On the SSA switch, you can view the receive and transmit activity on the RX and TX LEDs for the RJ45, SFP, and SFP+ ports. See RJ45 Port LEDs below and SFP and SFP+ Port LEDS.
| 1 = RX LED | 2 = TX LED |
| 1 = RX LED for bottom port | 3 = TX LED for bottom port |
| 2 = RX LED for top port | 4 = TX LED for top port |
Port LEDs describes the LED indications for the RX and TX LEDs for the RJ45, SFP, and SFP+ ports and provides recommended actions.
Port LEDs
| LED | Color | State | Recommended Action |
|---|---|---|---|
| RX (Receive) | None | No link. No activity. Port enabled or disabled. | None |
| Green | Solid: Link present, port enabled, no traffic is being received by the interface. | None | |
