BondRecipe

class lnst.Recipes.ENRT.BondRecipe.BondRecipe(**kwargs)

Bases: PerfReversibleFlowMixin, CommonHWSubConfigMixin, OffloadSubConfigMixin, BaremetalEnrtRecipe

This recipe implements Enrt testing for a network scenario that looks as follows

                            .--------.
           .----------------+        |
           |        .-------+ switch +-------.
           |        |       '--------'       |
     .-------------------.                   |
     |     | bond0  |    |                   |
     | .---'--. .---'--. |               .---'--.

'-----------------------------'     '----------------'

The recipe provides additional recipe parameters to configure the bonding device.

param bonding_mode:

(mandatory test parameter) the bonding mode to be configured on the bond0 device.

param miimon_value:

(mandatory test parameter) the miimon interval to be configured on the bond0 device.

All sub configurations are included via Mixin classes.

The actual test machinery is implemented in the BaseEnrtRecipe class.

test_wide_configuration(): Test wide configuration for this recipe involves creating a bonding device using the two matched physical devices as slaves on host1. The bonding mode and miimon interval is configured on the bonding device according to the recipe parameters. IPv4 and IPv6 addresses are added to the bonding device and to the matched ethernet device on host2.

host1.bond0 = 192.168.101.1/24 and fc00::1/64

host2.eth0 = 192.168.101.2/24 and fc00::2/64

generate_test_wide_description(config: EnrtConfiguration): Test wide description is extended with the configured IP addresses, the configured bonding slave interfaces, bonding mode and the miimon interval.

generate_ping_endpoints(config)

The ping endpoints for this recipe are the configured bonding device on host1 and the matched ethernet device on host2.

Returned as:

[PingEndpoints(self.matched.host1.bond0, self.matched.host2.eth0)

generate_perf_endpoints(config: EnrtConfiguration) → list[Collection[EndpointPair[IPEndpoint]]]: The perf endpoints for this recipe are the configured bonding device on host1 and the matched ethernet device on host2. The traffic egresses the bonding device.
