SUMMARY

The hp_procurve_show_system template fails to parse output from Aruba 2930F switches configured with VSF (Virtual Switching Framework) stacking.

On VSF-stacked switches, the show system output format differs from standalone switches in two ways:

1. Software revision and Base MAC Addr appear on separate lines instead of the same line
2. Per-member sections (VSF-Member :1, VSF-Member :2, etc.) appear with individual serial numbers, MAC addresses, memory stats, and uptime — none of which are matched by the current template

The template has no rules to match any of these lines, so it returns incomplete/empty data (no serial number, no MAC address, no ROM version).

VSF stacking is a widely used feature on Aruba 2930F/2930M series switches in enterprise campus networks. Having a mix of standalone and VSF-stacked switches in the same network is very common.

EXPECTED RESULTS

Test 1 (VSF): The template should return one record per VSF member (consistent with how aruba_aoscx_show_vsf_detail handles VSF), with a new MEMBER_ID field:

parsed_sample:
  - member_id: "1"
    name: "lab-sw-01"
    software_version: "WC.16.11.0027"
    rom_version: "WC.16.01.0010"
    serial: "AB12CDE3FH"
    mac_address: "a1b2c3-d4e5f0"
    uptime: "84 days"
    cpu_util: "0"
    mem_tot: "333,451,776"
    mem_free: "210,899,116"
    # ... other fields
  - member_id: "2"
    name: "lab-sw-01"
    software_version: "WC.16.11.0027"
    rom_version: "WC.16.01.0010"
    serial: "AB34CDE5GJ"
    mac_address: "a1b2c3-f7e8d9"
    uptime: "84 days"
    cpu_util: "0"
    mem_tot: "333,451,776"
    mem_free: "227,954,500"
    # ... other fields

Test 2 (Standalone): Should continue to return a single record with an empty member_id — fully backward compatible with all existing fields populated.

ACTUAL RESULTS

Test 1 (VSF) — most fields are empty:

Test 2 (Standalone) — works correctly:

======================================================================
TEST 2: Standalone switch (no VSF)
======================================================================
Number of records returned: 1

Record 0:
  NAME: "lab-sw-02"

  MAC_AGE: "300"
  TIMEZONE: "2"
  DAYLIGHT_RULE: "Western-Europe"
  SOFTWARE_VERSION: "WC.16.11.0020"
  ROM_VERSION: "WC.16.01.0010"
  ALLOW_MODS: ""
  MAC_ADDRESS: "b2c3d4-e5f6a7"
  SERIAL: "CD56EFG7HK"
  UPTIME: "141 days"
  CPU_UTIL: "0"
  MEM_TOT: "333,517,312"
  MEM_FREE: "212,260,288"
  PACKETS_RX: "2,096,454"
  PACKETS_TX: "2,127,453"
  PACKETS_TOT: "6600"
  BUFFERS_FREE: "4347"
  BUFFERS_LOWEST: "4315"
  BUFFERS_MISSED: "0"

As shown above, the template works correctly for standalone switches but returns empty values for all critical fields (SOFTWARE_VERSION, ROM_VERSION, MAC_ADDRESS, SERIAL, UPTIME, CPU_UTIL, MEM_TOT, MEM_FREE) when parsing VSF stacked switch output.

Note: I have a working fix for this template and I'm happy to submit a PR with full test data including both standalone and VSF raw outputs. The fix adds a MEMBER_ID field (following the precedent from aruba_aoscx_show_vsf_detail) and returns all VSF members as separate records.

Hi @molhamalnasr

Ah, 2930F runs AOS-S and those switches have the same output as hp_procurve (HPE) switches, doesn't it?

We'd be happy to review your PR.
Please be sure to include the test data as instructed in the development docs.

[molhamalnasr]

Hi @mjbear

Yes, exactly. The Aruba 2930F runs AOS-S firmware (WC.16.x.x) and uses the same CLI and output format as the hp_procurve platform in ntc-templates. The show system output is identical in structure to other HPE ProCurve/AOS-S switches.

The issue is specifically when VSF (Virtual Switching Framework) is enabled — the output format changes from a single block with all fields to a shared header followed by per-member sections (VSF-Member :1, VSF-Member :2, etc.) with a reduced set of fields. The current template only handles the standalone (non-VSF) format.
