| - | ====== 18 Bypass network card questions ====== | ||
| - | {{indexmenu_n> | ||
| - | **Why do we recommend to use SILICOM network cards?**\\ | ||
| - | Here are the reasons: | ||
| - | * these cards support bypass functionality; | ||
| - | * drivers' | ||
| - | **Does bypass work in SILICOM cards on power off?** | ||
| - | * Fiber optics bypass does work on power off. It was verified on card PE210G2BPI9-SR-SQ1 short range/ | ||
| - | * The copper bypass does work with no power. It was verified on card [[http:// | ||
| - | **Do SILICOM cards have manual bypass control? | ||
| - | Basically DPI controls bypass by itself.\\ | ||
| - | bpctl_util utility provides manual bypass control, if required:\\ | ||
| - | * bpctl_util all get_bypass - get bypass status; | ||
| - | * bpctl_util all set_bypass on - activate bypass; | ||
| - | * bpctl_util all set_bypass off - disactivate bypass. | ||
| - | **We have got second-hand card. bypass does not work. What can we do?**\\ | ||
| - | The problem is caused by configuring this card as a standard. It means bypass functionality is off.\\ | ||
| - | To diagnose:\\ | ||
| - | |||
| - | bpctl_util all get_std_nic | ||
| - | 07:00.0 dna0 standard | ||
| - | 07:00.1 dna1 slave | ||
| - | 07:00.2 dna2 standard | ||
| - | 07:00.3 dna3 slave | ||
| - | |||
| - | The correct result is: non-standard.\\ \\ | ||
| - | To set the card in bypass mode, one should execute the following instructions: | ||
| - | bpctl_util all set_std_nic off | ||
| - | |||
| - | This instruction switches the card into non-standard mode: it means, with bypass mode. | ||
