parameters:

default setting is 0 (low priority).
4. Select the VLAN Type. The choices for VLAN Ethernet type are 8100,
88A8, 9100, 9200, and 9300. The default setting is 8100 for VLAN #1
and 88A8 for VLAN #2.
5. The Drop Eligible parameter allows the Service VLAN tag (S-TAG) to
convey eight distinct priorities, each with a drop eligible indication.
When enabled (DEI = 1), the drop eligible parameter is encoded in the
DEI of transmitted frames. The drop eligible parameter should be
enabled for a received frame if the DEI is set in the S-TAG or if the
Priority Code Point Decoding Table indicates drop eligible enabled for
the received PCP value. When disabled (DEI=0), the DEI is ignored on
receipt. Drop Eligible is not available when VLAN type is 8100. This
setting is disabled by default.
