Physical Interface Numbering Rules

Physical interfaces are numbered in the following way:

A single switch uses slot ID/subcard ID/interface sequence number to identify physical interfaces.
  • Slot ID: indicates the slot where the switch is located. The value is 0.
  • Subcard ID: indicates the ID of a subcard.
  • Interface sequence number: indicates the sequence number of an interface on the switch.
A stacked switch uses Stack ID/subcard ID/interface sequence number to identify physical interfaces.
  • Stack ID: indicates the ID of a stacked switch. The value ranges from 0 to 8.
  • Subcard ID: indicates the ID of a subcard.
  • Interface sequence number: indicates the sequence number of an interface on the switch.

As shown in Figure 2-1, There are two rows of service interfaces on the device. These interfaces are numbered from bottom to top and left to right, starting from 1.

For example, the interface on the top left is numbered 0/0/2.

Figure 2-1  Numbering Diagram

Pay attention to the following points:
  • 10GE interfaces converted from a 40GE interface are numbered based on the number of the last 10GE interface on the switch. For interfaces on the switch panel, if the last 10GE interface is numbered XGE 0/y/m and a 40GE interface to be split is numbered 40GE 0/y/n, the four 10GE interfaces converted from the 40GE interface are numbered XGE 0/y/(m + 4 * (n - 1) + 1). For example, if the last 10GE interface on a switch is numbered XGE 0/0/48, the four 10GE interfaces converted from 40GE 0/0/3 are numbered XGE 0/0/57, XGE 0/0/58, XGE 0/0/59, and XGE 0/0/60. For interfaces on a card, m has a fixed value of 0. For example, the four 10GE interfaces converted from 40GE 1/1/1 on a card are numbered XGE 1/1/1, XGE 1/1/2, XGE 1/1/3, and XGE 1/1/4.

    • y: indicates the subcard number.
    • m: indicates the sequence number of the last 10GE interface on the switch.
    • n: indicates the sequence number of the 40GE interface.
    NOTE:
    Split interfaces are numbered in the same sequence as the wires of a cable are numbered. For example, in a 1-to-4 cable, the wire numbered 1 corresponds to the interface with the lowest interface number, and the wire numbered 4 corresponds to the interface with the highest interface number.
  • On theS5700-52X-LI-48CS-AC, There are two rows of service interfaces on the device and each row has 12 physical interfaces.
    • When SFP optical modules are installed in the interfaces, they are numbered as follows:
      • For interfaces in the bottom row, they are numbered from left to right, with the first in the left numbered 3 and others increased by 4 each time.
      • For interfaces in the upper row, they are numbered from left to right, with the first in the left numbered 2 and others increased by 4 each time.


      For example, when SFP optical modules are installed in the interfaces, the first and second interfaces in the lower left corner are numbered 0/0/3 and 0/0/7 respectively, while the first and second interfaces in the upper left corner are numbered 0/0/2 and 0/0/6 respectively.

    • When CSFP optical modules are installed in the interfaces, each interface is split into two independent interfaces; therefore, the device has 48 interfaces in all. These interfaces are numbered from bottom to top and left to right, starting with 1.



      For example, when a CSFP optical module is installed in the first interface in the lower left corner, the interface is split into two interfaces numbered 0/0/1 and 0/0/3, while the interface in the upper left corner is split into two interfaces numbered 0/0/2 and 0/0/4 when a CSFP optical module is installed in the interface.

    • When CSFP optical modules are installed in some interfaces while SFP modules are installed in others, the interfaces are numbered based on the rule for the installed optical modules.

      For example, when a CSFP optical module is installed in the first interface in the lower left corner, the interface is split into two interfaces numbered 0/0/1 and 0/0/3. When an SFP optical module is installed in the second interface in the upper left corner, the interface is numbered 0/0/6.
