# Trunking
|
|
|
|
The RTL827x allows to combine multiple ports to a single logical port
|
|
(trunking). Up to 2 trunk groups can be defined.
|
|
|
|
## Trunking control
|
|
Two registers RTL837x_TRUNK_CTRL_A (0x4f38) and RTL837x_TRUNK_CTRL_B (0x4f3c)
|
|
define the trunk groups. Each holds a bitmap of ports making up the trunk
|
|
group.
|
|
|
|
## Trunking API
|
|
The code currently provides the following functions:
|
|
```
|
|
void trunk_set(uint8_t group, uint16_t mask) __banked
|
|
```
|
|
|
|
# VLAN configuration on the Serial Console
|
|
For testing the following commands are provided on the serial console:
|
|
```
|
|
trunk <TRUNK-ID> [p1] [p2]...
|
|
create or set a trunk group. Trunk-ID is 1 or 2. ports a physical ports
|
|
|
|
trunk <VLAN-ID> d
|
|
deletes the trunk group
|
|
```
