported on FTOS versions 8.2.1.0 and earlier.
