Interface Set Caveats

You cannot specify an interface set mixing the logical interface, S-VLAN, or VLAN outer tag list forms of the interface-set statement.

A logical interface can only belong to one interface set. If you try to add the same logical interface to different interface sets, the commit operation fails.

This example generates a commit error:

[edit interfaces]interface-set set-one {interface ge-2/0/0 {unit 0;unit 2;}}interface-set set-two {interface ge-2/0/0 {unit 1;unit 3;unit 0; # COMMIT ERROR! Unit 0 already belongs to set-one.}}

Members of an interface set cannot span multiple physical interfaces. Only one physical interface is allowed to appear in an interface set.

This configuration is not supported:

[edit interfaces]interface-set set-group {interface ge-0/0/1 {unit 0;unit 1;}interface ge-0/0/2 { # This is NOT supported in the same interface set!unit 0;unit 1;}}
