The physical interfaces supported by Pica8 switch are shown in Table 1:

Table 1. Physical Interface Supported by Pica8 Switch

Interface Type

Description

GE interface

The GE interface works at the data link layer, provides a maximum transmission rate of 1000 Mbit/s, processes Layer 2 protocol packets, and implements Layer 2 forwarding.

5GE/2.5GE interface

The 5GE/2.5GE interface works at the data link layer, provides a maximum transmission rate of 10 Gbit/s, processes Layer 2 protocol packets, and implements Layer 2 forwarding.

10GE interface

The 10GE interface works at the data link layer, provides a maximum transmission rate of 10 Gbit/s, processes Layer 2 protocol packets, and implements Layer 2 forwarding.

25GE interfaceThe 25GE interface works at the data link layer, provides a maximum transmission rate of 25 Gbit/s, processes Layer 2 protocol packets, and implements Layer 2 forwarding.

40GE interface

The 40GE interface works at the data link layer, provides a maximum transmission rate of 40 Gbit/s, processes Layer 2 protocol packets, and implements Layer 2 forwarding. A 40GE optical interface can work as an independent interface or be split into four 10GE optical interfaces.

100GE interface

The 100GE interface works at the data link layer, provides a maximum transmission rate of 100 Gbit/s, processes Layer 2 protocol packets, and implements Layer 2 forwarding. A 100GE optical interface can work as an independent interface or be split into four 10GE optical interfaces or four 25GE optical interfaces.

Physical interfaces naming in PICOS are specified as follows:

type-1/1/port

The convention is as follows:

  • type - The Pica8 device interfaces use the following types:
    • ge - 1G/5G/2.5G Ethernet interface
    • te - 10G/25G Ethernet interface
    • xe - 40G/100G Ethernet interface
  • port - The port number of Pica8 device. Note that: On the same device, the port number of different types of port starts from 1.

The 100GE and 40GE optical interfaces on Pica8 switch can be used as a single interface or split into four independent interfaces. The 40GE interface can be split into four 10 Gigabit Ethernet sub-interfaces. The 100GE interface can be split into four 25 Gigabit Ethernet sub-interfaces or split into four 10 Gigabit Ethernet sub-interfaces. By default, the 100G interface will be split into 4 x 25GE sub-interfaces.

If the port name of the 100GE or 40GE optical interfaces is xe-1/1/n before port breakout; however, after port breakout the port names of the four sub-interfaces are xe-1/1/n.1, xe-1/1/n.2, xe-1/1 /n.3 and xe- 1/1/n.4. For details about port breakout and merge please refer to Configuring Port Breakout and Merge.
