From f52c2721d0a09c03c0db5c08479fb1403fbdc0be Mon Sep 17 00:00:00 2001 From: Claude Date: Tue, 24 Mar 2026 04:17:06 +0000 Subject: [PATCH] Note switch default IP (192.168.1.1) means TFTP needs no console prep Per the ERS 59100 Quick Install Guide, the switch defaults to 192.168.1.1/24 on VLAN 1 if DHCP fails. Method 3 now notes that on a factory/reset switch you can TFTP without configuring anything via console first. https://claude.ai/code/session_01JR2EMK7rwrZJowpstcaxQ6 --- README.md | 10 +++++++--- 1 file changed, 7 insertions(+), 3 deletions(-) diff --git a/README.md b/README.md index 0e35203..794d2a6 100644 --- a/README.md +++ b/README.md @@ -546,17 +546,19 @@ The switch reboots after the agent upgrade. ### Method 3 — TFTP from a laptop (no dedicated server needed) -Your laptop can act as a temporary TFTP server.
