Dell C1048P Port Extender Networking Command-Line Reference Guide for the C900 - Page 1915

Version 8.3.7.0 8.2.1.0 7.8.1.0 7.7.1.0 7.6.1.0 Description Introduced on the S4810. Introduced on the E-Series ExaScale. C-Series and S-Series accept both bytes of the 2-byte S-Tag TPID. Functionality augmented for C-Series and S-Series to enable multi-purpose use of the port. Functionality augmented for E-Series to enable multi-purpose use of the port. Introduced on the C-Series and S-Series. Usage Information Prior to using this command, to place the interface in Layer 2 mode, execute the switchport command. To remove the trunk port designation, first remove the port (using the no member interface command) from all stackable VLAN-enabled VLANs. A VLAN-Stack trunk port is also allowed to be configured as a tagged port and as an untagged port for single-tagged VLANs. When the VLAN-Stack trunk port is also a member of an untagged VLAN, the port must be in Hybrid mode. Refer to portmode hybrid. In Example 1, a VLAN-Stack trunk port is configured and then also made part of a single-tagged VLAN. In Example 2, the tag protocol identifier (TPID) is set to 8848. The "Te 2/10" port is configured to act as a VLAN-Stack access port, while the "Te 1/0" port acts as a VLAN-Stack trunk port, switching stackable VLAN traffic for VLAN 10, while also switching untagged traffic for VLAN 30 and tagged traffic for VLAN 40. (To allow VLAN 30 traffic, the native VLAN feature is required, by executing the portmode hybrid command. Refer to portmode hybrid in Interfaces.
