892.0. "Loopback for newcomer" by NETRIX::"[email protected]" (Ton Dekker) Mon Apr 07 1997 05:56

Hi,

At this moment I do have (temporarely) a Gigaswitch/ATM, but no systems.
How can I quickly check whether the linecards are working?
I do have two DAGGL-BA (155 Mbps) and two DAGGL-CA (622)
When I put a loopback to any of the ports, it gives the following results:
Port light: blinking amber.      Phy.led: steady green.          Mod.led:off

On the 155 card connecting i.e. port 3 to 4:
Port lights: blinking amber     Phy.leds: steady green          Mod.leds: off

On the 622 card with loopback cable:
Port light: blinking amber      Phy. led: steady green           Mod.led: off

Card 622 to other 622:
Port light: blinking green      Phy.leds: steady amber          Mod.led: off.

Is this how it should look and can I somehow 'see' if packets are being send
and /or received??


thanks. Ton

Blinking amber port LEDs mean that ILMI connectivity has been established -
so at least SNMP/AAL5 packets are getting through.

Green/off for the LEDs right under the PHY connector seems pretty "normal";
I'm not sure whether amber/off is cause for concern or not.
