GS728TPP¶

Port map as the library addresses these ports — schematic, not a faceplate layout.

The most unusual entry in the registry: a 28-port Smart Managed Pro switch with 24 PoE+ ports whose SNMP agent implements no Netgear vendor OIDs at all, and whose web UI is an XML API rather than scraped HTML.

[gs728tpp-1]

model ‘gs728tpp’ web UI has no page for get_stats (Per-port octet/packet counters)

[gs728tpp-6] (1,2,3)

model ‘gs728tpp’ registers no Netgear vendor OID subtree, and the logging columns are vendor-only

[gs728tpp-7]

set_flow_control is served only over CONSOLE, SSH, TELNET

[gs728tpp-11]

model ‘gs728tpp’: this model’s SNMP agent cannot create a VLAN: every RowStatus mechanism (createAndGo, createAndGo+name in one PDU, createAndWait->name->active, the name column alone, and createAndGo carrying an egress PortList) is answered inconsistentValue – measured on the device. Membership, PVID and delete DO work over SNMP; create a VLAN over the HTTP backend

Measured behaviour¶

Zero vendor OIDs. A walk of 1.3.6.1.4.1.4526 answers noSuchObject; the sysObjectID of 4526.100.4.27 is only an identifier value, not a data subtree. Everything comes from standard MIBs instead — per-port PoE from RFC 3621 pethPsePortTable, the management IP from ipAddrTable, and the fan and PSU inventory from ENTITY-MIB entPhysical. This is why the readers guard on oids.has_vendor_oids rather than assuming a vendor subtree exists.

Its SNMP carries no live sensor value anywhere — only the inventory. The web UI’s diagnostics list does report health, so the two backends genuinely differ here: a difference, not a bug, and one the support table above states rather than hides.

Its web UI is the GoAhead ``wcd`` XML API. Login is a GET carrying the credentials in the query string — not a form POST — answering <statusCode>0</statusCode> with a session id in a response header. No other model in the registry uses XML_API.

Management-IP writes are unavailable on both backends. SNMP cannot serve them because the mgmt-IP write columns are vendor-only and this agent has no vendor subtree; the web UI ships no page for it. The support table reports both refusals with their reasons.

Protocols¶

SNMP — standard MIBs only, no vendor subtree.
HTTP web UI — the XML_API scheme, GOAHEAD_XML dialect.
