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 for an S-Series in Figure 38-18. Figure 38-18. Display the Ports in a VLAN in SNMP > snmpget -v2c -c mycommunity 10.11.131.185 .1.3.6.1.2.1.17.7.1.4.3.1.2.1107787786 SNMPv2-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 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 The table that the Dell Force10 system sends in response to the snmpget request is a table that contains hexadecimal (hex) pairs, each pair representing a group of eight ports. • On the E-Series, 12 hex pairs represents a line card. Twelve pairs accommodates the greatest currently available line card port density, 96 ports. • On the C-Series, 28 hex pairs represents a line card. Twenty-eight pairs accommodates the greatest currently available line card port density, 28 ports per port-pipe, and any remaining hex pairs are unused. • On the S-Series, 7 hex pairs represents a stack unit. Seven pairs accommodates the greatest number of ports available on an S-Series, 56 ports. The last stack unit is assigned 8 pairs; the eighth pair is unused. The first hex pair, 00 in Figure 38-18, represents ports 1-7 in Stack Unit 0. The next pair to the right represents ports 8-15. 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: • On the E-Series and C-Series each position in the 8-character string is for one port, starting with Port 0 at the left end of the string, and ending with Port 7 at the right end. A 0 indicates that the port is not a member of the VLAN; a 1 indicates VLAN membership. • On the S-Series, 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. Figure 38-18 shows the output for an S-Series. All hex pairs are 00, indicating that no ports are assigned to VLAN 10. In Figure 38-19, Port 0/2 is added to VLAN 10 as untagged. And the first hex pair changes from 00 to 04.
