Datapath interfaces
The SR-SIM allows the connection of underlying container Ethernet interfaces into SR OS ports, following a standardized naming convention.
The naming convention for SR OS ports
typically takes one of the following formats: L/X/M/C/P,
L/M/C/P, or L/M/P where:
- L: Linecard number
- X: XIOM number (when present)
- M: MDA position
- C: Cage or connector number
- P: Breakout port inside the connector
To ensure automatic connection of datapath interfaces from the container to their
respective SR OS ports, use the following interface naming convention when attaching networks to the
deployed containers: eL-xX-M-cC-P, eL-M-cC-P, or
eL-M-P.
Note: The prefix
e is added at the beginning of
the port, and the forward slash / is replaced with a hyphen
-. Some examples are listed in the following table.| Container interface name | SR OS port name | Expanded description |
|---|---|---|
| e1-2-3 | 1/2/3 | card 1, mda 2, port 3 |
| e1-2-c3-1 | 1/2/c3/1 | card 1, mda 2, connector 3, port 1 |
| e2-2-c3-4 | 2/2/c3/4 | card 2, mda 2, connector 3, port 4 |
| e1-x2-3-4 | 1/x2/3/4 | card 1, xiom 2, mda 3, port 4 |
| e1-x2-3-c4-5 | 1/x2/3/c4/5 | card 1, xiom 2, mda 3, connector 4, port 5 |
