VLAN Configuration
VLAN Configuration page allows the user to configure the layers, its priority,
type, and drop eligible.
Press , select Traffic Generation & Monitoring, Background Stream

To configure VLAN settings:
1. Select the Background Stream
for which VLAN parameters are to
be configured.
2. Select the number of VLAN layers
for which VLAN parameters are to
be configured. Choices are None,
1 Layer, and 2 Layers.
3. Enter the VLAN ID. The accepted
range is from 0 to 4095. The
default value is 2. See VLAN on page 242.
4. Select the VLAN Priority. The accepted range is from 0 to 7. The
default value is 0 (Low priority). See VLAN on page 242.
5. Select the VLAN Type. Choices for VLAN Ethernet type are 8100, 88A8,
9100, 9200, and 9300. The default value is 8100 for VLAN 1 and 88A8
for VLAN 2.
6. 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.
