Channelized Mode on QFX

All the 40g and 100g interfaces will be called with “et” prefix. This is in line with Junos interface naming convention.

10g interfaces will remain to be called “xe”.

If a 40g interface is channelized to 10g, it will be called xe interface with “colon” notation.

On QFX5100-48S and QFX5100-48T switches running Enhanced Layer 2 Software:

• The valid port range for a 10-Gigabit Ethernet interface is 0 through 47 on PIC 0. There are 48 available ports. When you channelize the 6 40-Gbps QSFP+ ports on 0 through 5 on PIC 1, there are 72 available ports.
