Raw

fwd.b — Forwarding, Port Isolation, Rate Limits, Per-Port VLAN

One endpoint backing three UI pages: Port Isolation, Forwarding and VLAN (the per-port VLAN settings — the VLAN table is vlan.b). One record; per-port bitmasks/arrays. Not polled (read once, then written on Apply).

Port isolation matrix

Label SwOS id Lite id Type Access Notes
From Port n (n = 1…N) fp1 … fpN i01 … i0N (hex: port 10 → i0a) bool (mask) RW fpn bit p = forwarding allowed from port n (1-based) to port p (0-based). Default: everything allowed except the port itself

The full matrix is N properties × N bits. css106 exposes the same fp1–fp6 ids on its Forwarding page. Not available on Lite ftc21/gpen21/gper14i.

Forwarding page

Label SwOS id Lite id Type Access Availability / notes
Port Lock lck i10 bool (mask) RW all
Lock On First lckf i11 bool (mask) RW all
Set As Uplink Port – i1f bool, radio (single port bit) RW Lite ftc21, gpen21, gper14i only
Mirror Ingress imr i12 bool (mask) RW not on Lite ftc21/gpen21/gper14i
Mirror Egress omr i13 bool (mask) RW ditto
Mirror To mrto i14 bool, radio (single port bit) RW ditto
Storm Rate srt i1a SwOS: uint 1–100 (percent). Lite: uint, unit 100 kbit/s, max 65535 RW not css106
Limit Unknown Unicast suni i1b bool (mask) RW not css106
Flood Unknown Multicast fmc i1c bool (mask) RW not css106, not Lite ftc21/gpen21/gper14i
Ingress Rate ir i1d SwOS: uint, kbit/s (UI accepts k/M/G). Lite: uint, unit 100 kbit/s, max 65535 RW not css106
Egress Rate or (css106) i1e css106: uint, metric. Lite: uint, unit 100 kbit/s RW not in SwOS 2.18 (css106 and Lite only)

VLAN page (per-port VLAN behaviour)

Label SwOS id Lite id Type Access Notes
VLAN Mode vlan i15 enum — SwOS/css106: disabled, optional, enabled, strict; Lite: disabled, optional, strict RW per port
VLAN Receive vlni i17 enum: any, only tagged, only untagged RW per port
Default VLAN ID dvid i18 uint array, 1–4095 RW per port
Force VLAN ID fvid i19 bool (mask) RW per port
VLAN Header (egress) vlnh – enum: leave as is, always strip, add if missing RW css106 only — newer firmware moves egress tagging to the VLAN table membership (vlan.b)

Relationships

  • dvid is applied to untagged ingress traffic; fvid forces it even on tagged traffic.
  • mrto/i14 (and i1f) are radio-style bitmasks: exactly one bit set.
  • The ACL action Mirror (acl.md) sends to the same mrto mirror target.
