CN4093 Application Guide for N/OS 8.2
Each priority group may be configured from its corresponding ETS Priority Group,
available using the following command:
CN4093(config)# cee global ets priority­group pgid <group number (0‐7, or 15)>
priority <priority list>
where priority list is one or more 802.1p priority values (with each separated by a
comma). For example, to assign priority values 0 through 2:
CN4093(config)# cee global ets priority­group pgid <group number (0‐7, or 15)>
priority 0,1,2
Note: Within any specific PGID, the PFC settings (see
Control" on page 274) should be the same (enabled or disabled) for all priority
values within the group. PFC can be enabled only on priority value 3 and one other
priority. If the PFC setting is inconsistent within a PGID, a warning message is
reported when attempting to apply the configuration.
When assigning priority values to a PGID, the specified priority value will be
automatically removed from its old group and assigned to the new group when
the configuration is applied.
Each priority value must be assigned to a PGID. Priority values may not be deleted
or unassigned. To remove a priority value from a PGID, it must be moved to
another PGID.
For PGIDs 0 through 7, bandwidth allocation can also be configured through the
ETS Priority Group menu. See for "Allocating Bandwidth" on page
A priority group is automatically deleted when it contains no associated priority
values, and its bandwidth allocation is set to 0%.
Note: The total bandwidth allocated to PGID 0 through 7 must equal exactly 100%.
Reducing the bandwidth allocation of any group will require increasing the
allocation to one or more of the other groups (see
page 281).
