In this article, lets understand how to configure Interface range on Juniper
switch. Interface range can be very useful in a scenario where same
configurations have to be applied to a range of ports. Here instead of going
into each and every port to make the changes, we can make use of this feature
to save time.
so how do we do it ?
Lets configure interface range with the name vlan10 and assign the port
range xe-0/0/5 to xe-0/0/10.
root@vqfx-re# set interfaces interface-range vlan10 member-range xe-0/0/5 to
xe-0/0/10
root@vqfx-re# commit
Lets configure vlan 10.
root@vqfx-re# set vlans vlan10 vlan-id 10
root@vqfx-re# commit
Now Let's assign the configured vlan to the interface range.
root@vqfx-re#
set interfaces interface-range vlan10 unit 0
family ethernet-switching vlan members vlan10
root@vqfx-re# commit
Let's do 'show vlans' and confirm whether the ports in the interface
range vlan10 are assigned to the configured vlan.
root@vqfx-re> show vlans
Routing instance VLAN name Tag
Interfaces
default-switch vlan10 10
xe-0/0/10.0*
xe-0/0/5.0*
xe-0/0/6.0*
xe-0/0/7.0*
xe-0/0/8.0*
xe-0/0/9.0*
To add description to the ports.
root@vqfx-re#
set interfaces interface-range vlan10 description
membersofvlan10
root@vqfx-re> show interfaces descriptions
Interface Admin Link Description
xe-0/0/5 up up
membersofvlan10
xe-0/0/6 up up

xe-0/0/7 up up
membersofvlan10
xe-0/0/8 up up
membersofvlan10
xe-0/0/9 up up
membersofvlan10
xe-0/0/10 up up
membersofvlan10
To disable the ports.
root@vqfx-re#
set interfaces interface-range vlan10 disable
To enable the ports.
root@vqfx-re#
delete interfaces interface-range vlan10 disable
Note:
at the [edit interfaces interface-rang vlan10] hierarchy level the command 'show' will display all the configuration changes added at this particular hierarchy.
{master:0}[edit interfaces interface-range vlan10]
root@vqfx-re# show
member-range xe-0/0/5 to xe-0/0/10;
description membersofvlan10;
