LineSpeed autoARP type: ARPA, ARP Timeout 04:00:00To display the ports in a VLAN, send an snmpget request for the object dot1qStaticEgressPorts using the interface index as theinstance number, as shown for an S-Series.The following example shows viewing VLAN ports using SNMP with no ports assigned.> snmpget -v2c -c mycommunity 10.11.131.185 .1.3.6.1.2.1.17.7.1.4.3.1.2.1107787786SNMPv2-SMI::mib-2.17.7.1.4.3.1.2.1107787786 = Hex-STRING:00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 0000 00 00 00 00 00 00 00 00 00 00 00 00 00 00 0000 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00The 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 — 64 ports on thedevice. The last stack unit begins on the 66th bit.The first hex pair, 00 in the previous example, represents ports 1 to 7 in Stack Unit 1. The next pair to the right represents ports 8 to15. 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 atthe 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 asuntagged; the first hex pair changes from 00 to 04.The following example shows viewing VLAN ports using SNMP with ports assigned.[Dell Networking OS system output]R5(conf)#do show vlan id 10Codes: * - Default VLAN, G - GVRP VLANsQ: U - Untagged, T - Taggedx - Dot1x untagged, X - Dot1x taggedG - GVRP tagged, M - Vlan-stackNUM Status Description Q Ports10 Inactive U Te 1/2[Unix system output]> snmpget -v2c -c mycommunity 10.11.131.185 .1.3.6.1.2.1.17.7.1.4.3.1.2.1107787786SNMPv2-SMI::mib-2.17.7.1.4.3.1.2.1107787786 = Hex-STRING: 40 00 00 00 00 00 00 00 00 00 00The value 40 is in the first set of 7 hex pairs, indicating that these ports are in Stack Unit 1. 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 valueof 1, indicating that Port 1/2 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 portsare tagged or untagged.Add Tagged and Untagged Ports to a VLANThe value dot1qVlanStaticEgressPorts object is an array of all VLAN members.The dot1qVlanStaticUntaggedPorts object is an array of only untagged VLAN members.
