To display the ports in a VLAN, send an snmpget request for the object dot1qStaticEgressPorts using the
interface index as the instance number, as shown in the following example.

The table that the Dell Networking system sends in response to the snmpget request is a table that
contains hexadecimal (hex) pairs, each pair representing a group of eight ports.
• Seven hex pairs represent a stack unit. Seven pairs accommodate the greatest number of ports
available on an Aggregator, 56 ports. The last stack unit is assigned eight pairs, the eight pair is
unused.
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.
