The first hex pair, 00 in the previous example, represents ports 1 to 7 in Stack Unit 0. The next pair to the
right represents ports 8 to 15. To resolve the hex pair into a representation of the individual ports, convert
the hex pair to binary. Consider the first hex pair 00, which resolves to 0000 0000 in binary:
• Each position in the 8-character string is for one port, starting with Port 1 at the left end of the string,
and ending with Port 8 at the right end. A 0 indicates that the port is not a member of the VLAN; a 1
indicates VLAN membership.
All hex pairs are 00, indicating that no ports are assigned to VLAN 10. In the following example, Port 0/2 is
added to VLAN 10 as untagged; the first hex pair changes from 00 to 04.

The value 40 is in the first set of 7 hex pairs, indicating that these ports are in Stack Unit 0. The hex value
40 is 0100 0000 in binary. As described, the left-most position in the string represents Port 1. The next
position from the left represents Port 2 and has a value of 1, indicating that Port 0/2 is in VLAN 10. The
remaining positions are 0, so those ports are not in the VLAN.
NOTE: The table contains none of the other information the command provides, such as port speed
or whether the ports are tagged or untagged.
Add Tagged and Untagged Ports to a VLAN
The value dot1qVlanStaticEgressPorts object is an array of all VLAN members.
The dot1qVlanStaticUntaggedPorts object is an array of only untagged VLAN members. All VLAN
members that are not in dot1qVlanStaticUntaggedPorts are tagged.
• To add a tagged port to a VLAN, write the port to the dot1qVlanStaticEgressPorts object.
• To add an untagged port to a VLAN, write the port to the dot1qVlanStaticEgressPorts and
dot1qVlanStaticUntaggedPorts objects.
NOTE: Whether adding a tagged or untagged port, specify values for both
dot1qVlanStaticEgressPorts and dot1qVlanStaticUntaggedPorts.
In the following example, Port 0/2 is added as an untagged member of VLAN 10.
