Release Information Statement introduced in Junos OS Release 9.0 for EX Series switches.
Statement updated with enhanced ? (CLI completion feature) functionality in Junos OS
Release 9.5 for EX Series switches.
Description For trunk interfaces, configure the VLANs that can carry traffic.
TIP: To display a list of all configured VLANs on the system, including VLANs
that are configured but not committed, type ? after vlan or vlans in your
configuration mode command line. Note that only one VLAN is displayed for
a VLAN range.
NOTE: The number of VLANs supported per switch varies for each model.
Use the configuration-mode command set vlans id vlan-id ? to determine the
maximum number of VLANs allowed on a switch. You cannot exceed this
VLAN limit because each VLAN is assigned an ID number when it is created.
You can, however, exceed the recommended VLAN member maximum.
On an EX Series switch that runs Junos OS that does not support the Enhanced
Layer 2 Software (ELS) configuration style, the maximum number of VLAN
members allowed on the switch is 8 times the maximum number of VLANs
the switch supports (vmember limit = vlan max * 8). If the switch
configuration exceeds the recommended VLAN member maximum, you see
a warning message when you commit the configuration. If you ignore the
warning and commit such a configuration, the configuration succeeds but
you run the risk of crashing the Ethernet switching process (eswd) due to
memory allocation failure.
On an EX Series switch that runs Junos OS that supports ELS, the maximum
number of VLAN members allowed on the switch is 24 times the maximum
number of VLANs the switch supports (vmember limit = vlan max * 24). If
the configuration of one of these switches exceeds the recommended VLAN
member maximum, a warning message appears in the system log (syslog).
Options all—Specifies that this trunk interface is a member of all the VLANs that are configured
on this switch. When a new VLAN is configured on the switch, this trunk interface
automatically becomes a member of the VLAN.
