Interface name
For a device operating independently (that is, the device does not belong to any IRF), its interface name
is in the following format: member ID/slot number/interface serial number, where
z
By default, member ID is 1.
z
After a device leaves an IRF, it continues using the member ID when it was in the IRF as its device
ID.
z
Subslot number is the number of the slot in which the LPU resides. For a box-type device, LPUs
are fixed on the device, so the slot number is a fixed value. On the S5120-EI series, the subslot on
