Configuring Dynamic Mixed VLAN Ranges
Dynamic VLAN and dynamic stacked VLAN configuration supports mixed (or flexible) VLAN ranges. You configure mixed VLAN ranges at the [edit interfaces] hierarchy level by specifying the flexible-vlan-tagging statement for the interface and defining up to 32 VLAN and stacked VLAN range groups for use with different VLAN or stacked VLAN dynamic profiles.
 | Note: Junos VLAN IDs for single-tag VLANs are equivalent to the outer tags used for stacked (dual-tag) VLANs. When configuring mixed (flexible) VLANs, any overlap on single-tag VLAN IDs and stacked VLAN outer tag values is supported only for dynamic VLANs on MPC line cards. When configuring mixed (flexible) VLANS on DPCE line cards, overlapping single-tag VLAN IDs and stacked VLAN outer tag values is not supported. This means that a dynamically created single-tagged VLAN interface prevents any overlapping stacked VLAN interfaces from being created or a dynamically created stacked VLAN interface prevents any overlapping single-tagged VLAN interfaces from being created. |
To configure both VLAN and stacked VLAN ranges:
- Access the interface over which you want to create dynamic
VLANs.user@host# edit interfaces ge-0/0/0
- Specify the flexible-vlan-tagging statement to
indicate that this interface is for use with both VLAN and stacked
VLAN ranges.[edit interfaces ge-0/0/0]user@host# set flexible-vlan-tagging
- Define interface automatic configuration values.[edit interfaces ge-0/0/0]user@host# edit auto-configure
- Specify that you want to modify VLAN ranges.[edit interfaces ge-0/0/0 auto-configure]user@host# edit vlan-ranges
- Access the VLAN dynamic profile for which you want to
configure VLAN ranges.[edit interfaces ge-0/0/0 auto-configure vlan-ranges]user@host# edit dynamic-profile VLAN-PROF1
- Specify the VLAN ranges that you want the dynamic profile
to use. The following example specifies a lower VLAN ID limit of 2000
and an upper VLAN ID limit of 3000.[edit interfaces ge-0/0/0 auto-configure vlan-ranges]user@host# set ranges 2000-3000
Note: You can configure multiple dynamic profile associations (up to 32) with different VLAN range groups on each physical interface.
- Specify that you want to modify stacked VLAN ranges.[edit interfaces ge-0/0/0 auto-configure]user@host# edit stacked-vlan-ranges
- Access the VLAN dynamic profile for which you want to
configure VLAN ranges.[edit interfaces ge-0/0/0 auto-configure stacked-vlan-ranges]user@host# edit dynamic-profile VLAN-PROF2
- Specify the outer and inner stacked VLAN ranges that you
want the dynamic profile to use. The following example specifies an
outer stacked VLAN ID range from 3001 through 4000 (to avoid overlapping
VLAN IDs with single-tag VLANs) and an inner stacked VLAN ID range
of any (enabling a range from 1 through 4094 for the inner
stacked VLAN ID).[edit interfaces ge-0/0/0 auto-configure stacked-vlan-ranges]user@host# set ranges 3001-4000,any
Note: You can configure multiple dynamic profile associations (up to 32) with different VLAN range groups on each physical interface.
