Chapter XVI. Bypass Driver

Chelsio T5/T4 Unified Wire For Linux Page 224

Getting the default state:

[root@host]# bypass ethX get --default_state

Setting the default state:

[root@host]# bypass ethX set --default_state [bypass |disconnect]

4.2.4. Using the bypass watchdog timer

The watchdog timer is used to ensure that if there is a software failure, the switch will enter the

default state.

First set the timeout value for the watchdog in milliseconds:

[root@host]# bypass ethX set --watchdog_timeout 3000

Start pinging the watchdog:

[root@host]# while true; do bypass ethX set --watchdog ping; sleep 1; done

Enable the watchdog:

[root@host]# bypass ethX set --watchdog enable

4.2.5. Redirect Management

The bypass adapter has the ability to redirect packets based upon rules. Rules can be grouped

into tables. When a rule is added into a table, it is assigned an index. Within a table, rules are

evaluated by index number from low to high. When a rule matches the action associated with it,

that rule is performed and higher number rules are not evaluated. Rules are not evaluated until

a table is activated.
