01 Why assistants get end-of-life gear wrong
Language models learn from public text in proportion to how much of it exists. For current platforms from the largest vendors there are millions of pages. For Foundry IronWare there is a thin layer: some archived manuals, scattered forum threads, a few blog posts, and release notes that changed owner twice. The Foundry Networks archive exists partly because that layer keeps thinning. Where the data is sparse, the model interpolates from the nearest dense region, which is usually another vendor's syntax.
Three kinds of mixing follow. Switch versus router code: FastIron shipped Layer 2, base Layer 3 and full Layer 3 images, and commands valid on one are absent on another. Generation and release: a BigIron JetCore module and a later NetIron chassis share a family resemblance but not a command set, and the successor owners kept the names while changing the software. Other vendors: the dominant industry CLI leaks in wholesale.
02 How to verify an answer on the device
- Start with show version. It gives the platform, the image type (switch or router code) and the exact release. An answer that does not name those three things has not been checked against your device.
- Walk the CLI with ? help. Enter each command up to the keyword in question and type
?. If the keyword is not offered at that level, it does not exist on this image, whatever the answer claims. - Cross-check the model and generation. Confirm the answer is about your family and era: FastIron edge switches and NetIron routers are not interchangeable, nor are pre- and post-acquisition releases.
- Test on the least important port first. Apply to an unused interface or a lab unit, then check with
show running-configthat the line was accepted as written.
sw1# show version (note platform, image type and release from the output) sw1# configure terminal sw1(config)# vlan 20 by port sw1(config-vlan-20)# ? (tagged, untagged and router-interface are offered) sw1(config-vlan-20)# switchport mode trunk Invalid input -> switchport mode trunk (foreign syntax: IronWare trunks with tagged ethernet 1/1)
03 Tell-tale signs of a bad answer
| Sign | What it suggests |
|---|---|
switchport keywords under an interface | Syntax borrowed from another vendor |
| Port names like Gi0/1 | Foreign naming; IronWare uses ethernet slot/port or unit/slot/port |
copy run start as the only save | Generic habit; IronWare's native save is write memory |
| Layer 3 commands on a Layer 2 image | Switch and router code confused |
| A flag with no release named | Possibly invented; confirm with ? help |
| Confident answer, no caveats | No signal either way; verify regardless |
The native IronWare command forms on this site are the quickest cross-reference, and the same verification discipline applies to any generated change, as set out in the review pipeline for machine-written configs. Protocol behaviour that did not change between vendors, such as spanning tree timers, is where generated answers are most often right.
Never paste a generated password recovery or boot monitor sequence onto a unit you cannot reach by console. The verified procedure is in console access and password recovery.
04 Provenance of archived documentation and forum posts
Human sources need checking too. For an archived manual, establish the title, the software release it covers, the date and where the copy came from: a web archive capture of the original domain carries more weight than a re-uploaded PDF with no history. For forum posts, prefer threads where the poster quotes command output from a named release, and treat a single unconfirmed reply as a lead, not a fact. Documents rehosted after the acquisition and renames sometimes changed product names while keeping old content, so match the release, not the logo.
05 This archive's sourcing policy
FoundryNet is an unofficial, independent archive and is not affiliated with Foundry Networks or any successor company. Pages here summarise in our own words; we do not reproduce documentation text. Every factual page lists its sources in plain text, dates are marked approximate where we could not confirm them, and command examples are labelled illustrative. We do not publish generated command syntax that has not been checked against documentation or a device. Corrections with a source are welcome through the contact page.
Keeping trustworthy copies of the manuals in the first place is covered in archiving discontinued vendor documentation.
06 Questions
Why do chat assistants give wrong IronWare commands?
Training text about IronWare is sparse and outnumbered by other vendors' syntax, so models fill gaps by analogy. The result mixes switch and router images, releases and foreign keywords, all written with equal confidence.
What is the fastest way to check a suggested command?
Run show version to confirm platform, image and release, then walk the command with ? help at each level. If the keyword is not offered, the command does not exist on that image.
Is switchport mode trunk valid on a Foundry switch?
No. That is another vendor's syntax. IronWare defines a port-based VLAN and adds ports as tagged or untagged members inside it; a tagged port carries multiple VLANs.
How can I tell if an archived Foundry manual is genuine?
Look for a title, release number and date, and trace the copy to a web archive capture of the original site or another source with history. Match the software release to your device rather than trusting the product name.
Is this site affiliated with Foundry Networks or its successors?
No. FoundryNet is an unofficial, independent reference and archive. It is not affiliated with, endorsed by or connected to Foundry Networks or any company that acquired its products.
