This is an original planning guide. It is not a vendor manual, an official standard, or legal advice. Example addresses use documentation ranges. Review every command before you paste it.
What this hour is for
How to Configure Inter-VLAN Routing (SVI) on HPE Aruba AOS-S is one lab change on a HPE Aruba AOS-S device you administer. An SVI is the gateway address for one VLAN. Routing between VLANs starts when two SVIs exist and you meant that. The browser tool drafts text. It does not log in. You still choose the device.
AOS-S, the older Aruba switching software, is not AOS-CX. An AOS-CX draft pasted here is the wrong language. Write memory when you mean to keep it. Read the VLAN and the interface back in the AOS-S form. One SVI, one address from the prefix the design already assigned. Not a documentation range pasted into production.
A gateway on VLAN 1 plus a new VLAN in the same hour is two changes. A host uses the SVI as its gateway and reaches one address you named in the same VLAN. The config you copied off the switch first is the rollback.
192.0.2.0/24, 198.51.100.0/24, 203.0.113.0/24, and 2001:db8::/32 are documentation. They belong in the note. They are not prefixes you type onto a production device because they appeared in a draft. example.com is not your hostname. A second session stays open if the change can lock you out.
The change you can finish
Apply nothing during the writing of the note. When the lab window opens, it is one change on the device named in the ticket. Read the draft, then the device, then decide.
Rollback is the file or the revision you saved first. You do not invent a rollback after the only copy is gone.
- Write the hostname and confirm you administer it.
- Save the current config before any draft is applied.
- Generate the draft and delete every line this ticket did not name.
- Remove any 0.0.0.0/0 and any secret.
- Apply one change only when the lab window is open.
- Read the result back and compare it with the ticket.
- Stop. The next feature is a different page.
Mistakes that outlive the command
Inter-VLAN Routing (SVI) on HPE Aruba AOS-S goes wrong in a small set of ways. The list is here so the ticket can forbid them before the window.
- Pasting a draft you did not read.
- The wrong hostname.
- A default password left in place.
- 0.0.0.0/0 kept from a sample.
- A secret in the ticket or in git.
- Two features in one window.
- No saved config before the change.
- A documentation prefix applied on a production device.
- A gateway on VLAN 1 plus a new VLAN in the same hour is two changes.
- Calling the generator output a finished production config.
Decisions to write down
One decision for Inter-VLAN Routing (SVI) on HPE Aruba AOS-S: The hostname matches the ticket. The feature is only Inter-VLAN Routing (SVI). The vendor habit was followed: HPE Aruba AOS-S. A current config was saved first. No 0.0.0.0/0 remains. No secret is in the note. The proof you expect is: A host uses the SVI as its gateway and reaches one address you named in the same VLAN. And the parent pillar still owns the design.
Checks before you call it done
Confirm this before you call the change done: The hostname was read from the device. The saved rollback exists. The draft was edited. One change was applied, or none yet because this was the writing hour. The read-back matches the ticket. A second person can say what changed. Management still works. And the next feature is not started. If one of those fails, stop.
# HPE Aruba AOS-S lab. Review before you paste.
# Feature: Inter-VLAN Routing (SVI).
# AOS-S, the older Aruba switching software, is not AOS-CX. An AOS-CX draft pasted here is the wrong language.
# Delete 0.0.0.0/0.
# prompt-for-this is not a password.
# 192.0.2.0/24, 198.51.100.0/24, 203.0.113.0/24, and 2001:db8::/32 are documentation. They belong in the note. They are not prefixes you type onto a production device because they appeared in a draft.Before you leave the device
How to Configure Inter-VLAN Routing (SVI) on HPE Aruba AOS-S ends when the hostname on the device matches the hostname in the ticket. If it does not, you are on the wrong box. Stop. A command that succeeded on the wrong box is not progress.
The draft stays a draft until a person has read the names in it. A generator does not log into the device and does not know which interface is the uplink. You delete a line that names a device, a zone, or a prefix you did not write down.
