Import ieee802-ethernet-interface@2025-09-10.yang, from IEEE 802.3.2-2025, and companion ieee802-ethernet-phy-type.yang, replacing the 2019 revision. Operational interface speed moves to ietf-interfaces:speed, RFC 8343, eth:speed is now obsolete. Bump infix-interfaces.yang revision to track the upgrade. The CLI 'show interface' command renders interfaces as bottom-up layered protocol rows. Ethernet interfaces a new IEEE link-mode row (1000baseT, 10GbaseLR, ...) is added with 'duplex: full|half' in the DATA column. Without link the ethernet row is the first row. Tunnels and wifi follow the same layering: gre/vxlan rows carry remote:/vni: tokens with optional ethernet sub-row for the L2-bearing variants; wifi rows carry 'station' or 'access-point' ssid:, signal:, stations: tokens. admin@bpi-76-8f-c2:/> show interface ⚑ INTERFACE PROTOCOL STATE DATA ⇅ lo loopback UP ipv4 127.0.0.1/8 (static) ipv6 ::1/128 (static) ⇅ br0 bridge DOWN │ ethernet 32:2e:3f:76:8f:c2 │ ipv4 192.168.0.1/24 (static) ⇅ ├ lan0 bridge LOWER-DOWN ⇅ ├ lan1 bridge LOWER-DOWN ⇅ ├ lan2 bridge LOWER-DOWN ⇅ └ lan3 bridge LOWER-DOWN ⇅ gre0 gre UP remote: 198.51.100.7 ipv4 10.255.0.1/30 (static) ⇅ sfp1 ethernet DOWN ca:59:f0:77:80:5b ⇅ wan 1000baseT UP duplex: full ethernet 32:2e:3f:76:8f:c2 ipv4 192.168.0.235/24 (dhcp) ipv6 fe80::302e:3fff:fe76:8fc2/64 (link-layer) ⇅ wan.10 vlan UP vid: 10 │ ipv4 10.0.10.1/24 (static) └ wan ⇅ wan.10.20 vlan UP vid: 20 │ ipv4 10.0.10.20/28 (static) └ wan.10 ⇅ wifi0 wifi UP station ssid: corp-net signal: good ethernet dc:a6:32:00:11:22 ipv4 192.168.7.42/24 (dhcp) yanger populates phy-type and pmd-type from a static ETHTOOL link-mode identity table keyed on (port, speed, duplex). Both leaves are populated for unambiguous media (copper, DAC, copper-T); for generic fiber where the (port, speed, duplex) tuple can map to multiple PMDs (SR vs LR vs ER, etc.) only the phy-type family identity is emitted — guessing the PMD would be misleading. cli_pretty prefers pmd-type (specific) and falls back to phy-type (family) for display. yanger also emits ietf-interfaces:speed and fixes a long-standing 'auto-negotation' typo (yanger had never matched ethtool's correctly- spelled JSON field, so operational auto-negotiation always read 'unknown'). Filling the WG's gap on fixed-speed config ------------------------------------------ IEEE Std 802.3.2-2025 obsoleted the eth:speed leaf without providing a config-true replacement; the standards-correct way to express what older Infix configurations called 'fixed speed' is to restrict the set of PMDs auto-negotiation may advertise. Augment auto-negotiation with two leaf-lists: auto-negotiation/advertised-pmd-types config-true, leaf-list of pmd-type ethernet/supported-pmd-types config-false, leaf-list of pmd-type Pinning a port to a single mode is now expressed as a single-entry advertised-pmd-types list. The kernel-supported set is exposed as operational state for diagnosis — SFP/SFP+ cages report the inserted module's capabilities, narrowing the list to a single PMD when the optic only supports one mode (as suggested by @wkz in PR review). When the supported list collapses to a single entry, yanger uses it to refine the operational pmd-type leaf — more accurate than the (port, speed, duplex) lookup for fiber. confd C apply path (src/confd/src/ieee802-ethernet-interface.c) translates each advertised pmd-type identity to the corresponding ETHTOOL_LINK_MODE_*_BIT_*, ORs them into a mask, and emits 'ethtool --change <if> autoneg on advertise 0x<mask>'. An empty list keeps the historical default of advertising every supported mode. The (legacy) 'auto-negotiation/enable = false' + speed/duplex branch is removed — it has no model representation any more. cli_pretty's detail view gains 'advertised' and 'supported' rows listing the PMDs in each set. A new _pr_label_list() helper unifies multi-row rendering across these new rows and the pre-existing ipv4/ipv6 address rows. The detailed interface view also gains a 'link mode' row carrying the pmd-type / phy-type-derived label. Migration of existing startup configurations -------------------------------------------- Bump confd version 1.8 → 1.9 to trigger the migration on upgrade. share/migrate/1.9/10-ethernet-advertise.sh translates old configs of the form ethernet { auto-negotiation { enable false; } speed S; duplex D; } into ethernet { auto-negotiation { advertised-pmd-types [PMD]; } duplex D; } mapping (S, D) → PMD via a static lookup covering the copper-T speeds the deprecated speed leaf historically supported (10/100/1000/2.5G/ 5G/10G). Interfaces that don't disable auto-negotiation, or that lack a speed leaf, are passed through untouched. Closes #530 Closes #805 Signed-off-by: Joachim Wiberg <troglobit@gmail.com>
Welcome to Infix, your immutable, friendly, and secure operating system! On these pages you can find both user and developer documentation.
Most topics on configuring the system include CLI examples, but every setting, as well as status read-back from the operational datastore, is also possible to perform using NETCONF or RESTCONF. In fact, the Infix regression test system solely relies on NETCONF and RESTCONF.
Tip
The CLI documentation is also available from inside the CLI itself using the
helpcommand in admin-exec mode.
