[QFX] Interface-range command and feature for QFabric

0

0

Article ID: KB21836 KB Last Updated: 23 Jul 2018Version: 2.0
Summary:

The Interface-range specification feature allows the specification of a range of interfaces to which subsequent commands are applied. The Interface-range specification feature makes configuration easier since identical commands can be entered once for a range of interfaces rather than being entered separately for each interface.

Symptoms:

 To configure a large number of ports with QFabric.

Solution:

Interface-range is part of the main Junos OS, so the same capabilities / options are inherited in QFabric.  But in QFabric, the range-command only works for a single QFNode.

At FRS, the range command cannot be applied across different QFNodes or within a Server Redundant Node Group or Network Node Group.


Not supported
interface-range access-port {
    member-range Node-1:xe-0/0/0 to Node-5:xe-5/0/47;
}
 

Supported

interface-range access-port {
    member-range Node-1:xe-0/0/0 to Node-1:xe-0/0/47;
    member-range Node-2:xe-0/0/0 to Node-2:xe-0/0/47;
    member-range Node-3:xe-0/0/0 to Node-3:xe-0/0/47;
    member-range Node-4:xe-0/0/0 to Node-4:xe-0/0/47;
    member-range Node-5:xe-0/0/0 to Node-5:xe-0/0/47;
}

The interface range command has to be applied from the SFC -CLI whihc is from the DG directly and not from the individual node-group.
It seems to be a limitation that multiple nodes within same node-group can't be used at once to configur the ports.

Example from lab

set interfaces interface-range Test-Range-1 member-range qf1-nng-3:ge-0/0/6 to  qf1-nng-3:ge-0/0/7
set interfaces interface-range Test-Range-1 disable <-- disable option will disable all the listed ports

In the above statement, Test-Range-1 is the interface-range-name, which is like group-name.
