Bypass Menu
Alteon is equipped with an internal bypass feature for its 10/100/1000 copper interfaces. The bypass switch automatically diverts traffic around the appliance whenever the appliance is incapable of passing traffic.
Each pair of static-forwarding ports provides a bypass connection. In case of a failure, they act as a wire and do not block the traffic.
Traffic is bypassed in the following scenarios:

Alteon has no power

Alteon rebooted

Alteon application crashed
All copper ports in the Alteon device are equipped with built-in bypass option. Optical ports do not support a bypass option. (An optical bypass option requires additional hardware that can be purchased separately.)
The bypass configuration (which two ports are connected when bypass is enabled) is as follows:
Port #1 to Port #2, Port #3 to Port #4, Port #5 to Port #6, Port #7 to Port #8.
The bypassed ports are pre-configured in Static-Forwarding mode, and cannot be set with an IP address. This is since the bypass option is hardware fixed, and once bypass is set to On it closes the circuit between the two ports.
Note: HW bypass is supported on specific HW revisions that need to be purchased in advance.
Internal bypass is only supported on Alteon 5208 Bypass platforms.
Internal bypass is only supported in ADC-VX and standalone modes.
Bypass is set globally — enabled or disabled for all bypass ports.
Notes

Bypass is not activated in case of link failure. The Interface Grouping option of the device can be used in such a case.

HA must be disabled in order to enable the internal bypass feature.
Note: Once the bypass switch is activated, the ports will reset and be down for a few seconds.
