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.
| port Numbering | QFX5100 has: 48x 10G: 0 to 47 + 6x 40G: 48 to 53 >>> if using chanalized 10G: port 53 ( 40G) will become 0/0/53:0 ,0/0/53:1 , 0/0/53:2 , 0/0/53:3. suffix is [ 0 - 3 ] QFX5110 has: 48x 10G: 0 to 47 + 4x 40G: 48 to 51 | |||||
