12.1(8a)EW
Usage Guidelines VLAN 1 parameters are factory configured and cannot be changed.
When you define vlan-name, the name must be unique within the administrative domain.
The SAID is documented in 802.10. When the no form is used, the VLANs SAID is returned to the
default.
When you define the said-value, the name must be unique within the administrative domain.
The bridge bridge-number argument is used only for Token Ring-net and FDDI-net VLANs and is
ignored in other types of VLANs. When the no form is used, the VLANs source-route bridging number
returns to the default.
The parent VLAN resets to the default if the parent VLAN is deleted or the media keyword changes the
VLAN type or the VLAN type of the parent VLAN.
The tb-vlan1 and tb-vlan2 are used to configure translational bridge VLANs of a specified type of VLAN
and are not allowed in other types of VLANs. The translational bridge VLANs must be a different VLAN
type than the affected VLAN; if two VLANs are specified, the two must be different VLAN types.
A translational bridge VLAN will reset to the default if the translational bridge VLAN is deleted or the
media keyword changes the VLAN type or the VLAN type of the corresponding translational bridge
VLAN.
