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 line rate. Additionally,
the 2.4 setting has a lower latency.
When using 9 SFMs in an ExaScale chassis, the 10.4 setting is line rate; 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.
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.
