Subject: [PATCH] feat(netinfra): prep LACP conversion commands for cross-rack
 trunk [#369]
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The cross-rack trunk (ch1, 4×1G) between core-sw01 and tor3-stor is
still static mode=on — no failure detection if a cable dies. Adding
command files to convert both switches to LACP during Friday's
maintenance window. Core hash stays layer-2-3 (5448 hardware limit);
stor hash stays layer-2-3-4 (already set).

+! RISK: Brief storage-net outage during transition (seconds)

+! Current: g13-g16 in ch1, mode=on (static, no failure detection)

+!       tor3-stor hash stays layer-2-3-4 (already set)
+!
+! IMPORTANT: Run this SIMULTANEOUSLY with tor3-stor change.
+!   If one side is LACP and other is static, trunk goes down until
+!   both sides match. Plan for ~30s storage-net outage.
