1372 | VLAN Stacking
www.dell.com | support.dell.com
• Interfaces configured using Stackable VLAN access or Stackable VLAN trunk commands will not
switch traffic for the default VLAN. These interfaces will switch traffic only when they are added
to a non-default VLAN.
• Starting with FTOS 7.8.1 for C-Series and S-Series (FTOS 7.7.1 for E-Series, 8.2.1.0 for E-Series
ExaScale), 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 should be in hybrid mode. Refer to portmode hybrid.
